Insufficient blood supply to the brain can be improved with proper exercise. Insufficient blood supply to the brain can be seen as a result of atherosclerosis, which leads to poor vascular elasticity and slowed blood flow. Some cerebral hypoperfusion is also due to low blood pressure and inadequate cerebral perfusion. It can also be seen as cerebral hypoperfusion due to hyperglycemia and blood viscosity. For atherosclerosis, hypotension and hyperglycemia caused by insufficient blood supply to the brain, can be reduced through exercise to reduce the degree of cerebral vascular atherosclerosis, but also delay the occurrence of cerebral atherosclerosis, to improve the cerebral blood supply deficiency has a certain effect. Low blood pressure will increase after physical exercise, which will have an improved effect on the patient’s cerebral perfusion. Exercise can lower the patient’s blood sugar, which can reduce the blood stickiness caused by high blood sugar, so the cerebral blood supply deficiency can be improved by exercise.
