How to Treat a Heat Rash

Heat rashes occur to due exposure to heat or hot environments and usually cause itchy, red rashes on the skin. Heat rash occurs as a result of dead skin cells that block the sweat glands. This causes sweat to accumulate in the gland, beneath the skin. The build-up of sweat causes the sweat glands to enlarge and swell, thus causing a skin rash.
