Most of America will move clocks back one hour at 2 a.m. as daylight saving time ends and standard time resumes. This annual change started on March 9 this year and originally began in 1918 to conserve fuel during World War I.
The system has been losing popularity over the years. According to a recent AP-NORC poll, 47% of adults oppose daylight saving time while many still favor it. Currently, all states observe daylight saving time except Arizona and Hawaii, which do not change their clocks.
Kenneth Lee, a neurologist and medical director of the University of Chicago Medicine’s Sleep Center, advises easing into the time change:
Lee, a father of two young boys, recommends parents use the same gradual approach—changing clocks early and moving bedtime back bit by bit several nights before the switch.
"Begin pushing back their bedtime a few nights before Sunday for 15 to 20 minutes each night." — Kenneth Lee
