Nature can get it out of your mind: The rumination reducing effects of contact with nature and the mediating role of awe and mood

Evidence has been found that contact with nature may reduce rumination in healthy individuals living in urban environments. This paper aims at i) testing whether one may replicate previous findings using a shorter duration of nature exposure, and ii) explore the possibility that a shift in attention away from self (notably induced by the emotion of awe), leading to mood restoration, may mediate such nature-rumination relationship. We showed that a walk as short as 30-min in an urban park significantly reduced ruminative thinking in healthy participants, whereas a 30-min walk along a city transect devoid from natural elements did not. Also, we showed that the “walk in nature” significantly reduced negative mood and elicited more awe and more externally oriented thoughts than the “walk in city”. Our mediation analysis did not show any direct effect of contact with nature on rumination levels. Instead, it showed that the more awe participants experienced while walking, the more negative affect was reduced, which then lead to reduced rumination. Also, our mediation analysis showed that nature can affect rumination via mood improvement only and irrespective of awe. This study adds to previous research supporting the so-called “psychological ecosystem services” and calls for additional efforts aimed at exploring the extent to, and mechanism(s), by which contact with nature may affect rumination, notably in clinical populations.
