How to Get Rid of Heat Rash on Face Overnight?


Since many of our users have asked our doctors the question, “how to get rid of a heat rash on face overnight”, we’ve decided to write an article about the subject.  A heat rash occurs because of blocked sweat glands or hair follicles. The trapped sweat is what causes the raised rash that is seen.  The rash is caused by exposure to hot environments. Where clothing causes friction on the skin is typically where the rash appears.

Generally, there are three different types of rashes that can form. They each look a little different:

  • Clear rash. This is mild and the bumps are not itchy or painful.
  • Red rash. This is an itchy rash with a red bump.
  • Deep rash. Flesh colored bumps. These form after many episodes of heat rash.

Usually, a heat rash does not need medical attention. Therefore, you can treat the rash at home. But, if the rash is severe, or limits what you can do, you should see your doctor be sure it is a heat rash.

Facial Heat Rash Treatments

Commonly, patients ask how to get rid of a facial heat rash overnight. Usually, the heat rash will go away by itself once the trapped sweat is able to leave the body. Therefore, the most important part of treatment is avoiding overheating.

This will remove anything on the skin blocking the sweat glands. Then, let your skin air dry. Lastly, the skin will need to be cooled. This can be as simple as staying in an air-conditioned room. So air can circulate, wear loose clothing around the rash. Overall, the heat rash should go away quickly by just cooling the skin.
