Every year, as winter fades and spring approaches, we engage in a familiar ritual: adjusting our clocks for daylight saving time (DST). This year, DST began on Sunday, March 9, 2025, and will continue until Sunday, November 2, 2025. The purpose? To make better use of natural daylight, giving us longer evenings while reducing the need for artificial lighting.

However, as we make this adjustment, we also face debates over its effectiveness, concerns about health flow, and discussions about the future of timekeeping in the United States.

The History and Purpose of Daylight Saving Time

Daylight saving time has a long and somewhat controversial history. The concept of adjusting clocks to better align with natural daylight was first proposed by Benjamin Franklin in 1784. While his idea was largely satirical—suggesting that Parisians could save candles by waking up earlier—it wasn’t until World War I that DST was implemented in various countries, including Germany, to conserve fuel and energy. The United States adopted daylight saving time in 1918 as a wartime measure, and after several repeals and reinstatements, it became a more permanent fixture with the Uniform Time Act of 1966.

The primary goal of DST is to extend daylight into the evening hours, which proponents argue helps reduce energy consumption, boosts economic activity, and provides more opportunities for outdoor recreation. However, the true benefits of DST are widely debated, and as society has evolved—with changes in electricity use, work habits, and sleep patterns—many wonder if it still serves its intended purpose.

The Myth of Energy Savings

One of the most commonly cited reasons for DST is energy conservation. The idea is that by shifting an hour of daylight from the morning to the evening, we reduce the need for artificial lighting and heating in homes and businesses. However, modern research challenges this assumption.

A 2008 study by the U.S. Department of Energy found that DST reduces electricity usage by a modest 0.03%. Meanwhile, a study conducted in Indiana found that while DST reduced lighting costs, it led to higher air-conditioning use in the evenings, effectively canceling out any energy savings. A Yale economist also concluded that DST’s impact on energy savings is negligible, given the modern reliance on air conditioning, electronics, and shifting work schedules.

Ultimately, while DST may have had a more noticeable effect in the early 20th century, its relevance in today’s world of energy-efficient lighting and 24/7 lifestyles is questionable.

Potential Changes to Daylight Saving Time

The debate over daylight saving time isn’t just about energy—it’s also about how it affects people’s daily lives. In recent years, there has been growing momentum to either make DST permanent or abolish it altogether.

In 2022, the U.S. Senate passed the Sunshine Protection Act, a bill that aimed to make daylight saving time permanent. While the bill did not pass the House of Representatives, discussions continue at both the state and federal levels. If such a law were to pass, it would eliminate the biannual time change, keeping the country on daylight saving time year-round.

Proponents of permanent DST argue that it would improve public health, reduce traffic accidents, and boost economic activity by extending daylight hours into the evening. However, critics point out that permanent DST could lead to darker mornings in the winter, which might negatively affect students and workers who have to start their day before the sun rises.

Another possibility is to switch permanently to standard time, which some sleep experts and health professionals advocate for. They argue that standard time is more aligned with human circadian rhythms and leads to better sleep quality and overall health. In fact, multiple studies indicate that the disruption caused by DST—particularly the spring transition—can lead to increased risks of heart attacks, strokes, and mood disorders.

Health Flow of the Time Change

While many people enjoy the longer evenings that DST provides, the transition itself can be rough. The loss of an hour of sleep in the spring has been linked to several short-term health risks, including:

• Increased Risk of Heart Attacks: Studies have shown that in the days following the shift to daylight saving time, there is a slight but measurable increase in heart attacks. The disruption of sleep patterns and biological rhythms is believed to be a contributing factor.

• Higher Rates of Traffic Accidents: Losing an hour of sleep can lead to increased drowsiness, making the roads more dangerous. Research has found a spike in car accidents in the days following the time change.

• Mood Disruptions and Mental Health Concerns: Sleep deprivation, even by an hour, can affect mood, cognitive function, and overall well-being. People with existing mental health conditions, such as depression or anxiety, may feel the effects more strongly.

• Workplace Injuries: Studies on workplace accidents have shown that employees tend to experience more injuries in the days following the spring time change, likely due to fatigue and decreased alertness.

Given these concerns, experts suggest taking proactive steps to ease the transition.

Adjusting Your Body to the Time Change

If you find yourself struggling with the shift to daylight saving time, here are some strategies to help your body adjust:

Get More Morning Sunlight – Exposure to natural light in the morning helps reset your internal clock, making it easier to wake up earlier.

Shift Your Sleep Schedule Gradually – Instead of abruptly changing your wake-up time, try adjusting it by 15 minutes each night leading up to DST.

Avoid Stimulants Before Bedtime – Caffeine and alcohol can interfere with sleep, making it harder to adjust to the new schedule.

Take Short Naps if Needed – A 20-minute nap in the afternoon can help counteract some of the effects of sleep deprivation without interfering with nighttime sleep.

Be Patient With Yourself – It may take a few days for your body to fully adjust. Allow yourself extra time in the mornings and be mindful of how the time change might affect your concentration and energy levels.

The Impression on Businesses and Society

Daylight saving time affects various industries differently. Retailers, restaurants, and recreational businesses generally support DST, as longer daylight hours encourage people to shop, dine out, and engage in outdoor activities. The golf industry, for example, has been a strong advocate for DST, as the extra hour of evening light allows for more rounds of golf, increasing revenue.

On the other hand, industries that rely on early morning productivity, such as agriculture, have historically opposed DST. Farmers argue that the time change disrupts their schedules, particularly in the spring when they are already working long hours during planting season.

There are also societal implications of DST, particularly regarding work-life balance. Longer daylight hours can encourage people to spend more time outdoors, which can have mental and physical health benefits. However, the trade-off is that many people find the time shift disruptive to their routines.

Looking Ahead: The Future of DST

As we continue to debate the merits of daylight saving time, it remains to be seen whether the U.S. will eventually adopt a permanent time system. While some states have passed legislation in favor of permanent DST, federal approval is still required to make the change nationwide.

Until then, we will continue to follow the familiar pattern of “springing forward” in March and “falling back” in November. Whether you love it or hate it, DST is a reality we must navigate—at least for now.

As we adjust to the time change, remember to be kind to yourself and take steps to ease the transition. Whether that means getting extra sunlight, being mindful of your sleep habits, or simply embracing the longer evenings, finding what works best for you can make all the difference.
