How hot is dangerously hot?
The National Weather Service has devised a Heat Index which is given in degrees Fahrenheit. The Heat Index is a measure of how hot it really feels when relative humidity is added to the actual air temperature. The National Weather Service will initiate alert procedures when the Heat Index is expected to exceed 105° F to 110° F for at least two consecutive days.
Children, elderly, and other sensitive individuals may have less ability to tolerate high temperatures. If working outside, make sure you follow the tips below on staying safe.
How can I stay safe during a heat wave?
- Strenuous activities should be reduced, eliminated, or rescheduled to the coolest time of the day.
- Drink plenty of water while the heat wave lasts. Avoid alcoholic beverages and caffeine. They interfere with your body's ability to cool itself.
- Try to get out of the heat for at least a few hours each day. If you can't do this at home drop in to a cool store, restaurant, or theater to keep your exposure time down.
Cool or at least ventilate your home; avoid enclosed rooms. Moving air, even if not cooled, helps cool you by evaporating your sweat.
