Heat Rash .
Heat rash is normally known as prickly heat and miliaria. Though it's common in infants, heat rash can affect adults as well. Heat rash presents itself especially during hot and humid weather. Heat rash develops when your sweat ducts commonly referred to as pores become blocked and perspiration is trapped under your skin. Symptoms range from shallow blisters to deep, red bumps. Some forms of heat rash can be extremely itchy or prickly sensation. Heat rash usually goes away on its own and can be treated by removing the worker from the heat source and allowing the body to return to a safe core temperature (MayoClinic, 2014). .
Severe forms of heat rash may need medical care, but the best way to relieve symptoms is to cool your skin and prevent sweating. Adults usually develop heat rash in folds of skin and wherever clothing causes friction. In young children, the rash is mainly found on the neck, shoulders and chest, but it can also occur in the armpits, elbow creases and groin. There are three types of miliaria, which are classified according to where the sweat ducts are blocked. Signs and symptoms for each type vary.
The mildest form of heat rash affects the sweat ducts in the topmost layer of skin. Miliaria crystallina is marked by: clear, fluid-filled blisters and bumps (papules) that break easily. The blisters that occur with miliaria crystallina are not itchy or painful. This type of heat rash usually clears on its own but can come back if hot, humid weather continues. Although miliaria crystallina is common in newborns, adults can develop it as well (MayoClinic, 2014).
Miliaria Rubra occurs deeper in the outer layer of skin or the epidermis. It is sometimes called prickly heat. Adults usually develop miliaria rubra after they're exposed to hot, humid weather or if they're confined to bed rest. Signs and symptoms typically include: red bumps, itchy or prickly feeling in the affected area, or little or no sweating in the affected areas.
