Causes of prickly heat

Prickly heat is a symptom that we often have in summer. In fact, prickly heat is a skin disease. It does not cause much harm to our body, and we also have many ways to treat prickly heat, so you don’t have to worry too much. However, we should still find out what causes prickly heat and what are the treatments for prickly heat?

Prickly heat has a lot to do with the weather. It is the hot weather that causes us to sweat too much and the sweat cannot evaporate. We cannot change the weather, but we can find ways to reduce our sweating, which is the best way to prevent prickly heat.

Prickly heat is a common superficial, inflammatory skin disease in summer or hot environments. Because in a hot and humid environment, a large amount of sweat is not easy to evaporate, causing the stratum corneum to be soaked and swollen, and the sweat gland ducts to become narrow or blocked, resulting in sweat retention and sweat infiltration into the surrounding tissues, forming papules, blisters or pustules, which are more common in the folds.

Due to the high temperature and humidity in the environment, sweating is excessive and not easy to evaporate. Sweat soaks the stratum corneum of the epidermis, causing the opening of the sweat gland duct to narrow or become blocked. After sweat is retained in the sweat gland duct, it ruptures due to increased internal pressure. The overflowing sweat penetrates and stimulates the surrounding tissues, causing papules, papulovesicles and small blisters to appear at the sweat pores. Bacterial multiplication and toxin production can aggravate the inflammatory response. Some people believe that the blockage of sweat pores is due to primary staphylococcal infection, while others believe that the occurrence of prickly heat has nothing to do with excessive sweating, but is related to the massive proliferation of micrococci on the skin surface.
