This is Scientific American's 60-Second Science. I'm Adam Hinterthuer. Got a minute?

After a bad day at the office, we’re more likely to flip¹ on a nature channel than find a flower-filled meadow or sunny beach to lower our stress. But if you can’t head outdoors, you might want to at least have a look. A report in June’s journal of Enviromental Psychology² says televised nature is no match for a good old window. In the study University of Watshington researchers had students perform a series of challenging mental tests. They hooked each student up to a heart monitor to record higher heart rates caused by the stress of completing the assignments. Some students worked in an office with a view of the university's tree-filled grounds, while others watched a live camera feed of the exact same view on a plasma³ screen TV. Both groups stole glances a  similar number of times. But window gazing students looked longer and were quicker to lower their stressed-out heart rates. In the time of obesity⁴ and nature deficit⁵ disorders⁶ , the researchers say, it's important to remember that your TV may be a window on the world, but it's no substitute for the real deal.

Thanks for the minute. For Scientific American's 60-Second Science. I'm Adam Hinterthuer.
