Heat waves are prolonged periods of excessive heat, often with excessive humidity: https://www.weather.gov/safety/heat
Extreme heat makes the body work extra hard to maintain a normal temperature. Stay indoors as much as possible and limit exposure to the sun. Dress in loose-fitting, lightweight, and light-colored clothes. Avoid dark colors because they absorb the sun’s rays. Drink plenty of water, even if you don’t feel thirsty.
Check on family, friends, and neighbors who do not have air conditioning and who spend much of their time alone. Don’t forget about your pets. Share these tips from the Humane Society to keep pets safe in the heat: http://bit.ly/1RRltIL
