When children develop heat rash, using prickly heat powder is useful.

Heat rash in children is caused by the blockage of sweat ducts in the skin, leading to a type of skin disease. Conditions such as poor development of sweat ducts in newborns, overly hot external environments, and prolonged bed rest can make children more prone to heat rash. Once a child develops heat rash, measures to cool and dry the skin are usually effective in improving the condition. Topical medications can also be applied locally, including ingredients like calamine, prickly heat powder, etc. The principles of using topical medications are cooling, itching relief, and astringency. The components of prickly heat powder include talcum, borneol, zinc oxide, and menthol, which can help remove dampness, disperse wind, cool the skin, and relieve itching. Therefore, using prickly heat powder is useful when children develop heat rash.

(The use of medications should be carried out under the guidance of a physician)
