Proper exercise is helpful to health and physical fitness, but you should not exercise too hard for a long time to avoid muscle damage. You can choose the exercise that suits you according to your hobbies and physical condition. Walking is the best exercise. There must be three words: three, five and seven. "three" means that it is best to spend more than 30 minutes in three kilometers at a time; "Five" means exercising at least five times a week; "Seven" means moderate exercise, while excessive exercise is harmful. Moderate exercise is to exercise until you are old, and your heartbeat is equal to 170. Of course, besides walking, there are many sports that are very good, such as Tai Ji Chuan and ball games, which can be carried out in combination with your actual choice.
People spend most of their lives in sleep. Lack of sleep or poor sleep quality, fatigue can not be recovered, which will lead to excessive fatigue and even fatigue syndrome, reduce immune function and produce various diseases. Fatigue is the root of all diseases. A good sleep means falling asleep soon after going to bed, sleeping deeply, not waking up easily, waking up on time, not relying on alarm clock or telephone, waking up with a clear head, full of energy and no fatigue. Early to bed and early to rise is what we always advocate. Don't stay up too late, it will make your body too tired and destroy your immunity. Insomniacs can drink a cup of hot milk before going to bed to help them sleep.
