One of the most common forms of skin rashes is heat rash, also called miliaria [1].

Heat rash occurs when clogged pores prevent sweat from evaporating, and friction with skin results in the formation of small red bumps that are often prickly and itchy [1, 2].

The painful blisters can usually be found on the parts of the body that rub together such as the inner thighs, under the arms, necks, armpits, and elbows [2].

It can affect almost anyone but the typical victims of heat rash are babies and children whose sweat glands have not yet been fully developed, people who live in hot and humid locations, and people who are overweight and obese [2].

If you’re lucky, your heat rashes would disappear after a few days even without treatment.

For cases that are not so serious but are still itchy and painful, you can get immediate relief using these home remedies for heat rash.
