Waking Times
For Americans, it’s that time of the year again—time to move your clocks an hour ahead; losing a precious hour of sleep in the process. For many, the time change associated with daylight savings time1 (DST) also means spending several days or even weeks feeling generally off-kilter.
As reported by Prevent Disease:2
“A study, published in 2007… combined surveys from 55,000 people in central Europe with data on 50 individuals’ sleeping and wakefulness patterns for eight weeks around the shifts to and from daylight saving time.
The researchers found people never fully adjust their circadian rhythms to the hour shift associated with daylight saving time (or, as it is known in Europe, summer time).
