Dr. Michael Smith: In the sweltering days of summer, over exertion can lead to life threatening heat stroke. New guidelines released by the National Athletic Trainers Association. commend that anyone with heat stroke should be cooled off before they are taken to a hospital. According to Douglas Casa, lead author of the report and head of the Korey Stringer Institute, it’s vital to cool a heat stroke victim within 30 minutes of onset. Heat stroke is the leading cause of death in sports during the summer. It occurs when the body’s temperature is so high, 104 degrees or above, that it starts to shut down. Symptoms include headache or nausea, acting confused, agitated, passing out, or having seizures. The key is to be prepared. Immersing the patient in ice water is the best treatment. But if you don’t have access to a large enough container of water, move the person to a shady area,or fan them while applying whatever cold water or ice you can find over the whole body. If you or your kids are not used to hot weather, take care if you’re going to be outside and exerting yourself, whether it’s for sports, play, or work. Start slowly, take frequent breaks, and drink plenty of fluids. Better to avoid heat stroke than to have to treat it. For WebMD, I’m Dr. Michael Smith.
