How many days does it take for adults to recover from heat rash?

The recovery time for adults with heat rash varies depending on the severity of the condition. Generally, if the symptoms are mild, with effective treatment and proper care—such as keeping the skin clean and dry, regulating indoor temperature, and wearing loose, breathable clothing—the rash may improve within approximately 7 days. However, for patients with more severe symptoms, such as pus discharge or skin lesions, the recovery period may be prolonged to about 10 days or even longer. To accelerate recovery, patients may use topical medications as directed by a physician, such as calamine lotion or talcum powder, for local treatment. If itching is significant, oral antihistamines, such as cetirizine hydrochloride tablets or loratadine tablets, may be taken to relieve the itching. Additionally, maintaining good indoor air circulation and avoiding prolonged exposure to hot and humid environments are important measures to promote recovery from heat rash.
