By "greenness" the researchers in this study mean how many trees, plants and shrubs are in the area, and it seems to have an effect on lung health. If you have moved from a city area to a more rural or suburban one, do you find it easier to go outside and get exercise?
Women live longer in areas with more green vegetation, according to new research funded by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health. Women with the highest levels of vegetation, or greenness, near their homes had a 12 percent lower death rate compared to women with the lowest levels of vegetation near their homes. The results were published April 14 in the journal Environmental Health Perspectives.
The researchers found the biggest differences in death rates from kidney disease, respiratory disease, and cancer. The researchers also explored how an environment with trees, shrubs, and plants might lower mortality rates. They showed that improved mental health and social engagement are the strongest factors, while increased physical activity and reduced air pollution also contribute.
