Going outside is as good as caffeine: study

Taking a walk outside can be as revitalizing as a caffeinated drink, according to a new study from U.S. researchers who found that people don’t even have to do something active outside to get these benefits. The bond between human bodies and nature makes “people feel more alive,” said psychology professor Richard Ryan in the Journal of Environmental Psychology, the Telegraph reports. In a study of five different experiments, they exposed 537 volunteers to active and sedentary situations inside a building and outside or by a river. The results showed that students found themselves experiencing a massive increase of vitality after 20 minutes outside, although an improvement was seen even when they imagined themselves outside.
