heat rash : Heat Rash Types (Miliaria)

Miliaria is the medical term for the heat related skin condition where tiny, pinpoint, pink to clear bumps form over a body area like the face or neck. It is caused when small sweat particles are trapped in the skin. This trapping of sweat may cause inflammation and itching around the sweat pores. Miliaria is very common in infants but may also occur in adults. This condition occurs especially after repeated episodes of sweating in a hot, humid environment. Miliaria may look like small clear blisters or like gooseflesh.

There are four types of miliaria:

1. clear (miliaria crystalline),
   
2. white/yellow (miliaria pustulosa),
   
3. red (miliaria rubra),
   
4. deep (miliaria profunda).
