Recommended Action

Drink plenty of water regularly, even before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration.

Limit direct sun exposure. Shade yourself by wearing a wide-brimmed, breathable hat and/or an umbrella.

Never leave people, particularly children, or pets inside a parked vehicle.

When it’s hot, eat cool, light meals. Avoid using the oven.
