Please wear loose clothing, mostly cotton. It is obvious that wearing clothing that is loose rather than tight is welcomed in summer. . This carries away the warmth that your body produces and allows cooler air to flow back in.
. When it's really hot out, materials that “breathe” — allowing the flow of air through the fabric (衣料) itself — also work to keep you cool. Cotton and linen are among the most breathable fabrics，so look for clothes made of those substances.
Your body controls its temperature via a small peanut-shaped section of the brain known as the hypothalamus (下丘脑). . It turns 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. . 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.
When you want to lower your body temperature, cooling those pulse points with cold water or ice sends a signal to the brain that says, “Turn cold.” . 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.
