What causes prickly heat in summer and how to prevent it?

In addition to the strong sun, summer can also cause various skin diseases. Some people are more likely to get prickly heat due to their skin constitution. So what causes prickly heat? How can we prevent prickly heat?

Causes of prickly heat

Heat rash is a mild inflammation of the opening of the sweat glands on the skin. In the hot summer, sweating makes the epidermis soft, and the dirt accumulated on the skin blocks the opening of the sweat glands, causing heat rash. Heat rash infection forms heat rash virus. Symptoms: Heat rash often occurs on the scalp, forehead, neck, chest, armpits, thighs, etc. The skin first appears red spots, followed by needle-sized rashes or blisters. It feels itchy. Heat rash is initially the size of millet, and gradually forms a pus bag the size of a corn kernel or an apricot kernel. The pus bag slowly becomes soft, and finally bursts, oozing out yellow and thick pus.

Care: In summer, pay attention to indoor ventilation and cooling. Wear loose, soft, and absorbent clothes. Take a bath frequently. Wash with warm water first, then apply anti-prickly heat powder or anti-prickly heat lotion. If prickly heat recurs, take Chinese medicine to clear away heat and detoxify.
