The importance of keeping warm

First of all, we need to know that the human body will instinctively constrict blood vessels in a cold environment, reducing heat loss on the body surface, so as to protect the temperature of vital organs in the body. As a result, blood circulation in the limbs becomes worse and the muscles become stiff. This is a big no-no for athletes, as even the slightest muscle stiffness can affect their performance.

Scientific research support

Studies have shown that wearing warm clothing can significantly improve an athlete's performance. For example, researchers at the University of East London in the United Kingdom found that swimmers wearing warm coats had an average body temperature 1.55°C higher than when wearing only swimsuits, and their core body temperature also increased. The result? Their 100-meter freestyle time improved by an average of 0.6 percent, or about 0.4 seconds faster. This is really the key to winning or losing in a competitive competition!

It's not just swimmers

Interestingly, this practice is not limited to swimmers. For example, Olympic women's high jumper Yaroslava · Mahuchik even brought a sleeping bag to the track and field to maintain her temperature.
