If people want to live a long and healthy life, they must adapt to the natural environment, including seasons and climate. Nature is a necessary condition for people to survive, and people can't live without nature. To maintain normal life activities, we must adapt to it. Otherwise, you will get sick and shorten your life. In nature, the four seasons change in spring, summer, autumn and winter, resulting in cold, hot, dry and wet, thus affecting all things in nature. Therefore, exercise must also pay full attention to the unity with the natural environment. With the change of seasonal climate, we should make corresponding adjustments in the method, content, time and quantity of exercise. Only in this way can we achieve the purpose of fitness.

Spring, winter goes to spring, everything recovers, flourishes and shows great vitality. In this season, it is advisable to get up early and go outdoors. Long-distance running is still a suitable sport. In early spring, winter exercise can still be continued. As the temperature rises gradually, the exercise should also make adaptive changes. In spring, the climate is changeable, sometimes cold and sometimes hot. Pay attention to clothes before and after exercise, and it is not appropriate to reduce clothes at first. Change sweaty underwear in time after exercise to prevent colds.

In summer, the weather is hot and the temperature rises. Due to the stimulation of heat, a series of changes will take place in human physiological activities. In the meantime, you should pay attention to avoid exercising in strong sunlight. Exercise time and amount of exercise can be reduced appropriately. Long-distance running, football and other events can be temporarily suspended. Pay attention to prevent heatstroke during exercise, and drink boiled water with salt in moderation after exercise. Swimming is the most suitable event in summer, but it is best to arrange it before 10 in the morning and after 4 pm.

In autumn, it begins to cool down slowly in the morning and evening. At this time, we should insist on going to bed early and getting up early. Morning and evening are good opportunities for exercise, and all sports can be carried out in this season (including swimming). With the deep cold in autumn, you can gradually increase the time and amount of exercise. After the Millennium Festival, the cold gets worse in the morning and evening. Try to avoid nudity during exercise to prevent the cold from invading the body.

Winter is the coldest season among the four seasons, and it is the season when everything hides. At this time, exercise should overcome the cold with tenacious will, continue to adhere to outdoor sports and never stop. Do enough warm-up activities before exercise to make joints and muscles not stiff. Long-distance running, ice and snow sports and football are all suitable sports. Exercise for a long time and exercise a lot. But to prevent frostbite, change underwear in time when sweating after exercise. Exercise in the morning should not be too early, and it is best to do it after the sun comes out.

The reason why we should pay attention to the changes of the four seasons in sports and fitness is to emphasize that the human body should adapt to the changes of the yin and yang of the four seasons according to the theory of health preservation in the motherland, and we should not only achieve the purpose of strengthening the body, but also avoid the invasion of external evils in sports, so as to achieve the purpose of improving health.
