According to a new study published in Scientific Reports, spending two hours a week in the natural environment can improve your physical and mental health. You don't have to spend two hours in one hit, you can spend four half hour blocks in nature. You don't have to climb a mountain either, you can just go for a leisurely walk. Just get out of the burbs and to the park, the beach, the river, the bush (maybe take a friend). Just because it's the middle of winter is no excuse, just rug up and get out there. I took this photo on a drizzly day this week when I was walking my dog.
