Heat rash usually clears up in about a week.
Heat rash usually occurs during the summer months when there is high heat and humidity. This is the time when the body sweats a lot. When the sweat does not pass out of the body smoothly, but builds up in the stratum corneum or deeper layers of the body, a lot of clear blisters will appear.
As far as possible, you can choose to control the temperature of the environment to keep it cool and dry, the secretion of sweat will be reduced, the blockage of sweat glands caused by sweat secretion will be relieved, and it can usually be cured in about a week.
However, if the heat rash recovers, it enters the hot environment again or secretes more sweat. At the same time, clothes are not changed often enough, which will make it easy to develop heat rash again. It will take a long time to recover. It is important to pay more attention to skin hygiene and take baths regularly to avoid untimely sweat discharge, which may cause sweat blockage.
If the symptoms of heat rash are serious, it is recommended to consult the dermatology department of the hospital in time.
