It pays to know the difference between heat exhaustion and heat stroke when temperatures get past 105.
Heat exhaustion: Excessive sweating, feeling faint, and muscle cramps. Get to somewhere air conditioned, a store, your house, your car. Drink cool water and put a cool compress on your head.
Heat Stroke: When you stop sweating and feel nauseated, develop a headache or fever, and/or become lightheaded. Call 9-1-1 immediately.
Either condition can start with a rapid pulse. If your heartrate starts climbing, better to be safe than sorry. Get to a cooler area and seek treatment if needed.
