Causes of Underboob Rash
A rash under the breast can occur for various reasons. Here are some general causes of underboob rashes:Excessive Sweat
The primary cause of underboob rash is excessive sweating. This can be due to high heat and wearing ill-fitting clothes against the breasts. Other factors, such as obesity and humid climates, can also cause a rash under your breasts.Hormonal Changes
Apart from sweating, hormonal changes can also result in rashes under your breasts, particularly during your pregnancy.Heat Rash
Skin-on-skin rubbing and red skin cause a heat rash under your breast. This occurs when your sweat gland gets blocked. It may also happen when you sweat more than usual. Sitting in an air-conditioned space and taking a cool bath can reduce heat rash to some extent.Diabetes
Diabetes patients are also affected by underboob rashes. Their affected areas may have swelling, redness, and a moist appearance. It can also lead to severe infections later.Infections
Bacterial, yeast, and fungal infections can also occur under your breasts. Painful breasts, along with other symptoms like fever, vomiting, cold, fatigue, and chills, are indicative of infection. These are easily treatable with standard medication.How to Prevent Underboob Rashes?

Use Cotton
Reducing the amount of sweat around your breast area is the best method to deal with underboob rashes. You can place a thin piece of cotton between the skin and the lower part of your breasts to absorb moisture easily. Moreover, you can wear cotton bras made from lightweight, moisture-wicking fabric. This keeps the underboob area dry throughout the day.Go Braless
High moisture levels will irritate your skin. To avoid underboob rashes, it is necessary to allow air circulation around your breasts. If you develop severe red rashes, you can go braless for a few days.Proper Care
You can use an unscented soap to wash under your breasts when showering. Proper cleansing helps prevent further infections and underboob rashes.Wear Loose-fitting Clothes
Wear comfortable clothes, such as loungewear or t-shirts, that won’t irritate your skin. It’s better to avoid tight-fitting outfits when you have rashes under your breasts.Avoid Scented Products
Scented soap can cause pain, itchiness, and rashes. You can use unscented varieties with less harsh ingredients when choosing lotions, soaps, and other cleaning products.How Do You Treat Underboob Rashes?
