Spring ahead by 1 hour and still feel good all day.
Many find that irritating enough that it has galvanized political movement: Since 2018, 18 states have passed laws to provide for year-round daylight saving time—if such a change were authorized by Congress, according to the National Conference of State Legislatures. And there is pending legislation in more than 26 states to abolish the time change one way or another, leaving the clocks on either permanent standard or daylight saving time.
One hour of lost shut-eye isn’t really the problem: Time changes can wreak havoc on our internal circadian rhythms—the natural cycles that govern a wide range of the body’s processes.
Suddenly waking up in the dark makes this situation even worse. “Light in the morning helps to set our circadian rhythms,” says Nate Watson, MD, professor of neurology at the University of Washington and co-director of the UW Medicine Sleep Center. “Right after the time change, we won’t have that natural wake-up cue.”
Most people can adjust to a 1-hour time difference within a day or two, but don’t be surprised if you struggle longer.
