What is a Heat Rash?

A heat rash is a rash that is caused by your pores becoming clogged with sweat. It is most common during the summer months and can happen anywhere on the body. Heat rash tends to appear in places where you sweat a lot such as the stomach, underarms, legs and neck. Heat rash normally goes away without treatment, but it can cause discomfort and sometimes is confused with a poison ivy rash.

Common signs of heat rashes include: 

  • Small bumps on the skin in a cluster
  • Redness and irritation on the skin
  • Itching
  • Swelling

Heat rash creates tiny blister like bumps on the skin that are filled with sweat. They tend to be very itchy, however itching them can cause an infection. In most cases, heat rash can be treated at home with some simple care tips.

How to Prevent Heat Rash

The best way to treat heat rash is to prevent it from occurring. Heat rash may occur for young children who are over dressed for the weather, or can occur to anyone who is active outdoors in high temperatures. Simple ways to prevent heat rash this summer include: 

  • Wear loose clothing to promote air circulation 
  • Limit physical activity or other activities that make you sweat
  • Exercise during the evenings or early morning when temperatures are more mild
  • Stay in air conditioning when possible
  • Take cool showers regularly
  • Exfoliate the skin to open up the pores

Heat rash normally goes away without treatment after you cool down. As mentioned earlier, It is not life-threatening and can be managed with calamine lotion or a steroid cream to reduce the itchiness. If you notice pus, swelling, or inflammation, visit an urgent facility for further testing and treatment.
