The heart is not a lonely organ. Nerves, hormones, electrolytes and nutrients all affect the movement of the heart. For example, parasympathetic nerve and sympathetic nerve restrict each other, regulate and maintain normal cardiac physiological function to meet the needs of internal and external environmental changes. Parasympathetic nerves reduce the self-discipline of the heart, slow down the heart rate and even lead to conduction block by releasing acetylcholine. However, sympathetic nerve enhances myocardial autonomy and excitability by releasing norepinephrine, which leads to an increase in heart rate.
To this end, "nourishing the heart" should start from the following points: First, we must have a stable mental state. Because the seven emotions will affect the normal work of the heart. Open-minded, open-minded, avoiding excessive emotions, is good for the heart.
Second, pay attention to diet. Su Wen said: "Vegetarian meat and fruits and vegetables should be fed", implying the importance of dietotherapy. Recently, it has been reported that coronary heart disease does not suddenly occur in old age. It has been confirmed that there are signs of vascular obesity since childhood. If you don't pay attention to your diet, it will gradually develop into atherosclerosis and eventually form coronary heart disease. If excessive intake of high-fat, high-calorie diet will accelerate atherosclerosis. Therefore, we should advocate vegetarianism and avoid too much meat and greasy food. Diet should be rich in vitamins, minerals, low fat, high protein and cellulose, which is of great significance to prevent coronary heart disease.
Third, we should strengthen sports activities. A British research institute believes that exercise consumes calories, which can prevent fat from depositing in blood vessels and alleviate atherosclerosis. The method is to exercise 1~2 times a day for 20 minutes each time. The amount of exercise varies from person to person, and it is best to increase the heart rate by 20 beats/min (the heart rate is increased by 20 beats/min during exercise compared with at rest). If this indicator is not reached, the effect will be minimal. On the contrary, excessive exercise is not conducive to the health of the heart.
