Prickly heat, also known as corn rash, is a superficial, inflammatory skin disease commonly seen in summer or hot environments. The cause of the disease is related to high temperature and sultriness, blockage of sweat ducts, and bacterial reproduction.
In a hot and stuffy environment, a large amount of sweat is not easy to evaporate, so that the stratum corneum is impregnated and swollen, resulting in narrowing or blocking of the sweat ducts, stagnation of sweat in the sweat ducts, increased pressure, rupture of the sweat ducts, and extravasation of sweat into the surrounding tissues and lead to disease. In addition, the proliferation of bacteria on the surface of the skin produces toxins, which also aggravates the inflammatory response and leads to prickly heat.
If the weather is hot patients with prickly heat, should be ventilated to dissipate heat, loose and breathable clothing, keep the skin clean and dry, and promptly go to a professional hospital, actively cooperate with the doctor for treatment.
