The Bi-Annual Time Shift: A Painful Habit That May Not Be Necessary Anymore
As the clocks spring forward once again, it's worth taking a step back to consider why we even bother with daylight saving time (DST). This bi-annual ritual of adjusting our schedules by an hour has been in place for over a century, but its effectiveness is being called into question.
According to Dr Natalie Dautovich, senior research fellow at the National Sleep Foundation and associate professor at Virginia Commonwealth University, what matters most to our long-term health is aligning our societal clocks with human biology. In other words, standard time best matches our natural circadian rhythms and the sun's timing. With DST, our bodies get confused by the mismatch between the environment and our internal clock.
Research has shown that this disruption can have serious health effects, including sleep disturbances and a rise in health issues like heart attacks and strokes. The day after clocks "spring forward" is especially dangerous: both sleep loss and circadian misalignment can lead to nonrestorative sleep, motor vehicle accidents, increased cardiovascular events, and an upsurge in hospital admissions.
In the US, 54% of Americans say they're ready to scrap DST altogether, while 48% prefer permanent standard time. In the UK, a whopping 57% want to bid farewell to DST. The public is divided on what should take its place, but one thing is clear: our current system is no longer serving us.
But does DST even save energy? The answer is no. Modern energy use has evolved such that daylight savings time no longer provides a measurable energy benefit. In fact, the original argument for DST – that it helps farmers – was completely untrue. Farmers actually resisted it because the shift can disrupt livestock and harvest schedules.
Despite this, some argue in favor of DST on the grounds that it stimulates the economy by giving people an extra hour to engage in outdoor activities after work. However, research suggests that the costs of DST may be greater than the benefits. One study estimated that the toll DST takes on people's health costs economies over €750 ($875) per capita each year.
So what's next? Some experts believe it's time for us to rethink our approach to DST and consider adopting permanent standard time or permanent summer time instead. Others propose a more nuanced solution, where countries can opt out of the bi-annual time shift altogether.
As we prepare to "fall back" into standard time, there are a few things you can do to make the transition less painful: get exposure to sunlight first thing in the morning, avoid caffeine and heavy meals close to bedtime, maintain a consistent sleep schedule, and prioritize your overall sleep habits.
But ultimately, truly addressing the disruptive nature of DST requires more than just individual hacks – it requires a fundamental rethink of our societal norms and priorities. It's time for us to consider what's really best for our health, economy, and environment before we blindly keep perpetuating this bi-annual ritual that may not even be necessary anymore.
