Prickly Heat Rash

Prickly heat, also known as Miliaria, is a common skin condition obtained by individuals who have been exposed from intense heat. It is often characterized with the appearance of red bumps on surfaces of the skin. Severe itching and stinging sensations can also be felt as rash appears.

This condition is often associated to heat rash since the cause and effect of prickly heat and heat rash are almost the same. However, worst cases of prickly heat can lead to formation a sunburn-like manifestation.

According to some studies, almost 30 percent of Caucasians are prone to prickly heat when they go to places with tropical climates.

Who are affected with Miliaria?

All individuals of all ages who are exposed to intense heat are possible to experience Miliaria or prickly heat. However, some people who sweat more than normal are those who are at greater risk of having prickly heat.

People who are extremely fat or obese are also prone to prickly heat since they sweat more as compared to slimmer individuals.

Babies are also at great risk to having the prickly heat skin condition because their sweat glands are not yet well developed.


The outer covering of the body called skin, contains millions of sweat glands. This glands help regulate entry and exit of heat by producing swear in order to keep the body’s optimum temperature. However if the exit points of sweat is blocked, heat is unable to get out of the body and is trapped within the layers of the skin.

As the sweat remains on the skin, it makes its way to inner layers of the skin thus causing inflammation called rash.

What are the factors that cause blockage of sweat glands?

There are several factors that can possibly cause blockage of sweat glands. The outermost layer of the skin known as Stratum corneum is made up non-keratinized dead skin cells which should be often removed when taking a bath. However if this dead skin cells remains, it can be a breeding ground for bacteria like Staphylococcus epidermis. As the bacteria stays on the surface it does not cause any harm, but the sticky substance it produces can cause blockage of pores where sweat exits.
