Heat rash

When your body sweats considerably for a long period of time, it can sometimes cause a rash.

What does heat rash look and feel like?

Heat rash is a red, uneven rash that normally occurs where sweat collects. The skin irritation may be accompanied by an itch or tingling pain.

Where heat rash most commonly occurs:

• Armpits
• Neck
• Groin
• Under the breasts
• In the creases of elbows and knees  

Prevent heat rash

Heat rash is most common in babies and children, and can occur in adults.

To prevent heat rash, follow these steps:

• Wear light clothing when going in the hot outdoors.
• Wear fabric that absorbs moisture well, such as cotton.
• Take breaks from being in environments where you sweat.

Be prepared for the heat

Dress children in breathable fabric. If you have to be in the heat for long periods of time, find areas where you can cool down. Bring a cloth or towel to dry sweat, and a change of clothing to replace dampened clothes.

How do you treat heat rash?

If you develop heat rash, get out of the heat and cool down. Sit near a fan and/or apply cool compresses. Dry the affected area and ensure it remains dry. Wear loose clothing to prevent the rash from being rubbed and further irritated.   

Heat illness affects everyone: you, your family, your neighbors, your customers.
