Why do you get rash

First: different sweat excretion will produce heat rash. In the following cases, it is easy to develop heat rash: in the hot and humid season, infants and young children whose perspiration function is not perfect, fat and sweating adults or long-term bedridden patients are affected by poor perspiration excretion and pore obstruction.

Second: the formation of prickly heat is due to the high temperature and high humidity in summer. The body sweats too much and is not easy to evaporate. The sweat impregnates the cuticle of the skin, resulting in the occlusion of the sweat gland duct. After the sweat in the sweat gland duct is stored, it breaks due to the increase of internal pressure. The sweat penetrates into the surrounding tissues and causes stimulation. Herpes and papules occur at the sweat pores, resulting in prickly heat.

Third: heat rash, also known as "heat rash" and "red miliary rash", is caused by excessive sweating and poor evaporation of sweat in a high temperature and muggy environment, which leads to blockage and rupture of sweat tubes and infiltration of sweat into surrounding tissues. The main manifestations were small papules and vesicles. It is more common in children with poor perspiration regulation and long-term bedridden patients.
