What you need to do:


  • Keep your body temperature cool to avoid heat-related illness.
  • Stay in air-conditioned buildings as much as possible.
  • Find an air-conditioned shelter.
  • Do not rely on a fan as your primary cooling device.
  • Avoid direct sunlight.
  • Wear lightweight, light-colored clothing.
  • Take cool showers or baths.
  • Check on those most at-risk twice a day.


  • Because your body loses fluids through sweat, you can become dehydrated during times of extreme heat.
  • Drink more water than usual.
  • Don’t wait until you’re thirsty to drink more fluids.
  • Drink from two to four cups of water every hour while working or exercising outside.
  • Avoid alcohol or liquids containing high amounts of sugar.
  • Remind others to drink enough water.
  • Also, extreme heat for a long period of time may put a strain on the electric grid. To reduce strain to the grid during the peak hours of 3 p.m. to 7 p.m., it's recommended that AC is set to 78°F or warmer and avoid using large appliances.


Stay updated on local weather forecasts so you can plan activities safely when it’s hot outside.
