How to Treat Heat Rash

　　Mosquitoes are abundant in summer, and the relatively high temperatures during this season cause increased sweating, making skin conditions more common than in other seasons. Eczema and miliaria (heat rash) are among the most frequent summer-related dermatoses. So, how should miliaria be treated?

　How to Treat Miliaria

　　Once a prickling or stinging sensation develops, it is essential to improve ventilation and cooling within the living environment. Clothing should be loose-fitting and breathable. The skin can be gently wiped with a lukewarm, clean, damp towel to maintain surface cleanliness and dryness. Topical treatments should follow the principles of cooling, astringency, and itch relief. Calamine-mint lotion may be applied and gently massaged into affected areas—or calamine powder may be dusted onto the skin—to provide cooling, heat dissipation, and promote resolution of miliaria. If suppuration occurs—for example, in cases of pustular miliaria—topical application of fish oil ointment, calamine lotion, or coptis powder may be used for their antibacterial and anti-inflammatory effects.

　　Upon onset of miliaria, prompt action is crucial. First, move away from the hot environment; then apply calamine lotion or miliaria powder topically. In cases of purulent inflammation or secondary infection, topical antibacterial agents such as Bactroban® ointment (mupirocin) or compound sodium iodide ointment may be used. Severe cases often require adjunctive oral antibiotic therapy. For intense pruritus, oral antihistamines—including cetirizine hydrochloride dispersible tablets, loratadine tablets, or chlorpheniramine maleate—may be prescribed. Patients with miliaria must avoid cold-water bathing, as this may trigger excessive sweating and even worsen the condition.

　　Avoid smoking and alcohol consumption; maintain regular sleep patterns and avoid staying up late. Ensure a balanced diet incorporating both lean meats and vegetables to support nutritional equilibrium, and engage regularly in outdoor physical activity.
