How to Stay Safe During a Heat Wave

During heat waves, it's essential to take precautions to protect yourself and others:

  • Stay Hydrated: Drink plenty of water throughout the day.

  • Limit Outdoor Activities: Reschedule strenuous activities to cooler parts of the day.

  • Seek Cool Environments: Stay indoors in air-conditioned spaces or visit public cooling centers.
