Prepare for the heat

Watch for symptoms of heat illness, which include:

If you have any of these symptoms during extreme heat, move to a cool place and drink liquids right away. Water is best.

While waiting for help, cool the person right away by:

Stay hydrated

Drink plenty of cool liquids (especially water) before you feel thirsty to decrease your risk of dehydration (not having enough fluids in your body). Thirst is not a good indicator of dehydration.

Did you know?
Your body isn't used to extreme heat at the beginning of the summer. If you're physically active, you're also not used to extreme heat if you don't exercise regularly during hot weather.

Dress for the weather

Take a break from the heat

Keep your home cool

If your home is extremely hot

Avoid exposure to extreme heat when outdoors

Did you know?
Sunburned skin loses its sweating efficiency. This makes it harder for your body to regulate its temperature.

Never leave people or pets inside a parked vehicle or in direct sunlight.

Reschedule or plan outdoor activities during cooler parts of the day.

Avoid sun exposure. Find or bring shade when possible.
