The U.S. House voted 308–117 to approve the Sunshine Protection Act, which would make daylight saving time permanent and end the twice-yearly clock changes. The bill now moves to the Senate, where lawmakers remain divided over the potential for dark winter mornings and disrupted circadian rhythms.
The twice-yearly ritual of shifting clocks forward and backward could soon become history. House of Representatives overwhelmingly voted 308–117 to pass the Sunshine Protection Act, a legislative initiative spearheaded by Florida Republican Representative Vern Buchanan. The bill aims to establish permanent daylight saving time nationwide, eliminating the traditional practice of springing forward and falling back.
Yet, while the House vote represents a major milestone for proponents of year-round daylight hours, the legislation faces a familiar and formidable hurdle: the U.S. Senate. Similar efforts have stalled in the past amid sharp divisions over public safety, children walking to school in the dark, and what sleep experts describe as a fundamental mismatch with human biology.
The House Vote and the Push for Permanent Daylight Saving Time
Supporters of the Sunshine Protection Act argue that locking the clocks forward provides tangible economic and lifestyle benefits. Proponents point out that extended daylight during winter evenings can boost commerce, restaurant patronage, tourism, and outdoor recreation. States like Florida stand to gain an extra hour of winter sunlight for sports facilities, beaches, and businesses operating after standard working hours.
Across the country, nearly 20 states have already passed legislation in recent years to support ending the time changes, contingent upon federal approval.
Medical Experts Warn Against Shifting Away From Standard Time
While lawmakers debate the economic upsides of evening sunlight, major medical and sleep organizations are pushing back. Rather than permanent daylight saving time, groups like the American Academy of Sleep Medicine advocate for permanent standard time, arguing that human bodies are biologically calibrated to standard hours.
Dr. James Rowley, professor of medicine at Rush University and immediate past president of the American Academy of Sleep Medicine, via NBC Chicago, stated that permanent standard time would basically mean that they were on what is, he supposes, biologically the correct time all year round, and added that it is biologically correct because human bodies are more used to and have evolved to be on what would be considered standard time over the years.
Medical professionals emphasize that morning sunlight is critical for synchronizing human circadian rhythms. Dr. Erik Nelson, a psychiatrist with UC Health, notes that losing morning light disproportionately affects individuals vulnerable to seasonal affective disorder. Dr. Nelson explained that even though there would be a little bit more light in the afternoon, evidence shows that morning light is more important for them in terms of synchronizing their biological clock, Dr. Nelson explained.
Furthermore, sleep experts warn that permanent daylight saving time would plunge vast portions of the United States into darkness during early morning hours.
Echoes of the 1974 Energy Crisis and Legislative Roadblocks
The debate over permanent daylight saving time is not entirely new. The United States previously attempted year-round daylight saving time during the energy crisis of the 1970s. Congress instituted a trial period via legislation in 1973, which ran from January 1974 to April 1975. However, public outcry prompted lawmakers to repeal the measure prematurely in October 1974.
During that trial, families voiced intense concern over children commuting to school in pitch-black conditions. Kevin Birth, a professor of anthropology at Queens College who experienced the 1970s trial as a student in Syracuse, New York, recalled leaving for school when conditions felt as though it were midnight and remaining in darkness well into the school day. Similar concerns resonate today among lawmakers in the Senate, where the current bill faces strong opposition.
Senators such as Arkansas Republican Tom Cotton have spoken out against the proposal, warning that enacting permanent daylight saving time would make winter a dark and dismal time for millions of Americans.
What Happens Next in Congress
As the Sunshine Protection Act sits before the Senate, its legislative future remains uncertain. The measure could require up to 60 votes to overcome procedural hurdles and potential filibusters, and deep divisions persist among lawmakers regarding whether morning or evening light should take priority.
Until the Senate completes its review and breaks the stalemate, the established seasonal schedule remains fully in effect. Americans will continue to adjust their clocks twice a year, awaiting a definitive congressional resolution on whether the nation will abandon or preserve the century-old practice of shifting time.
