It happens not because this area necessarily sweats more than the rest of the body — rather, moisture tends to get trapped where your breasts meet your torso. “The skin hangs and folds on itself, leaving less air to evaporate the sweat,” explains dermatologist Dr. Rachel Nazarian.
Heat, sweat, and friction in the crevasses under your breasts, (a.k.a., your “under boob area”) not only make you stink, they make your clothing wet. This area is a breeding ground for itchy rashes and unattractive, red bumps.
Protein breaks down into amino acids, which the body converts into ammonia. The body then releases this ammonia through urine and sweat, which may produce an odor. Dehydration can also make the sweat smell like ammonia. This is because the body needs water to get rid of ammonia through sweat.
Use antiperspirant—yes, under your boobs
While it may seem strange to apply an antiperspirant anywhere other than your underarms, it works, Dr. Hazen says. "Antiperspirant can be used anywhere—on your feet, hands, and even under your bra," she says.
While sweat itself doesn't smell, you may develop body odor when there is the presence of bacteria on your skin. This is particularly why sweaty breasts smell sour or musky. Body odor comes from bacteria on the skin, which breaks down sweat produced by the apocrine glands.
You've seen it (or felt it) before: Those patches of moisture that gather under your breasts and sometimes soak through your shirt. This phenomenon is what's known, rather aptly, as underboob sweat. And it can strike at any time.
In hyperhidrosis, your body's sweat glands overact. This overactivity causes you to sweat a lot, at times and places where other people wouldn't. Sometimes, a medical condition or emotion (like anxiety) triggers excessive sweating. For many people with hyperhidrosis, managing symptoms can be a constant challenge.
1 Try a moisture-wicking bra. 2 Wear loose cotton clothing. 3 Use aluminum-free deodorant under your breasts. 4 Sprinkle on baby powder to prevent chafing.
Trimethylaminuria (TMAU) is an uncommon condition that causes an unpleasant, fishy smell. It's also called "fish odour syndrome". Sometimes it's caused by faulty genes that a person inherits from their parents, but this isn't always the case. There's currently no cure, but there are things that can help.
If you have diabetes, a change in body odor could be a sign of diabetes-related ketoacidosis. High ketone levels cause your blood to become acidic and your body odor to be fruity. In the case of liver or kidney disease, your odor may give off a bleach-like smell due to toxin buildup in your body.
Squeezing into your regularly fitting bra may result in some light bruising around the bra line or some more intense markings due to the water retention, puffiness, and whatever else you experience during that time. That is okay.
It is also absorbent, so in a way, baby powder will absorb sweat. It will also reduce friction, help keep your skin cool, mask odor, and act as an extra layer of protection for your skin. Essentially, baby powder can absorb sweat and also help in lowering sweat production.
Antiperspirants are considered the first line of treatment for excessive sweating and can be used nearly anywhere on the body where sweating is a problem. That's right, antiperspirants are not just for your underarms – you can use them on your hands, feet, face, back, chest, and even groin.
Treatment for a yeast infection under your breasts may include an antifungal medication. Your healthcare provider may recommend an antifungal cream, ointment or other solution. You can buy many antifungal creams over-the-counter.
Use an Anti-Chafing Powder
This boob-rub friction also creates heat, which kicks the sweat into overdrive. Baby powder is a popular choice for absorbing sweat, reducing odor, and guarding against rashes and chafing. One downside to baby powder is that it's usually absorbed pretty quickly.
Despite our best efforts to keep them clean, towels often develop a less-than-fresh smell. One of the main causes of this is detergent build-up. Over time, soap residue accumulates in the fibres of the towels, stopping them from absorbing as much water as possible, and from drying as well as they could.
Sweat also naturally moisturizes the skin and protects it against infection. Sweat is mainly water and sodium chloride, but also contains small amounts of potassium, calcium, ammonia, urea, lactate, and ethanol. When sweat mixes with bacteria on the skin, it can produce a smell, which may smell like vinegar.
Some foods and medications, such as asparagus or certain vitamins, can cause a noticeable urine odor, even in low concentrations. Sometimes, unusual urine odor indicates a medical condition or disease, such as: Cystitis (bladder inflammation)
