Getting into an air-conditioned space during extreme heat is the best way of protecting yourself against heat-related illness, Dr. Pryor says. But there are a few additional things you can do to serve the purpose.

Focus on hydrating(补水), even before you go outside

“1．,” Dr. Pryor says. And if you know you’ll be out in the heat for a while, here commends having a food or drink that contains electrolytes(电解质) — say, a salty snack or sports drink—before you head outdoors, since you’ll lose a lot of them in your sweat. Both water and electrolytes will keep you hydrated.

Go for lightweight, light-colored, and loose-fitting clothes, like a cotton shirt. Heavy, form-fitting clothing obviously won’t feel great when your skin badly needs to breathe. Meanwhile, dark-colored clothes take in the sun’s heat and make you feel hotter.

Rethink your dinner menu

Cut down on exercise needing great energy

“4．,” Dr. Pryor says. So if you typically run three miles, you might instead run one or two during a cooler time of the day, have water with you, and take breaks to check in on how your body feels.

Take a cool shower

This kind of shower has an air conditioning effect, Dr. Pryor explains. 5． . This is also an important tip to keep in mind if someone near you is dealing with a heat stroke (中暑) situation, which is the most serious heat-related illness.
