If you have excessive armpit sweating, consider applying an antiperspirant at night (2023)

With the exception of professional athletes and sauna lovers, most of us live by the motto:Don't ever let them see you sweat. (Fun Fact: That came from a1984 advertising campaignfor Dry Idea Antiperspirant, and yes, that's Carol Burnett!)

Sure, it's completely natural — "Sweat's primary function is to cool the body," he saysDee Anna Glaser, MD, Professor in the Department of Dermatology at St. Louis University – and nothing to be ashamed of. That said, pit stains will never be desirable and always have beenfearfulor jittery can stimulate the sweat glands to work harder, it makes sense that you wouldn't want to radiate your emotional state in that particular way.

And if you haveHyperhidrosis— the medical term for excessive sweating all over your body — the problem is far more than just aesthetic. "It can profoundly affect a person's life — it can affect an adult's career choices or limit opportunities," he saysMaral Skelsey, MD., a clinical associate professor of dermatology in Georgetown, as they may have to choose jobs that don't involve speaking in front of a group or shaking hands, or that don't involve changing clothes several times a day. “I've treated teenagers who don't raise their hands in class. One said, 'I know the answers, but the teacher doesn't know that I know,'" added Dr. added glazier.

Why do our armpits sweat?

We have millions of sweat glands all over our bodies — the greatest concentration is in our hands and feet, says Dr. Glaser, but our armpits are another hotspot. Most of these areeccrine glands, which emit a clear, odorless liquid that cools us as it evaporates. But your armpits and other hairy parts have it tooapocrine drusen, which expel a thicker liquid, also odorless; If this liquid interacts with bacteria on your skin, don't smell too good.

A common myth is that productive sweaters have morebody odor, but that's actually not the case. "People who sweat a lot tend not to smell," says Dr. Glaser because the bacteria are washed away and there is no stench. "People who don't sweat as much might be more likely to notice an odor."

Another mistake? We sweat out toxins. "Sweat consists almost entirely of water," says Dr. skelsey The rest is loudInternational Hyperhidrosis Society, is salt, urea and a little carbohydrate and protein. Fortunately, our kidneys and liver do a good job of detoxification.

What Causes Excessive Sweating?

First of all, there are two types of hyperhidrosis: primary and secondary, and they have different causes.

The primary variant starts when you're young — even toddlers can have super sweaty hands and feet, but those whose armpits are the main spots usually show it soon after puberty or as young adults, says Dr. glazier. Experts aren't sure why some people get hyperhidrosis, but suspect it's genetic since it can run in families. Because sufferers have normal sweat glands, the theory goes that the hypothalamus, a part of the brain that, among other things, tells your glands to produce sweat, is sending those glands an erroneous message.

The secondary kind shows up when something changes in your body, such asMenopause(Hello, hot flashes and night sweats!), an underlying medical reason (like a thyroid or lung condition), or you're taking a medication that's messing with the same brain signals. Secondary hyperhidrosis "tends to result in more diffuse sweating," meaning not just in the armpits, and can show up as you get older, she says.

How do I know if I have hyperhidrosis?

The state that worksan estimated 15.3 million peopleworldwide, needs to be diagnosed by a doctor, usually a dermatologist, but if you've had excessive, bothersome, visible sweating at least once a week for six months or more, these are signs you might have it, says Dr. skelsey

The other big factor is how much your sweating affects your function and how much it bothers you. Some people objectively sweat buckets, but if it's not a big deal to them, there's no need to treat it, says Dr. Glaser, adding that excessive sweating may increase and decrease, but doesn't go away completely. Some excessive sweaters can do it on their own most of the time with antiperspirants, but for special occasions (let's say you're a bridesmaid at a wedding and planning to be photographed dancing the night away) they're looking for a next-level treatment. "If that's what they come to me for, it probably bothers them a lot," she says.

How do I stop armpit sweating?

There is afew treatments, each of which has its own advantages, disadvantages and side effects.

  • Clinical strength antiperspirants.Whether you find your sweating severely excessive or not, this is the easiest first step. "I always start with clinical-strength antiperspirants," says Dr. skelsey "They're a lot more effective than regular ones -- especially when they're used properly." That means reapplying them at night and in the morning. (Because you sweat less at night, the drug can get into your glands better.)
  • Botox injections.If antiperspirants don't work or irritate your skin, you can opt for themChrissy Tiegen did itand get this neurotoxin (perhaps best known for smooth foreheads) injected shallowly into your pits. It works by blocking the secretion of the chemical that activates your sweat glands.Botox shotsin this area usually last about six months, says Dr. Skelsky, sometimes longer.
  • Qbrexza.Theprescription towel(You Wipe Your Pits) contains an ingredient that inhibits one of the neurotransmitters on the sweat glands, resulting in reduced performance. "It was very effective and has been studied in children," says Dr. Glaser, who was involved in the research leading to FDA approval.
  • miraDry.This is the only non-surgical, FDA-approved procedure that permanently reduces sweating by zapping your armpits with thermal energy to destroy the sweat glands altogether. "Some patients are afraid of losing these glands," she saysKaryn Grossman, MD., a dermatologist in Santa Monica, CA who offersthe treatment. "However, it's important to note that the armpit contains only 2% of your body's sweat glands," and your other glands will continue to cool you down. While some people may completely ditch deodorants and antiperspirants after a treatment or two, says Dr. Glaser that some hyperhidrosis patients still need to use some. "They say they sweat normally after the treatment," she says.

bottom line:You don't have to suffer in sweaty silence because there are many safe and effective ways to stop the deluge.
