The following is the online viewing and main content introduction of the video: put your legs on a chair or table for a few minutes, remember, your legs must be higher than your heart. When a person's legs are lifted above the heart, the blood on the feet and legs will flow back to the lungs and heart, which will not only reduce the pressure on the veins on the feet and legs, but also greatly increase the blood supply to the head and make you feel refreshed. Shaking your head when you are free also helps to improve your memory. Carotid artery is a conduit for blood supply to the brain. Shaking your head can activate these tissues, which can not only increase the blood supply to the brain, but also reduce the possibility of carotid fat deposition, which is also conducive to the prevention of hypertension and cervical spondylosis. Inadvertent stretching is also good for the brain. When the body is in a posture for a long time, a large amount of blood will be deposited in the peripheral blood vessels of upper limb muscle tissue. The process of stretching is the process of muscle tightening and relaxation. The deposited blood is washed back to the heart, and the heart gets more blood, which is also exported to all parts of the body, and the brain can get a slice of it. Good blood circulation in the head helps to improve memory and delay brain aging. Carrying a claw comb with you or combing your hair with your fingers can improve the blood supply to your scalp. The specific method is to comb the hair from front to back and from top to bottom, three or four times a day for three or five minutes each time, which can improve intelligence, nourish the heart and strengthen the brain, and is more beneficial to neurasthenia patients. Knocking teeth 50 times a day can pull the muscles of the head, promote blood circulation in the head and enhance the memory of the brain. When you knock your teeth, the secretion of saliva will also increase. Saliva contains parotid hormone, which has the effect of delaying aging. In recent years, it has been found that saliva contains anticancer components, which can effectively prevent malignant tumors in digestive tract. More fingers can stimulate the brain. Finger is the second brain of human beings, and it is connected with the most nerves. By moving your fingers, you can effectively stimulate the brain and delay the death time of brain cells. When you have nothing to do, you can stretch your fingers and bend your fingers alternately, or massage your fingertips alternately with your left and right hands, or you can always hold the fitness ball in your hand and let the two fitness balls rotate in your hand. Or mix rice and black beans, and then pick them out separately. Use these movements to exercise your hands and strengthen or maintain your brain memory. Spread your legs and drink water often. The brain consists of two hemispheres. The left brain dominates the right limb and the right brain dominates the left limb. Therefore, the activity of lower limbs can stimulate the activity of the contralateral cerebral cortex and play a role in strengthening the brain. Jogging and brisk walking for half an hour five times a week can improve your memory, although it is simple. Water accounts for 50% of the brain. Drinking water regularly can not only delay aging, but also be good for the brain. When drinking water, you should master the principle of small amount and many times. When you are thirsty, it means that your body is quite short of water.
