If there is one finding in psychology research you can be pretty sure of, it’s that spending time in nature reduces stress. Study after study shows that when humans get outside, both their perceived feelings of tension and biological markers of stress go down. Here’s one from Cornell and another from Harvard if you need further convincing.

This is handy for entrepreneurs to know. If your business or your life is feeling overwhelming you might want to plan a hike or a park picnic next weekend.

The problem is, the utility of this insight has been limited to times when you can physically leave your office. That is until a recent study appeared in The Journal of Environmental Psychology. The research by a Finnish and Norwegian team found you can use nature to significantly reduce your stress no matter where you are. All you need is your brain and five quiet minutes.
