In fact, modern science provides us with four reliable indicators to predict a person's health and longevity. Shen, a professor at China Health Education Center, gave her explanation in an interview with Life Times.
Researchers at the University of Pittsburgh in the United States summarized nine studies: the speed of walking can well predict the length of life. It is found that people who walk less than 0.6 meters per second are more likely to die, and those who walk more than 1 meter per second live longer.
Why walk fast and live long? Walking is not a local exercise, it can mobilize 70% muscle groups of human body, and many systems including respiratory system, circulatory system, nervous system and musculoskeletal system will support and cooperate. On the other hand, walking slowly reflects that the human body system may be defective, which makes walking more difficult.
Walking fast is not only an indicator of the length of life, it can also help people achieve the purpose of prolonging life.
But it should be noted that "walking fast" should also be moderate. It is not that the more you walk, the faster you walk and the longer you live. Especially those with knee joint diseases, they walk fast and put more pressure on the knee joint.
Scientific exercise is effective exercise. A quick walk is not a walk, and it is only useful to walk 10 cm every step; Steps are not the way to and from work+a few steps to the toilet+a few steps up and down the stairs. What really helps to improve health is the 6000 steps completed at one time; We should also pay attention to where we walk. It is best to choose parks, grasslands and plastic sites with good air to avoid waste gas polluting roads and concrete floors.
The second indicator is the strength of both hands. Researchers from McMaster University in Canada conducted an average follow-up survey of nearly 1.4 million people aged 35-70 from 1.7 countries for 4 years. The results showed that the death risk of cardiovascular disease increased by 65438 0.7% and the death risk of non-cardiovascular disease increased by 65438 0.7% when the grip strength decreased by 5 kg.
Grip strength can well reflect the strength of the whole body. We can measure whether our physique is up to standard by grip strength index. Generally, the normal grip strength index should be greater than 50.
Calculation formula: grip strength and body mass index = grip strength (Kg) and body weight (Kg) 100.
People with weak grip can practice boxing more at ordinary times. People with good physical strength can also try to do finger lying support and push-ups with the five fingers of their hands. If you have the conditions, you can also exercise your grip strength with tools such as a grip device and dumbbells.
In Si Long-Kettering Cancer Center, the experiment of melanoma was carried out with zebrafish. The research team found that melanoma likes to stay in the place with the richest fat in fish, and they "swallow" the fat. The researchers then extracted tumor samples from the human body and found that cancer cells are also rich in fat.
In 20 16, the New England Journal of Medicine published a paper on obesity and cancer. After studying 1000 papers, it is confirmed that obesity is related to the occurrence of 13 kinds of cancers.
Fat is an essential nutrient for human body. Proper fat can maintain the stability of blood sugar and normal physiological metabolism. However, too much fat may cause a series of chronic diseases such as hypertension and hyperglycemia, and even increase the risk of cancer.
Whether the fat exceeds the standard can be calculated by calculating the body mass index (BMI), and the normal range is 18.5-23.9.
Calculation formula = weight (kg) divided by height (m2).
For example, the height 1.6m and the weight are 50kg. Substitute the formula body mass index = 50kg/1.6m 2 =19.5.
The body mass index of Chinese adult residents is about equal to 18.4, less than or equal to 18.4 is emaciation, 18.5-23.9 is normal, 24-27.9 is overweight, and 28 or more is obesity.
Controlling fat requires persistence. Professor Hu Dayi, a cardiovascular expert, said that if you want to keep fit, you must keep exercising. Exercise continuously for at least 30 minutes every day and at least five days a week. In addition, the diet structure should also be adjusted. It is suggested that the ratio of vegetarian food to meat should be at least 6 1.
The last indicator is the age of cigarettes. Respiratory department is the department most exposed to lung diseases. Wang Zhen, director of the Respiratory Department of Zhejiang Traditional Chinese Medicine Hospital, said that there are 19 doctors in this department, aged between 30 and 50, and no one smokes. He said that lung cancer is closely related to air pollution and smoking. As respiratory doctors, they know the pain of lung diseases too well, so doctors will not take the initiative to involve risk factors.
As early as 20 12, it was mentioned in the report on the health hazards of smoking in China that in the future, half of smokers will die of smoking-related diseases, and the average life expectancy of smokers will be shorter than that of non-smokers 10 years!
The damage of smoking to the lungs is irreversible, so it is better to quit smoking sooner rather than later. The doctor suggested that if you want to quit smoking, you must be willing to give up, and if you want to quit, you must completely break it; When quitting smoking, stay away from the smoking environment and all people and things related to smoking; When you are really greedy, you can eat some fruit, chew gum, drink tea and not smoke.
These are four indicators of life expectancy. Have you reached the health standard?
