Heat Disorders Learn the symptoms of heat disorders and know how to give first aid. Heat can kill by pushing the human body beyond its limits. Under normal conditions, the body's internal thermostat produces perspiration that evaporates and cools the body. However, in extreme heat and high humidity, evaporation is slowed and the body must work extra hard to maintain a normal temperature. The following are possible results of extreme heat.
Sunburn Symptoms: Skin redness and pain, possible swelling, blisters, fever, headaches. First Aid: Take a shower, using soap, to remove oils that may block pores preventing the body from cooling naturally. If blisters occur, apply dry, sterile dressings and get medical attention.
Heat Cramps Symptoms: Painful spasms usually in leg and abdominal muscles. Heavy sweating. First Aid: Firm pressure on cramping muscles or gentle massage to relieve spasm. Give sips of water. If nausea occurs, discontinue.
Heat Exhaustion Symptoms: Heavy sweating, weakness, skin cold, pale and clammy. Weak pulse. Normal temperature possible. Fainting, vomiting. First Aid: Get victim to lie down in a cool place.
