After Harvard researchers monitored 108,630 women over eight years, they used satellite imagery to track how much seasonal vegetation they were surrounded by at home. After eight years, 8,604 of the women died. After controlling for socioeconomic status, age, race, body mass index, physical activity, smoking, education and other health and behavioral factors, they found that those with the highest amount of greenery within 250 meters of their homes were 12 percent more likely to survive than those with the lowest amount of greenery. The study’s lead author suggested that this might be because they had less air pollution, more physical activity, more social engagement and, most significantly, better mental health, as measured by a lower prevalence of depression. |
