Stop the clock!

A rare moment of agreement unfolded in the U.S. Senate this week, as lawmakers from both parties voiced strong support for ending Daylight Saving Time (DST). During a Senate Commerce Committee hearing, concerns were raised over the biannual clock changes and their negative effects on health, safety, and productivity.

Health Risks Tied to Time Changes

Senator Ted Cruz, R-Texas, opened the hearing by acknowledging that DST was originally introduced to reduce electricity usage. However, he argued that this century-old reasoning no longer holds up in today’s world.

“We change our clocks twice a year, and while many see it as a small nuisance, the health and economic impacts are far greater,” Cruz said.

Dr. Karin Johnson, a Massachusetts-based neurologist, highlighted the medical dangers tied to these time changes. She explained how losing an hour in spring can disrupt sleep patterns, increase cardiovascular problems, and disturb the body’s natural circadian rhythm.

Does Extra Daylight Help the Economy?

While some testified that DST brings revenue for industries like golf and evening tourism, others challenged its overall benefits. Farmers, for example, depend on early morning sunlight and argue that the time change negatively affects their operations.

Senator Lisa Blunt-Rochester, D-Delaware, supported the idea of a permanent time standard, noting that while each state’s needs may vary, there’s widespread public support for consistency.

“What works in Delaware might not work in Washington State,” she said. “But the time has come to figure this out.”

Previous Attempts to Reform DST

The discussion also revisited past efforts to make DST permanent. One notable example was Senator Marco Rubio’s stalled bill that aimed to end clock changes altogether.

Another historical moment was recalled by Scott Yates, founder of the “Lock the Clock” movement. He shared how President Richard Nixon tried a permanent DST during the 1970s energy crisis, only to repeal it months later due to public backlash.

“Imagine coming back from holiday break and losing an hour of sleep. It was deeply unpopular,” Yates said.

Mental Health & Safety Concerns

Senator Blunt-Rochester emphasized how the time shift can increase risks like mood disturbances, hospital admissions, and even heart attacks. Senator Edward Markey, D-Massachusetts, humorously dubbed “The Sun King” for his long-time advocacy on the issue, agreed it’s time for lasting reform.

Cruz closed the discussion with a tongue-in-cheek remark, joking that if there had been more daylight, even the infamous Watergate break-in might have been avoided.

What Happens Next?

While the hearing revealed bipartisan momentum, there’s still no firm decision on whether the U.S. will move toward permanent Standard Time or Daylight Time. However, one thing is clear: lawmakers are ready to stop turning back the clock.

Conclusion

As the debate continues, the demand for a unified, evidence-based solution grows stronger. With health experts, lawmakers, and citizens raising valid concerns, it's clear that the U.S. needs a fresh look at how time is managed across states. Whether it leads to permanent Standard Time or a revised DST policy, one thing is certain — change is ticking closer.

FAQ

Daylight Saving Time (DST) was originally created to reduce electricity use by extending daylight hours in the evening. The idea was that people would use less artificial lighting. However, in today’s energy-efficient world, experts argue that the benefits of DST are outdated.

Both Republican and Democratic lawmakers say DST causes more harm than good. Health risks like sleep disruption, increased heart issues, and more auto accidents are major concerns. They also believe the economic impact is no longer as beneficial as it once was.

Doctors have found that losing an hour of sleep in spring can disturb the body’s natural clock (circadian rhythm), increasing the risk of heart attacks, strokes, and mood disorders. These effects are especially harmful right after the time change.

While some businesses—like golf courses and tourist attractions—benefit from longer daylight hours, other industries, like farming, are negatively impacted. The overall economic gain is now seen as minimal and not worth the health and safety trade-offs.

Yes, during the 1970s energy crisis, President Nixon made DST permanent for a short time. But the move was so unpopular that it was quickly reversed. More recently, Senator Marco Rubio introduced a similar bill, but it didn’t pass in the House.
