Feeling low? Snap up the shades! A recent study of 49 staffers at a Midwest university found that those with office windows were livelier and more physically active, and got an average of 6 minutes more sleep than colleagues in windowless work spaces. Another small study conducted by researchers at a Texas hospital similarly found that nurses exposed to more natural light on the job had lower blood pressure and better moods than those working under more artificial light. Natural light, notes one of the researchers, is restorative and stress-reducing, and helps the brain regulate the release of hormones such as sleep-inducing melatonin.
