The so-called tonic is to nourish the spirit. Therefore, throughout the ages, many medical scientists regard recuperation spirit as a good way to prevent and treat diseases, maintain health and prolong life. They have always advocated that the way to preserve one's health lies in nourishing the spirit, just as Huangdi Neijing said: If you hide the spirit inside, you will be content with illness. It can be seen how important it is to raise the heart for health. As the saying goes, out of sight, out of mind. Generally, people who pay more attention to health will have this experience. After work or study fatigue, if you can close your eyes and have a rest, you will feel that your fatigue has been eliminated a lot, your spirit has recovered, and there will be an unspeakable feeling in your mind. It can be said that closing your eyes is a good way to keep fit, simple and effective. It can not only help us to get rid of other thoughts and concentrate, but also help us to enter a quiet state without thinking, so some people also call it focused maintenance. However, why do we repeatedly emphasize not to close your eyes when standing piles? In fact, there are two main reasons: first, standing with eyes closed, the body is easy to get out of control, and mental deviation is easy to occur. Our standing piles are supported by feet and don't close their eyes, so the control ability of standing posture balance is different. This is known through a simple experiment. We will keep a good balance when one foot is suspended, but as long as we close our eyes, it is difficult for most people to keep a good balance, and so is one foot. In fact, standing on two feet is the same. When standing the pile, we ask our bodies not to move. With the deepening of our psychological activities, we will have corresponding feelings. If you close your eyes at this time, you will feel good for a while, which is really conducive to a more detailed understanding. But in a short time, your body will start to tremble, and the more you experience this feeling, the greater your trembling will be. If this time is not controlled in time, there will be many negative effects, and falls are trivial. Second, standing with your eyes closed, without any contact with the outside world, has lost the original meaning of martial arts. There is no denying that standing on the stake with eyes closed is really helpful to realize the inner self, but for people engaged in martial arts training, they have nothing to do with distant goals outside, and this connection is necessary and indispensable for martial arts training. Without this connection, Wushu will lose its proper meaning. Therefore, our general requirement for standing piles is not to close your eyes, but to be blind with your eyes open. Especially in martial arts training, even if it is really necessary for health preservation, you can only close your eyes slightly, not completely, and always have some light contact with the outside world. However, we emphasize this point, not to deny the truth of keeping in good health with closed eyes. On the contrary, in sitting pile method and lying pile method, we can use the method of closing our eyes to improve the effect of exercise, especially lying pile exercise, which is very helpful to deepen our sleep and improve the quality of sleep, and is very beneficial to people with neurasthenia. For some seriously ill patients, closing our eyes can reduce their own energy consumption and achieve better exercise effect. We move laterally in bed, and the problem of body balance does not exist. Needless to say, our bodies can rely on sitting, for example, our backs are attached to the back of the chair, in short, in order to better control the balance of our bodies. Under the condition of controlling our body balance, this kind of exercise is good for practice, and the standing pile method in front will not be so violent.
