Allergy to Sweat: What are the symptoms and what can you do to avoid it

Allergy to Sweat

Sweating sometimes causes rashes on our body, itching, and redness of the skin.

You play sports, you are nervous about this work meeting, or you are hot because summer is approaching and suddenly your skin begins to itch, blush and make you uncomfortable, and this is where you wonder; are you allergic to your own sweat?

What is sweat allergy?

Some people see their doctor for a condition called a sweat rash. According to dermatologists, the allergy to sweat is not recognized, that is, it has no scientific basis,

but in many cases, concrete and uncomfortable symptoms occur when certain people sweat or sweat excessively.

A dandruff and itches can cause skin changes in some people. This is the case with cholinergic urticaria, and the increase in body temperature is the cause of the appearance of urticaria on the skin

These lesions appear a few minutes after you start sweating and can last up to 1 hour or more after the body has returned to normal temperature.

What are the symptoms of a sweat allergy?


  • Rashes due to excessive sweating can affect any part of the body, although they are most common on the chest and extremities. They usually itch a lot with a burning sensation.
  • Excessive sweating causes itching, redness of the skin, and even hives as if it were atopic skin, it is called cholinergic hives.
  • These rashes caused by sweating can occur anywhere on the body, the most common being the armpits, neck, and lower abdomen. They appear a few minutes after the start of sweating and usually disappear after sweating has stopped and the skin has dried, returning to its natural state.
  • Cholinergic urticaria is one of the so-called physical urticaria that is triggered during episodes of sweating, such as exercise, a hot shower, summer days or emotional stress and nerves.
  • Sometimes it is not the sweat itself that causes these symptoms, but rather an obstruction of the sweat. Sometimes the ducts of the eccrine glands (a type of sweat gland) become blocked, so that sweat is retained in the epidermis, that is, sweat cannot escape through the pores of the skin, which can cause dermatitis. The skin reacts to heat and sweat when the body temperature rises.

It should also be mentioned that people who usually suffer from atopic dermatitis, atopic skin, or who have very sensitive skin, are more likely to also suffer from the discomfort of sweating.

Treatment of sweat allergy


The most normal thing is that the irritation disappears by itself when the perspiration disappears and the body temperature returns to normal, however,

in the case of people with sensitive skin, it is recommended to use an antiperspirant. Also a good remedy is the moisturizer, which helps reduce and relieve skin rashes.

Before curing, always try to prevent as much as possible by making changes in your everyday life.

  • If you are prone to heat irritation, moisturize your skin with moisturizers. In addition, cold showers help prevent other rashes.
  • If you are a sportsman, wear one of those breathable clothes that are so fashionable now with the heat to avoid excessive sweating.
  • Certain scents or chemicals can make the situation worse. Be wary if symptoms increase with these products and try to avoid them.
