From the Research
Heat rash can be effectively treated at home with simple measures, including moving to a cooler environment, removing excess clothing, and applying calamine lotion or a cooling gel like aloe vera to soothe the skin. The primary goal of treatment is to reduce inflammation, itching, and prevent further irritation. To achieve this, the following steps can be taken:
- Move to a cooler, less humid environment to reduce sweating and allow the skin to cool down.
- Remove excess clothing to improve air circulation and reduce moisture accumulation.
- Gently clean the affected area with mild soap and water, then pat dry to prevent further irritation.
- Apply calamine lotion or a cooling gel like aloe vera to soothe the skin and reduce itching.
- Over-the-counter hydrocortisone cream (1%) can be used to reduce inflammation and itching, applied in a thin layer to affected areas up to four times daily for 2-3 days, as supported by the use of topical corticosteroids for inflammatory skin conditions 2. Additionally, taking cool baths or showers and using cool, wet compresses on irritated skin can help to reduce discomfort and inflammation. It is essential to avoid using heavy creams or ointments that block pores, as they can exacerbate the condition. For comfort, antihistamines like diphenhydramine (Benadryl) can be taken following package instructions if itching is severe. Wearing loose, lightweight cotton clothing until the rash resolves can also help to improve comfort and reduce irritation. Heat rash typically occurs when sweat ducts become blocked, trapping perspiration under the skin, which leads to inflammation, redness, and the characteristic bumpy rash. Most cases clear up within 3-4 days with these treatments. If the rash worsens, shows signs of infection (increasing pain, swelling, warmth, or pus), or doesn't improve within a week, it is crucial to consult a healthcare provider for further evaluation and treatment.
