What is Heat Rash (Prickly Heat)?

A sexually transmitted infection (STI), is brought on by the Herpes Simplex Virus (HSV).

Heat Rash, also known as Prickly Heat or Sweat Rash, is a skin condition that occurs when sweat ducts become blocked and sweat cannot escape to the skin's surface to evaporate. This blockage leads to inflammation that causes a rash. 

 

Symptoms of Heat Rash 

The primary symptom of Heat Rash is a cluster of small red bumps or blisters that often feel prickly or intensely itchy. The rash typically appears in areas of the body where skin folds over itself or where clothing causes friction, such as: 

  • Neck 
  • Chest 
  • Armpits 
  • Groin 
  • Folds of the elbows and knees 

  

Causes of Heat Rash 

Heat Rash is triggered by hot, humid weather conditions, excessive sweating, and wearing clothes that don't allow sweat to evaporate quickly. People of all ages can get Heat Rash, but it's most common in infants with less developed sweat ducts. 

 

Treatment for Heat Rash 

In most cases, Heat Rash will clear up on its own without medical treatment. However, you can try the methods listed below to stay minimise the occurrence of heat rash: 

  • Keep skin cool to avert excessive sweating 
  • Keep the affected area dry and avoid exposure to too much heat and humidity 
  • Applying cold compresses to the skin, taking cool showers, and wearing light, breathable fabrics can help 
  • Creams and sprays that contain anhydrous lanolin can also help to prevent sweat duct blockage 
  • Try to stay in the shade/away from direct sunlight during the warmest hours of the day 

 

If your condition worsens, you should see your doctor for further investigation.
