If you want to live longer, live around green space.
That’s the simple conclusion of the largest analysis ever performed on the relationship between the environment and human longevity—ever. Eight million people. Seven countries. One simple finding:
“When you are exposed to greenery or greenness around your home, your probability to die . . . is less compared to those with less green-ness around their home,” says David Rojas, researcher at the Barcelona Institute for Global Health and Colorado State University, and lead author of the study, which was published in The Lancet Planet Health (PDF) in collaboration with the World Health Organization.
巴塞罗那全球健康研究所和科罗拉多州立大学的研究员David Rojas是这项研究的第一作者，他说：“当你置身绿意盎然的环境中时，你的死亡概率…比家里绿色少的人更小。”这项研究是和世界卫生组织共同完成的，研究结果发表在《The Lancet Planet Health》（PDF）上。
Specifically, the research team found that for every 10% increase in vegetation that’s within 1,600 feet of your home, your probability of death drops by 4%.
Those hard numbers are the result of a large metastudy analyzing nine separate longitudinal studies about health and green space that looked at how and how long people lived over long periods of time. Subjects were from countries around the globe, too: Australia, Canada, China, Spain, Italy, Switzerland, and the U.S.
As Rojas explains, in every country, the finding was the same. People who lived near more green space lived longer than people who lived near less. This green space can be grass, trees, or gardens. It can be public or private space.
The study didn’t discriminate, nor did it have the data fidelity to claim that some plants were better for our health than others. (Satellite imagery was used to accurately measure vegetation around homes.)
