Newswise — During the long hot days of summer, it's possible for the body's natural cooling mechanism to be overwhelmed. Symptoms of heat exhaustion often begin suddenly and may include faintness, rapid heartbeat, low blood pressure, cold and clammy skin, nausea and, in fair-skinned people, an ashen appearance. The August issue of Mayo Clinic Health Letter recommends these steps if you suspect someone is experiencing heat exhaustion. Make sure the person:
* Gets out of the heat, preferably into an air-conditioned place
* Lies down with legs elevated slightly
* Loosens or removes most clothing
* Drinks cold water or a sports drink to replenish fluids
If there's no improvement after these steps are taken, get the person to a doctor. Heat exhaustion can quickly evolve into the more dangerous heatstroke. If signs of heatstroke develop -- the two key signs being a fever of 105 F or higher and hot, dry skin -- seek emergency medical help.
