Health and longevity are the eternal pursuits of human being. The concept of longevity differs from times. Before, longevity was considered as long as one lived to the age 70 and above. But it is different now. In geriatric medicine, people who are 60 years old and above are called the elderly. The age of longevity is set at over 90 years old, which people must live to be 90 years old and above to be considered longevity. So, what’s the secret to live long and healthy life? In response to this question, Prof. Niu Lizhi gave his answer.
With the development of medicine and the improvement of living standards, the average life expectancy of human beings is also constantly increasing. However, human life span is also affected and restricted by many factors, especially various diseases that affect people's health and sometimes shorten human life span. Important factors affecting human health and life span include the following aspects:
Genetics
Genetic factors are innate factors that determine the length of life. Modern science has discovered longevity genes. Through genetic engineering and molecular biology, we can control genetic genes, especially the activity of telomerase on chromosomes, to change bad genes and make humans live longer.
Nutritional factors
Food is the most important thing for survival, whether it is malnutrition or overnutrition would easy to increase the risk of disease. A reasonable diet consists of complete nutrition, reasonable mix, appropriate proportions, no partiality, no picky eaters, no pure vegetarians, and no dietary restrictions. Keep balance between the supply of calories and the needs of the human body.
Exercise factors
Life lies in exercise, especially long-term regular aerobic exercise which is very beneficial to health and longevity. Researchers from America conducted a study samples 17,000 individuals and found that the proportion of cardiovascular and cerebrovascular diseases among people who do not into physical exercise is significantly higher than those who regularly participate in physical exercise. Their mortality rate is twice as high and their life expectancy is 4-5 years shorter. A Chinese study also found that the blood supply to the heart, brain, and lungs of the participants who have done three months of aerobic exercise were significantly greater than that those who did not exercise, and their functions were significantly improved.
Emotional factors
Mental health is much important as physical health. Research shows that people who suffer from mental trauma and depression present higher cancer and suicide rate; the incidence of depression, suicide, and cancer increases significantly after wars and natural disasters such as earthquakes. Therefore, if you want to live long in good health, you must remain open-minded and calm, learn to manage emotions, correct bad mentality in a timely manner, face various realities calmly, and do not pursue money, power, reputation, and social status excessively.
Disease factors
Nowadays, the death of most elderly people is not caused by aging. In many cases, they die from some common diseases. Relevant statistical studies show that more than 90% of people over 65 years old suffer from diseases such as hypertension, diabetes, coronary heart disease, cerebrovascular disease, and chronic obstructive pulmonary disease. Among them, more than 35% suffer from more than three diseases. It is worth noting that cancer, heart disease, and cerebrovascular disease are listed as the three major diseases that threaten human’s life.
Cancer is the result of long-term accumulation of genetic damage and changes in human cells under the long-term influence of external factors. It is a multi-factor, multi-stage, complex and progressive process. Although the occurrence of cancer is related to heredity, environment, lifestyle, etc., age is also an important risk factor among them. Especially as age increases, the risk of cancer also increases. In fact, not only cancer, but also the incidence of cardiovascular and cerebrovascular diseases, diabetes and many other chronic diseases will increase with age.
Therefore, in order to maintain health and prevent the occurrence of diseases, it is necessary to achieve a healthy diet, do regular exercise, quit smoking and limit alcohol consumption, and maintain psychological health.
✍Watch your mouth : Try not to be over-eating, always combine nutrients, eat as many type of food as you can, but in moderation, strictly quit smoking and limit alcohol consumption. Low in salt, low in fat, high in fiber, low in sugar, high in protein and high in vitamins.
✍Spread your legs : Do aerobic exercise such as walking, jogging, swimming, cycling, skipping, climbing, shuttlecock kicking, etc. It is recommended to do it once a day for more than 30 minutes each time, no less than 5 times a week, and your heart rate should be Reach submaximal heart rate during the exercise.
✍Open your heart : Tolerance and peace are morals, a noble state of human beings, and the secret to good health. Unity and harmony are not only political needs but also health needs.
