Can life expectancy be predicted? What are the indicators to measure the length of life?

With the improvement of living standards and the rapid progress of medical technology, the average life expectancy of human beings is gradually increasing, and China has reached 77.3 years old. This has developed from 40 years old in the past to 77 years old today. Humans never seem to give up, do they? Longevity The pursuit of.

From ancient times to the present, people are very concerned about the length of their life. Some people will measure their life by divination, which is not a reliable method after all. If you want to know how long you live, you can measure yourself by four medical indicators.

There are four indicators to measure the length of life, such as 1, weight.

Weight relates to people's health. Maybe when you are young, you will get fatter and fatter and feel no pain. But once you get old, the consequences of being overweight will gradually appear. Cardiovascular diseases, renal artery stenosis, diabetes and other diseases will find you one after another. According to research, obesity increases the risk of heart failure, stroke and cancer.

So how can we know if our weight is normal?

At present, the international common judgment method is to use the body mass index, and the calculation method is: body mass index = weight (kg)/[ square of height (m)]

When the body mass index

When the body mass index = 18.5~23.9, congratulations on your normal weight, please keep it up;

When the body mass index =24~27.9, it means that the body is overweight and needs proper exercise control;

When the body mass index & gt27.9 belongs to obesity, we should actively lose weight at this time.

2. waist circumference index

The waist circumference of a healthy body should not exceed 90 cm for men and 80 cm for women. 85 cm is barely acceptable. If the waist circumference of men exceeds 109 cm, the risk of death will be 50% higher than that of men with waist circumference less than 89 cm, which means that life expectancy will be reduced by 3 years after 40 years old. If a woman's waist circumference exceeds 94 cm, the risk of death will be 80% higher than that of a woman with a waist circumference less than 69 cm, which means that after 40 years old, her life expectancy will be reduced by 5 years.

3. Grip strength index

The lower the grip strength, the higher the risk of chronic diseases such as stroke and heart disease, poor health and shortened life expectancy. Every increase in grip strength 1 kg will reduce the risk of death by 3%.

Test method: keep upright, keep your feet apart naturally, hang your arms down, hold the dynamometer in your hand and try your best to hold it tightly, and then record the grip strength.

Weight value of grip strength = grip strength (kg)/ weight (kg)? 100%, when the index is greater than 50%, it means that you are in good health; if the index is less than 50%, you need to strengthen your exercise.

4. Heart rate index

The heart rate index of healthy adults should be 50~80 beats/min, and the heart rate is directly proportional to the impact of death, so maintaining a normal heart rate is helpful to prolong life.

However, the length of life is not only resigned to fate, but also can be changed through the efforts of the day after tomorrow!

How to prolong life? 1, keep a good attitude.

If you ask the elderly who live a long life the secret of their longevity, they will all mention one thing, that is, to have a good attitude.
