Green space, psychological restoration, and telomere length.

摘要

In his Comment (Nov 8, p 1614), Terry Hartig explores the health-promoting properties of exposure to the natural environment, independent of socioeconomic factors. He points out that determining whether the effect is mediated through psychological restoration or increased physical activity could be difficult, in view of the paucity of data on psychological restoration compared with that for physical activity. We believe that our data on geographical variation in telomere length could contribute to answering this question.
