The latest evidence: In a new study published in the journal Environmental Psychology, researchers found that people who simply looked at a photo of nature for only 40 seconds had improved focus and relieve stress. That’s right, they didn’t even need to go outside! (Though clearly, the effect still applies if you do.) A micro-break viewing a green, but not concrete roof city scene, can sustain attention and restore the good mental condition. Your mission: Set a timer of 40s to take a break. Finish all the green nature pictures below, or even pick the one you like to set as the desktop wallpaper.
