How should neonatal heat rash be treated?

The treatment of heat rash in newborns requires a comprehensive approach. The indoor temperature should be regulated to maintain a cool and well-ventilated environment, avoiding excessive heat that may cause sweat retention. Cotton, loose-fitting, breathable clothing should be selected, changed and washed frequently to keep the skin dry and清爽 (清爽 here might be better translated as "comfortable and dry"). In daily care, frequent bathing with lukewarm water is recommended, avoiding the use of irritating cleansers. After washing, gently pat the skin dry and apply an appropriate amount of talcum powder or calamine lotion to soothe and relieve itching. If symptoms are severe—for example, if pustules or secondary infections occur—prompt medical attention is necessary, and antibiotic ointments or oral medications should be used under a physician's guidance. Additionally, parents should ensure the affected areas are not excessively rubbed or scratched to prevent worsening of symptoms. With the above measures, heat rash in newborns can generally be effectively relieved and treated.
