Now that technology is more and more advanced, people also understand that it is impossible to live forever. Human life span is determined by DNA. Through the discovery of scientists, the methyl particles on each person's DNA molecule are different, and these particles determine a person's life span. # Philharmonic Health Guide #
Telomere, the factor that determines the length of life.
Through the continuous exploration and research of human mystery by scientists of all ages, it is found that there are methyl particles with different lengths on each DNA molecule in the depths of cells.
After a long period of research, it is found that every cell division will lead to the shortening of methyl particles. When it disappears, it means that the cell is about to die and there is no way to carry out mitosis.
Telomeres are located at both ends of DNA. As they get older, they become shorter and shorter. Until the end, because they are too short to split, life dies. For example, cancer cells have telomerase, which can repair telomeres, and cancer cells run rampant with telomerase.
Do people really have life and death?
Of course not. The so-called life span refers to a person's life cycle, and this length can be postponed to 1 15 years old. There are many conclusions that the life span of healthy people is about 7 times that of their own growth and development period.
The length of clinical response usually adopts average expectation, that is, calculating median expectation to infer life span, which is also the main index to measure the life span of the current population.
People's life span is influenced and restricted by many factors.
First, genetic factors account for15%; Second, the social environment accounts for10%; Third, the natural environment accounts for 7%; Fourth, medical conditions account for 8%; Fifth, lifestyle accounts for 60%!
There is only one factor that causes the difference, and there is also a huge disparity in the length of life.
Retired doctors said frankly: Longevity depends not on walking more and sleeping more, but on sticking to these two little things.
Reasonable exercise and adequate sleep are really good for your health. You might as well stick to it, which may have a great impact on delaying your life.
Good sleep quality can help the brain recover energy. People with more energy think more quickly and work more efficiently.
There are many advantages of walking: it can exercise muscles, improve the mobility of joints, strengthen bones, consume excess fat in the body, promote metabolism, promote digestion, lose weight and shape.
The retired doctor said frankly: In fact, these two little things in life are also very important to health. I hope everyone can stick to it!
1, keep an optimistic attitude
A new study by Boston University School of Medicine shows that optimistic people are more likely to live longer and live to be over 85 years old. There are about 7 1500 subjects in the study. Compared with the least optimistic people, on average, the most optimistic men and women are more likely to live to 85 years old if their life expectancy is prolonged by 1 1- 15%.
As the saying goes, "smile for ten years" means that if people keep optimistic, their bodies will remain young and healthy.
2, light diet, balanced nutrition
People who can prolong life will keep the good habit of eating lightly. Some people get sick from the mouth, mainly ignoring the focus of diet. They don't keep a regular diet, often overeat and eat irritating and indigestible foods, which will affect the health of the liver and digestive system invisibly.
People who pay attention to maintenance will provide nutrition on time for three meals, and will first understand the nature and nutritional components of food before taking it at the right time. At the same time, the combination of meat and vegetables is appropriate, and all kinds of nutrients can ensure supply and improve immunity.
These diseases are "qi", so we should pay attention to them at ordinary times.
cardiovascular disease
First of all, the most direct harm of anger is cardiovascular.
When people are furious, the secretion of adrenaline and norepinephrine increases, blood vessels contract or coronary artery spasm, and blood viscosity increases, which may easily lead to myocardial ischemia and hypoxia, thus causing angina pectoris and myocardial infarction, and even arrhythmia, and in severe cases may lead to cardiac arrest and sudden death.
Diseases of digestive system
Studies have shown that angry people are more prone to autonomic dysfunction, which will lead to decreased gastrointestinal blood volume, slow gastrointestinal peristalsis, loss of appetite, and even lead to gastric ulcer.
heart disease
Anger will increase myocardial contractility, accelerate heart rate, lead to hypoxia and increase the load on the heart. After a long time, the blood supply to the heart will not keep up, causing arrhythmia, angina pectoris and myocardial infarction.
Pay attention to regular work and rest in life, have a light and balanced diet, and keep an optimistic attitude. If you can do the above, I believe that health and longevity will come to you.
