Vagina steaming

I suppose this […] "vaginal" steam bath is just something that we nasty, allopathic […] doctors just don't understand. To us, it's just shooting a bunch of steam up a woman's nether regions. To the woo-meisters, though, it’s not just steam that's being forced to go places where usually only spouses, lovers, or gynecologists go. Oh, no. It’s super special, extra powerful herbal detox steam, which means that it has super duper magical powers.

Vagina steaming is a hot newly revived alternative medicine practice in which a person with a vagina squats over steaming water. The practice is also called vaginal steaming, v-steaming, vaginal steam baths, yoni steaming, chai yok (차욕), or bajos.

Vagina steaming supporters, who include noted pseudoscience promoters NaturalNews and Gwyneth Paltrow, claim that it has numerous benefits. Vagina steaming is supposed to "cleanse" the vagina, increase fertility, treat bad periods, and remove "toxins". There is no scientific evidence for any of these claims. Fully 14 of the 16 medical professionals who have commented on the practice say that vagina steaming is ineffective, or possibly harmful. In short, it is patent bullshit.

However, vagina steaming may genuinely upset that little man in the boat.

History
It has sometimes been reported than an unspecified 8th century CE Sanskrit document described sitting over a pot of boiling onions as an abortion method — but no one ever says which document, so it could be BS. There is evidence of tradition use of vagina steaming in a few locales around the world (Tete, Mozambique; KwaZulu-Natal, South Africa; Yogyakarta, Indonesia; Chonburi, Thailand; and Belize),  but this has not been how the practice has been promoted in the West.

More definitively, The New York Medical Journal in 1897 reported the experimental use of steam on the uterus after an abortion, though unsurprisingly this is known to cause severe burns to the delicate genital area. This technique was being used in 20th century New York City.

Why is vagina steaming a thing nowadays? Blame celebrities and clickbait.

In the West, vagina steaming was not popular until the late 2000s. However, it had a following in the alternative medicine community, especially "traditional" Korean and Mesoamerican practitioners, who offered vaginal steam baths (then often called chai-yok or bajos). These spas played up vagina steaming as an ancient and exotic practice and customers trickled in. Eventually, nontraditional spas began offering vagina steaming (likely because boiling water and letting customers pay to sit over it is lucrative).

Niki Han Schwarz
Vagina steaming hit the limelight in December 2010, when Niki Han Schwarz (owner of a traditional Korean spa) persuaded journalists to boost her fame report on her claim that vagina steaming helped her become fertile. This started a (short-lived) period where journalists (usually female) got vaginally steamed and wrote about the experience. In turn, this briefly increased vagina steaming's broader popularity.

After the hubbub died, vagina steaming quietly established a growing niche in spas, especially alternative-medicine spas.

Tia & Tamera Mowry
In 2013, twin actresses Tia and Tamera Mowry got vaginally steamed and claimed it reduces menstrual cramps, prevents yeast infections, and treats infertility. This again sparked a burst of popularity. This time, vagina steaming was more widespread, allowing more people to actually do it &mdash; and write about it. As a result, vagina steaming's broader popularity continued to exist (at low levels) until 2015.

Gwyneth Paltrow
The real golden ticket here is the Mugworth [sic] V-Steam: You sit on what is essentially a mini-throne, and a combination of infrared and mugwort steam cleanses your uterus, et al. It is an energetic release — not just a steam douche — that balances female hormone levels. If you’re in LA, you have to do it.

In January 2015, Gwyneth Paltrow (a fashion guru and alternative medicine promoter) got a vaginal steam bath and preached its virtues (see quote). Gwyneth defended vagina steaming against the torrent of Internet ridicule by arguing that vagina steaming "is a thousands-of-years-old practice in Korean spas". Eight months later, Paltrow changed her story and claimed that the piece on vagina steaming "actually came from her editorial director, Elise Loehnen". Right.

On the greatest scale yet, another phase of journalists got steamed and wrote about it. Vagina steaming underwent a large, apparently permanent jump in popularity, maintaining almost Paltrow-era popularity 15 months later.

What is it?


Vagina steaming is cheap and simple, which probably explains why spas delight in charging their customers for the procedure. It goes as follows:


 * 1) A pot is filled with:
 * 2) Water (necessary)
 * 3) Any desired plants (optional)
 * 4) The pot is heated until the water starts steaming.
 * 5) The pot is placed under/into a seat that allows steam to rise into the vagina, such as a toilet.
 * 6) A person with a vagina then:
 * 7) Removes any clothing covering the vagina (necessary)
 * 8) Covers themselves with a blanket to prevent the steam from escaping (optional)
 * 9) Widens their legs to increase steam intake (optional)
 * 10) The "patient" then squats on the chair for 20 minutes to 1 hour.

Vagina steaming supporters warn against steaming while pregnant, immediately after delivery, or if the vagina has an infection. Supporters also advise that a medical professional be consulted before the steaming. This is likely a case of the salon planning to blame the victim should anything go wrong, rather than an expectation that the client will actually see a medical professional.

Scientific consensus
When I first read the articles about V-jay steaming, I wasn’t sure if they were discussing a feel-good technique, a novel treatment for the crabs, or a new venue for cooking your dumplings. But after managing to suspend my disbelief, I finally gathered that this is pure kitsch — a fad touted by uninformed celebs. I checked the medical literature as thoroughly as I could and found no credible evidence of any GYN health benefit from steaming one's junk. Positive health claims appear nothing more than anecdotal. Most medical professionals who are authorities on the matter (OBGYNs and MDs) are very much skeptical of the benefits of vagina steaming due to the lack of empirical evidence to support it. Currently, the tally stands at 14 (93.3%) in opposition and 1 (6.7%) in favor:

In opposition
OBGYNs:
 * 1) Dr. Manny Alvarez, Chairman of the Department of Obstetrics and Gynecology and Reproductive Science at Hackensack University Medical Center: "There is absolutely no way [vagina steaming] has any significant health benefit."
 * 2) Dr. Pari Ghodsi, Group Practitioner at Northlake Obstetrics & Gynecology, P.A.: "V-Steam, although a catchy name, makes no sense and is an overall bad idea."
 * 3) Dr. Draion Burch, clinical assistant professor in the Department of Obstetrics, Gynecology, and Reproductive Sciences at the University of Pittsburgh School of Medicine: "There's no scientific evidence that shows it works."
 * 4) Dr. Suzanne Gilberg-Lenz, OBGYN at Women's Care of Beverly Hills Medical Group: "Most of these kinds of treatments are not put through intensive clinical trials, so it becomes challenging to evaluate the actual impact they have."
 * 5) Dr. Camilo Gonima, OBGYN at the Institute for Women's Health: "Other than any possible involvement [that] stress might have on these issues, I don't see any basis for any significant effects on fertility or menstrual cycles. … [I] would emphasize that this should be entirely external, and I'd be cautious about safety to avoid the risk of scalding."
 * 6) Dr. Vicken Sahakian, OBGYN and medical director of Pacific Fertility Center in Los Angeles: "It sounds like voodoo medicine that sometimes works."
 * 7) Dr. Jennifer Gunter, widely-certified OBGYN: "Steam is probably not good for your vagina. Herbal steam is no better and quite possibly worse. It is most definitely more expensive."
 * 8) Dr. Mary Minkin, MD, OBGYN at Obstetrics Gynecology & Menopause Physicians, P.C. and clinical professor at the Yale University School of Medicine: "It's complete bull."
 * 9) Dr. Jennifer Ashton, OBGYN: "There is zero medical evidence to support the need for or benefits of vaginal steaming. The physiology of the vagina is such that it is constantly cleaning itself and doesn't need extra help. … Just make sure to avoid thermal burns from hot steam."
 * 10) Dr. Hilda Hutcherson, OBGYN at Columbia University Medical Center: "It probably feels good because the heat increases blood flow to the whole vaginal area, including the clitoris, which could turn some women on. But if you got too close to the steam, you could end up with second degree burns down there."
 * 11) Dr. Taraneh Shirazian, OBGYN at Mount Sinai Hospital in New York City.
 * 12) Dr. Katherine Thurer, gynecologist at the Raby Institute for Integrative Medicine at Northwestern University: "I could imagine one could have an allergic reaction to an herb or get burned." That said, she also writes: "Healthy vaginal tissue is used as an effective vehicle for the administration of medications like antibiotics, antifungal creams and hormones, so I suspect the herbs in the steam can be easily absorbed this way, too."

MDs:
 * 1) Dr. Siri Chand Kaur Khalsa, MD, One Medical Group and "Integrative medicine" practicioner: "The premise that the body needs spa treatments to remove toxins has no clear basis in human biology. … Regarding Vaginal Steaming’s proposed health benefits, the vagina has extensive blood flow and mucous membranes, so it absorbs medications easily, but there is no scientific evidence to support the effectiveness of absorbing herbs vaginally."
 * 2) Dr. David Gorski MD, PhD, FACS, Professor of Surgery at Wayne State University School of Medicine and surgical oncologist at the Barbara Ann Karmanos Cancer Institute specializing in breast cancer surgery: "I suppose this whole 'perineal' or 'vaginal' steam bath is just something that we nasty, allopathic 'Western' doctors just don't understand. To us, it’s just shooting a bunch of steam up a woman’s nether regions."

Non-MDs:
 * 1) Timothy Caulfield, Professor in the Faculty of Law and the School of Public Health at the University of Alberta, and author of Is Gwyneth Paltrow Wrong About Everything?: : "Paltrow is the perfect symbol of popular culture in our world right now. […] I think she should be held to a standard and that standard should be science. […] The claims made for [vagina steaming] are wrong and it could even be harmful[.] […] You shouldn’t monkey with the bacterial flora down there."
 * 2) Nicholas LeRoy, Doctor of Chiropractic, founder of Chicago-based Illinois Center for Progressive Health: "HPV can live on the surfaces of objects for long periods of time."

In favor
OBGYNs:
 * 1) Dr. Lissa Rankin, MD, OBGYN, "mind-body medicine physician", founder of the Whole Health Medicine Institute, author of Mind Over Medicine: Scientific Proof That You Can Heal Yourself: "There's no scientific evidence to support or reject the claims made by advocates of vaginal steam baths, so the truth of the matter is that we just don't know whether they offer any health benefit. But I'm not one to knock ancient Eastern health care practices, so who knows? I'm a big fan of checking in with your gut (and your lady bits!) What does your body tell you? […] [I]f the wisdom of your body speaks to you and says, "YES! This is the answer for me," pay attention."

PhD's:
 * 1) Dr. Lisa S. Lawless, PhD, psychotherapist and CEO of Holistic Wisdom, Inc.: "Vaginal steaming in Chinese medicine is used to relieve stagnation and coldness in the body, and in Eastern medicine in general it is used to dilate the blood vessels, increase blood circulation, provide oxygenation and relax the pelvic floor muscles. Other ways it improves health depends on the herbs that are used and the healing properties each herb brings to the table."

Non-MDs:
 * 1) Rosita Arvigo, Doctor of "Vaginal or yoni steam baths are an old, respected treatment for women used by Maya midwives and traditional healers in Central and South America. The practice is mentioned in early chronicles of Spanish friars who took time to record the healing practices of the Maya and Aztec. Bajos (ba-hoes) as they are called in Spanish, are a common and effective treatment for many female complaints, especially those of a serious or chronic nature."
 * 2) Isa Herrera, & CSCS (both non-doctoral positions), and employee of Renew Therapy (which offers vagina steaming): ''"[The] steam works wonders on hemorrhoids [and] for women who are trying to have a baby either naturally or with assistive fertility therapy. … It is a wonderful way to nurture the soul, spirit and body all at the same time."

Impacts
An easy guide to the claimed impacts of vagina steaming:


 * Beneficial:
 * Adds good plants to the vagina: No. No significant amount of plant matter gets into the vagina. Most of the plants have no proven positive health effects, and possible negative ones.
 * Cleanses: A little yes, mostly no.
 * Cleans the vagina: No. The vagina self-cleans. Douching doesn't work and is harmful.
 * Cleans the uterus: No. Almost no steam will enter the uterus.
 * Reduces odor: Yes. Odor can be drowned out with the smell of something else. However, odor is not harmful, is normal, and can help diagnosis.
 * Removes toxins: No. The alleged removal of vaguely-defined "toxins" is an unscientific claim by definition.
 * Helps irregular periods: Probably not. Vagina steaming will not solve any of the hormonal imbalances/pituitary tumors that cause irregular periods.
 * Treats abnormal growths: No. You can't steam away cancer.
 * Prevents vaginal infections: Hell no.
 * Balances hormones: No. The vagina does not regulate hormones — and even if they did, steam would not "balance" them.
 * Aids fertility: No.
 * Niki Han Schwarz did it!: No. This argument is anecdotal, untested, and self-interested information isn't acceptable.
 * Increases circulation: Maybe, but there are currently no credible studies that support this idea — and it is unlikely to be true since anyone with half a brain already knows that burning the vagina is bad, and many better alternatives exist.
 * Great for testicles too!: Now cis men and trans women can also enjoy the benefits of getting steamed! Nope. Warmer balls are less fertile.
 * Aids relaxation: Sure. Sitting somewhere warm and not doing anything for an hour is probably pretty nice.
 * Causes arousal: Yes. This probably explains everything reported on the "beneficial" side.


 * Harmful:
 * Causes infections: Possible, especially if done wrong. Shooting water into the vagina upsets its naturally acidic pH, hurts good bacteria, and makes infection more likely.
 * Causes steam burns: Possible, especially if done wrong. Steam is as hot as boiling water, and therefore is far more likely to cause burns.
 * Causes vaginal irritation: Possible, especially if done incorrectly. Shooting water into any organ hurts it, and allergic reactions to the plants used aren't impossible.
 * Causes complications during pregnancy: Likely, especially if done wrong. Putting boiling water next to a womb which contains a developing baby is probably not a great idea.
 * Causes contraction of the purse: Yes, even if done right.

Claimed benefits
Vaginal Steaming: Just a Bunch of Hot Air? Before discussing any specific claims, it's useful to remember a couple of general ideas:

First, no medical studies have been done on the efficacy of vagina steaming, which makes all evidence for these claims anecdotal at best. Further, almost all of reports of the effects of vagina steaming are produced by practitioners of it, which leads to an obvious conflict of interests and may lead to false, exaggerated, and/or selective reporting.

Second, many of the healing effects claimed to be the result of vagina steaming are within the bounds of a regression to the mean, where the ailment was likely to go away even without vagina steaming. Whether a regression to the mean occurred is impossible to tell without comparison to a placebo in a controlled trial, of which none have occurred. Given how dubious the benefits are and how easily it can do harm, a formal investigation into vaginal steaming is unlikely to happen.

Adds good plants to the vagina
Most vagina steaming claims are based on the transfer of good plants into the vagina via steam.

When practitioners add plants to boiling water and let it steam, it is improbable that any significant amount of the plant rises with the steam, much less enters the vagina, the bloodstream, or the skin. If the plant is truly effective, why not increase the concentration and use it topically (smear it on) or insert it directly? To quote Dr. Siri Khalsa:

The most commonly used herbs are mugwort, oregano, rosemary, basil, calendula, and marshmallow root. Unsurprisingly, most of the plants used don't do what is commonly claimed (see the main articles for more):


 * Basil (Ocimum basilicum) is claimed to be antibacterial and spiritually cleansing. In vitro (test tube) studies have shown basil's antibacterial properties; however, no clinical studies have been conducted, so we don't know how well it works for humans or whether 'vagina steaming' is an effective method for applying it. No reputable journals have published on basil's spiritually cleansing properties yet, so we'll just have to wait for confirmation on that one.


 * Chamomile (Asteraceae spp.) is claimed to be soothing, anti-inflammatory, antibacterial, antiviral, and antiparasitic. In vitro (test tube) studies have shown that chamomile is antibacterial and antiviral; however, in vitro studies cannot necessarily be applied to humans. None of the other claims appear to have scientific merit.


 * Horsetail (Equisetum spp.) is claimed to flush bacteria out of the bladder. There's no evidence that horsetail is antibiotic. There is evidence that horsetail, especially when improperly used, contains potentially toxic chemicals!


 * Mugwort (Artemisia vulgaris) is claimed to be ancient medicine, contain antibiotics and antifungal agents,  stimulate production of hormones to maintain uterine health,  prevent cancer,  prevent ulcers,  stimulate a period,  ease mental discomfort, reduce the impacts of menopause, treat yeast infections, and treat infertility. It hasn't been proven to do any of the above and can have mild to life-threatening allergenic reactions.


 * Motherwort (Leonurus cardiaca) is claimed to "tonify" the reproductive system (give it more "energy"/qi/etc.), balance hormones, and increase circulation to the pelvis.


 * Red clover (Trifolium pratense) is claimed to promote healing of the skin. There is no evidence that red clover heals the skin, and there is evidence red clover causes rashes.


 * Rosemary (Rosmarinus officinalis) is claimed to be antiseptic and stimulate circulation. Little research on rosemary in humans exists, and none substantiates either of these claims. However, rosemary has been used traditionally as an abortifacent; if we accept the verdicts of traditional medicine, then vaginally steaming when pregnant with rosemary is probably an even worse idea.


 * Oregano (Origanum vulgare) is claimed to be antiseptic and a "uterine stimulant". Oregano has certainly not been proven to be antiseptic, though it has antiparasitic potential in the intestines. Oregano also may cause miscarriages, which further advises against steaming while pregnant. We're not sure what "uterine stimulation" means, exactly, so it's difficult to assess it.


 * Sage (Salvia officinalis or other Salvia spp.) is claimed to "move blood and chi through physical and emotional obstructions". Sage can affect blood pressure; it usually reduces blood pressure in persons with low blood pressure and increases it in persons with high blood pressure, which is kinda not-good. We can't say anything about the chi, though.


 * Wormwood (Artemisia spp.) is claimed to have antimicrobial/bacterial/viral properties, induce uterine contractions, and treat bladder infections, fevers, open sores, constipation, diarrhea, and parasitic infections. Wormwood can cause vomiting and a variety of mental discomforts, and is neurotoxic in large doses.


 * Yarrow (Achillea millefolium) is claimed to be astringent (contract bodily tissues), cause "cleansing", and be antibacterial.


 * Rose petals are claimed to be really soft.  How this helps vagina steaming, we're not sure.

Of course, given its promoters' rather ... well-lubricated grasp of scientific concepts, we must consider the possibility that when they say "plants" they include fungi and microorganisms in that category, and are implying that vaginal steaming will somehow adjust the vaginal microflora.

It's very unlikely to, and even if it did, randomly mucking about with one's own vaginal flora is unlikely to be of benefit. The vagina naturally maintains its microflora in a near-optimal equilibrium, and actively disturbing that equilibrium is seldom productive and quite possibly unhealthy.

Cleans the vagina
Almost all supporters of vagina steaming mention (directly or indirectly) that vagina steaming "cleans up" down there. Because who doesn't want to be "clean"?

Depending on how someone sits, vagina steaming can either force steam onto the skin of the pelvic region or into the vagina.

If vagina steaming gets water into the vagina, then it is effectively a less-intense form of douching &mdash; since in both instances, water is forced into the vagina. Many believe that douching effectively cleans the vagina, even though little scientific evidence supports this belief; similarly, it's entirely possible that many incorrectly believe that vagina steaming has the same benefits. In fact, the acidic environment of the vagina effectively self-cleans, making douching and vagina steaming unnecessary.

These and other conditions make vagina steaming drastically increase the risk of vaginal infection.

If, on the other hand, vaginal steam is ineffective in getting steam into the vagina, then there is no benefit (other than a wet ass and some wasted time, of course).

Cleans the uterus
The formulation of a vaginal steam bath consists of aromatic, cleansing herbs that will penetrate into the uterine wall. The therapeutic effects of thermotherapy and aromatherapy contribute to the effectiveness of this treatment. Overall the bath aids as a uterine lavage or internal cleanse of the membranes that often accumulate incompletely flushed debris/fluids from cycle to cycle.

Any claims of cleaning the uterus are even more specious than normal for vagina steaming. Steam has very little access to the vagina, let alone the uterus. To quote Dr. Ghodsi:

And to quote Dr. Gunter:

Alternatively, supporters claim that herbs enter the bloodstream and flow to the uterus:

Since blood flows from the heart to the vagina to the heart, not the uterus, we're not quite sure what mechanism is in play here.

Reduces odor
Many supporters of vagina steaming argue that vagina steaming reduces vaginal odor.

Douching can mask vaginal odor, but doesn't truly remove it. Similarly, vagina steaming (which often contains good-smelling herbs ) probably can hide the odor of the vagina, without removing its source.

A low level of vaginal odor is natural, and there's no (medically necessary) need to mask it. Strong odor may be the result of infection; if so, it is best to see a doctor before douching or vaginally steaming, because hiding the odor makes it harder for the doctor to diagnose the issue.

Removes "toxins"
Some supporters go beyond claims of "cleansing" and claim that vagina steaming removes "toxins" from the vagina. Because the "toxins" that are apparently removed aren't specified, it's more likely that the term is a catch-all for "gross stuff that supposedly exists in my genitals" rather than anything meaningful.

Helps irregular periods
Vagina steaming is claimed to cure irregular menstrual periods   (those which have significantly more or less blood flow, happen significantly more or less often, are accompanied by pain or mental discomfort, or last for a long time).

There are many and varied causes for irregular periods, including stress, exercise, changes in weight, changes in diet, illness, changes in routine, hormone imbalances (with polycystic ovarian syndrome being most common), birth control pills, uterine fibroids, uterine endometriosis, cancer, and many more. This leads to two problems:


 * 1) False positives may be common. If somebody starts exercising (and thus solves their irregular period) and vaginally steams, they may incorrectly think the vagina steaming solved the problem.
 * 2) If vagina steaming is claimed to prevent all irregular periods, then it also must resolve or counteract all of these problems, which is simply ridiculous. Claiming to be a panacea is a hallmark of pseudoscience.

Treats abnormal growths
Vagina steaming is claimed to treat (abnormal growths in the uterus),    uterine  (abnormal growths outside of the uterus),        and/or cancer.

How putting gaseous water in the vagina with a tiny concentration of herbs (sometimes) could fix abnormal internal growths is unknown.

Presumably the steam uses its magical powers to identify the "good" growths from the "bad" growths and then somehow removes said bad growths.

This is especially ridiculous since steam has very little access to the vagina, and even less access to the uterus, where many of these growths occur.

Prevents vaginal infections
Vagina steaming is purported to reduce the risk of vaginal infections, including yeast infections,    and bladder infections.

This is basically the opposite of what probably will happen.

Balances hormones
The vagina is not regulating your hormones. Your brain regulates your hormones. Nuff said.

Putting steam into the vagina almost certainly cannot alter the body's balance of hormones. Even more certainly, if it does alter them, it probably won't balance them, given all the herbs claimed to be going up there.

Aids relaxation


Kind of when you were a kid and you pulled your shirt over your legs to sit on the vent during cold winter days. Another way to increase your benefit is to self-massage on your abdomen with your hands… or a vibrator. Yes, I know what I said. Perhaps vagina steaming "releases stored emotions and taps into the energy that is our creative potential." Or perhaps vagina steaming has nothing to do with it. The experience might be relaxing, since you have to stay in a warm, comfortable place for a long time. In this way, it might provide some of the same benefits of meditation.

On the other hand, even if you're as dry as the Sahara desert, it's probably a better idea to pursue a relaxing spa visit that doesn't risk vaginal burns and infections.

Aids fertility
There is absolutely no way this has any significant health benefit. The illusion that any hot air infused with some herbal spice would penetrate the vaginal barriers of your body and improve fertility, regulate hormones does not hold any water with me. Some supporters argue that vagina steaming helps increase fertility. For example, Dalene Barton writes:

They're wrong.

The first argument in favor of increased fertility is that "Niki Han Schwarz did it!" Niki Han Schwarz, who was the 45-year-old owner of a vagina steaming spa, had unsuccessfully tried to become pregnant "for three years" — until she vaginally steamed. (Or, so she says.) This evidence is flawed in numerous ways:


 * 1) This evidence is about as anecdotal as it gets, and can be explained entirely by Schwarz's regression to the mean.
 * 2) This evidence has a clear conflict of interest, since Schwarz stands to gain if vagina steaming becomes popular. While her biased opinion is not necessarily wrong, it is more likely wrong.
 * 3) This evidence omits major details. For example, Schwarz doesn't explain how she was trying to get pregnant. If she was doing, for example, other fertility treatments, this could falsely make it appear as if vagina steaming had caused the fertility.
 * 4) Finally, this evidence still doesn't provide any mechanism through which vagina steaming is supposed to help those sperm on their way.

The second argument is that vagina steaming "increases circulation". The idea goes that vagina steaming increases heat (obviously), that heat increases circulation (again true ), and that circulation increases fertility. (Increased bloodflow also increases the flow of oxygen and immune factors, which might be beneficial — however, they will not aid pregnancy. ) Indeed, increasing circulation in the kidneys has been shown to help pregnancy; so the idea is not totally insane. However:


 * 1) No known scientific studies directly support the idea that warmer vaginas increase fertility.
 * 2) Simply put, the effects of vagina steaming are extremely temporary. Unless someone is steaming for days on end, their bloodflow will go right back to normal extremely quickly.
 * 3) Scalding the vagina is probably bad for pregnancy.
 * 4) If increasing heat is the only goal, then a hot bath should aid fertility just as much as vagina steaming, at a lower cost and with fewer risks.
 * 5) If increasing bloodflow is the only goal, then almost anything (including exercise and better posture) should aid fertility just as much as (if not more than!) vagina steaming, at a lower cost and with fewer risks.

Finally, the third argument is that testicular steaming (which is administered in the same way and in the same place as vagina steaming) can also improve fertility.

In reality, warming the testicles inhibits sperm production and reduces fertility. The whole reason why they dangle from the body is to keep them cooler than the body's main temperature. If warm temperatures facilitated sperm production, men wouldn't have easily-kickable nutsacks.

Traditional medicine
It's a simple, relaxing treatment. You can imagine people doing this in the forest somewhere. For a taste of the New Age-i-ness surrounding vagina steaming, we turn to SoulVibrance:

Vagina steaming does have a history in Africa and South Korea:


 * Some argue that vagina steaming is an "old, respected treatment for women" and that this somehow makes it more likely to work. However, the long history of vagina steaming has no impact on its efficacy.
 * Some argue that vagina steaming is a traditional Mayan/Korean/African/Greek/Asian treatment and that this somehow makes it more likely to work.    However, the traditional use of vagina steaming has no impact on its efficacy.

Other claims of a "vagina steaming tradition" are tenuous at best.

Causes arousal
As Dr. Hilda Hutchinson states:

Combining arousal and the placebo effect is a great recipe for self-reported "good feelings" after a vagina steam treatment.

Causes infections
As noted above, vagina steaming is comparable to gaseous douching. Douching may upset the pH balance of the vagina, which upsets the balance of good and bad bacteria in the vagina, which, in turn, increases the risks of infection. People who douche are more likely to have vaginal infection, vaginal irritation, sexually transmitted diseases, pregnancy complications, and cervical cancer.

Furthermore, because the vaginal mucosa is highly absorptive, whatever gets shot up there is likely to enter the entire body. This is especially dangerous for vagina steaming, which may occur in public spas with less-than-sterile seating arrangements. This is also especially true for yeast, which loves the warm, moist environment that steam provides.

As Dr. Gunter puts it:

Causes steam burns
Vagina steaming forces steam onto the pelvic region and potentially into the vagina. Steam definitionally, in a normal room, must be 100° C; getting steam on you is like having boiling water spilled on you. Vagina steaming can cause steam burns.

Steam, just like boiling water, can cause burns; in fact, steam burns are far worse than burns from boiling water. This compounds the fact that the vagina is especially sensitive and not especially resilient. Burning oneself is always lovely; scalding one's genitals is slightly more so.

Many practitioners of vagina steaming recommend allowing the boiled water to cool first in order to attempt to avoid steam burns and lawsuits. This helps prevent burns. It also happens to change the process from vaginal steaming to placing-one's-vagina-over-hot-water-ing. At that point, vagina steaming presumably has the same effects as using a warm compress on the region, but with more potential for infection and irritation.

Causes vaginal irritation
Even if vagina steaming does not cause burns, it certainly has the potential to cause vaginal irritation. This may occur through adverse reactions to the plant(s) used (if any actually rise with the steam) or merely through the act of pushing heated water into the vagina and uterus. While inflamed genitals may not seem so bad, if there is a precancerous condition in the vagina, then vaginal irritation may exacerbate the condition. Chronic inflammation &mdash; by itself &mdash; is a known cause of several types of cancers.

Spreads STDs
Scientific evidence does exist on vagina steaming and STIs.

Vagina steaming is used to "dry" the vagina by limiting vaginal secretions. After "drying" their vagina, people then have "dry sex"; supposedly, a drier vagina increases the sexual pleasure for the person with a penis. However, dry sex can be excruciating and lead to tears on the vagina, which makes it easier to transfer STIs such as HIV/AIDS.

As Tinde van Andel et. al. state:

In addition, any intravaginal practices have a risk of transferring STIs.

Causes complications during pregnancy
Douching in general can cause complications during pregnancy,  and vagina steaming is comparable to douching. (Or, at least, if vagina steaming proponents want to argue that it's effective, then they must argue that it's similar to douching &mdash; or else it does almost nothing, and isn't worth the time.)

Most practitioners of vagina steaming warn against vaginally steaming while pregnant.

Causes contraction of the purse
Spas that offer vagina steaming services tend to have prices that range from about $20 to about $100. Considering that this service is the equivalent of (1) boiling water and (2) letting somebody sit over it for a little while, this is a pretty nice way (1) for spas to make money and (2) for customers to lose it.

Scientific evidence on efficacy
[A]sking for scientific citations at a holistic spa is rather like requesting chopsticks at an ice cream parlor: not only will they not have them, they won’t really understand why you’re asking in the first place.Not only is there potential to burn yourself if the steam's too hot, went these cautionary tales, but some gynecologists think the herbal steam might mess with good bacteria, which are vital to keeping women healthy and infection-free. [...] But as it turns out, nobody’s yet done a study on the practice. That was enough for us.

Unfortunately, no available studies have scientifically tested the efficacy of vagina steaming.

The closest approaches to such a study are self-reported surveys. Unfortunately, such studies are inherently unreliable. Furthermore, people report both positive and negative effects from vagina steaming.

As such, it is impossible to say that true empirical scientific evidence on the medical impacts of vagina steaming exists.

Publicly available
Prevalence and self-reported health consequences of vaginal practices in KwaZulu-Natal, South Africa: findings from a household survey 

This article contains a wealth of self-reported information about vagina steaming. For our purposes, a few statistics stick out: of those who currently practice vagina steaming, 9.4% report increased cleanliness, 64.0% report odor reduction, and 2.5% report relief of symptoms. Of those who have ever practiced, 7.3% reported genital irritation and/or pain, 1.5% reported genital itching, 0.2% reported genital bleeding or sores, and 0.9% reported (painful intercourse). This study is entirely self-reported and thus does not avoid any potential (positive or negative) incorrect self-diagnosis.

This article, while describing some of the known qualities of Satureja bachtiarica, states:

This would seem to support claims that vagina steaming, when accompanied with a herbal massage, can increase sexual satisfaction.

A multi-country study on gender, sexuality and vaginal practices: Implications for sexual health 

The WHO noted that:


 * 67% of women in Chonburi, Thailand vaginally steam
 * 86% of women in mainland Asia reported vaginally steaming after giving birth
 * 10% of women in Tete vaginally steam, 64% in order to increase male sexual pleasure via vaginal tightening, and 23% in order to dry the vagina

The article also noted, in general, that some recent studies suggest that those who perform intravaginal practices (such as vagina steaming) and especially those who have "dry sex" (for which people vaginally steam) have higher rates of sexually transmitted infections and HIV.

Prevalence, Motivations, and Adverse Effects of Vaginal Practices in Africa and Asia: Findings from a Multicountry Household Survey 

This article surveys numerous women across a large area in order to attempt to determine how many and why people perform vaginal practices, as well as if they have any adverse impacts. Vaginal practices in Africa were often explicitly linked to increasing sexual pleasure and maintaining partner commitment, while vaginal practices in Asia were more often linked to maintaining femininity and health. The article also notes that very limited evidence of the biomedical consequences of most vaginal practices exists.
