Tips to Stay Safe

- Stay hydrated and stock up on clean drinking water to get you through multiple days of heat.
- Reschedule outdoor activities for cooler times of the day, and take breaks in the shade or air conditioning.
- Cover windows with curtains or shades, or use window reflectors designed to reflect heat back outside.
- Check on friends, family, and neighbors, especially those who do not have air conditioning or spend much of their time alone.
