Prickly heat in newborn babies can be eliminated through daily care and, if necessary, medication. Prickly heat occurs in hot and stuffy environments, and newborn babies are more prone to prickly heat as their sweat ducts are not fully developed. When prickly heat occurs in newborn babies, first of all, we should pay attention to lowering the environmental temperature, indoor ventilation, give babies frequent baths, change clothes, wear loose, lightweight, breathable and sweat-absorbent cotton clothes, pay attention to soothe the baby’s emotions, and try to avoid babies from scratching the lesions, which may aggravate the condition. In addition, you can apply prickly heat powder to the baby after bathing, but pay attention to the right amount to avoid excessive blockage of pores and sweat glands. If the condition is serious, it is necessary to go to a regular hospital in a timely manner, under the guidance of specialists to use hydrocortisone solution and other drugs for treatment.
