Some babies do develop severe eczema after being exposed to heat, which is directly related to the baby’s current poor body resistance, parents overdressing him or her, and possibly an allergy to clothing that comes into close contact, which parents can look for based on common causes. If they are not sure, they can take their baby for an allergen test. If the baby is not very serious, you can apply moisturizer and weak glucocorticoid ointment for external application, which can have a clear treatment effect on eczema. However, parents should pay attention to the baby’s eczema when it is hot, must exclude whether it is prickly heat, because clinically some children can appear prickly heat in the skin folds and other areas after the heat.
