The clock ticks on a controversial time change

President Donald Trump renewed his push Friday for the Sunshine Protection Act, urging Senate Republicans to pass legislation making daylight saving time permanent. The measure cleared the House in July on a 308-117 vote but faces stiff opposition in the Senate, where Sen. Tom Cotton of Arkansas has become the principal obstacle. The debate highlights a deeper conflict between political convenience and mounting medical evidence warning of long-term health consequences from disrupting natural sleep cycles.

A failed experiment revisited

The 1974 experience looms large over current deliberations. Congress enacted permanent daylight saving time as a two-year experiment beginning January 1974, only to repeal it by October of that same year. Polling at the time showed public support plummeted 30 percentage points in three months after Americans experienced winter mornings with sunrise after 8:30 a.m. in many regions. Cotton, chairman of the Senate Intelligence Committee, cited this historical failure in opposing the measure. In winter, residents in Seattle would see sunrise at 9 a.m., while those in Williston, North Dakota, would wait until nearly 9:45 a.m. for daylight. Cotton argued children would walk to school "in the pitch black." The senator is not alone in his concerns. Sen. Mike Rounds of South Dakota noted some areas of his state would remain dark past 9:30 a.m. under permanent daylight saving time.

Health warnings emerge

While proponents emphasize economic benefits and recreational opportunities from extended evening daylight, medical professionals have raised alarms about chronic health consequences. Neurologists have testified that permanent daylight saving time leads to chronic circadian misalignment. Research associates this disruption with elevated long-term risks for cancer, obesity, heart attacks and depression. Teenagers are considered particularly vulnerable, as their biological clocks naturally run later. Forcing adolescents to start school in winter darkness could severely compromise sleep patterns and academic performance. The American Academy of Sleep Medicine has recommended abolishing seasonal time changes but favors permanent standard time, which aligns more closely with natural light cycles and human biology.

Presidential pressure tactics

Trump intensified the battle Saturday by publishing what appeared to be Cotton's personal cellphone number on social media, urging Arkansas residents to call their senator. "For some reason, Tom is stopping the Bill and, in the Senate, it's very easy to do, it only takes one!" Trump wrote. This is not unprecedented. During the 2016 presidential campaign, Trump released the late Sen. Lindsey Graham's personal phone number after Graham criticized Trump's comments about Sen. John McCain's military service. Cotton responded on social media: "No one likes changing the clock, me included, but Congress has enacted permanent Daylight Savings Time multiple times before and repealed it each time once Americans experienced absurdly late sunrises in the winter. Arkansans don't want their kids going to school in the pitch dark, and I'll always put Arkansas first."

Bipartisan support and growing skepticism

The Sunshine Protection Act drew bipartisan support in the House, with 308 votes in favor. Only 12% of Americans favor the current system of twice-yearly clock changes, according to a 2025 AP-NORC poll. However, 47% oppose permanent daylight saving time, while 40% remain neutral. Rep. Frank Pallone of New Jersey explained his support by noting the current practice is "inconvenient and, frankly, disruptive." Trump argued the measure would benefit commerce, sports and recreation while reducing crime and stress.

The clock stops on political will

The fate of the Sunshine Protection Act now rests in the Senate, where procedural rules allow a single senator to block legislation. Cotton's opposition, combined with historical precedent and emerging health data, creates a complex political calculus. Proponents emphasize the economic costs of clock changes, estimated at millions of dollars annually. Opponents point to the failed 1974 experiment and the documented health consequences of circadian disruption. As the debate continues, Americans face a choice between the appeal of longer summer evenings and the proven risks of winter darkness. History suggests the initial popularity of permanent daylight saving time can quickly sour when reality sets in. Sources for this article include: TheEpochTimes.com CBSNews.com TheGuardian.com
