What is a heat rash and how do I treat it?

Detailed answer

A heat rash, also known as prickly heat or miliaria, occurs when sweat gets trapped in blocked sweat glands, leading to irritation and inflammation of the skin. It commonly appears as small red bumps or blisters and is often itchy. To treat a heat rash, it is essential to keep the affected area clean and dry. Gently wash the area with mild soap and water, and pat it dry with a soft towel. Avoid using harsh soaps or scrubs that could further irritate the skin. Wearing loose, breathable clothing made of natural fibers can help prevent excessive sweating and friction. Avoid tight clothing or synthetic fabrics that can trap sweat and heat. Applying a cool compress to the affected area can provide relief and reduce inflammation. You can make a cool compress by wetting a clean cloth with cool water and gently placing it on the rash for 15-20 minutes a few times a day. Calamine lotion, available over-the-counter, can also help soothe the itchiness and irritation associated with heat rash. Apply a thin layer of calamine lotion to the affected area as directed on the packaging. If the heat rash persists or worsens despite these self-care measures, it is advisable to consult a healthcare professional for further evaluation and guidance.
