Types Of Heat Rash
Our skin is the first line of defense for us from the outside world. It is one of the primary functions of the skin to protect us from chemical exposures, infections, and harmful ultraviolet light rays. Moreover, the skin is one of the largest glands in the human body, and this largest gland regulates the body temperature by producing sweat in the body. The sweat oozing out from the surface of the skin comes from the sweat glands. The sweat glands are small glands present all over the body except in our fingers, ear canals, and toenails. The brain regulates the sweat production from the sweat glands, and these small sweat glands produce sweat that comes to the surface of the skin. The sweat ducts help in the transportation of sweat from the sweat glands to the surface of the skin. The formation of sweat is very important for the body as the evaporation of sweat from the surface of the skin helps in cooling down the body temperature.
Any dysfunction in the production of sweat can cause health problems for the affected person. In the case of heat rash, there is blockage of sweat ducts, which ultimately results in no or less sweat production. The clogged sweat ducts do not let the sweat come to the surface of the skin for evaporation and traps under the skin layers. The doctors divide the heat rashes into three different types due to the various symptoms these rashes causes. Moreover, in each other kind, the rashes affect different layers of skin. Heat rash is mainly broken down into the following three types:
Miliaria profunda or deep heat rashes:
Miliaria profunda is one of the least common types of heat rash that occurs in people. Miliaria profunda appears in the deepest skin layer, i.e., dermis, and it can become chronic with the passage of time. This type of heat rash is recurring with aggravating symptoms of redness and inflammation on the skin. Miliaria profunda causes relatively big, flesh-colored bumps on the skin. The flesh-colored bumps are usually tough-looking and are scary for the person having them. The large and firm bumps appearing on the skin might be due to the prolonged exposure to heat or due to heavy exercising.
