Creams are usually not recommended for infants with heat rash. Sweat glands are not well developed in infants, so if the outside temperature increases and humidity is too high, sweat cannot evaporate in time, which may lead to blockage of the sweat gland orifices and cause heat rash, especially in obese or overdressed infants who are susceptible to heat rash in poorly ventilated indoor environments or in hot summer conditions. If an infant develops a heat rash, it is not recommended to apply creams, as the creams may cover the sweat glands, making it more difficult for sweat, etc. to evaporate, which is not conducive to the recovery of the heat rash and has an adverse effect on the disease. Infant heat rash should be reduced as soon as possible after the environmental temperature, you can give the baby child warm bath, keep the skin clean, at the same time pay attention to give the baby to wear loose, breathable, thin, moisture-absorbent cotton clothing, but also should be diligent turn over, keep the bedroom air circulation. If necessary, apply glycerin lotion externally.
