Practice also found that the vast majority of hypertensive patients, especially stage I, II hypertensive patients, after a phase of exercise therapy exercise, dizziness, headache, headache, dizziness, insomnia, palpitations and other symptoms will be reduced, or even completely disappear, while blood pressure will also appear to varying degrees of decline, so, because exercise has the following role. 1, exercise can relieve mental tension long-term nervous overstimulation or emotional excitement, the central nervous system dysfunction, resulting in the central nervous system regulation of the cardiovascular system problems, often triggering hypertension. And adhere to the exercise, can make hypertension patients emotional stability, mood, so that work and life in the tension, anxiety and excitement can be relieved. Can change the dysfunction of the cerebral cortex, central nervous system and vasomotor center, can strengthen the cerebral cortex on the regulation of the subcortical vasomotor center, so that the whole body in a state of tension of the small arteries can be diastolic, thus prompting a drop in blood pressure. 2, exercise can enhance blood circulation long-term adhere to the exercise of hypertensive patients, through the whole body muscle exercise, can make the muscle vascular fibers gradually increase thickening, coronary arteries, the increase in collateral blood vessels, increased blood flow, lumen enlargement, wall elasticity, these changes are conducive to blood pressure drop. Exercise can also produce certain chemical substances, these chemicals into the blood, can promote vasodilation, blood circulation accelerated, the well is conducive to the removal of cholesterol and other substances in the blood, so that the blood vessels to maintain the proper elasticity. Therefore, it can effectively delay the occurrence and development of atherosclerosis, to prevent the aggravation of hypertension. The principles of exercise for patients with hypertension (1) the mastery of exercise intensity The intensity of exercise can be based on the individual’s response to exercise and the degree of adaptation, the use of 3 times a week or every other day 1, or 5 times a week and other different intervals. It is generally believed that if less than 2 times a week, the effect is not obvious. If you exercise every day, the total amount of exercise should not be too large, and you should feel energetic and free of discomfort on the second day after exercise. (2) Selecting the appropriate exercise program When choosing the type of exercise therapy, different exercises should be selected according to the different stages of development of hypertension, such as walking, fast walking, jogging, swimming and medical gymnastics for patients with stage I and stage II hypertension. Patients with stage III hypertension should use body relaxation exercises, but should not do exercises or activities of high intensity, and should avoid doing head-down movements. At the same time, it should also be pointed out that when hypertensive patients are exercising, it is necessary to combine movement and stillness, and not to rush, and also exercise should be combined with medication, and medication should be reduced or gradually stopped according to the specific situation, in order to achieve certain results.
