And you don't need to go all the way back to nature to reap the rewards.

The authors of the November 8 article, "Effect of exposure to natural environment on health inequalities: an observational population study," looked at mortality data in England and found that the disparity in health between rich and poor was double in the parts of the country with the least green space, compared to those with the most. The largest effect was seen in deaths from circulatory diseases, in part because of the opportunity--and incentive--that green spaces provide to exercise. However, they wrote, "the effect of green space is not solely based on promotion or enhancement of physical activity. Several studies have shown that contact (either by presence or visual) with green spaces can by psychologically and physiologically restorative, reducing blood pressure and stress levels and possibly promoting faster healing in patients after surgical intervention."
