Now, you knew when the Senate all got together to pass a bill changing Daylight Savings Time, they had to be getting it wrong, right? Via the Washington Post:
After the Senate voted unanimously and with little discussion Tuesday to make daylight saving time permanent, the American Academy of Sleep Medicine issued a statement cautioning that the move overlooks potential health risks associated with that time system. (The legislation, which would take effect next year, must get through the House and be signed by President Biden to become law.)
“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.”
The AASM made this stance clear in 2020 when it released a position statement recommending that the country institute year-round standard time. Its reasoning, in part, is that standard time is more closely associated with humans’ intrinsic circadian rhythm, and that disrupting that rhythm, as happens with daylight saving time, has been associated with increased risks of obesity, metabolic syndrome, cardiovascular disease and depression.
They're senators! They got confused!
Not to mention, we did do this in the '70s, and it wasn't popular:
Congress had voted on December 14, 1973, to put the US on daylight saving time for two years. President Nixon signed the bill the next day. The US had gone to permanent daylight saving time before, during World War II. Then, too, the measure was enacted to save fuel. Permanent DST wasn’t close to the wackiest idea about time floating around—Paul Mullinax, a geographer who worked at the Pentagon, came up with the idea of putting the continental US on a single time zone. “USA Time” would apply from Bangor to Barstow, eliminate jet lag, and standardize TV schedules. His idea even got traction in Congress, via a bill from US Representative Patsy Mink of Hawaii. “The human being is a very adaptive animal,” he said. “There is no reason we have to be a slave to the sun.”
[...] By August, though, as the Watergate scandal caused the Nixon administration to crumble, the country was ready to move on from its clock experiments. While 79 percent of Americans approved of the change in December 1973, approval had dropped to 42 percent three months later, the New York Times reported. Seven days after President Nixon resigned, US Senator Bob Dole of Kansas introduced an amendment in August that would end the DST experiment. It passed. A similar bill passed the House. In late September, the full Congress passed a bill that would restore standard time on October 27. President Ford signed it on October 5. Energy savings, a House panel noted, “must be balanced against a majority of the public’s distaste for the observance of Daylight Saving Time.”
