The length of life, the heartbeat knows? A study of 2 million people found that the speed of heartbeat is related to the length of life
Have you heard the saying that "a person's heart beats 2.5 billion times in a lifetime, and whoever finishes the jump first will go first"?
This implies that the speed of the heartbeat has an impact on lifespan. The relationship between the number of heartbeats and lifespan has been confirmed in nature:
- A tortoise has a heartbeat of 6 beats per minute and a lifespan of 277 years;
- Sea turtles/whales are also animals with a slow heart rate and a very long life.
For humans, does the speed of the heartbeat affect life expectancy? Is there any scientific basis for this statement?
1. Which one has a longer life expectancy between a heartbeat of 60 and a heartbeat of 100 per minute?
Some people say that the slower the heartbeat, the longer the life expectancy. Is there any scientific basis for this statement? Yang Jingang, deputy chief physician of the Cardiology Department of Fuwai Hospital of the Chinese Academy of Medical Sciences, said that it is actually correct to reverse this sentence - people with a faster heart rate have a shorter life span.
Under normal circumstances, a person's heart rate should be maintained at 60 to 100 beats per minute, and it is normal to keep the heart rate within this range .
So if the heartbeat is too fast and exceeds the normal range, what effect will it have on the body? Professor Wen Qibang, a professor at China Medical University, has conducted research on this. Since 1994, he has collected nearly 2 million health examination data for analysis.
It was found that within the healthy heart rate range, people with different heartbeats had different life expectancy .
① People with a heart rate of 60-70 beats per minute, every time the heart rate increases, the life expectancy may be shortened by about 4 months;
②Compared with people with a heart rate of less than 60 beats per minute, people with a heart rate of 70-80 beats per minute have an average life expectancy shortened by 3 years;
③ People whose heart rate is kept at 80-90 beats per minute have an average life expectancy shortened by 5 years;
④ People whose heart rate is maintained at 90-100 beats per minute have an average life expectancy shortened by 8 years;
⑤The life expectancy of people with a heart rate above 100 beats/min may be shortened by 13 years.
It is not difficult to see through research that within the normal range, people with higher heart rate per minute have shorter life expectancy . But we can't let the heart rate be too slow. Once the heart rate is lower than 60 beats per minute, it belongs to the category of bradycardia.
If the heart rate continues to drop below 50 beats per minute, the output of the heart will be reduced, and then the blood supply to various organs will be insufficient, which will easily induce functional disorders .
2. Doing 4 things often may be depleting the life of the heart
The speed of the heart rate is directly related to the health of the body. Many people have tachycardia in life. Long-term tachycardia is not good for health.
Rapid heartbeat will keep the heart running at high speed for a long time, and it needs to complete contraction and relaxation in a short period of time, which can easily induce myocardial oxygen supply reduction, induce myocardial ischemia, and easily cause heart enlargement and heart failure.
When the body suffers from diseases such as hyperthyroidism, infection, heart failure, hypertension, myocarditis, and acute myocardial infarction, tachycardia may be induced.
In addition to pathological reasons, some daily bad behaviors can also lead to a faster heartbeat.
1. Lack of sleep
Long-term lack of sleep can easily induce tachycardia and also have adverse effects on other organs. It is recommended to keep a sleep time of about 8 hours a day.
2. Obesity
Obese people often have problems with high blood pressure, blood lipids, and blood sugar. Being obese for a long time can easily induce tachycardia. After losing weight, not only can the heartbeat return to normal, but also various indicators will gradually recover.
3. Lack of exercise
People who exercise regularly have a lower resting heart rate than those who do not exercise, because exercise can help exercise heart muscle function.
4. Drink a lot of strong tea and coffee
Drinking a lot of tea, coffee and other beverages will lead to excessive intake of caffeine and other ingredients in the body, which in turn will cause rapid heart rate, and may also cause palpitation and hand shaking.
3. How to stabilize the "beating" heart? 5 things that matter
So, for some people with tachycardia, how to lower their heart rate? Do these few things well.
- keep exercising
Insisting on exercising can help exercise the heart muscle and lower the heart rate, and different age groups are suitable for different exercises.
Middle-aged and elderly people can properly perform relatively soothing exercises such as walking, Tai Chi, and Baduanjin, while young people can perform relatively high-intensity exercises such as running and aerobics. Note that exercise must be done according to one's ability, and you should not force yourself.
- enough rest
Sufficient sleep is very important to health. Sleep is the best "charger" for people. You should pay attention not to stay up late every day. It is best to keep about 8 hours of sleep every day.
- balanced diet
Eat more fresh fruits and vegetables, lean meat, nuts, beans and fish in your diet. These foods are rich in nutrients and can help lower blood pressure and make your heart beat easier. Pay attention to eating less high-fat and high-calorie foods to avoid obesity.
- emotionally stable
Pay attention to maintaining emotional stability, and don’t let yourself be in a state of excessive pressure for a long time. When you feel a lot of pressure, you should pay attention to relieve it in time. You can find someone to talk to or go out for a walk. More outdoor activities are helpful for relieving stress. It helps a lot.
- regular physical examination
Many tachycardias are discovered during routine physical examinations, and patients feel that they have no obvious symptoms of discomfort. Regular physical examination can help to detect abnormalities in the body in time, so as to achieve early detection and early treatment.
There is no doubt that the heart rate has an impact on health. In daily life, it is recommended that everyone maintain good living habits and try to keep the heart rate in the normal range as much as possible.
