How to Prevent Underarm Sweat (An Exhaustive List of Solutions)

Are you tired of hiding underarm sweat stains and managing your sweat day in and day out?

You’re not alone. 4.8 percent of Americans suffer from excessive underarm perspiration, and this number is even higher for other countries.

Embarrassing, visible sweat marks can lower your confidence and hold you back in your career and social life. Sometimes underarm sweat can be so bad that it leads to anxiety and depression.

The good news is, you’re not powerless in the battle against sweat. In this blog post, we’ll talk about how to prevent underarm sweat and give you seven tips for success.

How to Prevent Underarm Sweating

  1. Wear antiperspirant (correctly)
  2. Sweat-proof your wardrobe
  3. Wrangle your stress
  4. Watch what you eat and drink
  5. Try natural sweat solutions
  6. Talk to your doctor about prescription drugs for hyperhidrosis
  7. Consider other procedures for underarm sweating

Let’s dive into the first tip:

1. Wear Antiperspirant (Correctly)

Antiperspirant is the most common go-to sweat deterrent. It contains aluminum which clogs your sweat ducts and makes you perspire less. But most people use it wrong.

To get the most out of your antiperspirant, you need to:

  • Apply it to dry armpits: Avoid swiping on antiperspirant right after you hop out of the shower. Even a tiny amount of water can block the aluminum from soaking into your glands.
  • Make it a part of your bedtime routine: Instead of applying antiperspirant in the morning, do it at night. Doing this gives the aluminum compounds more time to seep into your glands and create sweat plugs.
  • Dress after it’s dry: When you slide your shirt over wet antiperspirant, it rubs off and becomes less effective. Wait a few minutes before dressing or use a hair dryer on the lowest setting to air out your armpits.

It’s also important to wear an antiperspirant that’s strong enough .

The key is to look at the percentage of aluminum content. Antiperspirant contains anywhere from  10 to 30 percent aluminum depending on whether it’s an over-the-counter or prescription brand. You may want to try a higher concentration if your current antiperspirant isn’t working.

2. Sweat-Proof Your Wardrobe

If you avoid colorful and tight-fitting clothes because you’re afraid of sweat marks showing through — stop. There are better ways to sweat-proof your clothing.

Wear a Thompson Tee Sweat Proof Undershirt

Whether you sweat occasionally or 24/7, the Thompson Tee is an essential wardrobe staple you need in your closet. This undershirt:

It gives you the confidence you need to tackle anything in life without worrying about sweat.

Don’t believe us? Try one for risk-free for 30 days. If it doesn’t stop your armpit sweat from staining your clothes, we’ll give you your money back.

Can’t wear an undershirt all the time?

Wear Clothing Made of Light, Breathable Material

The best materials for reducing sweat are natural, water-loving fibers like cotton, linen and rayon from bamboo. The worst materials for sweat prevention are synthetic, water-resistant fibers like polyester, rayon and lycra-cotton blends.

While it might seem counterintuitive, you want your clothes to soak up sweat, not repel it.

Water resistant materials push moisture away from your skin straight onto your clothes. Absorbent materials soak up sweat to prevent it from reaching your outer layer.

3. Wrangle Your Stress

Between a hectic work and home life, everyone deals with stress. And stress is a major catalyst of underarm sweat.

To make matters worse, worrying about visible sweat marks signals your body to sweat even more. It's a vicious cycle — but you can stop it.

Learning how to manage stress can help you prevent underarm sweat — and just feel happier.

Reducing stress does far more than improve your mood. To clear your mind and reduce the anxiety associated with sweating try:

  • Acknowledging feelings of stress
  • Creating actionable to-do lists
  • Getting into daily routines that help you feel calm and collected

If you feel a bout of stress coming on, take deep breaths, and remind yourself that everything will be OK. You can also prepare for unexpected stress sweat by:

  • Keeping a fan near your desk to help you cool down when tensions get high
  • Bringing an emergency sweat pack to work complete with antiperspirant, a Thompson Tee and an extra shirt
  • Avoiding caffeine, alcohol and spicy or sweat-inducing foods before a presentation or meeting

4. Watch What You Eat and Drink

What you put in your body affects how much you sweat. If you struggle with excessive perspiration, avoid these foods:

  • Stimulants like alcohol and caffeine : Alcoholic and caffeinated beverages release chemicals that raise your heart rate, body temperature and blood pressure, causing you to sweat.
  • Hot foods like soup and coffee : These foods increase your body temperature from the inside out and trigger a sweat response.
  • Spicy foods like hot sauce and jalapeños : Capsaicin, a chemical that naturally exists in spicy foods, stimulates nerve receptors in your mouth and tricks your body into thinking it’s hot, making you sweat.
  • Pungent foods and spices like curry, garlic and cabbage : Although these foods won’t necessarily make you sweat more, they release an unpleasant odor through your sweat when you digest them.

Now that you know what to avoid, you may be wondering, “Are there any foods that help reduce sweat?” Yes — foods and beverages that regulate your body temperature and promote digestion help keep sweat at bay.

To reduce sweating, consume foods rich in:

  • Water
  • Calcium
  • Potassium
  • Fiber
  • Magnesium
  • Vitamin B

Water, calcium and potassium keep you hydrated. Water cools your body down while calcium and potassium regulate the flow of fluids through your body.

Fiber, vitamin B and magnesium promote digestion. The harder your body has to work to metabolize foods, the higher your body temperature becomes and the more you'll sweat. Eat foods that are easy to digest, and you’ll sweat less.

5. Try Natural Sweat Solutions

Looking to take the natural route to sweat prevention? Try these natural solutions:

  • Apple cider vinegar: Apply ACV directly to your skin to close up your pores and reduce sweating. For best results, apply it your underarms with a cotton pad before bed to give it enough time to seep in.
  • Tomato juice: Consume a glass every day or apply it to your skin to reduce sweat.
  • Green and black tea: Drink a glass of green tea every day to promote digestion and minimize perspiration. Apply black tea directly to your skin to shrink your pores.
  • Cornstarch and baking soda: Both of these ingredients absorb water naturally. Mix two parts cornstarch and three parts baking soda to create a natural antiperspirant deodorant powder.
  • Potatoes: Potatoes are high in potassium and very absorbent. Eating them can help regulate your body temperature. Rubbing a raw slice of potato on your armpits every day can help you feel drier.
  • Lemon: Lemons contain citric acid which constricts sweat glands and lessens perspiration.

6. Talk to Your Doctor About Prescription Drugs for Hyperhidrosis

If your underarms sweat excessively without warning, you may have a medical condition known as axillary hyperhidrosis. If you’ve tried everything to prevent armpit sweat with no success, talk to your doctor about prescription drugs to prevent sweating:

  • Anticholinergics: Drugs that block chemicals that allow certain nerves to communicate with one another, reducing body sweat
  • Beta Blockers: Medications that impair nerve impulses that cause sweating
  • Qbrexza: A new anticholinergic treatment from Dermira that comes in wipe form

It’s also critical to understand the side effects of anti-sweat medications and speak to a doctor before using them to prevent underarm sweat. For more information on the side effects of these drugs, check out this blog post.

7. Consider Other Procedures for Underarm Sweating

In hopes of a more permanent sweat solution, many people turn to cosmetic procedures and surgeries. Although some have success with these types of treatments, they’re not always effective.

Over the years, the surgeries and procedures doctors have recommended to prevent underarm sweat have changed. Here is an updated list of those deemed safe for most patients:

  • Botox: Chemical injections that block sweat gland activity
  • Iontophoresis: The application of mild electrical currents to your underarms to disrupt nerve transmissions that cause sweat
  • miraDry: Microwave technology that destroys your sweat glands
  • Laser treatment: A procedure that heats your sweat glands until they become inactive

Non-Recommended Surgeries and Procedures

Most doctors no longer recommend endoscopic thoracic sympathectomy (ETS) for sweat prevention. ETS is the destruction of nerve endings responsible for sweating and can result in serious side effects like heart problems and droopy eyelids.

About 70 percent of patients also experience compensatory sweating after ETS. Compensatory sweating is when you experience less sweat in one place but more in another. Want to know what ETS surgery is really like? Check out  this video to hear about Thompson Tee Co-Founder Randy Choi's experience.

When it comes to choosing a sweat prevention method, it’s important to remember that everyone is different. What works for one person, might not work for you.
