Being surrounded by nature is not only relaxing—it also helps us think better. That’s because the view of a tree-lined path doesn’t require our full concentration. We can take it in at the same time that our mind wanders to other things, which is restorative. Researchers have found that photos of nature provide the same benefit. No wonder that photo of our last outdoor vacation is so calming to look at.

Have you ever been outside at night, taken a deep breath and looked up at the sky? You may find those moments as calming as gazing out at the ocean or a range of mountains. Some people consider the dark sky to be as much of a natural resource as the ocean. Inhale and enjoy.

Being in nature improves our mental health. A study in Environmental Science & Technology has found that we benefit after just five minutes of physical activity in nature. To improve your mood, exercise in a backyard or park…or walk on a nature trail.
