Exercise can lower blood pressure, especially early mild and moderate hypertension, and lower blood pressure better, possibly through the following ways: i. Improve vasoconstriction and diastolic capacity: lower blood pressure by improving atherosclerosis, by reducing vascular resistance. Second, improve blood rheology: lower blood pressure by lowering total cholesterol, low-density cholesterol, triglycerides and other substances in the body, reducing blood viscosity and improving blood rheology. Third, enhance cardiac function: increase the heart’s output rate per beat, improve the heart’s ejection fraction, and lower blood pressure by reflexively lowering the heart rate. Enhance lung function: increase blood oxygen content to improve hypertension caused by low blood oxygen content. V. Regulate sympathetic nervous system function: relax sympathetic nerve tension, reduce work and life stress to lower blood pressure. Sixth, improve sleep: blood pressure can also be reduced after sleep improvement.
