Prickly heat, also referred to as a heat rash or miliaria, occurs in hot, humid conditions. Symptoms of prickly heat include large areas of reddened skin or a rash. The rash associated with prickly heat varies and may include small, clear blisters, red bumps or flesh colored raised bumps. The rash may itch and occurs due to clogged sweat ducts. Newborns and individuals participating in physical activities during hot, humid weather are most at risk for developing the condition, according to the Mayo Clinic.
Cool Environment
Moving from hot, humid conditions to a cool environment will help treat prickly heat. An air-conditioned room or a cool room with fans can help reduce sweating. This may be the only treatment necessary for mild cases of prickly heat. Individuals with prickly heat need to dress in loose, lightweight cotton clothing to remain cool.
Topical Treatments
Applying powders, creams and powders to the skin can help decrease the symptoms associated with prickly heat. Powders, such as talcum or baby power, can help keep the skin dry and comfort the affected individual. Calamine lotion can help decrease the itching. Topical steroids may decrease the reaction in the skin, such as redness, but will not help cool the skin. Lanolin smoothed on the skin can help prevent blocked sweat ducts and can reduce the possibility of new lesions forming on the skin, according to the Mayo Clinic.
Oral Antibiotics
Prickly heat rashes can itch and become bothersome. After scratching at the skin, sores can form. Bacteria or dirt from under the fingernails may transfer to the open sores during scratching. After introducing bacteria into the wound, an infection may occur. Oral antibiotics can help treat skin infections.
Avoid Irritants
Individuals need to avoid products and conditions that aggravate the prickly heat. The condition will generally go away in about a week unless additional irritation occurs to the affected skin. People suffering from prickly heat need to avoid wearing tight clothes that can cause irritation to the skin. After bathing with mild soap, individuals need to air dry and avoid toweling off. Some creams, lotions and ointments can further block sweat glands and pores. These products can also help hold heat in the skin. This blockage can continue to aggravate and worsen the condition.
