Prickly Heat

Prickly heat, also known as miliaria, is a type of skin rash caused by sweat ducts becoming blocked and trapping sweat beneath the skin's surface. It is most commonly seen during the summer months when the skin is exposed to high temperatures. The rash is characterised by small red bumps, which may be itchy or uncomfortable. In severe cases, the bumps may become filled with a yellowish fluid. Prickly heat is caused by the obstruction of sweat ducts, which normally allow sweat to evaporate off the skin's surface. Blockage can occur due to a combination of factors such as thick clothing, excessive sweating, and occlusive ointments. Heat can also play a role, as the sweat ducts become more vulnerable to blockage in hot and humid environments. The most effective treatment for prickly heat is to reduce the body temperature and create a cooler environment. The application of cool compresses and the use of air conditioning can help to reduce the temperature of the skin, while avoiding tight clothes and occlusive ointments can also help to prevent further blockage of sweat ducts. In some cases, topical steroid creams may be prescribed to reduce the itchiness and inflammation.
