This summer, climate change continues to push Earth’s weather to extremes. 1． The short answer is yes, if you take precautions. We invite some experts to discuss the science behind exercising in the heat and offer some tips on how to exercise outdoors safely in the heat. Here are some of them.

1. 2．

Doesn’t our body need fuel to move? Yes, that’s true. A light meal is a great idea — just put an hour between eating and your workout in the heat. It takes blood and energy to digest the food, which makes more body heat — not what you want when you’re already hot. If you have had a heavy meal like a cheeseburger, you should wait two to three hours before your hot outdoor exercise, since that fat-and protein-rich meal will take even longer to move through the digestive process.

2. Protect your skin — it’s the body’s cooling system.

Your skin and the underlying tissues are incredibly designed to move warm blood away from your core to keep your vital organs cool. Damage to them prevents your body from air-conditioning itself. To protect your skin, start with sunscreen. 3．

3. Wear material that will help your body breathe.

4． Wear sweat-wicking (吸汗的) athletic clothing that allows your skin to cool. Avoid materials like cotton that basically keep the heat close to your body.

4. Drink water before, during and after exercise.

Dehydration (脱水) can really secretly attack you. 5． Make sure you drink water at least an hour before you head out to exercise. Besides, keep drinking while you’re working out. More importantly, replenish (补充) what’s lost during your workout after you finish your workout.
