Standing for a long time dizziness, the cause is cerebral blood supply insufficiency, caused by cerebral blood supply insufficiency have the following common conditions: First, the patient is too weak, the whole body muscles, especially the lower limbs muscle strength is insufficient, blood in standing will be too much accumulation in the lower limbs, resulting in a lack of cerebral blood supply, causing dizziness symptoms, should strengthen physical exercise, especially heel exercises, to promote the lower limbs venous reflux, restore cerebral blood supply. Second, the contraction capacity of the heart muscle is insufficient, resulting in too little blood ejection, causing cerebral blood supply insufficiency, should strengthen aerobic training, such as open and closed jump, Bobby jump, running, aerobic training can strengthen the heart and lung function, enhance the heart ejection capacity, while increasing the oxygenation concentration, restore cerebral blood supply.
