Why Do You Sweat So Much Between Your Breasts?

Why Do You Sweat So Much Between Your Breasts?

Biologically speaking, sweat is an excellent thing for our bodies. Sweating allows our body to regulate internal temperature on hot days or while exercising. However, while sweating may be necessary for our bodies, we do not always get to choose where we sweat, including under our boobs.  Therefore, if you notice underboob sweating, it is important to treat or prevent it to avoid chafing and skin irritation. Treating boob sweat is easy and may be done with items you may already own.

Why exactly do our boobs sweat?

Our bodies need to maintain a healthy temperature between 97 and 99 degrees Fahrenheit. When our body temperature gets too hot, we sweat to release moisture. That moisture then evaporates into our skin to cool our bodies down. We sweat under our breasts or between our cleavage because the skin folds and bra lines tend to have a more challenging time absorbing perspiration and therefore cause that uncomfortable boob sweat.

Why does my boob sweat smell?

There are two different types of sweat glands, eccrine and apocrine. Apocrine glands tend to create that foul smell because they release substances such as fat and proteins when they release sweat. The apocrine glands then mix with normal bacteria found on the skin, creating the smell we all know as body odor. Apocrine glands are located in the groin, around the breasts, and the armpits.

Can hormonal changes cause boob sweat?

Hormonal changes are common throughout a woman's life, such as during their menstrual cycle, pregnancy, and menopause. Hormonal changes may contribute to under-boob sweat because of the changes in estrogen and progesterone. These hormone fluctuations may cause you to experience sweating, most commonly known as night sweats or hot flashes.

How can I prevent boob sweat?

Baby Powder

When most people think of baby powder, they only assume it is made for babies and diaper rashes. However, don't let the name fool you; baby powder also provides many advantages for adults. Baby powder is a very effective option to help prevent boob sweat. It works by absorbing sweat, reducing odors, and creating a protective layer from friction, causing a rash.

Moroccan Argan oil

Moroccan Argan Oil has grown in popularity within the beauty industry for its extraordinary nourishing and moisturizing abilities. Argan Oil is a natural product that contains Vitamin E, healthy fatty acids, and antioxidants. Some believe that Argan Oil is even more effective than coconut oil in treating skin conditions. Apply only a few drops of Argan Oil under your breasts and between your cleavage to reduce boob sweat, discomfort from friction, and odors.

Sweat proof Bra


Proof® has you covered whether you are hitting the gym or going for a night out on the town. 

Wear Loose Clothing

Air circulation is essential to help prevent boob sweat. So while we may not feel comfortable forgoing a tight-fitted bra, consider wearing a loose top. The more air circulation promoted throughout the top of your body, the better chances for less boob sweat. In addition, air may help evaporate any boob sweat that appears.

Aluminum-free Deodorant

While antiperspirants reduce the amount of sweat you may have, most contain aluminum. Deodorants, however, do not always contain aluminum and may be a better option for boob sweat, especially since you are wearing it under your breasts. Deodorants target the bacteria, reduce the smell, and create a thin layer of protection from sweat.

Body wipes

Body wipes are easy and discrete to keep in your purse or bag. In addition, body wipes are gentle on your skin, and some do not contain any perfumes if you choose. Body wipes allow for a quick freshen-up to decrease odors, clean your skin, and allow for a mild fragrance to promote a fresh feel.

Should I worry about boob sweat?

Boob sweat is normal, and almost every woman will experience it at some point. While there are ways to prevent and treat boob sweat, it may be uncomfortable nonetheless. Consider seeing your care provider if you notice boob sweat does not improve with the over-the-counter solutions.
