On Sunday, Americans across most of the country set their clocks back one hour, marking the end of daylight saving time (DST) and the return to standard time. This twice-yearly ritual, established more than a century ago, has been a point of contention in recent years, with many experts calling for an end to clock changes altogether. Despite proposals like the Sunshine Protection Act, aimed at making DST permanent, federal legislation has yet to advance, leaving Americans to continue shifting their schedules twice each year.
Health Implications of DST Shifts
Sleep experts and public health groups have argued that the disruption caused by DST is more than a mere inconvenience. Studies have shown that the “spring forward” in March correlates with an increase in car accidents, heart attacks, and strokes, likely due to the sudden loss of an hour’s sleep. The fall “backward” adjustment, although less disruptive, still requires individuals to adapt to earlier nightfall, impacting sleep patterns and productivity for days or even weeks. As a result, many health professionals advocate for permanent standard time rather than DST, believing that the latter’s extended evening light may compromise sleep quality in the long term.

A Century-Old Tradition Meets Modern Pushback
Daylight saving time was first introduced in the U.S. during World War I to conserve energy. Initially running from April to October, US Congress extended the practice in 2005, moving DST to the second Sunday in March through the first Sunday in November. Yet, this strategy has evolved with mixed results, as energy savings from DST are minimal compared to its potential health costs.
Notably, past attempts to make DST permanent have failed. The last experiment in the 1970s was quickly reversed due to safety concerns, as children faced darker mornings, and public sentiment shifted. Now, with 20 states ready to make DST year-round if Congress approves, proponents argue that this could create stability in daily routines and support businesses that benefit from extended daylight hours. Critics contend that permanent standard time would better align with human circadian rhythms.
Legislative Stalemate on Time Changes
The Sunshine Protection Act, reintroduced by Senator Marco Rubio in 2023, aimed to make DST year-round. However, while the Act passed the Senate in 2022, it failed to reach a vote in the House, stalling in committee. This legislative inaction reflects regional differences: while states like Florida and California support year-round DST, others see more benefits in permanent standard time. Federal law allows states to adopt standard time unilaterally but requires congressional approval for permanent DST, leaving the matter unresolved.
As Americans prepare to set their clocks back this weekend, the debate around daylight saving time remains front and centre. Unless Congress acts, the next “spring forward” will come on March 9, 2025, once again stirring questions on the value of this enduring, if contentious, time-change tradition.
