How did people raise their brains in ancient times?

The brain is the main nerve center of the whole body, and it is the master of thought, memory, judgment and other intellectual matters. If we want to be healthy and strong in body and mind, the brain is more important than any other part. I would like to present the following method of cultivation: Sleep takes up most of our life, and is the most important thing to preserve our internal reserves. Bathing is of immense value in relieving fatigue and refreshing the spirit, and should not be left out after any fatigue. The bowels play an important role in health, so it is advisable to pass the bowels on time once a day to reduce dizziness and other diseases. Those who do not know abstinence, brain power will be weakened, and even brain disease. When you use your brain for one hour, you should rest for ten minutes, do not continue for more than two hours. The brain nerve is originally divided into many parts, each specializing in, so it must always change the object of the outside world, so that they regulate each other, the average labor and leisure; such as watching the book is tired, change the line of study, research science is tired, change the practice of art, then the various parts of the brain nerve, can be rotated rest. When the brain is tired, it is advisable to take several deep breaths; so that the blood circulation is good and fresh, then brain fatigue can be recovered. The brain needs clean blood, so it must be supplied with fresh air. Take a walk in the open space and breathe in fresh air, and you will have endless joy and happiness in your spirit. It is advisable to perform appropriate exercise every day, because when exercising, the spirit is in a resting position. Exercise immediately after the brain, the most vulnerable to neurasthenia, so no matter how necessary diligent, not once the body is quiet for a moment after the line. Work too much, dying to sleep, it is appropriate to close the eyes to stop thinking, fake sleep for a few minutes, the spirit of a revitalization. Don’t overwork your memory, and don’t force yourself to remember things that have already happened. Before and after each meal, there must be at least 15 minutes of rest. When you eat, you should be in a happy state of mind, because happiness is the most sufficient to promote appetite. It is advisable to choose a diet that you like and is rich in nourishing materials and easy to digest, but not too much, too much blood throughout the body, day and night, gathered in the stomach to perform digestion, brain power will be reduced. Tobacco and alcohol can make the blood bad, nerve numbness, should not eat more. Recite the love of reciting poetry, listen to the love of listening to music, look at the love of pictures and carvings, love to travel to the famous garden resorts, can make the brain nerve to get a comfort. Posture is not correct, the internal organs shall not be its balance, blood stagnation, easy to feel fatigue, regardless of walking up, are appropriate to straight end flat. Nearsighted people, appropriate glasses, because the eyes are not enough people, the brain is prone to injury. It is easy to recover from fatigue by looking at green things, especially the green color of grass and trees is the best. Boredom, sadness, anger, are easy to hurt the brain. Future events, regardless of success or failure, do not need to worry too much, worrying and things do not help, but only to hurt the mind. Self-confidence is a wonderful method of health, do not keep the concept of “my brain is weak”. Everything must be optimistic, should send a big smile once or twice a day. People can enjoy themselves and their work, is also the best way to nourish the brain.
