According to popular thinking, there are more people in spring than in autumn. In fact, this is in line with the laws of nature. After spring comes, the temperature warms up, and people's bodies slowly recover their vitality from winter, so they gradually increase their activity. At the same time, this season is also a good time to travel. As the saying goes, "a year's plan lies in spring", but in summer, people's desire for activities is stronger, and in autumn, the weather is getting cooler and the temperature is gradually decreasing. At this time, people's desire for activities is reduced, but in the cool season, there is no lack of going out to play and exercise. The temperature is very low in winter, which is not conducive to excessive exercise. The human body also suggests that winter is here and it's time to rest. No matter which season, we should keep a certain amount of exercise. After all, life lies in exercise, but the amount of exercise is different in each season.
