Why can empty hand gripping improve insufficient cerebral blood supply?

Grabbing the air can improve cerebral ischemia, primarily by enhancing blood circulation through this activity.

Cerebral ischemia is mainly caused by poor blood circulation. The action of grabbing the air, involving movement of the hand joints, can improve peripheral blood circulation. If practiced regularly over a long period, this exercise may enhance overall blood circulation and reduce blood viscosity, thereby increasing blood perfusion to the heart and brain. Thus, grabbing the air may help alleviate cerebral ischemia.

However, it's important to note that while grabbing the air can serve as a daily preventive measure for cerebral ischemia, it generally cannot treat established cases. If cerebral ischemia is severe and accompanied by physical symptoms, prompt medical attention is necessary. Under a doctor's guidance, medications such as enteric-coated aspirin tablets or clopidogrel hydrogen sulfate tablets may be prescribed based on individual patient conditions. Additionally, maintain a light and easily digestible diet, avoid foods high in fat, salt, and sugar, eat meals at regular times and in moderate amounts, and avoid overeating or excessive drinking. Developing healthy lifestyle and dietary habits is essential.
