Modern medical research has found that foods containing lecithin, cephalin and glutamic acid can improve brain activity and delay brain aging. Such foods include egg yolk, soybean, honey and foods rich in DHA(22 C 6 enoic acid), such as sardines, salmon, shellfish and mussels (also known as razor clam).
In addition, the enemy of the brain is alcohol and tobacco, because alcohol and tobacco can "poison" brain cells, lead to abnormal brain metabolism and accelerate the death of brain cells. Therefore, the first element of strengthening the brain and preventing aging must be determined to give up alcohol and tobacco!
Second, abstinence and brain-strengthening method Traditional health-keeping pays attention to "the correspondence between man and nature", requires people's lifestyle and habits to change with the seasons, and advocates moderate abstinence of sexual desire to conserve people's spirit, which is conducive to strengthening the brain and calming the nerves. If sexual life is indulgent, it will lead to mental deficiency, and even lead to insanity in severe cases. Special emphasis should be placed on "storing essence and preserving yuan" in winter, because the energy of human body is greatly reduced in winter than in summer, and it takes a lot of energy to resist the cold, which will obviously show "energy shortage", so sexual life should be stopped.
third, the method of sleeping and strengthening the brain. In real life, people with good sleep are not only energetic and clear-headed, but also full of vitality. People who have poor sleep and are troubled by insomnia often have poor energy and bad mood, and even some people suffer from neurasthenia. Therefore, if you want to keep your mind healthy, you must adjust your sleep and ensure that you have 7 to 8 hours of sleep every day.
fourth, scientific use of the brain according to the principle of "use in and discard in", people's brains should be used frequently, and the more they are used, the more flexible they will be. However, the brain should be "combined with work and rest", and the brain should not be overworked. The easiest way is to rest for 1 minutes after using the brain (studying or thinking) for one hour. There are various ways to rest, such as listening to relaxed music, overlooking the scenery or sitting still and meditating.
5. The environment for working or studying is very important for maintaining the brain. In summer, you should choose a quiet and cool environment, while in winter, you need a warm and ventilated environment, and the efficiency of studying or working will be very good. On the contrary, if you are in a sultry environment in summer (the temperature exceeds 34℃), it will not only be inefficient, but also the consumption of the brain will increase obviously, which is very harmful to the brain.
VI. Good sitting posture and brain strengthening method Scientific research has found that improper sitting posture will affect the blood supply to the brain, and slow blood flow will lead to insufficient oxygen supply to the brain, which will not only affect work efficiency, but also harm the brain nerves. The correct sitting posture is to keep your back straight, your waist straight, your head straight and your feet flat.
VII. Moderate light When the light is too strong, it will stimulate brain cells too much, and when the light is too weak and too dark, the excitement of the cerebral cortex will be suppressed, and the work efficiency will be reduced. Studying or working in moderate light is most conducive to protecting and strengthening the brain.
VIII. Meditation and exercise for strengthening the brain For the maintenance of the brain, ancient health preserving experts advocated meditation and exercise. "Meditation" is meditation. The ancients believed that when practicing meditation reached an advanced level, there would be strange effects such as "bad luck" and "nourishing the brain". American scientists trained many groups of voluntary subjects in "meditation" and found that 8% of them had improved their memory after 1 days. About 1/3 of them secreted "endorphins" (also known as happy hormones) "Exercise" can not only enhance physical fitness, but also improve mental state, making people full of confidence in life and health and longevity. The popular methods of "exercise" in China are Wuqinxi, Baduanjin, Wudang Taiyi Xianhe Gong, Wudang Taiyi Tianying Gong, Dayangong and Tai Ji Chuan, etc. The simplest methods are playing iron ball, kicking shuttlecock, climbing mountains and jogging, and even knitting is beneficial to brain health care.
