If you' re feeling stressed, rather than wallow （沉迷） in watching television, try looking out of the window, with a US study finding scenes of nature can ease off minor stress levels．
Researchers at the Human Interaction with Nature and Technological Systems Lab at the University of Washington set out to look at whether nature, either the real thing or the one depicted （描述） technologically, can impact on minor stress levels．The study involved measuring people' s heart recovery rates from minor stress when they were exposed to a natural scene through a window and when exposed to the same scene shown on a high-definition plasma （等离子） screen, or a blank wall．
The heart rates of people who looked at the scene through the window dropped more quickly than the others．In fact, the high-definition plasma screen had no more effect than the blank wall, the researchers said in a statement．They also found that when people spent more time looking at the natural scene their heart rates tended to decrease more．That was not the case with the plasma screen．
The study, involving 90 college students, is published in the Journal of Environmental Psychology．Technology is good and it can help our lives, but let' s not be fooled into thinking we can live without nature, Peter Kahn, who led the research team, said in a statement．He said people were losing direct experiences with nature and instead experiencing nature represented technologically through television and other media with children growing up watching Discovery Channel and Animal
Planet．But as a species we need interaction with actual nature for our physical and psychological well-being, he said．
