As most of us prepare to ‘fall back’ and gain an extra hour of sleep this November 2nd, experts are sounding the alarm: these twice-yearly clock changes are doing more harm to our health than we realize. While that bonus hour might feel like a gift, it’s actually disrupting our body’s internal clock in ways that can affect everything from our sleep to our mood.
The Science Behind the Shift
New research from Stanford University suggests that the constant back-and-forth between daylight saving time (DST) and standard time is the worst option for our health. The study argues that adopting either permanent DST or permanent standard time would be beneficial, but permanent standard time aligns most naturally with our body’s biology.
Jamie Zeitzer, co-director of Stanford’s Center for Sleep and Circadian Sciences, explains it like this: think of our internal clock as an orchestra conductor. Morning light is key to keeping everything in sync. When this rhythm is disrupted, Zeitzer notes, every system in our body, from metabolism to immune function, operates a little less effectively.
Why Standard Time Might Be the Answer
Major health organizations, like the American Medical Association and the American Academy of Sleep Medicine, already back making standard time permanent. They agree that it better matches our natural light patterns. The shift in spring, when we lose an hour, is particularly tough, with studies linking it to increases in car crashes, heart attacks, and sleep deprivation.
However, even the November shift can be challenging for those already struggling with sleep issues or working non-traditional hours. It’s a significant concern when you consider that about one in three U.S. adults already get less than the recommended seven hours of sleep per night.
Easing the Transition
As the debate continues in Congress, particularly around the stalled Sunshine Protection Act (which aims to make DST permanent), experts offer practical advice for managing the current changes. They suggest gradually shifting your bedtime by 10-15 minutes in the days leading up to the time switch.
Getting sunlight early in the day is also crucial for resetting your body’s natural clock. If you can’t get outdoors, simply sitting by a window can help. Morning sun remains the most effective tool for keeping our internal rhythms on schedule.
