For the first time ever, a study, published in the International Journal of Hygiene and Environmental Health, connected living near nature to a lowered risk of developing breast cancer. After analyzing data spanning markers like residential history and socio-economic levels of more than 3,600 women in Spain, researchers found those who lived closer to urban green spaces like parks or gardens were at a lower risk than those who live near agricultural areas. This suggests that land use is an important distinction for health implications.
"The mechanisms that might explain the health benefits of green spaces include higher levels of physical activity in the population and a reduction in air pollution, an environmental hazard clearly linked to the onset of cancer." —Mark Nieuwenhuijsen, PhD
According to the study authors, a handful of factors could help explain this disparity. Not only is the air cleaner near natural space, but healthy lifestyle changes could play a big role, too. "Other studies have shown that the mechanisms that might explain the health benefits of green spaces include higher levels of physical activity in the population and a reduction in air pollution, an environmental hazard clearly linked to the onset of cancer. However, we did not observe these associations," study coordinator Mark Nieuwenhuijsen, PhD, world leading expert in environmental exposure assessment, says in a press release. "We believe that other mechanisms—including lower levels of stress among people living close to green spaces—could play a role."
The study authors note more research is needed to confirm the exact factors that make living near green spaces an effective measure to decrease cancer risk. But for now, one thing is pretty clear: Moving closer to parks and other areas with clean air and stress-reducing natural features is a great way to boost your mind and your body.
