The choice of exercise time depends on everyone's unique biological clock and physical consumption. For example, a person who often works the night shift and gets off work from 2 pm to 3 pm sleeps until 1 1 2 pm every day, so his prime exercise time is 12 to 2 pm, and 5 pm to 7 pm is not suitable because of the fatigue of the previous hours, until 8 pm to 65438. . At noon, the humidity is low, but the ultraviolet ray is strong, which has advantages and disadvantages, and it is easy to cause excessive water loss and ultraviolet ray burns. But people with high humidity are especially suitable for high-intensity exercise at noon, as long as they keep the water flowing and prevent ultraviolet rays. So don't be too obsessed with what time is not suitable for sports on the Internet. The simplest example is that the old Red Army survived War of Resistance against Japanese Aggression with a high longevity rate. Do you dare to say that their great life has a time period? When they are hungry in Wan Li, they should guard against the enemy, analyze their own situation reasonably and take precautions. As long as you know, exercise is the fundamental way to prolong life and stay young forever!
