The Cost of Changing to Daylight Savings Time and Back Again

Daylight savings time was initially introduced as an energy-saving measure during World War I and later adopted more broadly in the mid-20th century. The idea was simple: extend evening daylight hours to reduce electricity use. But in today’s world, where energy consumption is more complex than just lighting, does this practice still serve a purpose? Many studies suggest that whatever minor energy savings occur are offset by increased heating and cooling costs, making DST an outdated and unnecessary practice.

Lost Productivity and Workplace Disruptions

Switching to and from daylight savings time isn’t just an annoyance; it carries a hefty price tag in lost productivity. Businesses across the country experience a noticeable dip in efficiency as employees struggle to adjust to the time change.

Studies show that in the days following the shift, workers report feeling groggy and less focused. This leads to an increase in mistakes, slower performance, and a general lag in workplace output.

Beyond productivity, there is also a rise in workplace accidents. Fatigue-related errors become more common, particularly in industries that require high levels of concentration, such as healthcare, transportation, and manufacturing.

The economic toll isn’t just theoretical. Research estimates that U.S. businesses lose an astounding $434 million annually due to productivity dips caused by DST-related sleep deprivation.

For an economy that thrives on efficiency and output, the biannual time change disrupts operations far more than it benefits them. Is it worth the cost?

The Hidden Danger of Time Shifts

Disrupting the body's internal clock has serious and immediate health consequences. Research shows that in the week following the switch to daylight savings time, heart attack rates spike by 24%. The sudden loss of an hour of sleep puts added stress on the cardiovascular system, increasing the risk of heart attacks and strokes. At the same time, fatigue and disrupted sleep cycles lead to a noticeable uptick in car accidents, as drowsy drivers struggle to stay alert on the road.

Interestingly, the opposite effect is observed when we “fall back” in November. When people gain an extra hour of sleep, heart attack rates actually decline. This pattern suggests that even a small shift in sleep schedules can have profound health consequences. If a single hour can make such a measurable difference, it raises serious concerns about the broader impacts of daylight savings time on public health.

Humans are creatures of habit, and even a small shift in sleep patterns can lead to mood disturbances, higher stress levels, and lower overall well-being. Schools report that students struggle with concentration for days after the time change, and many parents note behavioral issues in younger children. If the goal of society is to foster a well-rested, productive population, daylight savings time is counterproductive.

Does Daylight Savings Time Actually Save Energy?

One of the original justifications for daylight savings time was energy conservation. The idea was that by extending daylight hours into the evening, people would use less artificial lighting, ultimately reducing electricity consumption. In an era when lighting accounted for a significant portion of energy use, this logic made some sense.

However, modern energy consumption is far more complex. Heating and cooling systems now dominate household and business energy use, particularly in regions with extreme weather. When daylight savings shifts the clock, people end up using more air conditioning in the evening during warmer months and more heating in the morning during colder months. Studies have shown that in some areas, DST actually increases energy consumption rather than reducing it, making the original justification obsolete.

The Case for Permanent Standard Time

So, what would happen if we abolished daylight savings time entirely? Some regions have already taken that step, opting for permanent standard time. Arizona and Hawaii, for example, do not observe DST and avoid the biannual disruptions that affect the rest of the country. Residents in these states enjoy consistent sleep patterns, fewer health risks, and more stable schedules without the hassle of changing clocks.

The debate over eliminating DST is not limited to the United States. The European Union has been discussing abolishing the practice altogether, recognizing that the supposed benefits no longer justify the economic and health consequences. With growing evidence that DST causes more harm than good, many policymakers are questioning whether it’s time to leave this outdated tradition behind.

What’s Preventing Change?

If DST is so costly, why do we still have it? Part of the answer lies in political inertia—governments are slow to change policies that have been ingrained for decades. Additionally, some industries, such as retail and entertainment, argue that longer evening daylight hours encourage consumer spending. However, these benefits are marginal at best and pale in comparison to the widespread health and economic costs.

The costs of switching to and from daylight savings time are undeniable. From lost productivity and increased health risks to questionable energy savings, DST no longer serves a meaningful purpose in the modern world. As more countries and regions debate whether to abandon this practice, the evidence overwhelmingly suggests that it’s time to end the twice-yearly clock change for good. The question remains: how much longer will we let tradition dictate policy at the expense of public well-being?

Capital in the Twenty-First Century
by Thomas Piketty. (Translated by Arthur Goldhammer)

In Capital in the Twenty-First Century, Thomas Piketty analyzes a unique collection of data from twenty countries, ranging as far back as the eighteenth century, to uncover key economic and social patterns. But economic trends are not acts of God. Political action has curbed dangerous inequalities in the past, says Thomas Piketty, and may do so again. A work of extraordinary ambition, originality, and rigor, Capital in the Twenty-First Century reorients our understanding of economic history and confronts us with sobering lessons for today. His findings will transform debate and set the agenda for the next generation of thought about wealth and inequality.

Nature's Fortune: How Business and Society Thrive by Investing in Nature
by Mark R. Tercek and Jonathan S. Adams.

What is nature worth? The answer to this question—which traditionally has been framed in environmental terms—is revolutionizing the way we do business. In Nature’s Fortune, Mark Tercek, CEO of The Nature Conservancy and former investment banker, and science writer Jonathan Adams argue that nature is not only the foundation of human well-being, but also the smartest commercial investment any business or government can make. The forests, floodplains, and oyster reefs often seen simply as raw materials or as obstacles to be cleared in the name of progress are, in fact as important to our future prosperity as technology or law or business innovation. Nature’s Fortune offers an essential guide to the world’s economic—and environmental—well-being.

Beyond Outrage: What has gone wrong with our economy and our democracy, and how to fix it -- by Robert B. Reich

In this timely book, Robert B. Reich argues that nothing good happens in Washington unless citizens are energized and organized to make sure Washington acts in the public good. The first step is to see the big picture. Beyond Outrage connects the dots, showing why the increasing share of income and wealth going to the top has hobbled jobs and growth for everyone else, undermining our democracy; caused Americans to become increasingly cynical about public life; and turned many Americans against one another. He also explains why the proposals of the “regressive right” are dead wrong and provides a clear roadmap of what must be done instead. Here’s a plan for action for everyone who cares about the future of America.

Article Recap

Daylight savings time was introduced as an energy-saving measure but has outlived its usefulness. The economic costs include lost productivity and workplace disruptions, while health consequences range from increased heart attack risks to higher accident rates. DST doesn’t significantly save energy and disrupts sleep patterns, leading to psychological strain. Calls for abolishing DST are growing, but political and business interests keep it alive. Is it time to stop the clock on this outdated practice?
