Clock Change Clash: Why Scientists Warn Against Permanent Daylight Saving

Every fall, Americans flip their clocks back an hour. But this year, politicians want to skip that step for good. They’re pushing to make daylight saving time permanent instead of switching back and forth twice a year.

Scientists aren’t happy about it. A new report says permanent standard time is better for health. Morning light matters most for our body clocks. When sunrise comes later, our sleep and mood suffer.

The report looked at how time affects people’s health. Even though it was done in Canada, experts say it applies to the U.S. too. Most of the studies reviewed were from American researchers.

Politicians love the idea of keeping evenings bright. They say it helps people stay active, shop, and enjoy time outside. President Trump supports the plan. The House passed the Sunshine Protection Act this summer.

But the Senate might block it. Some senators worry there aren’t enough votes. Past attempts failed. States can’t switch alone—they need Congress to say yes first.

Critics point to the 1970s. Back then, the U.S. tried permanent daylight saving time. Kids walked to school in the dark. Trains ran late. People didn’t like it.

Senator Tom Cotton called it a bad idea. He said families in Arkansas don’t want their children going to school in darkness. His comments came after Trump shared Cotton’s phone number online to pressure him.

Supporters like Senator Rick Scott say extra evening light means more family time. People can play with kids, walk dogs, or talk to neighbors.

Nineteen states are ready to switch if Congress allows it. Some will only do it if nearby states agree. The debate continues as lawmakers weigh politics against science.
