Everyone wants to live a long life, and there are many theories about whether a person can live a long life. We often hear long eyebrows, high foreheads, big earlobes, and palm lifelines. These signs from facial features and numerology are not scientific and cannot be fully believed; Other claims have some physiological basis, but lack universality, such as being thin, sleepy, having no life spots, having no diseases before the age of sixty, etc. Take being able to sleep as an example. Some people can sleep soundly as soon as they lie down and live a long life, but some people sleep too long and live a short life instead.
Scientists have discovered through research that the following three symptoms are indeed related to health and longevity. Interested elders can test themselves.
1. Slow heart rate. Everyone’s heart rate is different. Some people only beat 60 times a minute, while others beat 90 times. The difference is 30 times per minute, which means 40,000 times a day! The heart beats too fast, which will definitely consume too much energy, cause strain and shorten life span. The heart rate is slow, but it can ensure its normal contraction and relaxation activities, meet the blood circulation needs in the human blood vessels, and is a long-term stable, functional slow heart rate, which is directly proportional to longevity.
2. Large vital capacity The vital capacity refers to the total amount of gas that can be exhaled after one inhalation as hard as possible. Most people’s lung capacity will decline with age, but most long-lived people can maintain the lung capacity of their youth. At present, many institutions abroad have taken lung capacity as one of the first-choice items for detecting aging.
3. Strong hand grip. Researchers from the United States and the United Kingdom have found that elders with strong grip strength are not only physically strong but also function normally in various organs in the body. They also reflect that people have higher bone density and live longer.
