The heart is the toughest organ in the body, beating non-stop throughout one's life, at 70 beats per minute, pumping out 60 milliliters of blood each time, it beats more than 100,000 times a day, pumping out more than 6,000 liters of blood. For a 65-year-old man, his heart beats 23.4 billion times in his life, pumping out 14.2 billion liters of blood. The blood keeps flowing around the body to maintain human life. It can be seen that the maintenance of the heart is very important.
The heart is not a lonely organ, nerves, hormones, electrolytes, and nutrition can affect the heart words, such as parasympathetic and sympathetic nerves with each other, *** with the regulation and maintenance of normal cardiac physiological function, in order to adapt to the internal and external environment change needs. Parasympathetic nerves, by releasing ethylphthalylcholine, reduce cardiac autonomy, slowing the heart rate, and can even lead to conduction block. In contrast, sympathetic nerves enhance myocardial autoregulation and excitability through the release of norepinephrine, with the result that the heart rate increases.
To this end, the "heart" should start from the following points: first of all, to have a stable mental state. Because joy, anger, worry, sadness, fear and shock seven feelings will shape the normal work of the heart. Cheerful thinking, open-minded, avoid excessive joy and sadness, favorable to the heart.
Two should pay attention to diet, "Suwen" said: "vegetarian meat, fruit and vegetables, food and nutrition," suggesting that the importance of dietary therapy. Recent literature reports, coronary heart disease is not to old age only sudden onset of disease, it has been confirmed that from childhood on the visible signs of fat deposits in the blood vessels, if you do not pay attention to diet, with the passage of time, the gradual development of atherosclerosis, and finally the formation of coronary heart disease. If over-eating high-fat, high-calorie diet, will accelerate atherosclerosis. Therefore, we should advocate a vegetarian diet, abstaining from excessive meat and grease. Recipes should be rich in vitamins, minerals, low fat, high protein and fiber, etc., to prevent coronary heart disease is important.
Three to strengthen physical activity, a British research organization that exercise to consume calories, can prevent fat deposition in blood vessels, reduce atherosclerosis. The method for daily exercise 1 ~ 2 times, each 20 minutes, the amount of exercise varies from person to person, in order to exercise so that the heart rate increased 20 times / min (exercise when the heart rate is faster than the rest of the heart rate increased by 20 times / min) for the best. If you do not reach this target, the results will be very little. On the contrary, excessive exercise does not help the health of the heart.
