Eye rest is sufficient during sleep, but it will be affected if you lose sleep or often dream; Close your eyes and rest, but your brain is awake and your eyes rest in a relatively quiet situation, but some tissues and muscles inside your eyes are still a little active. Of course, closing your eyes is still a state of rest compared with opening your eyes. Closing your eyes is a good way to keep fit. After work or study fatigue, closing your eyes and having a rest will eliminate fatigue, restore your spirit, make people radiant and relax. In ancient China, many medical scientists regarded nourishing the spirit as a good strategy to prevent and treat diseases, preserve health and prolong life, and advocated that "preserving health depends on nourishing the spirit". The ancient medical book "Neijing" also said: "Keeping the spirit inside and being content with illness", which shows the important role of nourishing the spirit in health preservation. For many years, people have always regarded nourishing the heart as one of the measures to eliminate fatigue and keep healthy. Traditional Chinese medicine believes that God is the activity of human spirit, life, consciousness and thinking, and nourishing God is to keep the spirit, emotion and thinking indifferent and quiet. Constantly eliminating distractions, wholeheartedly, resting and closing your eyes are good ways to recuperate your spirit. As always, long-term persistence will lead to health and longevity. Modern medicine believes that people can close their eyes and rest, which can reduce 80% of the information that the brain contacts with the outside world and avoid some bad outside interference. The brain waves of EEG are in a calm state, which is conducive to maintaining the balance between the excitation and inhibition functions of the brain, so that the brain can get the best rest, thus improving the command function of the brain, making the tissues and organs of the body in the best state, strengthening the vitality and making it difficult for diseases to invade. Someone divided 1000 mice into two groups. The first group lives in a quiet state, while the second group constantly receives bad external stimuli. Other things being equal, the cancer incidence rate of the first group was 5.8%, and that of the second group was 79.6%. Close your eyes, you can do it between work and study, or you can sit alone in a quiet place, eliminate all external interference, relax your thoughts and feelings, and let your brain be in a static state, without thinking, worry and rest quietly. Obviously, closing your eyes is only a stopgap measure. It's a way to rest when you can't sleep. Its rest effect is not as good as sleep, but it can be relaxed anytime and anywhere. Therefore, whether you are tired or not, you should close your eyes for a few minutes every once in a while. This is the way to keep healthy. Of course, those who can sleep still have to sleep.
