Exposure to blue sky improves alertness, a new study indicates. |
New research in Sweden shows being exposed to blue light speeds up reaction time on visual tests. For adults, an hour of blue light worked better than two to three cups of coffee.
Why? When blue light hits your retina, it activates the sections of your brain that make you more alert, especially where cognitive functions are concerned.
Just another reason to hit the trail!
