Fifteen years ago, University of Oxford Professor Kathy Willis read a study that revealed hospital patients recovering from surgery improved three times faster when they looked out of their windows at trees rather than seeing walls. Since then, she has dedicated her research to proving this link between the amount of green space in our lives and our better health, mood and longevity. For the first time ever, Good Nature brings together these recent scientific findings and shares the simple changes we can all make in our lives.
