Tips for Coping With Extreme Heat
- Stay inside when possible, or find places in the shade or with air conditioning.
- Check in on your neighbors. Young children, seniors, and those with access and functional needs are the most vulnerable.
- Drink plenty of fluids, but don’t drink liquids that contain alcohol, caffeine or large amounts of sugar.
- Keep pets inside. Walk pets early in the morning, give them plenty of water and don't leave them in vehicles, which can reach dangerous temperatures within 10 minutes. For all animal emergencies, including animals left outside in extreme temperatures or in vehicles, call the Humane Rescue Alliance at (202) 723-5730.
- Wear appropriate clothing and sunscreen. Pick lightweight, loose fitting, light-colored clothing and wide brimmed hats. Use a sunscreen of SPF 15 or higher.
