The heart is not a lonely organ. Nerves, hormones, electrolytes and nutrients can all affect the movement of the heart. For example, parasympathetic nerves and sympathetic nerves restrict each other, regulate and maintain normal cardiac physiological functions to meet the needs of internal and external environmental changes. Parasympathetic nerve reduces the self-discipline of the heart, slows down the heart rate and even leads to conduction block by releasing acetylcholine. However, sympathetic nerve enhances myocardial autonomy and excitability by releasing norepinephrine, resulting in faster heart rate.
To this end, "nourishing the heart" should start from the following points: first, we must have a stable mental state. Because all seven emotions will affect the normal work of the heart. Open-minded, open-minded, avoid excessive emotions, which is good for the heart.
Second, we should pay attention to diet. Su Wen said: "Vegetarian meat and fruits and vegetables should be fed up", suggesting the importance of dietotherapy. Recently, it is reported in the literature that coronary heart disease does not suddenly start in old age. It has been confirmed that there are signs of vascular adiposis from childhood. If you don't pay attention to diet, it will gradually develop into atherosclerosis over time and eventually form coronary heart disease. If you overeat a high-fat, high-calorie diet, it will accelerate atherosclerosis. Therefore, we should advocate vegetarianism and refrain from excessive 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 physical activity. A British research institution 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 make the heart rate increase by 20 times/minute (the heart rate increases by 20 times/minute during exercise than at rest). If this index is not reached, the effect will be minimal. On the contrary, excessive exercise is not conducive to the health of the heart.
