The Ultimate Guide to Treating and Preventing Heat Rash

May 15, 2023

With everyone enjoying the great outdoors during the summer, heat rash is a typical seasonal rash we all face. But there are ways to prevent this pesky skin problem! With our help, you can know how to treat and prevent heat rash and get back to having fun in the sun!

What is Heat Rash

Heat rash occurs when your pores become blocked and sweat is trapped under the skin, causing small red bumps. It’s often called “prickly heat” because of the tingling, itching sensations you might feel. While more common in infants and young children, adults are also susceptible, especially when physically active in hot and humid weather. It usually appears on the neck, shoulders, chest, and armpits, or anywhere else you may sweat a lot.

How to Treat Heat Rash

While heat rash will typically disappear after a few days once your body cools down, here are a few things you can do that might help ease the discomfort:

• Stay cool– use a cool compress or take a cold shower to relieve some of the itching and try to stay in well-circulated or air-conditioned areas.
• Try an oatmeal bath– a colloidal oatmeal bath could also help soothe itchiness and inflammation.
• Apply aloe vera gel– this is a common topical remedy for itchy and irritated skin that could provide some relief.
• Use an over-the-counter hydrocortisone cream– it’s another great topical ointment option you can apply on the itchiest areas.
• Wear loose clothing– form-fitting clothes restrict airflow and will increase friction on your skin. Make sure to dress in looser items that will wick moisture away.

While heat rash is not a serious issue, if your symptoms don’t go away after a few days and you start to feel chills, run a fever, or notice pus draining from the bumps, it’s time to call your healthcare provider.

How to Prevent Heat Rash

Most instances of heat rash can be avoided by wearing moisture-wicking clothes and keeping yourself cool. If you’re going to be outside and sweating a lot, try to remember and take breaks and seek shade whenever possible. After working out or doing another activity where you sweat a lot, shower and change into dry clothes immediately afterward to avoid clogging your pores. Also, don’t use heavy creams or moisturizers that could clog your pores as well. Stick to a thinner, gentle lotion for the warmer months.
