It’s hard to overstate how much good nature does for our well-being: Study after study documents the psychological and physical benefits of connecting with nature. People who are more connected with nature are happier, feel more vital, and have more meaning in their lives.

Even in small doses, nature is a potent elixir: When their hospital room had flowers and foliage, post-surgery patients needed less painkillers and reported less fatigue. And merely looking at pictures of nature does speed up mental restoration and improves cognitive functioning.
