How to get rid of sweat rash

Miliaria crystallina is the most common and mildest form of heat rash. If you have miliaria crystallina, you’ll notice small clear or white bumps filled with fluid on the surface of your skin. These bumps are bubbles of sweat. The bumps often burst.

To help prevent heat rash, avoid situations that can lead to excessive sweating, such as hot, humid environments. Avoid strenuous exercise when it is very warm. In hot weather, use air conditioning, fans, and cool showers and baths to stay cool; dry your skin thoroughly; and wear lightweight, loose-fitting clothes.

Heat rash is uncomfortable, but usually harmless. It usually gets better on its own after a few days.

Sweat rash is caused by moist areas of skin rubbing together. The main causes of sweat rash include moisture, heat, lack of air circulation and friction between skin folds. Additionally, sweat, urine and faeces can make this condition worse.

Topical hydrocortisone

Topical creams that contain hydrocortisone help treat inflammation, which is why they’re good for heat rash. Hydrocortisone creams can be applied several times a day to the affected area, and most are available over-the-counter as hydrocortisone 1%.

The rash is characterized by small, raised bumps (like coarse sandpaper) spread evenly across small patches of skin. The rash usually goes away on its own and resolves in hours to a few days.

Bathe or shower in cool water with nondrying soap, then let your skin air-dry instead of toweling off. Use calamine lotion or cool compresses to calm itchy, irritated skin. Avoid using creams and ointments that contain petroleum or mineral oil, which can block pores further.

The bumps or blisters may swell, become irritated or itchy, and redden as the rash progresses. Prickly heat may spread on the body, but it is not infectious. Under normal conditions, there is no way to pass the rash on to other people.
