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.

Ask a health professional, such as a pharmacist or physician, how medications or health conditions can affect your risk in the heat.

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