Nature's positive impact on mood is easily understood on an intuitive level, but a more fine-grain analysis reveals quantifiable effects with potentially serious implications for human well-being. For this episode of BioScience Talks, we are joined by Dr. Daniel Cox of the Environment and Sustainability Institute at the University of Exeter, in Penryn, United Kingdom. Writing for BioScience, Cox and his colleagues described recent work that found strong correlations between nature exposure and positive markers of mental health. In addition, the authors used dose–response modeling to uncover threshold effects that may help guide urban planning, with the ultimate goal of reducing the societal burdens of mental illness.
