Our environment has never changed quite as rapidly as it has during the past couple hundred years. Most of the human population lives in cities, spending more than 90% of their time indoors. We no longer live in the environment we have been adapted to throughout our evolutionary history.

We feel at our best when we are outdoors, hiking in a forest or having a walk in a park, looking at the ocean or sleeping underneath the starry sky. Why not bring that feeling where we most spend our time in?
