First of all, happy running, happy running overdraws his yang in advance. Running is a great sport. Modern people have no time to run during the day, because they are busy with work and can't get up in the morning. Instead, they exercise at night. At night, your body should rest. If you run at this time, your pores are open and moisture will enter.
Night is the time to nourish yin. Fun running consumes yin and body fluid, resulting in insufficient body fluid. Body fluid is transformed through hard work, that is, it consumes hard work. During the day, hard work is tiring. I still go running at night, and the essence of my internal organs is consumed by my limbs. But excessive physical exertion can lead to emaciation and even sudden death.
Others walk as much as possible every day, which will damage their knees. Our knee joint began to decline slowly after the age of 30. Knee joint often has short-term pain. When we are 40-50 years old, after a long walk or strenuous exercise, there will be obvious pain in the knee joint, which reminds us to pay attention to maintenance. After 50 years old, patellar cartilage basically reaches its service life. Especially for middle-aged and elderly people, walking, climbing and running do great harm to their knees, so these behaviors should be relatively reduced.
