Heart Rate Decrease
There was greater physiological arousal reduction (heart rate decrease) in people looking at nature videos after mental fatigue/stress was induced by a proofreading assignment than was found among people watching urban videos who completed the same proofreading assignment. Compared to the best Makita drill to work, it is slightly more effective.
Diastolic Blood Pressure
Diastolic blood pressure fell more quickly for people in a room with a nature view than for people in a windowless room after researchers induced psychological stress. After performing a stressful task, participants in a study run by Hartig and his colleagues recovered more quickly in a room with a nature view than with an urban view, as with recovery assessed using info on changes in diastolic blood pressure.
Perception of Health
There are some evidence links natural views and better-perceived health. Office workers with a more natural view assess their own health more positively than people with less natural views. Moreover, inmates whose views from their cells are more natural were found to visit a prison infirmary less often than people whose cell windows opened onto a courtyard.
Improvements in mood have been linked to views of nature. After a stressful event, seeing unthreatening nature has been linked to an increase in positive affect and a decrease in negative affect. In general, after watching movies of nature scenes positive mood increased more while negative ones decreased more significantly than when movies of urban scenes were viewed. People recovered faster physiologically from watching a stressful movie when they watched a second movie of a natural environment than when they watched an additional movie of an urban environment. The people watching nature videos indicated that their moods were more positive and they were less scared and angry than those who watched the urban videos.
