Daylight Saving Time Ends Sunday Amid Controversial Stanford Study

UPDATE: Daylight saving time officially ends on November 5, 2023, and millions of Americans will “fall back” one hour this weekend. A new Stanford University study reveals urgent concerns about the health impacts of this biannual clock change, suggesting it may be time to abolish the practice altogether.

As many as 300 million people across the U.S. will adjust their clocks this Sunday, gaining an extra hour of sleep. However, the implications of this shift extend far beyond a simple time change. The Stanford research highlights a troubling connection between daylight saving time and negative health outcomes, including increased rates of obesity and strokes.

Eugene You, a 20-year-old philosophy student at UC Berkeley, expressed surprise at the upcoming time change, stating, “I had no idea you’d have to actually adjust the clocks.” Meanwhile, fellow student Thomas Tang acknowledged the change’s minimal impact, saying, “I’ll take one more hour of sleep.”

Not all residents share the same indifference. Local parent Catherine reported that her young sons find the transition challenging, saying, “It’s confusing for the kids when we pick them up from daycare, especially because my eldest is afraid of the dark.” She anticipates a period of adjustment for her family following the time shift.

The Stanford study, published in September, analyzed health data from the Centers for Disease Control and Prevention and highlighted that eliminating daylight saving time could reduce obesity rates for over 2.6 million Americans and potentially prevent 200,000 to 300,000 strokes. Researchers found that the switch disrupts the body’s circadian rhythm, leading to adverse health effects.

Daylight saving time is not embraced globally; most Asian countries, like You’s home, do not observe it. In the U.S., only Arizona and Hawaii maintain standard time year-round. The practice has seen decreasing support, with only 40% of Americans favoring it in a recent Gallup poll, a significant decline from the 75% approval in the late 1990s.

Despite these findings, the study acknowledges mixed outcomes regarding public health. “Our data use an idealized light exposure pattern and do not model expected human behavior,” researchers noted. This complexity suggests that a one-size-fits-all approach may not be feasible.

Students like Onyinye Boardman, a 20-year-old media studies major at UC Berkeley, support the idea of a permanent time change. “Why don’t we just stick to one?” she questioned, reflecting a sentiment shared by many who find the biannual shift unnecessary.

As the clock strikes 2 a.m. this Sunday, many will face adjustments in their daily routines. The emotional and physical impact of this time shift is evident, prompting a broader discussion about the future of daylight saving time in the U.S. Will lawmakers take action to eliminate this ritual for good?
