Secrets of Longevity: Environment, Genes and Geography

According to a study of internationalA team of scientists based on mortality data, geographic location has a significant impact on your likelihood of reaching a hundred years old. Of course, good genes play a role in life expectancy, but many environmental factors influence their work, as you know. The results suggest that residents of Washington (USA) living in areas convenient for walking are more likely to reach 100 years of age. The authors note that the work adds new evidence to the growing body of evidence that social and environmental factors make a significant contribution to longevity.

Everyone has their own secrets of longevity, but environmental factors and socio-economic status matter

Home and life expectancy

Studying life expectancy bycounties allows scientists to track geographic differences over time and evaluate contributing factors. These differences are mainly associated with a combination of socio-economic, racial-ethnic and behavioral factors, as well as health factors. In the course of work on a new study, data provided by the state on the deaths of nearly 145,000 Washington residents aged 75 years and older between 2011-2015 were examined.

Data included information on age, locationresidence at the time of death, gender, race, education and military service. In order to assign a score to various variables, taking into account the level of poverty, access to medical care, quality products, clean air, etc., based on data on the place of residence, the results of a study by the Environmental Protection Agency and other sources were also used. Based on the data obtained, it was found that a comfortable environment, the ability to walk near the house, a higher socio-economic status and a high percentage of the working-age population in the area of ​​residence are positively correlated with reaching 100 years of age.

Walking in parks makes people happy and helps to improve their health.

According to the portal Science Daily, the results of the study showed that Living in areas with mixed age populations is good for everyone. Comfortable environment, well-maintained andComfortable walking areas make exercise more accessible to older people and make it easier for them to access health care and grocery stores. The authors note that the districts in which representatives of all age groups live tend to contribute to less isolation and greater social support for older people.

Additional analysis showed that geographicdistricts with a high probability of reaching one hundred years of age are located in metropolitan areas and small towns with high socio-economic status, including Seattle and Pulman.
Authors of a study published in the journalThe International Journal of Environmental Research suggests that more research will be needed for more extensive findings. At the same time, scientists hope that ultimately their work will form the basis for creating healthier communities that will help increase the duration and quality of life of older people.

What are the blue zones of the planet?

For the first time, the geographical concept of the Blue Zone(Blue zone) was described by an American traveler Dan Buttner in the article "Secrets of a Long Life" in 2005, for the magazine National Geographic. Today, the blue zone is the territory with the highest longevity in the world. There are five such zones in the world and all of them have a number of common characteristics. The most famous blue zone on Earth is located on the island of Sardinia in the Mediterranean Sea, which is part of Italy as an autonomous region of Sardinia. More than 22 people over 100 live there. The island is dominated by dry subtropical(Mediterranean) climate, the average temperature in January is 7-10 ° C, in July 24-26 ° C. Scientists are looking for scientific justification for the phenomenon of life expectancy on the island for decades.

The Greek island of Ikaria looks like this

According to USA Today, according to earlierResearch, the city of Seoul in Sardinia, in which the largest number and increase in long-livers, is remote from the rest of the world and has a small gene pool. However, the reason genes allow islanders to live so long remains unknown. It is noteworthy that documented and verified data on centenarians in Seoul appeared in the 19th century.

Other blue zones of the planet include JapaneseOkinawa island, whose inhabitants consume a lot of vegetables and a little meat, and also perform physical exercises daily; Ikari island in Greece, which has the largest percentage of residents over 90 years old; Nicoya Peninsula, Costa Rica, the secret of longevity in which locals consider the consumption of vegetables and fruits, especially oranges; Loma Linda, California, USA, home to a large Seventh-day Adventist community. They refused cigarettes, alcohol, coffee and fatty foods. What factors do you think contribute to longevity? We will wait for the answer here!
