A new study warns that adopting permanent daylight saving time in the United States could carry significant public health and safety consequences, particularly for schoolchildren. Researchers estimate the policy would force American children to make at least two billion additional school commutes in darkness, exposing them to heightened risks and disrupting their biological clocks. The analysis found that fatal crashes involving school-aged pedestrians were roughly twice as likely during dark mornings as after sunrise, underscoring concerns that later sunrises under a fixed daylight saving schedule could place young commuters in harm's way throughout the winter months.
The findings add a cautionary note to longstanding legislative efforts to end the twice-yearly clock change, which proponents argue improves evening light and economic activity. Scientists behind the study suggest that permanent standard time, rather than permanent daylight saving time, would better align school commutes with daylight and support children's circadian rhythms. The research arrives as policymakers at both state and federal levels continue to debate the merits of locking the nation's clocks, with the new evidence urging lawmakers to weigh the safety of student pedestrians and the developmental needs of young people against the convenience of extended evening daylight.
