A randomized crossover study explored whether. viewing different scenes prior to a stressor altered autonomic function during the recovery from the stressor. The two scenes were (a). nature (composed of trees, grass, fields) or (b) built (composed of man-made, urban scenes lacking natural characteristics) environments. Autonomic function was assessed using noninvasive techniques. of heart rate variability; in particular, time domain analyses evaluated parasympathetic activity, using root-mean-square of successive differences (RMSSD) During stress, secondary cardiovascular markers (heart rate, systolic and diastolic blood pressure), showed significant increases from baseline which did. not differ between the two viewing conditions.. Parasympathetic activity, however was significantly higher in recovery,following,the stressor in the viewing scenes of nature condition compared to viewing scenes depicting built environments, (RMSSD 50.0 +/- 31.3 vs 34.8 +/-.14.8 ms). Thus; viewing nature, scenes prior to a stressor alters autonomic activity in the recovery period., The secondary aim was to examine autonomic function during viewing of the two scenes. Standard deviation of R-R intervals (SDRR), as change from baseline during the first 5 min of viewing nature scenes was greater than during built scenes. Overall, this suggests that nature can elicit improvements in the recovery process follwing a stressor.
