Dress appropriately: Wear thin, light-colored, loose-fitting clothes.
Stay cool inside: If doable, stay in an air-conditioned space and take cool shower or bath.
Plan outdoor activities thoughtfully: Seek to restrict your outdoor activities to the coolest times of day, such as the morning and evening.
Wear sunscreen: Sunburn impairs your body's capacity to cool down and can dehydrate you.
Do not leave kids in vehicles: Even with a window cracked open, cars can quickly heat up to unsafe temperatures.
Stay hydrated: No matter your activity level, drink more fluids. Don't put off drinking till you're thirsty.
Keep your animals hydrated: Give your pets lots of fresh water and keep them in a shaded area.
