While it may seem obvious that a good hike through a forest or up a mountain can cleanse your mind, body, and soul, science is now discovering that hiking can actually change your brain… for the better! Aside from the almost instant feeling of calm and contentment that accompanies time outdoors, hiking in nature can reduce rumination. Many of us often find ourselves consumed by negative thoughts, which takes us out of the enjoyment of the moment at best and leads us down a path to depression and anxiety at worst. But a recent study published in Proceedings of the National Academy of Sciences found that spending time in nature decreases these obsessive, negative thoughts by a significant margin.
