The complications of permanent daylight saving time
Consequences for health, religious practices and airline schedules
Spring forward, fall back — that old rule of thumb for resetting clocks at the start and end of daylight saving time may soon be a relic of the past, as the House of Representatives last week overwhelmingly supported a bill to make the time change permanent. And President Donald Trump has expressed his support. After all, people like later sunlight hours. But keeping the clock on summer hours could have negative ramifications.
‘Hidden consequences’
Americans are “tired of the biannual time change,” and making daylight saving time permanent is a “commonsense reform that will improve everyday life for millions,” bill sponsor Rep. Vern Buchanan (R-Fla.) said in a statement, per The Hill. Trump agrees. Passing the bill would be a “very nice WIN for the Republican Party,” he said on Truth Social. But there would be “hidden consequences” to year-round daylight saving, said Axios. Under the reset the “sun won't rise until 8 or 9 a.m. in the winter,” leaving “millions of children” and commuters to start their days “in the dark.”
There would probably be health consequences too. Morning sunlight is “key to maintaining our circadian rhythms” and “overall health,” said The Washington Post. “Circadian misalignment” can cause lost sleep, which in turn is connected to “obesity, Type 2 diabetes, cardiovascular disease, mood disorders” and other health challenges. Americans “would be misaligned all year long,” Vanderbilt University’s Beth Malow said to the paper.

The change would disrupt the daily prayer practices of Orthodox Jews, said NPR. Some prayers “can only be said communally” and are often performed “every morning before heading out for work or school.” The change would be a problem for a “synagogue that has had a morning prayer service for 100 years” if it cannot muster enough of the congregation to “show up at the prayer time close to 9 o'clock because they have jobs,” Rabbi A.D. Motzen, national director of government affairs for Agudath Israel of America, said to the outlet. “Some Muslim prayers and religious observances” would also be affected, said Axios.
Airlines “could take up to two years” to adjust their “complex scheduling” to permanent daylight saving, said CBS News. The shift could affect “crew and aircraft positioning” as well as “domestic and international connectivity,” trade group Airlines for America said in a statement. Trucking and railroad companies that are “also timetable dependent” would face challenges as well, said CBS.
‘Abandoned prematurely’
Congress authorized permanent daylight saving in 1973 to save energy during the oil crisis, said The Independent. The project was “abandoned prematurely” amid concerns about “children and criticisms from the construction and agricultural industries.”
Permanent standard time might be a healthier alternative, said Yahoo News. Stanford University researchers determined that sticking to the regular clock all year would result in “300,000 fewer strokes and 2.6 million fewer people with obesity.” People need “more morning light and less evening light” to have a balanced day, Stanford University’s Jamie Zeitzer said to the outlet.
