Under breast smells: How to Stop Underboob Sweat Once and for All


Potential Causes For a Rash Under Boob

Nothing’s worse than getting a rash in a sensitive area. Not only is it physically uncomfortable, it’s also not fun to talk about. If you’re dealing with a rash under your boob, you may be feeling this discomfort. Don’t panic: There are multiple reasons you may be experiencing this symptom, and they’re pretty common, especially in the summertime. We asked experts about the potential causes for rashes under your boob so that you can seek relief and feel your best.

Is your rash itchy and red?

“These are signs of intertrigo, a harmless rash that occurs when friction, moisture and heat irritate the skin in body folds like the breasts and underarms,” says Laura Corio, MD, author of The Change Before The Change: Everything You Need to Know to Stay Healthy in the Decade Before Menopause (Buy from Amazon, $18). “The rash is often more severe in the summer, as warmer temperatures ramp up the production of pore-clogging oils and allow bacteria, yeast and other microorganisms that worsen symptoms to thrive.

Intertrigo is not an infection, but it may lead to a secondary fungal infection, often caused by candida, a type of yeast. Anyone can have intertrigo, but people with a weakened immune system, diabetes or obesity are more likely to get it. It can occur on multiple areas at the same time. It doesn’t spread (unless it develops into an infection), but it occurs on parts of your body that rub together.

How to Heal Intertrigo

It’s important to keep the area clean and dry to decrease the risk of infection. “To eliminate the rash, wash the area with a mild antibacterial cleaners. Pat dry, then dab on alcohol-containing mouthwash, which kills bacteria and dissolves irritating skin oils. Finish up with an antifungal powder like Lotrimin AF Cream) to combat yeast. Do this twice a day,” recommends Dr. Corio. But remember to keep a close eye on your rash’s progress. “If these steps don’t eliminate the rash in a week or so, I suggest visiting your doctor for a stronger prescription cream.

Once you’ve gotten rid of the rash, you want to keep it from coming back. “I suggest dusting your breasts with sweat-wicking cornstarch as needed throughout the day to keep the area dry and ward off future problems,” says Dr. Corio.

Do you smell a vinegary odor?

Your chest might seem like an unlikely spot for a yeast infection, but summer’s high temperatures make the undersides of the breasts warm and damp, which creates an ideal environment for the more than 150 varieties of yeast that live on the skin. Some signs that the rash under your boob might be a yeast infection include a stale beer-like or vinegary odor, tenderness or a shiny, raised appearance. You may also experience blistering and dryness.

Paying extra attention to the rash under your boob with specific shampoo may help, says Barbara DePree, MD., a gynecologist in private practice and director of Women’s Midlife Services at Michigan’s Holland Hospital. A Certified Menopause Practitioner, she is the founder of MiddlesexMD. com, an educational resource for women’s sexual health in menopause and beyond.

How to Heal Yeast Infections on the Skin

There are many strategies you can try to heal a yeast infection under your breast. Here, the top remedies:

Dandruff Shampoo

“You should be able to clear up the rash by washing the area daily with a dandruff shampoo like Selsun Blue (Buy from Amazon, $7.48), patting it dry with a clean towel to prevent spreading and using a cotton swab or your fingers to apply an anti-fungal cream like Lotrimin (Buy from Amazon, $13.47) once a day for two weeks,” advises Dr. DePree. “It’s also a good idea to trade in any nylon bras for supportive cotton ones to prevent skin-to-skin contact and moisture buildup.”

“Once you’ve eliminated the rash, you can keep future infections at bay by washing periodically with the dandruff shampoo and applying a breast cream like Carpe No-Sweat Breast Lotion (Buy from Walmart, $30.92) to absorb moisture,” says Dr. DePree. You can also dust your breasts and bra with sweat-wicking cornstarch or apply antiperspirant to the undersides of your breasts as needed throughout the day to keep the area dry and discourage future problems. Cleansing beneath the breasts and drying skin thoroughly may also help decrease the risk of yeast growth.

Grapefruit Seed Extract

Grapefruit seed extract contains flavonoids with potent antifungal properties. Simply mix three drops of the extract with 1 ounce of almond oil as a carrier and use a cotton ball to apply the solution to your breasts twice a day for one week. Keep in mind that grapefruit seed extract is different from grapefruit essential oil or grapefruit seed oil and may cause skin irritation if applied without diluting. One option to try is the NutriBiotic Grapefruit Seed Extract (Buy on Amazon, $17.99). You should notice an improvement after two days.

Coconut Oil

Research published in Acupuncture & Electro-Therapeutics Research suggests that caprylic acid, a fatty acid found in coconut oil, may kill candida. And a study published in Biomedical and Biotechnology Research Journal found that coconut oil work may work as well as antifungal meds. Apply coconut oil to the affected area daily until symptoms subside.

Oregano Oil

Georgetown University research suggests taking one to two capsules of oregano oil, which is derived from the same herb you sprinkle over pizza, may end an infection as effectively as antiobiotic medications. Credit goes to oregano’s carvacrol, which acts as a potent yeast-killing compound. Keep in mind that oregano oil is not the same as oregano essential oil, which shouldn’t be taken orally or used internally. Oregano oil also isn’t recommended for pregnant women or people with iron deficiencies.

Keep in mind that if the rash under your boob isn’t clearing up or your symptoms are worsening, you should talk to a medical professional for a treatment plan tailored to your specific needs.

Why Your Sweat Smells Like Vinegar Under Your Breasts

“Why do my breasts smell like vinegar?” I asked my boyfriend.

My boyfriend dropped his French fry. Which, coincidentally, he had just dunked in a puddle of vinegar.

We’ve been together a year, so theoretically the romance shouldn’t be dead, but I’ve never been one for holding back when it comes to my bodily functions, something my boyfriend knows all too well by now.

If he finds me standing naked in his bedroom, I could be initiating sex, sure, but I could also be about to ask him to look at a suspicious rash I found dancing up my mons pubis.

But asking him why my breasts smelled like vinegar? That was apparently crossing some sort of line.

RELATED: What It Means When A Woman Has Uneven Breasts

If you have breasts, particularly big breasts like me, you are no stranger to the art of managing breast sweat. Sweating is normal and even healthy. See, when your body temperature rises from exercise, heat, stress or hormone shifts, sweating is what helps keep your internal temperature at a comfortable 98.6 degrees Fahrenheit.

“Sweating helps release heat, which helps maintain optimal body temperature,” says Pamela Webert, an exercise physiologist at Henry Ford Health System. “If we didn’t sweat, our bodies would literally cook from the inside out.”

So, since it was the dead heat of August, I wasn’t surprised to find that my breasts were totally saturated, but I was surprised to find that my breasts now seemed to smell like vinegar.

I did a quick internet search and found out that I wasn’t alone in wondering why my normally fragrant breasts had turned into something sour-smelling and rank.

The good news? Having breasts that smell like vinegar is totally normal. The bad news? The rest of that stank is anything but pretty.

What are the common reasons why sweat smells like vinegar under breasts?

Below, you’ll find some of the most common causes and, more importantly, what you can do to treat them.

1. Your diet includes a lot of sugar.

When it comes to your diet, eating an excessive amount of sugar can lead to the walloping case of vinegar breasts.

Seriously, though, sugar breaks down in your bloodstream. Then, it takes a new form, like a very un-sexy shapeshifter, turning into acidic compounds that can have a vinegar tang when the body produces sweat.

In fact, having sweat that smells like vinegar can be a symptom of diabetes for just this reason.

Talk to your doctor before you make any major changes to your diet, but if you eat a diet high in sugar and your breasts smell like vinegar, it could be the sugar breaking down that’s to blame.

Curse you, sugar. Curse you for being so enticing, comforting, delicious, and stank-making.

2. You sweat more.

If you smell your breasts and they smell like vinegar, it’s not actually your breast skin that is giving off this potent aroma. It’s your sweat.

When you sweat, your body is producing waste, and that waste? It stinks. If you aren’t bathing as regularly as you should be bathing, or using deodorant, this smell can build up leaving behind a vinegar-like smell.

So if your breasts smell like vinegar and it’s something you’ve only just noticed, it could be because it’s the summertime and your body is producing more sweat, especially in regions like your underboob, and that can lead to serious vinegar smells.

3. There could be an infection or common bacterial growth.

When you sweat, your body produces this not-so-sweet smelling juice through two different types of glands.

First, you have eccrine glands that basically cover your entire body. They have one job, and it’s to keep your temperature regulated. Sweat from these regions tends to evaporate immediately leaving behind little to no odor.

But the apocrine glands? Those are a sweat gland of a different color (as I seriously hope they might never say in “The Wizard of Oz”). These glands are located in your ears, your genitals, your armpits, and (you guessed it) your breasts.

These glands all perform other jobs (like producing breast milk or forming ear wax), which means that they also produce a lot of protein.

When the protein from these glands mixes with the salt from your eccrine glands, it can create a vinegar-like smell that is easy to identify and just plain rank (unless you’re into eating fish and chips).

However, it’s important to keep the area dry because if not, the excessive sweating with bacteria involved can cause serious rashes to occur. If this happens, go to a doctor and they should prescribe you an anti-fungal.

Essentially, if you find yourself asking why your breasts smell like vinegar, the TL;DR response is: because you’ve got body odor happening.

Breast sweat can be more difficult to handle than underarm stank, but there are remedies.

How can you prevent breast sweat/smell?

1. Wash your bras.

Though it’s tempting to wear a bra for many days in a row and not include it in a daily wash of your clothing, this may actually be causing an odor. 

Start by washing your bras once a week and changing them daily, especially during the hottest times of the year. Doing this can help with air circulation to keep the area dry.

2. Use aluminum-free deodorant.

Unlike your regular deodorant, aluminum-free deodorants block odor instead of blocking sweat. These deodorants contain antibacterial ingredients designed to kill odor-causing bacteria that live off your sweat protein.

Other deodorants that do contain aluminum don’t get rid of the sweat and only block your pores, which can retain the odor. Aluminum has also been linked to various diseases, so women should probably steer clear from putting it around their breasts.

3. Change your diet.

If you’re fastidious about this stuff and suspect your diet might be a factor, it’s a good idea to consult with your doctor for medical advice to find a way to balance your sugar levels and get you feeling better and your breasts smelling great.

A bonus side effect of changing your diet is that you may lose some weight in the process.

4. Wear cotton material.

Cotton is one of the most breathable fabrics out there. When you wear cotton, your skin will breathe comfortably and it can keep you cool during hot weather. 

It’s great to work out in since cotton absorbs sweat with its rope-like construction, with many nooks and crannies for the sweat to go, meaning it will stay off of you.

5. Use baby powder, corn starch, or baby wipes.

Using baby powder, corn starch, or baby wipes on your breasts is a great way to preventing chafing and rashes like intertrigo. Intertrigo commonly occurs under the breasts and can cause fungal or bacterial infection, only adding to the smell.

When in doubt, give your chest or body a wipe with baby wipes to cleanse the skin, or apply baby powder or corn starch to stop the sweat.

6. Stay on top of your hygiene.

Good hygiene is one of the most common sense ways to get rid of unwanted odor.

Wash with soap and warm water to remove all the gunk trapped within your pores. It also wouldn’t be a bad idea to exfoliate your breasts and the skin surrounding them as well. Washing often and taking care of your hygiene will stop that vinegar smell.

7. If all else fails, consider Botox.

That’s right, Botox can shut down sweat glands. A study showed that the 16 volunteers between the ages of 18-51 who were injected with Botox in the armpit had significantly lower odor intensity.  

“Botox may foster ‘favorable odorous substances’ by rebalancing the gland secretions and/or preventing unpleasant smells from skin-surface bacteria — thus improving body odor,” the lead researcher on the study said.

    What dangerous diseases changes in body odor can signal We understand what it means when sweat smells sour, sweet, dough, vinegar and even ammonia.

    August 31, 20217

    Getty Images

    We all smell differently: from adolescence, sweat has a rather specific smell, and in this case, antiperspirant is indispensable, and someone may not use it even on the hottest day. However, when the smell of sweat changes, this is a very alarming signal, writes the Express edition. Most often, such metamorphoses indicate the presence of various diseases.

    Sour smell

    The first and quite harmless reason is that you began to sweat more due to some external factors. It could be long exposure to the sun or too intense a workout. In this case, sweat mixes with bacteria that live on the skin, which is why the sour smell appears.

    A sour smell can also indicate hyperhidrosis – one of the symptoms of hyperthyroidism (thyrotoxicosis), in which too much thyroid hormone is produced. In this case, you need to contact an endocrinologist. Usually, patients in this case experience sudden weight gain and mood changes during the day.

    Another reason is too frequent consumption of spicy foods . For example, oriental spices, pepper, garlic.

    Urine odor

    Sweat begins to smell like urine due to ammonia – it is this element that gives the secretions such a specific smell. Such changes may signal liver or kidney disease . So, if these organs do not function properly, then toxins begin to be released from them, which is reflected in the smell of a person. A hepatologist will help to find out what condition the liver is in, and a nephrologist will help the kidneys.

    When sweat smells like dough

    Yeast gives a specific smell to dough, the same can be said about the changed smell of sweat. The most common “bread dough smell” appears, when you contracted STD (sexually transmitted diseases). In this case, it is better to contact a gynecologist and pass all the necessary tests.
