Prickly heat is a common dermatological condition caused mainly by excessively hot weather and high temperatures, which lead to excessive sweat production that cannot be properly released from the body. It often appears in individuals who are bedridden for long periods or in infants and young children. The quickest methods to eliminate prickly heat include: First, keep the skin dry and clean. It is best to ventilate the room well and avoid overheating the indoor environment. Second, wear comfortable and loose-fitting clothing to reduce the occurrence of prickly heat. Third, use talcum powder or some astringent medications, applying them to the affected areas to treat the prickly heat.
