It's called fitness ball. Advantages of playing fitness ball: Through palm movement, the exercise of fitness ball is completed by the cooperation of arms, wrists and fingers, which can make fingers, palms and wrists flex flexibly, promote the movement of upper limb muscles such as fingers, wrists and elbows, and prevent and correct symptoms such as numbness, trembling and decreased grip strength of upper limbs caused by degenerative diseases of the elderly. 2. The fitness ball stimulates the second and third metacarpal bones of the palm, which plays a great role in regulating the function of the central nervous system, achieving the effects of calming the nerves, strengthening the brain and improving intelligence, thus enhancing the physiological functions of internal organs and exerting the physiological effect of "moving is not bad". It may have a great rehabilitation effect on patients with neurasthenia, hypertension, asthma and influenza. As we all know, hand exercise is good for the brain. Playing fitness ball can make people concentrate, eliminate all kinds of distractions, eliminate tension and relax their brains. When playing fitness ball, the ball rotates regularly and makes a soft sound, just like sweet "music", which will undoubtedly balance the excitement and inhibition of brain nerves properly, adjust the brain properly and relax appropriately. Doing hand exercises for a long time can make the blood supply to the brain more adequate. Therefore, playing fitness balls regularly can effectively protect the brain, slow down the aging speed of the brain, avoid the occurrence of Alzheimer's disease, improve people's reaction ability and make their thinking more agile. The relationship between the hand and the brain The hand is closely related to the internal organs of the human body. As the saying goes, the hand is a barometer of the internal organs of the human body, and the hand can immediately inform the brain of the dangerous signals of visceral dysfunction by using rich nerves. The brain is the most sophisticated organ of human thinking. The brain is the hardware that produces spirit, and it is also an important part of our flesh and blood. Like other parts of the body, it needs nutrition, rest, use and reasonable medical treatment. At present, people pay far less attention to brain health care than to the prevention and treatment of physical diseases. Everyone's brain cells are about 65.438+0.45 billion at birth. After the age of 20, he began to die at a rate of 654.38+ 10,000 per day. By the age of 35, they have lost more than 500 million, and by the age of 60-70, they have lost about one tenth. This is the main reason why people feel lack of energy in middle age, but their thinking and memory decline in old age. Do you want to know how to delay the aging process of brain cells? The most effective way is to move your fingers to stimulate brain cells. After studying the relationship between the hand and the brain for many years, scientists pointed out that the most important thing for the brain is the movement of the fingers. Moving fingers to directly stimulate brain cells can increase the vitality of the brain, prevent and delay the degeneration of brain cells, which is very beneficial to brain health. The headquarters of commanders who dominate human activities and send signals is the brain. All areas of body muscle activity and motor center are called motor areas. In addition, the central sensory areas such as pain, touch, dampness and cold are called somatic sensory areas. Because there are so many sensory centers, the information received in the body, whether it is skin, joints or muscles, will be conveyed to the somatosensory area first. In addition, there are more nerve centers in the brain, and there are visual centers, auditory pathways, olfactory centers and taste centers in the brain. There are also language centers, writing centers and memory centers that specialize in expressing language, writing and memory. These central nervous systems are adjacent to each other, interrelated and stimulated each other, thus organizing a brain with developed intelligence and powerful functions. Regular hand therapy can improve brain function, relieve fatigue, improve attention and keep quick thinking. It is the best project for brain health care. Due to long-term intellectual activity, constant tension or emotional excitement, nervonic acid (a symbolic nutrient of human white matter, which is rarely synthesized by human body and needs to be supplemented in vitro, and successfully extracted from plants by Chinese scientists), which plays an important role in regulating neurotransmitters and receptors in brain cells, cannot play its normal regulating role; At the same time, too many free radicals are produced in cells, which leads to the failure of brain cells to function normally, and eventually leads to brain cell damage and even death.
