This is Scientific American's 60-Second Science, I am Karen Hopkin. This will just take a minute.

It’s refreshing1. It’s invigorating. And it leaves you feeling truly alive. No, I’m not talking about a cold shower or a fruit smoothie with a mochachino chaser. I’m talking about nature. Because according to a study published in the Journal of Environmental Psychology2, getting outside—or even just thinking about it—can increase your vitality3.

Hiking, biking or walking in the woods can be revitalizing. But why? Is there something special about the great outdoors that recharges our batteries? Or is it that enjoying nature often involves physical activity and, unless you’re Henry David Thoreau, interacting with others?

To find out, psychologists conducted a series of experiments to isolate4 nature from the equation. In one study, for example, they had undergraduates take a 15-minute walk along a tree-lined river bank or through an indoor hallway. And they quizzed students on how energized5 they felt before and after the stroll.

The results: participants who spent time outside, whether alone or with company, reported greater feelings of vitality. It even worked when the students looked at pictures of plants, or imagined being outdoors. So when you’re looking for that late-afternoon energy boost, try a walk in the park. Think of it as a "leaf" of absence.

Thanks for the minute for Scientific American's 60-Second Science. I am Karen Hopkin.
