超实用：如何在夏天保持凉爽

Apply cold packs strategically

巧用冷敷袋

Your body regulates its temperature via a small peanut-shaped section of the brain known as the hypothalamus. This region works almost like a thermostat in a home, turning the temperature up or down based on various factors—such as how cold or hot the skin is.

人的身体通过脑部花生大小的下丘脑来调节体温。下丘脑的工作原理和家中的恒温器相似，根据不同的因素来调高或降低体温，比如说，根据皮肤温度的冷热。

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 vessels are so close to the edge of your skin that one can easily hear or feel the flow of blood.

有些特定部位的皮肤对下丘脑的影响比其他部位更显著，这些位置就是脉搏点。之所以叫脉搏点是因为在这些地方可以感受到脉搏，而且因为这里的血管和皮肤最近，人们可以轻易地听到或感触到血液的流动。

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.
