Editorial standards and corrections
How our guides are made, what we will and won't claim, and every correction we have published.
How the guides are made
Tendground is a small, independent publication, published by Tendground, Inc. (details on our about page). Our guides are researched and drafted with the help of AI tools, then checked against the sources they cite: every study link has to resolve to the paper it names (all 174 did when we last audited them), and since September 2026 every drug statement in a new medication guide is checked against the drug's official label before it goes live. The byline "Tendground Editorial" means the publication stands behind the piece; it does not stand for a named expert. The illustration at the top of each guide is generated with an AI image tool; it is an illustration, not a photograph of a venue, product or treatment we describe.
Nobody at Tendground is a doctor, therapist or licensed practitioner, and our guides are not reviewed by one. They are general information, not medical advice.
What we never claim
- That we visited, stayed at, tested or tried a place or a product. We research from what businesses, labels and studies publish.
- That a directory listing is a recommendation. Listings are compiled from public sources; see how we verify.
- That a practice treats, cures or prevents a condition.
- A price, a number or a study we have not read ourselves.
How we source health information
Our medication and condition guides cite primary sources in the text: FDA drug labels, NIH and PubMed records, the CDC, and professional societies. A named study gets its authors, journal and year and a link. Medication guides give no dosing and never tell anyone to change, stop or time a medication; that decision belongs to the prescriber.
Many of our older explainers do not cite sources yet. We are adding them, starting with the pages people read most, and we do not describe a page as evidence-based where it is not sourced.
What the dates mean
"Published" is the day a page first went live. "Updated" appears only after a substantial rewrite or a factual correction, never after a wording change or a new title.
"Sources checked" appears under the byline when we hold a dated record of the check. Each statement it counts is one the page makes, matched to a quote copied word for word from its source, and we keep that quote with the date we read the source. Only outside sources count: a statement checked only against one of our own pages is left out. When we change a page, we recount. The line says how many statements were checked, not that every sentence on the page was. Pages without the line have not had this check yet; we are working through them, starting with the health and medication guides people read most.
Corrections
When we get something wrong, we fix the page and log it here. To report an error, use our contact page.
- : Sauna or hot tub after a treatment: the hub gave two hours after Botox and 24 hours after laser hair removal as settled rules and linked a 2012 leaflet replaced in 2024. Published advice now reads about 4 hours for Botox, and laser reads a day to a week by clinic. It said one of seven sources names a sauna; three do. It had no 911 line or urgent signs.
- : Kidney stones: the guide had no 911 line near the top, called water the one intervention with a randomized trial, called any moving stone an emergency where the sources say stone pain with fever, and limited its fever and procedure rules to hot tubs. They now cover saunas, steam and hot yoga. We found no study of saunas in people with stones, and the guide now says so.
- : Eczema and psoriasis: signs of pustular psoriasis and of infected eczema were filed under seeing a doctor promptly; the NHS sends them to urgent or emergency care. The guide said floats are usually fine on intact skin with no study behind it, and that the cautions were not skin specific where NIAMS lists heart attack and stroke among psoriasis risks.
- : Tretinoin and retinoids: the guide had no pregnancy line, though the Tazorac label says contraindicated in pregnancy, and no 911 line. It said no label mentions heat, where Tri-Luma names heat as a weather extreme, and treated waxing as an adapalene rule, where other retinoid labels and MedlinePlus cover it.
- : Minoxidil: the guide had no 911 line, blamed a drop on standing for the sauna risk where the label says minoxidil does not itself cause it, credited the label with a dry scalp rule that comes from MedlinePlus, and softened the leaflet's call immediately to report.
- : Botox, filler, testosterone, breathwork retreats, pregnancy, fainting, sunburn and other guides: lines that rested on sources whose terms forbid automated access now rest on sources we can read, or were narrowed or removed. After Botox, published advice reads about 4 hours, not two. After filler, the 24 hour heat wait stands and the advice not to rub the area now reads a week.
- : Nine health guides (isotretinoin, laser hair removal, atrial fibrillation, blood thinners, doxycycline, cannabis, acid reflux, GLP-1 drugs, CGM and pumps): lines that rested on sources whose terms forbid automated access now rest on the NHS, NIH institutes, MedlinePlus health topics and the labels. Where nothing we could read said the same, the claim was narrowed or removed, among them that isotretinoin dryness clears when the drug stops, a 5 to 10 minute bath rule, and a cupping list said to name heart disease.
- : Thyroid conditions: the guide called a cold plunge miserable rather than dangerous with an underactive thyroid; a 2026 consensus of thyroid and endocrine societies names cold exposure among the triggers of myxedema coma, the rare emergency of severe untreated hypothyroidism, and the guide now says the plunge waits until the hormone is replaced. It said no pose, detox or supplement changes a hormone level, where NIDDK says iodine and kelp supplements can cause or worsen thyroid disease. It had no 911 line.
- : Lupus: chest pain, breathlessness and new numbness or confusion were sent to the rheumatologist; they now mean 911, and the guide has a 988 line. It said there was nothing lupus specific about cold water for people without Raynaud's, where lupus raises heart risk, and it cited a 2019 EULAR update for exercise that its text does not contain.
- : Testosterone: the guide put chest pain and sudden breathlessness under urgent care; they now mean 911. It said the AndroGel 1.62% label lists no sweating, where it lists sweating and hot flushes, and it left out the gel label warnings for women and on blood pressure.
- : Laser hair removal: the guide gave 24 hours as the rule for heat, where an NHS laser service asks for seven days, and linked a 2012 leaflet replaced in 2024. It had no line on when a burn or blister needs urgent care, or on keeping numbing cream away from heat.
- : New piercing: the guide called the signs of infection reasons to get it checked; the APP says see a doctor immediately, and sepsis signs mean 911. It had no line for people with diabetes or a weak immune system.
- : Atrial fibrillation: the guide sent chest pain, breathlessness and fainting to urgent care and never listed stroke signs; they now mean 911. It called a cold plunge a question for the cardiologist, where Harvard Health says anyone with a heart rhythm disorder should avoid cold plunges, and it now says to skip it unless the cardiologist says yes. It said patients often report episodes after a sauna or a hot bath, with no source, and called three triggers proven where the trials prove alcohol.
- : Acid reflux and hiatal hernia: vomiting blood, black stools and chest pain that could be the heart were filed under seeing a doctor promptly; they now mean urgent care or 911. The guide called breathing the one practice with a randomized trial, said nothing can move a hernia back, and stated as fact that heat does nothing to reflux.
- : Glaucoma: the guide treated a brief downward dog as fine, where two studies found it raised eye pressure most and from the moment the pose was taken. It had no instruction for a sudden painful red eye; it now says go to the doctor or an emergency room immediately, as the National Eye Institute does. It said saunas and cold water carry no glaucoma caution, where a case report describes pressure spikes after sauna sessions in severe glaucoma, and it said eye yoga does nothing, which small trials contradict.
- : Ozempic, Wegovy and Mounjaro: the guide had no 911 line, left out that the labels say to stop and call right away for severe stomach pain that will not go away, and said neither label warns about heat, where both warn about heat for the pen. It said you drink less without noticing and gave a waiting time after a dose, neither with a source.
- : CGM and insulin pump: the guide had no 911 line for severe low blood sugar, said Tandem's pages remind you to disconnect before submerging where they offer a temporary disconnect, linked an older Medtronic guide, and cut Abbott's advice to consult a health care professional immediately if you believe you are dehydrated.
- : Minneapolis saunas: Embrace North lists its saunas at 190 to 200F and its cold plunge at 40 to 45F, not 200F and 38F to 43F, and its site now prints its prices.
- : Blood thinners: after a head knock the guide said to call the care team the same day; the federal AHRQ guide says to call your doctor and go to the hospital immediately after a fall or a hit to the head, even with no bleeding, and the guide now says so, with a 911 line. It also linked the wrong Europace paper, named Coumadin, a discontinued brand, called deep tissue work designed to bruise, said heat and cold were otherwise fine, and called moderate massage fine without first asking the care team.
- : Antidepressants: the guide had no 988 or 911 line and did not mention the boxed warning on suicidal thoughts. It called low blood sodium on SSRIs rare, where its own source puts it at 0.5% to 32% of patients in the reports, said to drink less alcohol where the Zoloft, Lexapro, Prozac and Effexor XR guides say not to drink, and sent serotonin syndrome signs to prompt care rather than the emergency room.
- : Doxycycline and antibiotics: the guide said the label treats a skin reaction in the sun as a reason to reconsider treatment; it says treatment should be discontinued at the first sign of skin redness. It said to stop a course only on the prescriber's word, where the ciprofloxacin guide says to stop at once at the first sign of tendon pain, allowed a sauna with mild symptoms of an infection, and had no 911 line or the label's warning on C. difficile diarrhea.
- : Isotretinoin (Accutane): the guide had no 988 or 911 line and said to tell the prescriber about a mood change; the label says to stop the drug and tell the prescriber right away. It now states the boxed warning on birth defects, and its table keeps peels, laser, microneedling and dermaplaning off for at least six months after the course, as the label does for resurfacing.
- : Cannabis and the sauna: the guide had no 911 line for a faint, the risk it is built around, listed an unheated hot yoga class while high as fine with no source, said a review called the release of THC from fat slow and variable when it says slow, and left pregnancy out. It cited a CDC heart page we could not read; that point now rests on NIDA.
- : Does a sauna help with depression, and can cold water help depression and anxiety: neither guide carried a crisis line. Both now open with 988 and 911.
- : What to do if your studio closes: the guide gave only a card network's 120-day window. A federal credit card billing error notice has its own 60-day clock, and both are now stated.
- : Cryotherapy, ice bath and after-workout plunge guides: they called the cold mood lift real. The studies measured hormones, not mood, and a 2025 review found no improvement in mood. The cryotherapy guide also overstated the hormone rise. How often to sauna or plunge said daily use is fine if you feel good; Cleveland Clinic says once or twice a week for beginners.
- : Shin splints and Achilles pain, vibration plates and acupressure mats: the first left out compartment syndrome, blood clots and fluoroquinolone tendon risk; the second left out falls and said bone results were promising, where a 2024 overview does not recommend it; the third cited small trials on back pain we could not find, and called the mats harmless.
- : Box breathing and progressive muscle relaxation: neither had a 988 or 911 line or NCCIH's caution on rare reports of harm. Muscle relaxation said it helps sleep against NCCIH's reading, and its count of muscle groups and minutes was wrong.
- : Sauna blanket vs a real sauna: the guide had no burn warning, 911 line or who-should-check line. It now cites the CPSC recall of about 78,000 blankets after 32 reports of burn injuries, and its unsourced price band is gone.
- : Osteoarthritis: the guide called a hot, red, swollen joint a question for a clinician; the NHS says it needs urgent help, because it can be an infected joint. It also left out that the American College of Rheumatology conditionally recommends against massage for the symptoms.
- : Where to find a cold plunge: the guide said you can stop a bathtub of ice instantly; Washington's health department says lost strength and coordination can make it hard to get out. It had no 911 line, no who-should-skip section and no time limit, said a private slot suits nervous beginners, pitched open water with no life jacket, and stated hygiene as a guarantee that stand-alone tanks cannot meet. It now covers venue types with printed prices and what to ask.
- : Chronic fatigue and long COVID: the guide gave a sauna recipe and said how you feel in the room tells you nothing, which tells someone who may have POTS to ignore faintness. No health body we read recommends a sauna for these conditions, and Johns Hopkins's fatigue clinic brochure says to avoid them. The 48-hour wait had no source. It had no 988 or 911 line, and it now quotes NICE on pacing.
- : What to expect at a wellness retreat: the guide called a day-two dip normal and a sign it is working; we found no study of one. It said to tell the host on day one so they can support you, where hosts screen before you arrive and one says it is unable and unqualified to provide that care. It now has 988 and 911 near the top, who should wait, and eight programs' printed days and rules on leaving. A line in the first silent retreat guide that told readers not to leave was removed.
- : Wellness after birth: the guide said massage is often fine within 1 to 2 weeks, a figure with no source; we found no published rule, and your OB or midwife decides. It had no 911 line, warning signs or crisis lines, gave blood clots one clause (ACOG gives a risk window of 4 to 6 weeks after birth), and said not to swim while bleeding where the NHS says to wait until 7 days after bleeding stops. It said relaxin persists for months; a 1989 study found none in the blood at 6 weeks.
- : Anxiety and claustrophobia in wellness spaces: the guide told readers that knowing a racing heart is ordinary would make panic less likely; Cleveland Clinic says panic and a heart problem are tough to tell apart, so chest pain, trouble breathing or fainting now means 911, at the top of the page with 988. It said float tanks often go better than expected; Western Australia's health department says they are not recommended if you experience claustrophobia. It said every door opens from the inside with no attendant; some venues print a locked room. It gave exposure targets with no source.
- : Kidney stones: the guide called fever with stone pain an emergency without saying what to do, and left out chills. It now says to call 911 or go to an emergency room.
- : Why contrast therapy works is now part of our contrast therapy guide. The title held only for less soreness than plain rest after hard exercise; the circulatory pump explanation did not hold up, safe every day had no source, and the page had no 911 line. The guide's own line that no trial measured mood after a sauna and plunge cycle was also wrong: one small study did.
- : How to cancel a wellness membership: the guide said a hard cancellation is not a scam but the business model, and that following the gym's process leaves you clear. New York's Attorney General has sued a gym over what the office calls illegal cancellation policies, and a reader can still owe a commitment, a buyout or a final payment. It now gives the status of the FTC's rule, five states' rules and the deadlines for card and bank disputes.
- : Are wellness memberships worth it: the guide said a membership pays off at about three visits. At the 26 venues in our price index that publish both prices the median is 4.0, and 22 break even above three. Its worked example had the wrong sum and used a pair of prices no venue prints.
- : Sauna or cold plunge first: the guide treated the switch from hot to cold as routine, had no 911 line, said to leave when your body says done (the CDC says a person may not notice low body temperature), and credited cold with a mood lift that a 2025 review did not find. We found no trial comparing the two orders, and the guide now says so and sets out what the studies measured.
- : Sauna vs hot tub: the guide did not mention drowning or 911, called a 15 to 20 minute soak productive where the public spa rules we read set 15 or less, called the tub the mild option, and said hot tubs rather than saunas are singled out in pregnancy; ACOG and MotherToBaby name both. It had nothing on Legionella or on hair and drain entrapment. We found no trial comparing the two for recovery, and the guide now says so.
- : Infrared vs traditional sauna: the guide told readers who find high heat hard to choose infrared, with no line on who should check first, and gave 25 to 45 minutes, which no source we read prints; Cleveland Clinic says to check first if over 65 or with a pre-existing condition, and 20 to 30 minutes. It said the evidence was built almost entirely on Finnish saunas and that core temperature ends up similar if you stay long enough; neither holds. 24 other pages with the same lines were corrected, including advice to first-timers of 20 to 30 minutes, where Cleveland Clinic says five to 10.
- : Women's wellness retreats: the guide had no crisis line and told people running on fumes that silence would serve them better; Spirit Rock says silent retreats are best engaged when healthy, and the Insight Meditation Society says one may not be appropriate after recent considerable trauma or with significant depression, anxiety or PTSD. It called plant-medicine ceremony legal with no source, gave everyone a sauna, cold and breathwork routine, and printed a price range that hosts' own prices fall outside in both directions. It now lists 25 named programs with the dates and prices their hosts print.
- : Miraval vs Sensei: the two comparisons of this pair are now one page, with what each resort prints, dated; earlier versions had no sources and carried prices and program claims we could not support.
- : Cold plunge and sauna temperature and time: the guide gave 50 to 59F for 2 to 5 minutes as a safe starting envelope; Cleveland Clinic says a minute or two for beginners and never over five minutes or below 40F. It said cold shock gets sharper below 50F; the National Weather Service says it can be as severe at 50 to 60F. We could not trace the 2 to 5 minutes to a study. Three studio figures were corrected, which also moves the median on our statistics page to 39F.
- : Is cold plunging safe: the guide had no 911 line or warning signs, said the risk is not hypothermia (Cleveland Clinic lists it first), called the heart response unremarkable in healthy people, said to get out before you stop shivering (shivering that stops is a hypothermia sign), gave afterdrop minutes no source sets, and left out many people told to avoid or ask first.
- : Float tank guide: the list of who should not float left out kidney disease, heart problems, contagious illness, psychosis, and alcohol or sedatives, and it had no crisis line and nothing on fainting. It said magnesium is absorbed through the skin and that the research is consistent; neither holds. Its hygiene claims and prices had no source.
- : What is a sound bath: the guide said the main risk is falling asleep and that there are no general contraindications; venues publish their own. It called crystal bowls a gentler start for sound-sensitive people with no source, had no crisis line, said reasonable evidence where reviews say they cannot recommend it, and gave prices and session lengths no venue prints.
- : Is breathwork safe: the guide said fainting is fine lying down with a facilitator nearby; MedlinePlus says to be seen, because it may be a seizure or a heart rhythm problem. It had no 911 or 988 line, softened who should avoid fast breathing to who should get clearance, called tetany usually harmless (Cleveland Clinic says severe tetany can be life-threatening), and overstated deaths. It now sets six published lists side by side.
- : Couples wellness retreats: the guide said nothing on abuse while sending struggling couples to therapist-led formats and places with no phone signal; it now gives the National Domestic Violence Hotline first. It recommended a winter sauna then a cold dip in a pond or river with no warning, carried unsourced price bands, and did not mention flash floods. The title no longer says best.
- : Solo wellness retreats: the guide said where it is safe on the strength of its own checklist; we have not visited or vetted any retreat and found no published safety data. It had no crisis line or who-should-wait guidance, said we read every reply and would point you somewhere honest, carried unsourced price bands, and did not mention flash floods on Hill Country rivers. The title no longer says best.
- : IV therapy and vitamin drips: the guide told readers recovering from significant dehydration to book a drip; MedlinePlus calls severe dehydration a life-threatening emergency. It named infection as the only risk, called the one placebo trial of the Myers Cocktail unblinded with modest results (it was double-blind and found no difference from placebo), missed FDA's August 2026 notice on IV glutathione, and oversold vitamin C in cancer care.
- : Safety lines corrected on 15 older guides ahead of their full review. Lower back pain and sciatica said new loss of bladder or bowel control or saddle numbness needs a doctor soon; that is an emergency. Sauna or cold plunge first said warming up avoids cold shock; we found no evidence for that. What to expect at a retreat called a bad second day a sign it is working and told readers to push through; it now says tell staff, leaving is fine, and 988 and 911. Reiki was called safe for children and people with serious illness. Massage vs chiropractic left out the rare risk of stroke from neck manipulation. Jaw pain missed giant cell arteritis, and aromatherapy allowed swallowing oils on an aromatherapist's advice. The stroke lines now say call 911.
- : A home steam room: the guide called a portable steam cabinet low risk and told readers to buy one first; CPSC recalled about 1,000 portable steam saunas in May 2026 after reports of burns. It said nothing on burns, scalds, children, pregnancy, heart conditions or slipping, called steam plumbing straightforward where the makers name scald hazards, and gave total cost ranges no maker prints; those are gone.
- : Sauna types explained: the guide suggested milder rooms for older users and anyone easing back after illness, offered infrared if high heat is unsafe for you, and answered a harsh throat with a steam room, against what Cleveland Clinic and Asthma + Lung UK say. It recommended smoke saunas with no carbon monoxide warning, had no who-should-check section, and said almost all sauna research is Finnish (in a 2018 review, 25 of 40 studies were infrared).
- : Mud baths and clay treatments: the guide had no emergency line, listed too few people who should skip a mud bath, and never mentioned eating clay (FDA has warned of elevated lead in a clay product). Its claims that reputable venues refuse and sanitise, its temperature and its prices had no source, and it said there was no cardiovascular research where studies exist. It now lists what five Calistoga spas print.
- : What to do after a cold plunge: the guide had no 911 line and no signs of hypothermia, and said warm, dry, moving and unhurried is the whole recipe. It ranked rewarming above the plunge, though the sources put the sharpest danger in the first minute in the water, gave afterdrop minutes no source sets, and called a sauna afterwards fine. It said nothing on going alone, alcohol, children, or fainting.
- : Can you drink alcohol in a sauna: the guide said a morning sauna after a few drinks is usually fine; a Finnish paper warns that sauna bathing during the hangover phase creates real health risks.
- : Does anything cure a hangover: the guide gave no alcohol overdose signs or 911 line, and recommended an anti-inflammatory over paracetamol with no stomach warning, where MedlinePlus says to avoid acetaminophen for a hangover. It called IV risks small, said hangovers are hypotensive (NIAAA lists increased blood pressure), said the offers are legal (FDA sent warning letters on hangover supplements in 2020), and had no warning about driving or withdrawal.
- : Sauna, cold plunge and your menstrual cycle: the guide stated as fact that heat feels harder after ovulation, where the closest study found comfort similar, and gave dose rules by phase that no source sets, including going longer or hotter in the follicular phase. It said nothing on heavy bleeding, anemia, toxic shock, or a possible pregnancy in the luteal phase, and said every studio expects you to come on your period, where some spas bar it.
- : Sauna vs hot tub: the guide said a hot tub's total heat load is much smaller than a sauna's; in a 2025 head-to-head study, core temperature rose 1.1 C in hot water against 0.4 C in a traditional sauna.
- : Wellness as a deaf or hard-of-hearing guest: the guide said alarms are almost always audible only; the ADA Standards cover visible alarms in public and common use areas, with an exception for existing facilities. The real risk is that a visible alarm works only in the space it serves. It also promised what venues would do, with no source, and described the ADA vaguely; it now gives the duty, no surcharge, the undue burden limit and DOJ's information line.
- : Does an infrared sauna burn calories: the guide had no who-should-check guidance and described sauna weight cutting with no warning. It now has both, with CDC's report of three college wrestlers who died on rapid dehydration programs, and an FDA recall for false calorie claims on an infrared sauna's labeling.
- : Contrast therapy: the guide said pairing heat and cold gets you heart and stress benefits; a 2026 systematic review found little evidence of heart or metabolic effects, and Harvard Health says cold plunges are not advisable after cardiovascular disease. It said a hot tub does not get you hot enough, where the trials it cited used hot water, and it misreported its one review (all 18 trials had a high risk of bias). It left out most of who should skip it and the risk of drowning from the gasp reflex.
- : Your first bathhouse or Korean spa: the guide told pregnant readers only to check with a doctor, where ACOG says it is best not to use saunas and hot tubs early in pregnancy and some spas say not to visit at all. It gave no rules on heart conditions, medicines or alcohol, nothing on scrubs and broken or sunburned skin, and quoted Island Spa's 15-minute limit where its safety page says 10.
- : Sauna, cold plunge and massage in pregnancy: the guide said to change massage positions later in pregnancy (NewYork-Presbyterian says no lying on the belly after the third month or on the back after the fourth), named no warning signs or when to call 911, said nothing about fever or a sauna before you knew you were pregnant, and left out falls and fainting. It said our maps show prenatal-friendly studios; they do not.
- : Sauna, steam and asthma: the guide said in eight places that warm, humid air is the comfortable choice; Asthma + Lung UK says hot, humid air can make asthma symptoms worse, and the CDC lists high humidity as a trigger. It answered a tight chest in a sauna with a lower bench (a tight chest is an attack sign: leave and get help), said to keep the reliever inhaler in the locker (keep it with you, but not in the hot room: its label warns above 120 F), called salt rooms unlikely to harm, and gave no attack signs or when to call 911. All are corrected.
- : About 100 pages and site sections said we only recommend what we would send a friend to, that we earn only on bookings we send, that guests pay on our platform, or that we may visit places. None of that is true today: we do not visit, vet or book places, nothing is bookable through Tendground, and no venue can pay to appear or rank. The lines are gone.
- : Are wellness retreats worth it: the guide said Spirit Rock's 7-night November retreat needs a prior weeklong retreat; Spirit Rock asks that only of commuters.
- : Wellness retreats on a budget: the guide sold intensive silent retreats as cheap depth with no word on who should wait and no crisis line, recommended saunas and cold plunges with no caution, and its price tiers came from no source. It now lists 13 centers' own prices, scholarships and refund rules, who the centers ask to wait, and 988 and 911.
- : Sauna or hot tub with a sunburn: the guide said the NHS, AAD and MedlinePlus tell you to stay out of the heat; they say to cool the skin and keep it out of the sun. It left out when to call 911 or 999, the CDC's rule against pools and hot tubs with an open wound, and any advice for children, and it gave a one-week wait that no source sets. All are corrected.
- : Are high-end wellness retreats worth it: the guide sent readers with burnout or grief to a retreat with no clinician line or crisis number, recommended a cold plunge and sauna routine with no caution, gave prices no resort publishes, and implied we had visited (you feel it the moment you arrive). It now lists what 12 resorts charge and include from their own sites, with 988 and 911.
- : Cupping therapy explained: the guide named no harms (burns, infections, scars) and warned only about the abdomen in pregnancy, where Cleveland Clinic says not to have cupping at all. It overstated the evidence five times, including a 2018 review it said found moderate evidence for neck and shoulder pain (that review rated its evidence low and did not cover the shoulder), and its prices and times came from no source.
- : Can you sweat it out: the caffeine row said sweat loss was not measured; a 2001 sauna study found at least 2.6 percent of a coffee dose in sweat, and that the heat slowed its breakdown.
- : Caffeine or pre-workout before a sauna: the guide had nothing on pregnancy, children and teens or what to do after too much caffeine, gave timing rules no source sets, and said no study had looked at caffeine in a sauna; a 2001 study did. It now covers the FDA warnings on DMAA in pre-workouts and Poison Help, and a table of the studies.
- : What to pack for a wellness retreat: the guide sent readers to saunas and cold plunges with no word on who should check first, mentioned altitude with no altitude illness guidance, and left out the medicine rules (original containers, declaring larger liquids to TSA, other countries' laws), sunscreen, repellent and ticks. Three lines read as if we had surveyed guests; they are reworded.
- : Sauna vs steam room: the guide told readers with asthma that the humid room is usually the comfortable one; Asthma + Lung UK says hot, humid air can make asthma symptoms worse. It said to ask before either room in pregnancy, where the sources it cites say to avoid both. It now covers burns from heaters and steam heads, other medicines that raise heat risk and a starting time for beginners, and its prices come from our price index.
- : Wellness after surgery: the blood clot warning named only one calf and gave no number to call; the NHS lists either leg, and chest pain, breathlessness or coughing up blood means calling 911. The guide gave no signs of a wound infection, and its waits for massage (a couple of weeks) and scar massage (six weeks or more) came from no source. It now follows Mayo Clinic, MedlinePlus, the CDC and NHS leaflets.
- : Winter retreats guide: an editing note from our 10-29 update, the words delete this paragraph, was published twice in place of two removed paragraphs. Both lines are gone.
- : Fall 2026 retreats, how far ahead: the guide gave booking windows for Sedona (three to five months) and the Texas Hill Country (two to four months) that no retreat publishes, said we curate and only recommend what we would recommend to a friend, and said you would pay in full on the platform. We do not vet or book retreats. It now gives what seven places listed for fall on Oct. 30, with their deposits and refund cutoffs, and who should check with a clinician before a sauna or cold plunge.
- : Are wellness retreats worth it: the guide named depression, anxiety, trauma and grief with no crisis line, and sent people running on empty to a retreat first. It now gives 988 and 911 first, says when to see a clinician instead, lists who the retreat centers ask to wait, and replaces unsourced price ranges with the retreats' own dated prices.
- : How much does a wellness retreat cost: every price band and tier on the guide was unsourced, and two lines were wrong: retreats do not expect an 8 to 12 or 10 to 15 percent tip (several say no tipping or include gratuities), and silent retreats are not free to 1,800 dollars. It priced medical detox and plant medicine retreats with no warning. It now lists 16 places' own prices with tax, service charges and refund terms, and the safety and legal points on alcohol withdrawal and psilocybin.
- : Acupuncture explained: the guide said electrical stimulation is contraindicated with a pacemaker (Mayo Clinic says it may interfere; ask your cardiologist), called the evidence for chemotherapy nausea strong (NCCIH says it is uncertain whether acupuncture adds to current drugs), gave session times and prices no clinic prints, and named no serious risks. It now does, condition by condition with the guidelines and Cochrane reviews, plus 988 and 911.
- : Home cold plunge setups: the guide recommended converting a chest freezer, in nine places; GE's freezer manual says to use the appliance only for its intended purpose, and we found no freezer maker that approves it, so we no longer recommend it. It said nothing about children and drowning, who should ask a doctor first, cold shock or time limits, and its prices and water change advice did not match the makers'. Four other guides that offered a freezer conversion were corrected too.
- : Berkshires retreats: the guide gave a price band no venue publishes, said spring is the best value and fall books months ahead (the venues publish winter midweek discounts only), and said you usually need a car (the two Lenox spas run transfers). It had no guidance on saunas, steam and cold plunges, ticks or meditation; it now has who should check with a doctor first, tick prevention, and 988 and 911. The title no longer says best.
- : Acupuncture vs massage: the sleep line left out the 2012 Cochrane review of 33 trials (too weak to support or refute acupuncture for insomnia), and the Medicare line said everyone giving the treatment needs an acupuncture degree; under the CMS rule a doctor can give it under state rules.
- : BookRetreats vs Retreat Guru, Retreat vs vacation and Yoga retreats for beginners: these guides said we only recommend what we would send a friend to, and that we earn only when a guest books and stays. Nothing on Tendground is bookable through us and we do not vet retreats; the lines are gone. Price ranges with no source on these and four other guides that link our cost guide were removed.
- : Best fall and winter retreats: the guide recommended long sauna sessions and a sauna and cold plunge loop with no caution. It now says who should check with a doctor first.
- : Wellness retreat FAQ: the page said it answered the questions people ask us before they book and called Tendground a curation marketplace; we take no bookings and list no retreats. It said the lift fades for almost everyone within two weeks, with no study; the vacation studies found it fading over about three to four weeks. It said sessions are optional and that rooms are often shared; several retreats require the full schedule and give single rooms as standard. It had no guidance on who should check with a clinician first, on medication, or a crisis line; it now does.
- : Fall and winter retreat guides: the winter guide said you can book a retreat online through Tendground and that we earn when a guest books; nothing is bookable through us. The fall guide said we curate and research the places it names and recommend only what we would recommend to a friend; it names no venue and we do not visit or vet retreats. Both gave booking deadlines with no source (fill by early autumn, book by late summer) and said rates fall after September; on two resorts' booking pages mid-October was the dearest date we sampled.
- : Site footer and three retreat guides: the footer said we may earn a commission when you book through a provider and that we only point you to what we would send a friend to. Nothing is bookable through us today, and the directory lists venues we have not visited, so the footer now says that no venue can pay to appear and that booking is planned. Three guides said the retreats page lists places we recommend or track; it lists none yet, and those lines are gone.
- : Home cold plunge and sauna costs: the guide said a chiller tub costs 2,000 to 5,000 dollars; the lowest chiller tubs on the makers' own sites listed from 5,590 dollars on sale. It said nobody quotes running costs, though Harvia, Sunlighten and Clearlight publish them, and that the mood benefits of cold plunging are real, which a 2025 trial did not find. It suggested a chest freezer conversion with no warning and gave no safety guidance at all; it now covers the makers' own warnings, GFCI testing, children and drowning, who should ask a doctor first, and recent recalls.
- : Acupuncture vs massage: the guide said massage clearly beats acupuncture for neck tightness; a 2024 Cochrane review found little or no difference between massage and placebo. It called the evidence for chemotherapy nausea genuinely strong; NCCIH says that research predates today's anti-nausea drugs. It left out that guidelines disagree on low back pain, Medicare's coverage rules, a recent heart attack or blood clot as reasons to ask before a massage, and a crisis line; it now has them.
- : Wellness on blood thinners: the guide said massage at moderate pressure is fine and that acupuncture is usually acceptable. Mayo Clinic says to talk with your healthcare team before a massage if you take blood-thinning medicine, and the NHS says acupuncture may not be safe for you if you take one, so the guide now says to ask your care team first.
- : Partners and Terms of Service: the partners page said that when you book a retreat or session through Tendground the provider pays us a commission, and that we list retreats we would send a friend to; the terms called Tendground a curated marketplace. Nothing on the site is bookable through us today and no retreat is listed, so both pages now say that booking is planned, not available.
- : Do wellness retreats work: the guide said the lift fades within about two weeks, with no study behind the figure; in the vacation studies it began to fade within days of returning to work and was gone within three to four weeks in several (Westman and Eden 1997, Westman and Etzion 2001). It said almost everyone comes home lifted; in one study 23 percent of 96 workers felt no effect. It called Tendground a curation marketplace, which we are not. It now gives 988 and 911, what retreat centers say about who should wait, and the known risks of intensive meditation.
- : Couples massage: the guide said unbooked vouchers are the ones that expire; federal law sets a five year minimum for most gift cards, and the cards that expire fast are free promotional cards. It said the two therapists do not work in sync; at least one resort spa sells a synchronized couples massage. It linked the wrong page for massage prices, and it said nothing about pregnancy or about who should check with a doctor first (a recent heart attack or blood clot, a bleeding disorder, blood thinners); it now does.
- : Santa Fe and New Mexico retreats: the guide said we only recommend what we would send a friend to; we do not visit or vet venues, and the line is gone. It put Truth or Consequences at about 4,600 feet (it is about 4,296), called Santa Fe's airport limited and said the area is not reachable any other way (it has daily direct flights, a commuter train and shuttles), and gave a price band and a humidity figure with no source. It recommended outdoor hot springs in the monsoon with no word on lightning or flash floods; it now gives the National Weather Service's warnings and the springs' own soaking rules.
- : Your first cryotherapy session: the subtitle said minus 200 degrees with no unit and the description near minus 200F; chambers run at about minus 110 to minus 140 degrees C. It called head-out cabins whole-body cryotherapy; they are partial-body cryosaunas cooled with nitrogen vapor, which carries a risk of asphyxia, so keep your head out and never use one alone. Its list of who should not use cryotherapy was incomplete, and it said a cold plunge is the stronger cold stimulus, which a head-to-head study did not find.
- : Is a massage chair worth it: the guide said pregnancy, pacemakers, osteoporosis, blood clots and acute pain mean asking a doctor first; one maker's manual says people in those groups should not use its chair at all. It said a 4,000 dollar chair costs about forty massages; at our 120 dollar median it is about 33. Its price tiers had no source and are replaced by one maker's dated prices.
- : Meditation vs breathwork: the guide recommended breathwork for anxiety spikes with no crisis line and no safety guidance; it now gives 988 and 911, says to see a professional when anxiety keeps coming back, and warns that fast breathing can trigger seizures in people with seizure disorders and must never be done in or near water or while driving.
- : How to build a sauna and cold plunge habit: the guide gave no guidance on who should check with a clinician first; it now covers heart conditions, pregnancy, medication, cold shock and alcohol. It said most people quit within a month and that a chiller is half of why people keep going, with no source for either; both lines are gone.
- : How to build a weekly recovery routine: the guide said to finish a sauna 60 to 90 minutes before bed; the studies of warm baths point to one to two hours. It said a couple of sauna sessions a week captures most of the benefit; in the Finnish cohort the clearest link was at four to seven a week. Its membership arithmetic contradicted our own price index, and it had no guidance on who should check with a clinician first; both are fixed.
- : How to try wellness without a membership: the guide said venues do not advertise day passes and other no-commitment options; the 23 venues on our day pass page publish theirs. It said intro offers are priced below cost, with no source, and that the chargeback deadline runs from the service date; the CFPB says to write to your card company within 60 days after the charge appeared on your statement.
- : Your first Pilates class: the guide told readers who are pregnant, injured or recovering from surgery only to tell the instructor, and did not mention osteoporosis; it now says to check with a clinician first and gives ACOG's and the Bone Health and Osteoporosis Foundation's guidance.
- : Is assisted stretching worth it: the guide said nothing about acute injuries or low bone density; it now says that StretchLab itself turns away acute injuries and that its staff are not physical therapists, and adds a 2016 review finding that the extra range from one session typically lasted under 30 minutes.
- : How far ahead to book a wellness retreat: the guide said to book a small retreat 3 to 6 months ahead and a destination name 6 to 9 months out. None of the 15 retreat centers and resorts we read publishes such a rule, so the guide now shows what they do publish: how far ahead their calendars run, deposits, balance dates and refund cutoffs. It said most retreats ask a 20 to 50 percent deposit; deposits run from a card guarantee to the full price. It said guests pay through our platform and offered to tell readers when to book; we take no bookings and give no individual advice, and those lines are gone.
- : How to choose a wellness retreat: the checklist said three to five hours of programming a day is typical and eight is a bootcamp; every schedule we read runs about six to ten hours. It advised wiring the deposit; the FTC says wiring money is like sending cash, while a credit card charge can be disputed, so it now says to pay by card. It called travel insurance not optional and tips expected; both depend on the retreat. It gave transfer, room and deposit figures with no source, and said nothing about who should talk to a doctor or therapist before booking, or about heat, cold, breathwork and fasting; it now does.
- : Wellness retreats for anxiety and burnout: the guide named thoughts of self-harm but gave no crisis line; it now gives 988 and 911 first. It called healing and trauma-informed retreats the closest fit when anxiety is the main reason to go; NIMH advises talking to a professional, and the programs that do emotional work screen for anxiety disorders, so the guide now says to see a doctor or licensed therapist first. It now also quotes what the retreat centers say about who should wait, and says never to stop prescribed medication. It said you could browse retreats on Tendground; none are listed yet. It called forest bathing one of the best-supported ways to calm a stressed system; a review rated most of that evidence low or critically low, and the line is gone.
- : Burnout retreats in the US: the guide advised silent or near-silent retreats for people at the edge. The Insight Meditation Society says a silent retreat may not be appropriate with significant depression or anxiety, so the guide now says to read a center's health guidance first and to start with a doctor or therapist when low mood or anxiety gets in the way of daily life. The same day it was merged into the guide to retreats for anxiety and burnout, which covers the same ground.
- : Pacific Northwest wellness retreats: the guide said we run a marketplace, see booking patterns, work with operators and add notes after we visit. None of that is true: we have no retreat listings and do not visit venues. Those lines are gone, and the guide now lists what nine venues publish on their own sites. It also left out wildfire smoke, cold water and tsunami safety, said road closures were rare and brief, said Sedona sleep needs care at altitude (it sits at about 4,200 feet, below the 8,000 feet where the CDC says altitude illness becomes a risk), and treated the hot springs as open all year; all are corrected.
- : When to go on a wellness retreat: the guide called late April to early June and September to early November the cheaper shoulder seasons, at 10 to 30 percent below peak. Rancho La Puerta charges its High Season rate in exactly those weeks, and at two Arizona resorts mid-October was the most expensive date we priced, so the guide now shows each resort's own prices by date. It said a three-night retreat with two flight days leaves one retreat day; it leaves two. It also now covers the desert monsoon, afternoon mountain lightning and when to see a clinician for burnout.
- : Meditation apps compared: the guide called the Happier Meditation app by its old name, Ten Percent Happier. It said the apps are not what research studied; Headspace, Calm and others have their own randomized trials, which the guide now summarizes. It said apps are excellent at habit, while most users stop within weeks. It told sleep seekers to stop paying for a meditation app and use Calm, but most of Calm's library needs a subscription. It now gives each app's own price, the evidence on sleep, and when an app is not enough, including 988.
- : Berkshires wellness retreats: the guide said western Massachusetts has been a wellness destination longer than almost anywhere in the country, with no source; that line is gone.
- : Do you tip at a spa: the guide said spa gift cards usually do not cover the tip. A Massage Envy gift card can pay it, under Massage Envy's own gift card policy, so the answer now depends on the card. It said to tip 15 to 20 percent; the two chains that publish a number, Burke Williams and Heyday, both say 20, and the guide now says about 20 percent. It presented Elements Massage's line that gratuity is not included as a general pricing rule; the line is about its gift cards. A sentence saying tipping is the most common question front desks get had no source and is gone.
- : Korean spa etiquette: the guide told readers to bring flip-flops or sandals. Most of the Korean spas we checked are barefoot inside, and King Spa Dallas, King Spa Virginia, Island Spa and Spa Castle do not allow your own footwear, so it now says to check the footwear rule. Its table said Olympus Spa did not state rules on nudity, phones or shoes; Olympus publishes all three. A robe and towel at check-in came from a customer review, not the spa. Lines saying first-timers stop feeling self-conscious by the second hour had no source and are gone.
- : Canyon Ranch vs Miraval: the comparison gave Canyon Ranch's price as offers from $1,000 to $1,500 a night. That range covered only the Tucson and Lenox offers. The page now gives the Stay Your Way starting price ($1,250 per person a night in Tucson and Lenox, $1,325 in Austin), notes that Lenox's All You Can Spa starts at $1,800, and lists taxes, alcohol and retail as billed on top.
- : City directory pages said we had not visited all the venues listed, which could suggest we had visited some. We do not visit venues; the pages now say so.
- : Civana vs Miraval: the comparison said Civana showed no day-pass price; its booking page listed $349 with one treatment and $549 with two. It said Miraval's roster meant you never had to plan, but Miraval says planning is part of the stay, and many activities and spa services must be booked before arrival. It placed Miraval Arizona in the Catalina Foothills, a separate community to the south; Miraval says north of Tucson, in the foothills of the Santa Catalina Mountains. Claims that six or seven nights is where behavior change starts, that two Civana trips beat one Miraval trip, and that a weekly sauna and cold plunge habit beats any trip had no study behind them and were removed. The page now shows what each price includes, from both resorts' own sites.
- : Silent meditation retreats in the US: the guide said nothing about who should not attend, although several of the centers it named publish exactly that; it now quotes them. It described visits and interviews we did not make; those lines are gone. It said Dhamma Siri was the closest Goenka center to Austin and filled by lottery: Dhamma Sukha in New Ulm is closer, and Dhamma Siri opens applications at a set time. It also said Goenka centers were in 17 states (Dhamma.org lists 14 centers in 10), described a three-month fall retreat at IMS (2026's long retreat was two months), priced a week at IMS or Spirit Rock at $700 to $1,400 (seven nights cost $330 to $2,430 at IMS and $1,120 to $4,270 at Spirit Rock), called Cloud Mountain secular (it is a Buddhist center), and said 30 to 60 days non-refundable was standard (most centers checked stop refunds two to four weeks out). Its secular trauma-informed weeks at $1,500 to $3,500, its Sedona and Hill Country claims and its advice to stay in a cold plunge until the urge to leave passes had no source and were removed. Our bipolar disorder guide said this guide told readers with a bipolar history to consult a clinician; it never did, and that sentence now describes what the guide covers.
- : Reformer Pilates vs Lagree: the comparison said a Lagree class costs at or above the reformer end of the range. At seven Megaformer studios a single class cost $35 to $44, inside Club Pilates' published $25 to $52, and the page now says so. The image description on our Lagree class guide called the pictured machine a Megaformer; it has shoulder rests, which a Megaformer does not, and the description now says what it shows.
- : US hot springs: what to know before you go: the guide said to test the water with a hand and to soak 10 to 20 minutes, and framed the rule to keep your head out of the water as applying to untreated springs. No US agency endorses a hand test or sets a soak time; the CPSC advises an accurate thermometer, and the CDC says to keep your head above water in every hot spring, which includes resort pools that are not chlorinated. The guide also called spring water hotter than any sauna (the fair comparison is a hot tub) and listed Ten Thousand Waves, which uses well water, as a hot spring. It now says so, and adds a section on hot springs with kids.
- : Hot springs while pregnant: the guide said developed resorts control pool temperature, which made the 100°F limit possible. Many resort pools run above 100°F, so the guide now says to ask for the coolest pool and check it with a thermometer.
- : Sauna, hot tubs and sperm count: the guide called the effect of one sauna session negligible and very unlikely to matter. In a small 1984 study, a single 20-minute sauna at 85°C lowered sperm numbers within a week, and they took about five weeks to return to normal. The guide now says so.
- : Sauna or hot tub while trying to conceive: the guide said to skip saunas and hot tubs from ovulation until your period or a negative test. An early negative is unreliable: the FDA says 10 to 20 of every 100 pregnant women do not detect the pregnancy even on the first day of a missed period, so the guide now says until your period starts. It also called the absolute risks small; that holds for neural tube defects, but miscarriage is common, and the guide now says so.
- : Canyon Ranch vs Miraval: the comparison said the Berkshires has been a wellness destination longer than almost anywhere in the country, with no source; that line is gone. The page now also notes that Tucson and the Austin area have a resort of each brand, and its tipping row quotes Canyon Ranch's own no-tipping policy.
- : Breathwork retreats explained: the guide described the Wim Hof ice bath as two to three minutes in 38°F water and said to hold your breath for as long as you can. The Wim Hof Method says to hold only until you feel the urge to breathe again and calls cold exposure gradual and optional, and Cleveland Clinic advises beginners to start at 50 to 59°F for a minute or two. The guide also left out the method's rule never to practice in water, in the shower or while driving; it now opens with it, with each method's own list of who should not take part. A description attributed to "most people" had no source and was removed.
- : Yoga class vs a yoga app: the guide said no app can see your form and that a class keeps you safe. Some apps say they check your pose through the phone camera, live online classes let a teacher watch you, and a review of nine studies put the incidence of adverse events during a yoga class at 22.7%. The guide now says so and gives studios' and apps' own prices.
- : Yoga apps compared: the guide still used the name Alo Moves and called it a mid-priced subscription; it became ALO Wellness Club in 2025 and has been free with an account since December 2025. It called Glo mid-priced, though Glo costs the most of the five, and said the paid apps have free tiers; Down Dog, Glo and Peloton offer free trials only.
- : Barre vs reformer Pilates: the guide said no exercise changes muscle shape, that barre is bodyweight work in standing positions and that barre is easier to find. Resistance training can change a muscle's shape, barre classes include floor and mat work, and Club Pilates had 1,414 studios at the end of 2025 against 625 for Pure Barre. The guide's price ranges had no source; it now gives each studio's published prices.
- : "Sources checked" lines: when the line launched earlier the same day, the count on 11 pages was too high, by 1 to 9 statements. It included statements those pages do not make (claims we had removed or reworded, and source passages we had read only as background) and counted a few statements twice. Each count now includes only statements on the page, each matched to its source's words.
- : Hotel spa vs a wellness retreat: the guide said both cost $2,000 to $5,000 a week, that a three- to five-night retreat commonly runs $1,500 to $3,500, and that a retreat's bundle rarely covers airport transfers or one-to-one bodywork. None of this had a source, and the venues' own pages show otherwise: published prices run from $99 a night plus housing at Kripalu to $5,565 for three nights at Cal-a-Vie, whose packages include airport transfers and massages. The guide now gives each venue's own figures.
- : Feeling faint in a sauna: the guide listed sweating that seems to stop among the warning signs of fainting. Hot skin that has stopped sweating can be a sign of heatstroke, and the guide now lists it among the reasons to call 911. It also said almost every serious sauna injury not linked to alcohol came from standing up and falling; at an Austrian trauma centre, slips and falls caused 57.5% of sauna injuries and dizziness or fainting 30%, and the guide now gives those figures. Unsourced lines about bench temperatures and staff at public studios were removed.
- : Should you eat before a sauna or cold plunge: the guide said to give a full meal ninety minutes to two hours before intense heat or cold. No health body we checked sets a wait after eating, so the guide no longer gives one.
- : Hudson Valley and Catskills retreats: the guide said to expect $300 to $600 per person per night, with no source. It now gives each of five retreats' own published price.
- : Does an infrared sauna burn calories: the article said the 600-calorie figure came from an old letter about boxers cutting weight. It traces to a 1981 letter to the editor in JAMA that mentions a marathon runner, not boxers, and that a reply in JAMA called highly doubtful in 1982; the article now names both. It also compared a session's energy use with a slow walk. The walking comparisons in the research describe the heart's workload; the measured extra energy use is smaller than a very slow stroll.
- : Smartwatches and rings in the sauna: the guide said WHOOP had published nothing on saunas. WHOOP's support page recommends avoiding temperatures outside 15 to 140°F, and the guide now quotes it.
- : Blood pressure medication guide: said hydration was not optional. It now adds that this is within any fluid limit your doctor has set, because the hydrochlorothiazide label notes that some people with swelling are treated with water restriction in hot weather.
- : POTS guide: seven sentences corrected or re-sourced. The list of triggers now follows the Heart Rhythm Society (2015) and Canadian Cardiovascular Society (2020) statements and a 2026 paper in JAMA, a cool shower became a lukewarm one, and tips without a source were removed.
- : BookRetreats vs Retreat Guru: said both platforms hand refunds back to the retreat provider. BookRetreats gives 72 hours to cancel for a full refund and handles refunds itself.
- : ClassPass vs Mindbody: four corrections. An unsupported "half the market" claim was removed, Mindbody's dynamic pricing was added, the guide now says ClassPass credits roll over on most plans, and it notes that both companies are owned by Playlist.
- : Las Vegas guide: Frost Fit no longer lists a cold plunge on its own site, and its address is Suite 103.
- : ADHD stimulants guide: said hyperthermia appears in the labels only in the overdose sections. It is also listed as a sign of serotonin syndrome, and methylphenidate labels report very high fever after the drug reached the market. The guide also gave Concerta's peak as 5 to 9 hours; the label's mean time to peak is 6 to 10 hours.
- : Antidepressants guide: said the Wellbutrin XL label does not mention a high body temperature. The label lists fever and hot flashes. A sentence about seizures implied stopping bupropion; the label's point is that heavy alcohol use raises seizure risk and that stopping alcohol abruptly is a reason not to take it.
- : Blood thinners guide: said heat is fine for the drug, which had no source; the labels raise no heat warning, and the guide now says only that. A line about head injuries now quotes the warfarin Medication Guide.
- : GLP-1 medication guide: said the drugs suppress thirst, which had no source. The labels' point is that nausea, vomiting and diarrhea may cause a loss of fluids, and the guide now says that.
- : Ice bath guide: a claim that cold water raises norepinephrine by 200 to 300% now gives the hour-long 57°F study it comes from and that study's measured rise.
- : Washington DC guide: corrected the number of water cold plunges in the District itself. One is in the District, and four more are just outside it.
- : Sauna for older adults guide: the Finnish study it cited followed middle-aged men, and the guide now says so. Cold plunge after a workout guide: corrected two study descriptions; Fyfe and colleagues (2019) found no loss of strength, and the placebo trial is Broatch and colleagues (2014).
- : Medication heat-warning label index: the Neurontin (gabapentin) sweating entry was marked as a side effect. The label lists sweating only among symptoms reported after the drug is stopped, so it is now marked as a withdrawal symptom, with the label's framing sentence quoted.
- : Chicago guide and directory: removed Chicago CryoSpa. Its website no longer loads and review sites list the location as closed.
- : City guides: price ranges and plunge temperatures that were not tied to any venue were replaced with what each venue publishes on its own site, or removed where no venue publishes a price.
- : City guides: removed claims nothing on the page supported, such as rankings against other cities, neighborhoods none of the listed venues are in, and bathhouse traditions in guides that list no bathhouse. Corrected venue details that the venues' own sites contradict, including an address, a women-only spa, and services one location does not offer.
- : Removed nine listings: two studios whose own sites say they are temporarily closed, two locations their brands no longer list, a float-tank maker whose site offers no sessions, an in-home sauna rental service that is not a place you visit, and three private adult clubs that were listed as ordinary saunas.
- : Statistics page: said the dataset refreshes weekly. It does not; the page now points to the date it was last rebuilt.
- : Removed an article written as a first-person account of five nights at a Texas Hill Country retreat, with prices and staff details. Nobody from Tendground stayed there. It was not true and should never have been published. Its address now redirects to our regional guide.
- : Removed sentences in several retreat guides that said or implied we had visited, stayed at or vetted the properties. We research programs from what they publish; we have not visited them.
- : Corrected the publish date on 107 articles. Some showed dates earlier than the day the page first went live, including dates before this site existed. Each now shows the day it was first published, and an Updated date appears only after a substantial rewrite, not after a wording change.
- : Medication and heat checklist: the stimulants row said they raise core temperature. Their labels warn about heart rate and blood pressure, and that is what the row now says.
- : Minoxidil guide: removed a dose range. Our medication guides give no dosing.
- : Blood thinners guide: St John's wort was grouped with supplements that raise bleeding risk. With warfarin and Xarelto it works the other way (it can weaken the drug), as their labels say. Corrected.
- : ADHD stimulants guide: a Vyvanse timing figure mixed a children's fasting value with an adult value after a meal. Corrected to the label's adult figures.
- : Directory and city guides: some cryotherapy businesses (a dry cold-air chamber) were listed as cold plunges (water immersion). They are now listed under cryotherapy only, unless the venue's own website shows a plunge. Houston no longer has enough verified cold plunges for its own page.
- : Withdrew the US Recovery Index. Our venue counts are capped per search, so a per-person ranking mostly reflected city size rather than anything about recovery culture.
- : Removed a closed business (The Cove, Denver) and a listing that was not a business at all, and stopped linking eight venue websites that no longer load.
- : ADHD stimulants guide: said stimulants blunt thirst, which their labels do not say. Removed. The medication hub said stimulants raise core temperature; corrected to what the labels and CDC say.
- : Red Mountain Resort in Ivins, Utah has closed. Two articles presented it as bookable; both were corrected.
- : Removed retreat listings from an article that described facilitators who do not exist and linked to retreats that did not exist.
