People often say "ingenuity". The heart here refers not only to the heart function, but also to the flexibility of the brain. Modern medical research has found that the flexibility of fingers is a barometer of human health. Many diseases of the elderly are characterized by numbness and trembling of hands and feet at first. If the elderly can exercise their fingers regularly, they can enhance the response ability of the nervous system and promote the health of other tissues and organs of the body.

Finger movement is a method of moving fingers, and its basic actions include rolling and stretching of a single finger, pulling fingers in the opposite direction, grasping and stretching of multiple fingers, closing and separating fingers in the palm, etc. The specific number of activities and movements can be decided by the elderly themselves, with all aspects of finger exercise as the basic requirement.

Doing finger exercise for at least half an hour every day can promote blood circulation, stimulate nerve endings and regulate nerve centers in the elderly. According to many elderly people, regular finger exercise can stabilize blood pressure, reduce blood lipid and blood sugar, and has a good preventive and improving effect on many elderly diseases.

The activities of the elderly who often take part in hands-on activities should not be too intense, while some finger exercises do not have much exercise, which is very suitable for the elderly. For example, playing musical instruments, especially stringed instruments, not only exercises the fingers of the elderly, but also exercises their reaction ability and coordination ability, which is of great benefit to the mental health of the elderly.

Another example is calligraphy, which is suitable for both movement and movement, which is very in line with the requirements of TCM health preservation. When writing, people's energy is concentrated, their fingers are moving, but their thoughts are hidden inside. This not only enhances the activities of various tissues and organs by exercising fingers, but also maintains a peaceful mind, which helps to avoid blood pressure fluctuations and improve heart function.

Besides musical instruments and calligraphy, hand-held activities such as painting, hand-knitting and table tennis can exercise fingers and contribute to the health of the elderly. Many old people like to put two balls in their palms and exercise with their fingers. The method is simple and effective, and it is also an activity that the elderly can adhere to.
