No matter what the occasion, boob sweat is always a nuisance. Whether you’re at a formal event and the room is burning up, causing you to sweat through your dress, or whether you’re exercising and expecting to sweat, it’s embarrassing and frustrating no matter what.

When our boobs sweat, yes, it feels nasty – but that’s not the only problem! The more moisture that builds up underneath our breasts, the more prone we are to yeast infections, blisters, and even odor. If you notice a smell when you take your bra off or when your boobs bounce, that’s a sure sign you’re sweating quite a bit and might already have a little yeast infection.

Excess sweat also causes us to itch, which leads to dry and discolored skin since our breasts are so sensitive. It also puts us at a higher chance to develop heat rashes and uncomfortable boils on our breasts.

If you have large breasts, you’ve probably grown to wear dark clothing more often than you used to because boob sweat, unfortunately, is inevitable a lot of the time. Do not stress any longer! There are absolutely precautions you can take to keep sweat at a minimum. My goal today is to provide you with information on how to prevent boob sweat, so maybe you will have one less thing to worry about where your boobs are concerned!

Why does my body sweat?

The sweat is your body’s way with dealing with heat or stress.

Unfortunately, this can be a huge pain to us. By sweating, our bodies help us thermo regulate our internal body temperature. Sweat cools our skin temperature by “evaporative cooling”. This is hugely effective in bringing down our temp because your blood vessels widen up and expose as much of their surface area as possible to the skin. This way, heat is whisked away when the sweat evaporates and leaves you feeling relieved!

When you develop a rash or skin irritation, it is called dermatitis which literally means skin inflammation. The exact reason for the skin inflammation becomes a little more cryptic and difficult to nail down. Hopefully by going over the common symptoms and causing agents of dermatitis, we can figure out how to help your boobs!

The culprits of skin complications

Moisture is the first step in developing an issue (usually). If there is moisture, and skin is in contact with itself, it can cause a myriad of problems if left to fester. Even if skin is just tacky with sweat it can be an issue. Humidity in your bra and top, and sweat or clothing wet from water can be troublesome. This can lead to skin irritation from our next enemies on the list, and can be extremely painful in combination with #4.

Intertrigo sounds like such a gross thing to have on your body. It’s just the fancy name of the rash that shows up when skin is in contact with skin too much. In all truth, fungus is everywhere. When fungus begins to grow out of control and is unchecked, it’s a problem! Fungus loves to grow in environments where humidity is high in dark and warm places. Now if this sounds like your bra, we need to address this issue! Regular gentle washing of your bra can help make sure fungus doesn’t call your undergarments home. Tinea fungus (athlete’s foot and ringworm) is common, Candidiasis (common yeast infection) among may others.

Bacteria are present at all times and all over the surface of your skin. Most people would be amazed at what you would find if you took a swab of your skin and let it grow! Staphylococcus is more abundant than you want to imagine. Now mix this with irritated and inflamed skin… Very bad concoction. Our immune systems can handle a lot, but our skin is our most valuable first line of defense. If you have a rash or are bleeding (skin is broken open) that’s a heavenly gateway for any kind of pathogen that wants to infect your body! Keeping things dry and clean is the best way to make sure bacteria don’t wreak havoc on your body.

Poor fitting bras are really the worst culprit on this list. The reason I say this is because they can surely make both #2 and #3 an issue. A bra that fits poorly will likely chafe against damp and sweaty skin. Over the period of a day, it is probable the skin has been rubbed raw, and anything growing on your skin can meander on into your skin (VERY BAD!). Making sure your bra fits securely is one of the first things you should do before even trying the remedies I’ll recommend. There’s no point in patching yourself back up if you’re not going to eradicate the problem at the start!

Boob sweat happens to everyone

It’s a common problem, don’t worry! You’re not alone in this sweaty struggle.

It’s springtime, and soon it will be summer. Daytime temps are heating up, and your girls are sure to be the first to notice.

Undoubtedly, there will be countless women (men, too) in your general vicinity experiencing the same symptoms and repercussions as you! The aftermath of breast perspiration can vary greatly, especially if left unattended.

So what can you do about it?

If you’re on a budget, you can prevent boob sweat by sticking panty liners in the bases of your bra cups

The panty liners will absorb most of your moisture and prevent sweat from showing through your clothes or running down the trunk of your body! You might even keep some extra panty liners in your purse or wallet in case you’re going to be out for a long time and need all day or all night coverage.

Some people recommend putting extra padding or inserts in the bottoms of your cups, but panty liners work better for many women because they have that sticky underside that holds them in place. It would be pretty embarrassing if you put extra padding in your bra and it somehow wiggled out, falling to the floor in front of everyone at a dinner party!

CupCare disposable bra liners

These are shaped to fit the bottom halves of your bra cups better than panty liners, so they should absorb more moisture and provide you with better coverage. They have a sticky down side, too, and can be thrown away after you use them.

Belly Bandit “Don’t Sweat It” Bra Liner

This liner is made of bamboo. It’s stretchy and fits all the way around your trunk. You slip it on underneath the bottom of your bra and it catches all sweat and prevents rashes.

Apple cider vinegar

ACV is great for all sorts of ailments, including curing the common cold, balancing blood sugar, removing warts, and clearing yeast infections. It’s antifungal, so it’s healthy for your skin. Pour some over a cotton ball and pat it over and around your breasts. Let your skin air dry for about fifteen minutes. The apple cider vinegar won’t completely keep sweating away, but it will certainly minimize sweating while keeping you from getting a rash, a yeast infection, or chafing.

Argan oil, tea tree oil, and coconut oil

Argan Oil

So you’ve used argan oil to tame unruly hair and maybe even to moisturize your face, but have you ever used it on your boobs? You can evenly distribute several drops of argan oil all over your breasts – under them, between them, on the tops, and on the outer sides – and you should experience minimal moisture, odor, chafing, and rashes. Argan oil is antibacterial, so what moisture you do have will be less likely to contribute to a nasty infection.

It will also help your breasts the same way it helps your face! Because argan oil has a high vitamin E content, it’s very moisturizing and should help alleviate any dry, cracked, and even discolored skin under your breasts.

This Morocco native is called liquid gold for a reason. Many women have acne on their breasts – because hello, sweat – and argan oil should not worsen that a bit. In fact, argan oil is a healing oil and should actually soothe your acne.

Coconut oil

Coconut oil has both anti fungal and anti bacterial properties! Not only that, but it will lubricate your skin and hopefully lessen any rubbing across the area. Be careful when rubbing it on if you are unfamiliar with coconut oil; this stuff melts VERY quickly and will turn a huge mess if you use too much.

Tea tree oil

Tea tree oil has natural anti fungal properties, and smells great. I wouldn’t recommend use on areas with open cuts, though, since essential oils are so concentrated. You can – and should – mix it with a carrier oil to avoid skin irritation.

Olive oil, coconut oil, almond oil, and jojoba oil are all great carrier oils to use.

Aloe vera gel

A lot of people only use aloe vera gel to soothe a sunburn, but did you know it’s great for sweating and chafing, too? If you’re already chafed, aloe vera will act as a cooling agent over your chafed areas. This will significantly help eliminate discomfort if you have to wear a bra again before your chafing is gone. Aloe is also an inflammatory so it should help any raised lines or bumps caused by friction or sweating. Aloe vera might not prevent sweating, but it will prevent and treat the side effects that come with sweating. If you pair aloe vera with one of my other recommendations – like panty liners – you should suffer minimally from your breasts sweating.

Lush Silky Underwear Dusting Powder

The description for this product reads “Light, sophisticated jasmine-scented powder with added cocoa butter to dust over your skin, leaving it soft, smooth, and seriously sexy.” This dusting powder will help your breasts gently glide across each other and your torso without causing irritation. It’s supposed to absorb moisture, too.

Underboob Breast Sweat Absorber

The Underboob Breast Sweat Absorber is an elastic band you slip on around your bustline. It’s only available in band sizes 28 through 38, so it won’t work for everyone, unfortunately. It’s made of cotton and absorbs most, if not all moisture. It will stay on even without a bra, so if you wear it under your clothes by itself it will still do its job.

Decrease your salt intake

If you consume too much salt, your whole body will sweat more, thus making your boobs sweat easily. Changing your diet is one of the most challenging things people have to do sometimes, but it’s an important change if you want your boobs to have less reasons to sweat.

Boob deodorant

There are hundreds, if not thousands, of people who steer clear of deodorant because it usually contains harsh, dangerous ingredients like aluminum or parabens. Luckily there are deodorants specifically made for breasts, and a lot of them are free of these chemicals! A lot of women swear by Boobalicious Breast Deodorant by Marvelous Melons. I’ve personally never tried it, but it’s supposed to be free of those chemicals and it has great reviews.

If you don’t want to try boob deodorant for whatever reason, consider trying a product called Fresh Breasts by Fresh Body instead. Luckily this product is free of aluminum, parabens, and talcum powder. It’s also hypoallergenic! Fresh Breasts is a lotion that turns into a smooth powder when you put it on. It prevents sweating and chafing. It’s fragrance free so you don’t have to worry about any harsh perfume irritating your skin.

Make sure your bra fits properly

This is crucial. First, make sure you actually know your bra size! I know that might sound like a silly thing for me to say, but I mean it. If you’ve never calculated your size yourself and have been using whatever size a bra fitter has told you is correct, there’s a good chance you are not really wearing the right size. Check out my guide here to learn how to calculate your proper size at home.

If you’re wearing the wrong bra without knowing it, there’s a good chance your breasts are squeezed and smushed into cups that are way too small, promoting sweat and excess moisture. Even if you take the proper precautions to prevent sweating, none of it will matter if you don’t get yourself in a bra that fits!

If you don’t have a soft tape measure handy and wonder if you’re wearing the right size, ask yourself the following questions:

Are your breasts overflowing your bra cups?

Are they falling out of the bottom of your bra?

Is the band squeezing your ribs or back so much that you’re uncomfortable?

Are the straps digging into your shoulders?

Are you wearing your bra on the last hook?

Is your underwire poking you?

Is the center gore of your bra pushed away from your body?

Even if you only answered yes to one of these questions, you’re more than likely in the wrong bra. Fix that, and then move on to my other suggestions!

Your health is important

If at any point you develop a rash or a severe allergic infection, don’t hesitate to see a dermatologist! Infections can be serious, and ignoring them can escalate an initially minor situation. Not only can you do yourself harm by ignoring an infection or serious rash, but they can fester and develop into dark scars under or around your breasts.

Whether the rash is caused from your breasts sweating or one of the products you tried as a remedy, you should never, ever ignore your symptoms! See a doctor if you’re concerned about an infection.

Skin tags – another reason to keep dry

Skin tags, or acrochordons are those little extended mole-like fleshy bits that people sometimes get around their breasts, torso, and neck. These often come about when skin is coming into contact with skin too often, and after reoccurring rashes. Some people are more prone to acrochordons more than others, it depends on breast size, body weight, and genetics in general. Either way, here are a few ways to make sure you don’t develop these little guys.

Ventilate the trouble area with fresh air

Keeping air flowing and moving around where humidity would otherwise build up is good for preventing microbe growth. This solution can be made possible with some of the following tips, such as wearing loose fitting clothing whenever possible. This way, your body can sweat if it needs to, but that sweat moisture can evaporate and escape. Leaving you cool and dry instead of damp and smothered feeling.

Wear bras that fit you properly

Making absolutely sure you are wearing a bra that fits you correctly is of utmost importance. I know I sound like a broken record here, but I can’t say it enough. Not only will wearing a bra prevent discomfort like rashes, infection from bacteria and fungus, but it will literally save your neck and back. Support is key – make sure your bra is doing its job.

Bathe regularly and thoroughly

Yes, I know this sounds really silly; some stranger on the internet telling you to take a bath. But seriously, bathing is about more than just rinsing off. I use a moisturizing body wash, and an exfoliating pad. You can buy them just about anywhere and they’re super cheap. They are very abrasive, but work very well. By removing dead skin, much and debris from you body, you’re doing yourself a huge favor. Smells, microbes, and dead cells can’t accumulate this way.

Loose clothing

If possible, wear loose fitting clothing. I’m not talking about dressing dumpy or wearing nothing but baggy dad shirts all the time… Wear a tunic, or a dress that doesn’t smother you in layers of fabric. This loose clothing will allow for more ventilation, and is more likely to allow for the garment to remain dry.

Dry clothing

Avoid wearing wet clothing for extended periods of time whenever possible. If you’ve hit the gym and are soaked with sweat, try to get that off as soon as humanly possible. Many gyms have showers and dressing rooms for you to rinse and change into an extra pair of fresh clothing. Even if you’re planning on going straight home – shower at the gym anyway, if this option is available to you. You’ll thank me later, I promise. Wet clothing traps moisture (obviously), and is more likely to rub and chafe against your skin.

Clean bra

Always wear a clean bra. Gently wash you bras after every few wears or so, especially if you had a long and sweaty day in one. Bras accumulate dead skin cells, salts and oils from sweat, and are prime breeding real estate for fungus and bacteria when they’re a warm and humid environment. Gross! So clean your bras regularly, and give your body the best fighting chance against microbes looking to set up camp.

Go Braless

I understand that this is much easier for some people than others. Whether it’s your comfort level, the environment you work in, the size of your breasts, etc. I totally understand why this may be taboo. Regardless, I have to admit it is another convenient way to avoid rubbing and rashes. Though skin tags can be caused by skin on skin contact, you can also look into an unpadded bra. This way, you have a little protection without the stifling bra padding getting in the way.

You’ve got the knowledge it takes, now find your best solution. The most important things to keep in mind are keeping your bras and skin as clean as possible, and making sure your bra fits. Lastly, always understand that going in to see a dermatologist is okay! They’re here to help and are wonderful sources of information. Your health is most important.

Heed the advice I gave you today

Stop stuffing your cups with toilet paper! Boob sweat can be an annoying, disgusting part of having large breasts. Luckily for us busty ladies, there are countless products on the market to alleviate a lot of the stress that comes with sweaty breasts, and some of those products are already sitting in our homes.

If you have extra sensitive skin, I recommend you skip the products that have a fragrance and use either unscented boob deodorant or powder or use some of the elastic bands or cup liners instead.

Remember to pay close attention to any rashes or infections that develop on or around your breasts, and keep them dry as much as possible. Do not let your boob sweat control your life!
