Why does heart rate determine life span? What is the relationship between heart rate and life expectancy?

Medical research has found that excessive heart rate has various disadvantages, especially for patients with hypertension, which will greatly increase the risk of death. Slow heart rate is the "switch" of human health and longevity.

Heart rate determines the length of life.

People often say that "heart rate" refers to the number of heartbeats per minute when people are awake and quiet, which is medically called "resting heart rate". The heart rate of normal adults is usually 60- 100 beats/min, with an average of 75 beats/min.

Many studies show that if the heart rate "walks" slowly, people will live longer in the world. There is a negative correlation between heart rate and life span in mammals. When a person's heart rate is 70 beats per minute, he or she can live to 80 years old; If the heart rate slows down to 60 beats/min, you can live 13 years longer (93 years old).

This has the same rule in the animal kingdom. Take hamsters and turtles for example. Hamster's heart rate is as fast as 500 beats per minute, but its life span is only two years old. The tortoise's heart rate is as slow as 6 beats per minute, but its life span is close to 200 years old. Moreover, the total number of heart beats in a mammal's life is constant, which indirectly indicates that lowering the heart rate can prolong life.

What is the best heart rate control?

1, rapid heart rate: more than 80 beats/min.

Resting heart rate is greater than 80 beats/min, even greater than 85 beats/min, indicating that the heart rate is too fast. Always the heart rate is fast, what will happen?

Heart rate is easily disturbed by the outside world. "Smoking, drinking, drinking tea, poor sleep, mood swings, exercise, drug abuse and other factors will all affect the heart rate." If these factors are excluded and the heart rate is still high, we should be alert to the pathological heart rate increase and see a doctor as soon as possible.

Because of the high heart rate, the heart is forced to contract and relax in a short time, which will inevitably lead to the decrease of oxygen supply to the myocardium, resulting in insufficient blood supply to the heart and myocardial ischemia. At the same time, fast heart rate will also increase myocardial oxygen consumption, which will promote the occurrence of myocardial infarction, atrial fibrillation, chronic heart failure and sudden death in the long run. This isn't a reduction in life expectancy. What is it?

"If your blood pressure is high, you should pay more attention to controlling your heart rate." Increased heart rate itself is an independent risk factor for hypertension. Previous studies have shown that the incidence of hypertension increases by 8% every 10 times/minute.

Not only that, but the most crucial point is that too fast heart rate will also increase the mortality rate of hypertensive people. Every time the heart rate increases 10 beats/min, the mortality rate of cardiovascular events increases by 25%.

2, the heart rate is too slow: less than 60 beats/minute.

As mentioned earlier, a slow heart rate is good for health and longevity, but it is not enough. The slower the heart rate, the better.

Normal adult's heart rate is lower than 60 beats/min, which can be judged as bradycardia. The disadvantage is that dizziness, fatigue, chest tightness, shortness of breath and other symptoms are prone to occur at ordinary times, and syncope may occur in severe cases. These people need to be alert to systemic diseases such as influenza, hypothyroidism, hyperkalemia and depression, and investigate cardiovascular diseases.

Focus, these methods slow down your heart rate!

If we want to live a long life, we'd better control our heart rate below 75 beats per minute. The ideal heart rate of a normal person is 60-75 beats per minute. Experts say that the following ways can slow down the heart rate:

1, keep doing aerobic exercise.

Regular exercise can make the heart rate "more obedient". Sports here, with special emphasis on "aerobic exercise", include jogging, brisk walking, swimming and playing badminton. Even patients with hypertension.

During exercise, although the heart rate is accelerated, exercise can exercise the cardiopulmonary function well. The simple understanding is that it can increase the volume of the left ventricle and increase the output of each contraction. At the same systemic circulation speed, the number of beats per minute of the heart decreases correspondingly, that is, the heart rate slows down.

2. Change the unhealthy lifestyle

Mainly stay away from alcohol and tobacco; Drink less coffee and less strong tea; Lose weight, control weight; Work regularly every day and try not to stay up late; Keep a good attitude and don't be anxious; Keep the stool unobstructed, etc.
