Miliaria is the medical term for the heat-related skin condition where tiny, pinpoint, and pink to clear bumps form over a body area like the face or neck. It is caused when small sweat droplets are trapped in the skin due to blocked pores. 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.
Atypical or more resistant cases of heat rash may require skin culture, a microscopic exam from skin scrapings, or less commonly a skin biopsy (surgically removing a very small piece of skin using a local numbing agen. This skin is sent to a pathologist for closer examination.
First aid The first step in treating heat rash is to wash the affected area with a gentle soap (for example, Dove non-soap cleanser or something similar). Next, rinse the area with water and gently pat dry with a towel. It is recommended to wash several times a day, especially after exercise, prolonged walking, or heat exposure.
While heat rash does not lead to heat stroke, both conditions may rarely occur in the same individual. Heat rash is a very common, self-limited skin condition while heat stroke is an uncommon more serious, generalized illness. Heat stroke requires immediate medical attention. Heat stroke is particularly life-threatening in the frail, ill, and elderly. If the rash is not improving or resolving with the home treatment described or becomes worse after several days, the patient should see a physician be sure there is not a bacterial infection or other cause for the rash. If the rash is accompanied by other significant symptoms (dizziness, chest pain, shortness of breath etc.) the person should seek medical care.
Heat rash or prickly heat, is caused when the sweat glands on the skin are blocked, and then they cannot produce enough sweat to cool the skin. Symptoms of heat rash are red bumps on the skin and a itchy or prickly feeling on the skin. Heat rash treatments include OTC creams and sprays. If the sweat glands become infected, antibiotics may be necessary.
