Stay Cool
If you are outside, especially for a long time, and the HeatRisk is red or above, you can:
- Stay in the shade as much as possible.
- Take breaks when you can.
- Do outdoor activities during the coolest parts of the day or evening, if possible.
When you are indoors, you can:
- Use fans, but only if indoor temperatures are less than 90°F. In temperatures above 90°F, a fan can increase body temperature.
- Use air conditioning or find a location that has one by dialing 2-1-1, visiting the National Center for Healthy Housing’s Cooling Centers by State page, or by contacting your local health department or emergency management agency.
Check on your family, friends, and neighbors, especially if they have chronic medical problems or live alone. Check on pets.
Stay Hydrated
Drink plenty of fluids
- Carry a water bottle. Drink and refill it throughout the day.
- Consider limiting beverages high in sugars and sodium, caffeine, and alcohol.
- Check your urine color. When it’s light yellow or clear, it usually means you are drinking enough water.
