China's longevity statistics
Northeast China October 21st news will enter the "longevity era". In the 10 years, the elderly over 90 years of age have nearly doubled. It is found that the distribution of longevity in China shows obvious geographic clustering. Accordingly, the expert drew a map of longevity and uncovered the mystery of longevity.
centenarians are mostly in the South
according to the latest data of the national census. At present, the centenarians of our country are mostly distributed in the south, along the river basin, mainly in five regions, such as the Yangtze River Delta, the Pearl River Delta, the southeast coast, Sichuan and Chongqing, and the Central Plains. The area of the alluvial and flood plain.
the longevity of the elderly has regional clustering, suggesting that longevity is closely related to the natural environment and climatic conditions.
mild climate
the annual average temperature of these longevity areas is mostly warm, the annual rainfall is abundant, the river network is denser in most areas, the air humidity is high, and the sunshine is sufficient. These good factors constitute the specific conditions of pleasant climate and fresh air, and play a positive role in promoting the prolongation of people's life.
longevity is mostly distributed in Hilly and mountainous areas, where industry and noise are less polluted, with dense vegetation and high oxygen content in air, which is beneficial to health and longevity.
water system developed
the CDC data show that many diseases are caused by inadequate intake of water. Where there is a lot of water, people are easy to live long.
the climate is cold, it affects the life of
in the northeast and northwest regions, the winter is cold and long, the climate changes drastically, and the air is dry, so the longevity of the elderly is less.
so far, the Chinese society of Gerontology and geriatrics, identified by the Chinese Society for geriatrics and geriatrics, has more than 60 "the country of longevity" (the county and the city as the administrative unit), but none of them are in the northeast.
cold
climate is cold. The cardiovascular system of the human body is sensitive to changes in external temperature, increasing the incidence of coronary heart disease. The cold can cause the peripheral blood vessels of human body to contract, thus increasing the blood pressure and increasing the heart load, increasing the incidence of myocardial ischemia and myocardial infarction. Cold also makes people easy to catch cold and susceptible to respiratory diseases.
drought
study found that long-term living in low humidity environment can lead to a decline in human immunity. When the air humidity is less than 40%, the ciliary movement on the nasal cavity and lung mucosa slows down, and easily leads to respiratory diseases.
Hainan is a longevity island
Hainan is the country with the highest density of centenarians. According to statistics, at present, there are 1371 elderly people in Hainan and over 100 years old. In other words, Hainan has 13 centenarians per 100 thousand people. Hainan's longevity index ranks first in the country.
Longevity index is the 1000 to 90 ratio of the population aged 65 and above. It reflects the longevity level in the region.
the four major features of
1 and good sleep
A Study of the sleep status of the elderly showed that the mortality rate increased with the prolongation of sleep time (more than 30 minutes) and the decrease of sleep efficiency.
this survey shows that the average sleep time of the older people over the age of 100 years is 9.6 hours, and the sleep time of the old people of 80~99 is 8.33 hours, while the sleep time of the aged 60 to 79 years old is only 7.64 hours.
2, the number of sick times less
statistics shows that the elderly population with a high incidence of illness and hospitalization is at the age of 60~79, with the increase of age, the number of diseases and the number of hospitalization decreases, and the average age of the centenarians is less than one year. Therefore, before the age of 80, even if the physical condition is not ideal, do not be pessimistic about life long.
60~79 years old may be the age of high incidence of some geriatric diseases. In this age group, the age of the elderly is increasing, the health status of the elderly is declining, and the proportion of chronic diseases in the elderly is higher. But the elderly who have passed this period have been able to adapt to some of the adverse conditions brought by the age change, and can resist the challenges from changes in the body and external conditions, and the proportion of the disease is rapidly decreasing.
3, positive mentality
the old man's positive attitude means that they can always think of things and feel as happy as they are young; negative attitudes include tension, fear and loneliness. The proportion of the elderly with a positive mental attitude is much higher than that of the negative ones. More than half of the long-lived elderly people can always think about it when they are in trouble.
4, diet light, high proportion of vegetable
five long life of the old people, diet as a whole with light, mostly rice and flour for the main food. Vegetables are an essential part of their lives. 90% of the elderly live on vegetables every day.
