Prickly Heat Prevention

Prickly heat, medically known as miliaria rubra, is a rash that occurs when sweat glands become blocked and results in irritation to the skin. Sweat allows the body to cool and, when not working correctly, the body overheats. Trapped sweat creates bumps, blisters and an itchy rash. Infants and obese adults are prone to prickly heat, and the rash occurs normally in hot, humid climates. Prickly heat is preventable by following certain guidelines.

Prevention

• Avoid hot humid conditions by staying in an air-conditioned setting. Hot, humid weather stimulates the sweat glands, and sweat blockage results in higher body heat. High body temperature may result in heat stroke, which is a serious medical condition characterized by symptoms of weakness, thirst and dizziness, according to Healthline.com. Seek medical help immediately if someone you know has these symptoms.

  Exercise inside an air-conditioned area or during the morning or evening, avoiding the hottest time of the day. Take care of outside chores during the cooler parts of the day and wait until gardens or flower beds are shaded to work in them. If no shade is provided, work during the cool parts of the day.

  Wear loose-fitting clothing, as tight clothes rub against skin stimulating the sweat glands. Wear cotton--it is lighter and less irritating than heavier fabrics. Remove sweat-covered clothing as soon as possible as the clothing may irritate the skin, promoting prickly heat.

  Take baths or showers twice a day during the summer or when air is hot and humid. Clean skin breathes easier, lowering the risk of clogged sweat glands. If a bath or shower is not possible, wet a towel with cool water and lay against your hot skin. Cooling the skin is the best way to avoid prickly heat.

  Apply baby powder to areas of the body that tends to get heat rashes. Baby powder cools skin and keeps irritation at a minimum.

  Drink plenty of water to keep from becoming dehydrated. If you need to be in the sun, wear a high-SPF sunscreen and a hat. Take breaks to stand in the shade or inside air-conditioned buildings.

  Prickly heat may lead to a more serious health condition such as heat stroke, so it is wise to try and prevent this medical condition from occurring.
