Scientists, too, have concluded that spending time in nature is connected to all sorts of health benefits. The gentle burbling of a brook or the sound of the wind in the trees shifts your nervous system into a relaxed state, according to a 2017 Scientific Reports paper, and data reveals that people who have regular access to nature are less likely to be on antidepressants. Expectant mothers who spend time in nature have healthier babies, and being around plants can even strengthen our immune system and prevent illness.
