At 2 a.m. on Sunday, most people in the United States will "spring" their clocks forward by one hour for Daylight Saving Time, potentially losing an hour's sleep in the process. To make the transition a little less painful, University of Arizona associate professor of psychiatry Michael Grandner recommends people who observe DST make it a priority to get good sleep – seven or more hours at a stretch – for at least a few nights before the clock change. That way, "you're coming from a place of strength," not sleep deprivation.
