The U.S. House of Representatives has approved the Sunshine Protection Act, a bill that would eliminate the biannual clock change by making daylight saving time permanent. While President Donald Trump is urging the Senate to pass the measure, the bill faces opposition from health experts and some lawmakers.
The Uniform Time Act and the 2005 Energy Policy shift
The current American system of shifting clocks is rooted in the Uniform Time Act of the 1960s, which established the framework for seasonal time changes. This was further refined by the Energy Policy Act of 2005, which set the specific dates for the transition—the second Sunday in March and the first Sunday in November—according to the report.
Under these existing laws, states are permitted to opt out of daylight saving time entirely, which is why Hawaii and Arizona maintain the same time year-round. the proposed Sunshine Protection Act would maintain this opt-out provision, allowing states to choose standard time over permanent daylight saving time if they find the latter unsuitable for their geography or economy.
Dr. Dayna Johnson's warning on circadian misalignment
The debate over permanent daylight saving time has created a sharp divide between political rhetoric and medical research. President Donald Trump has argued on TruthSocial that ending the clock change would reduce violent crime, car crashes, and cardiac risks. However, as the reprot notes , Dr. Dayna Johnson, an associate professor of epidemiology at the Rollins School of Public Health, suggests the opposite may be true.
Dr. Dayna Johnson argues that permanent daylight saving time is less aligned with human circadian biology, potentially leading to "circadian misalignment." This biological disconnect, she warns, could actually increase the risk of cardiovascular disease and exacerbate sleep debt, which in turn could increase the frequency of traffic accidents.. Dr. Johnson advocates for permanent standard time as the healthier alternative for the human body.
The 8:15 a.m. winter sunrise in Illinois
For residents of Illinois, the Sunshine Protection Act presents a specific geographic challenge. Because Illinois sits on the far eastern edge of the Central time zone, permanent daylight saving time would push sunrise significantly later during the winter months. According to the report, the winter solstice would see the sun rise at approximately 8:15 a.m.
This shift would mean that for nearly two months,sunrise in Illinois would occur after 8 a.m. While this ensures sunsets remain after 5 p.m., critics argue that the prolonged morning darkness poses a safety risk for school children heading to class in the dark. This specific environmental impact has made the legislation particularly contentious for the Chicago-area population.
The split vote among Illinois Congressional representatives
The political landscape in Illinois reflects the divide over the bill. In the House, Republican representatives Mike Bost, Darin LaHood, and Mary Miller all voted in favor of the Sunshine Protection Act. They were joined by several Democrats, including Nikki Budzinski, Sean Casten, Danny Davis, Bill Foster, Robin Kelly, Jan Schakowsky, Brad Schneider, and Lauren Underwood.
However, a significant bloc of Illinois Democrats opposed the measure. Reps. jesús ‘Chuy’ García, Jonathan Jackson, Raja Krishnamoorthi, Mike Quigley, Delia Ramirez, and Eric Sorensen all voted no. This fragmentation suggests that the impact on local constituents—particularly regarding winter safety—is weighing heavily on the state's delegation.
Whether Senators Durbin and Duckworth will support the bill
Despite the House's bipartisan progress, the Sunshine Protection Act remains stalled in the Senate. Senate Majority Leader John Thune and Senator Tom Cotton have expressed opposition to making daylight saving time permanent, and the chamber has yet to officially take up the measure.
A critical unknown remains the stance of Illinois Senators Dick Durbin and Tammy Duckworth. The report indicates it is currently unclear if either senator would vote in favor of the legislation, leaving the final fate of the bill in a state of uncertainty as it awaits a Senate vote.
