Prickly heat orsweat rash(also calledmiliaria), is anitchy rash that appears as small, raised red spots causing intense stinging or prickling sensation on the skin. It usually develops during continuous exposure to hot or humid climate. These rashes are commonly present on the body folds like neck, armpits, folds of elbow, groin and knees. However, it can occur anywhere on the body, if you are wearing tight fitting clothes that prevents air circulation and evaporation of sweat.

How does prickly heat rash develop?

There are numerous sweat glands on your skin surface. Factors that trigger development of prickly rash include excessive sweating in hot and humid climate or blockade of sweat glands. Excess sweat or trapped sweat (due to blockade of these glands) seeps into the adjacent skin surface, irritates and causes inflammation and rash. Some risk factors are:

• Excessive sweating due to exposure to hot and humid climate or strenuous excercise.
• Some people are more prone to develop prickly rash than others. It might be due to harmless bacteria thriving on skin surface that produce a sticky substance that combines with sweat and dead skin cells and blocks sweat glands
• Babies and new borns are more prone to develop prickly rash, as their sweat glands are not fully developed. Their sweat glands are narrow and easily blocked.
• Obese individuals are more prone to develop prickly rash. Skin folds in obese individuals prevent evaporation of sweat from skin surface.
• Illness and immobility can also increase risk on developing prickly rash.
• It can also develop if you wear too much of clothes preventing sufficient evaporation of sweat from surface.
