The natural context of wellbeing: Ecological momentary assessment of the influence of nature and daylight on affect and stress for individuals with depression levels varying from none to clinical.

This paper explores how everyday encounters with two natural phenomena -natural elements and daylight- influence affect and stress levels for people differing in mental health. Nature and daylight exposure both have well-documented beneficial effects on mental health and affect but to what extent their exposure has beneficial effects in daily life is currently under investigated, as is the question whether lower mental health would make one more, or instead, less responsive. To this end, an ecological momentary assessment protocol was employed for a period of 6 days. Fifty-nine participants varying in level of depressive symptoms from none to clinical completed momentary assessments of affect, stress, and their physical environment. Results indicate beneficial effects of nature and daylight on affect and some effects on stress and stress-related outcomes. For nature exposure, but not for daylight exposure, effects were stronger for those in higher need of restoration, stressing the importance of our everyday environment for mental wellbeing.
