Heat Rash

 

A heat rash is simply a rash indicating that the person is too hot.  Heat rashes are common in hot and humid weather, but also in winter if the person is wearing too many layers of clothing or has a fever. Although anyone can develop heat rashes, they are particularly common in babies.

 

 

Cause
Heat rashes occur when the sweat glands on the skin’s surface become blocked. When the body gets overheated, it produces sweat to cool down; however an overproduction of sweat can clog the pores. Blockage of pores indicates that sweat is trapped underneath the skin, and the body is unable to cool down. The area becomes inflamed, resulting in a rash.

 

 

Symptoms
Heat rashes often occur in skin creases where there is not enough air circulating such as armpits, elbow creases and groin. Symptoms of heat rash vary depending upon the severity of the condition, but may include:

  • Red bumps or tiny blisters on the skin, usually in areas where clothes are tight such as the stomach, neck, bottom or forehead if you’re wearing a hat,
  • Itchiness in the affected area, and/or
  • Clear, fluid filled blisters may fill up with pus if infected.

 

 

Diagnosis
The affected area will be warm to touch, and red bumps or blisters will be visible.

 

 

Management
A heat rash is usually not serious, unless it becomes infected. There are several ways to manage a heat rash. Firstly, move to a cooler environment such as a shady area, or a room with circulating fans. Loosen or remove tight clothing. A lukewarm bath is also helpful; be sure to carefully pat dry instead of rubbing, as this can irritate the rashes. Heat rash usually goes away on its own, but seek treatment from your doctor if the rash lasts longer than 2-3 days, it becomes infected or you develop a fever.
