From a Washington Post article:
Sleep experts widely agree with the Senate that the country should abandon its twice-yearly seasonal time changes. But they disagree on one key point: which time system should be permanent. Unlike the Senate, many sleep experts believe the country should adopt year-round standard time.(And why am I writing about this and not Ukraine again? Because I don't have to write about Ukraine. The entire US Senate didn't just vote to support Putin, did it?)
“We do applaud stopping the switching during the course of the year and settling on a permanent time,” said Jocelyn Cheng, a member of the AASM’s public safety committee. But, she added, “standard time, for so many scientific and circadian rationales and public health safety reasons, should really be what the permanent time is set to.”
Daylight saving time “does not ‘save’ evening light at all, it simply steals it from the morning when it is necessary to maintain our healthy biological rhythms.” (David Neubauer, an associate professor of psychiatry and behavioral sciences at Johns Hopkins University)
Experts say circadian misalignment has been associated with adverse effects on cognition and mood as well as cardiovascular and metabolic function. “It’s really not a good thing to have your internal body clocks out of sync,” Zee said. “Imagine being in jet lag a lot of the time; it can’t be good for you.” (Phyllis Zee, chief of sleep medicine at Northwestern University’s Feinberg School of Medicine)
The current enthusiasm for permanent daylight saving time is “grossly misguided,” said Neubauer, who predicted a return to “the extremely unpopular 1970s dark winter mornings with commuters going to work and children going to school long before sunrise, inevitably leading to injuries and fatalities.”
Zee said her “heart sank” when she saw the news of the Senate vote. Of the three potential time systems for the country to be on — permanent standard, biannual switching and permanent daylight saving time — she said, the last is “probably the worst choice.”
