Edit this passage of children's prickly heat

Also known as "sweat rash", the reason is that continuous sweating leads to sweat hole blockage. Mostly in hot and humid summer. Adults and children will happen, but because the baby's skin is tender, the sweat gland function is not fully developed, and there are more opportunities to sweat. In addition to babies, people who are sweaty or obese often suffer from sweat rash. Most rashes are self-limited and will disappear within a week or two. As long as the baby stays cool and the clothes can absorb sweat in a well-ventilated environment, or help the baby take a warm bath, put a little 3Q baby rash lotion, and then rub a proper amount of prickly heat powder to keep it dry. In the clinic, it is common for a baby to be covered with prickly heat. Parents are still afraid that the baby will catch cold and dare not blow the air conditioner or wear more clothes, which will make the rash more serious. Persistent miliaria is prone to secondary bacterial, fungal infection or eczema, so you should seek the diagnosis and treatment of dermatologists at this time. For some overweight babies, prickly heat often develops into a "scratch rash" at the parts where wrinkles rub, such as the neck, armpits and inner thighs. Skin lesions are often red, and desquamation, dampness, erosion and chapping may occur. How to avoid prickly heat or chafing rash? In hot summer, babies are actually more afraid of sultry weather than adults, so their clothes should be spacious, sweat-absorbent and breathable, and their environment should be ventilated, cool or equipped with air conditioning equipment.

After washing, gently dry it with a towel, and then apply some talcum powder or talcum powder to relieve itching. The water temperature should not be too hot or too cold when taking a bath.
