Heat rash

Heat rash, also known as prickly heat or miliaria, is a skin condition that occurs when sweat ducts become blocked and sweat cannot get to the surface of the skin to evaporate. This causes inflammation that results in a rash. Common symptoms include red bumps on the skin, and a prickly or itchy feeling to the skin (hence the name).

Causes

Heat rash occurs when the sweat ducts become blocked. This can happen for several reasons, including:

• Wearing tight or abrasive clothing that can damage the skin.
• Using heavy creams or lotions that can block sweat ducts.
• Being in a hot, humid environment which can cause excessive sweating.
• Being bedridden or unable to move for a long period of time, which can lead to sweat pooling on the skin.

Symptoms

The symptoms of heat rash include:

• Small red bumps on the skin
• A prickly or itchy feeling on the skin
• Redness and mild swelling
• Discomfort or a feeling of heat where the rash is

Treatment

Treatment for heat rash includes:

• Cooling the skin
• Keeping the affected area dry
• Using mild soaps and avoiding skin irritants
• Avoiding hot, humid environments

Prevention

Prevention strategies for heat rash include:

• Wearing loose, lightweight clothing.
• Using air conditioning or fans to cool the skin.
• Taking cool showers or baths.
• Avoiding strenuous activity in hot, humid weather.
