如何在最熱的天氣里保持涼爽

Wear loose clothing, mostly cotton
 
This seems obvious, but wearing clothing that is loose rather than tight allows air to flow past the skin. This carries away the warmth that your body generates and allows cooler air to flow back in. Clothes like tight jeans or a snug1 jacket trap that heat against your skin, which just makes you feel hotter. On the other hand, less fitted clothes like loose pants, a flowy shirt, or a dress all allow air to keep circulating.
 
The type of fabric2 you wear has an influence, too. When it's really hot out, materials that "breathe" -- allowing the flow of air through the fabric itself -- also work to keep you cool. Cotton and linen3 are among the most breathable fabrics4, so look for clothes made of those substances, as opposed to less permeable synthetics5.
 
Apply cold packs strategically
 
Your body regulates its temperature via a small peanut-shaped section of the brain known as the hypothalamus. This region works almost like a thermostat6 in a home, turning the temperature up or down based on various factors -- such as how cold or hot the skin is.
 
Certain parts of the skin have a larger influence than others. These areas are called pulse points. They get their name because you can feel your pulse there, and the reason you can do that is because vessels7 are so close to the edge of your skin that one can easily hear or feel the flow of blood.
 
When you want to lower your body temperature, chilling those pulse points with cold water or ice sends a signal to the brain that says, "I'm cold." This tricks your brain into turning down its thermostat. Focus on pulse points that are easy to reach: the insides of your wrists, the area around your temple, and your neck. Holding an ice pack or even a cold washcloth against the skin on these regions will make your entire body feel cooler.
 
Count your steps
 
Exercising in extreme heat is usually not recommended. That's because exercise actually heats the body up further and causes you to sweat, both of which make you feel more uncomfortable. When you're sweating more, you're also at greater risk of dehydration8. So when it's terribly hot outside, make sure you don't exercise too much.
 
Hydrate
 
Speaking of sweat, that's the best method our bodies have evolved to regulate body temperatures. Sweating helps to cool off the skin, which keeps the rest of us cool. And the human body can regulate itself far more easily when it's fully9 hydrated.
 
Proper hydration regulates blood flow, which, in turn, helps to determine the temperature of the skin. That then tells our master thermostat, the hypothalamus, how to regulate our internal temperature.
 
The sad part is that, by the time you feel thirsty, you are already dehydrated. So, to prevent dehydration and its negative effects, you should be drinking water throughout the day on a regular basis -- even before you feel thirst.
