People who exercise regularly, that is, more than three times a week, have better physical fitness. Compared with people who don't exercise at all, people who exercise regularly are 35% less likely to die early during the study period, and only exercise once or twice on weekends, but those who meet the total exercise time are 30% less likely to die early.

In addition, regular exercise can reduce the death probability of cancer by 265,438+0% and cardiovascular disease by 465,438+0%. But exercising once or twice a week can also reduce 18% of cancer death risk and 40% of cardiovascular disease death risk. Even if the total length of exercise is not up to standard, the effect of resistance to cancer and cardiovascular disease is not much different.

Fitness precautions

It is not advisable to drink plenty of water after fitness. Don't drink water immediately after exercise, especially after strenuous exercise, and don't drink a lot of water, because drinking a lot of water will reduce the salt content in the blood, which is prone to muscle spasm and even cause headaches, vomiting and other diseases. Therefore, don't drink water immediately even if your mouth is thirsty again after exercise, and don't drink too much water at a time. In order to keep healthy, you should adopt the method of "drinking less and drinking more".

Don't lower your body temperature after fitness. After exercise, human blood vessels dilate, body temperature rises, pores dilate and perspiration increases. If you walk into an air-conditioned room immediately, or take a cold nap at the tuyere, or rinse with cold water to cool down, your skin will tighten and stop sweating, leading to physiological disorders such as body temperature regulation and decreased immune function, and causing diseases such as colds, diarrhea and asthma.
