The early bird gets the worm and may be less depressed, too, according to a recent University of Colorado study. That’s the finding from one of the largest studies exploring the link between sleep-wake preference and mood disorders.
After examining the sleep-wake preferences and depression rates for 32,000 female nurses, researchers found early birds were 12-27% less likely to develop depression.
Although sleep-wake preferences are partly determined by genetics, night owls can train themselves to be earlier risers by dimming the lights at night and trying to get lots of natural light during the day.
