The case against daylight saving, from a neurologist and sleep expert

The case against daylight saving, from a neurologist and sleep expert

“Springing forward” is connected with negative health effects, an expert explains.

As people in the U.S. prepare to set their clocks ahead one hour on Sunday, March 10, 2024, I find myself bracing for the annual ritual of media stories about the disruptions to daily routines caused by switching from standard time to daylight saving time.

About one-third of Americans say they don’t look forward to these twice-yearly time changes. And nearly two-thirds would like to eliminate them completely, compared with 17% who aren’t sure and 21% who would like to keep moving their clocks back and forth.

But the effects go beyond simple inconvenience. Researchers are discovering that “springing ahead” each March is connected with serious negative health effects, including an uptick in heart attacks and teen sleep deprivation. In contrast, the fall transition back to standard time is not associated with these health effects, as my co-authors and I explained in a 2020 commentary.

I’ve studied the pros and cons of these twice-annual rituals for more than five years as a professor of neurology and pediatrics and the director of Vanderbilt University Medical Center’s sleep division. It’s become clear to me and many of my colleagues that the transition to daylight saving time each spring affects health immediately after the clock change and also for the nearly eight months that Americans remain on daylight saving time.

Why our bodies are thrown off by DST

Americans are split on whether they prefer permanent daylight saving time or permanent standard time. But a growing number of states are supporting permanent standard time.

However, the two time shifts — jolting as they may be — are not equal. Standard time most closely approximates natural light, with the sun directly overhead at or near noon. In contrast, during daylight saving time from March until November, the clock change causes natural light to be present one hour later in the morning and one hour later in the evening according to clock time.

Morning light is essential for helping to set the body’s natural rhythms: It wakes us up and improves alertness. Morning light also boosts mood — light boxes simulating natural light are prescribed for morning use to treat seasonal affective disorder.

Although the exact reasons why light activates us and benefits our mood are not yet known, this may be due to light’s effects on increasing levels of cortisol, a hormone that modulates the stress response, or the effect of light on the amygdala, a part of the brain involved in emotions.

Adolescents also may be chronically sleep-deprived due to school, sports and social activities. For instance, many children start school around 8 a.m. or earlier, which means that during daylight saving time they get up and travel to school in pitch darkness.

The body of evidence makes a good case for adopting permanent standard time nationwide, as I testified at a March 2022 Congressional hearing and argued in a recent position statement for the Sleep Research Society. The American Medical Association recently called for permanent standard time. And in late 2022, Mexico adopted permanent standard time, citing benefits to health, productivity and energy savings.

The biggest advantage of daylight saving time is that it provides an extra hour of light in the late afternoon or evening, depending on time of year, for sports, shopping or eating outside. However, exposure to light later into the evening for almost eight months during daylight saving time comes at a price. This extended evening light delays the brain’s release of melatonin, the hormone that promotes drowsiness, which in turn interferes with sleep and causes us to sleep less overall.

Because puberty also causes melatonin to be released later at night, meaning that teenagers have a delay in the natural signal that helps them fall asleep, adolescents are particularly susceptible to sleep problems from the extended evening light. This shift in melatonin during puberty lasts into our 20s.

The ‘western edge’ effect

Geography can also make a difference in how daylight saving time affects people. One study showed that people living on the western edge of a time zone, who get light later in the morning and later in the evening, got less sleep than their counterparts on the eastern edge of a time zone.

This study found that western-edge residents had higher rates of obesity, diabetes, heart disease and breast cancer, as well as lower per capita income and higher health care costs. Other research has found that rates of certain other cancers are higher on the western edge of a time zone.

Scientists believe that these health problems may result from a combination of chronic sleep deprivation and “circadian misalignment.” Circadian misalignment refers to a mismatch in timing between our biological rhythms and the outside world. In other words, the timing of daily work, school or sleep routines is based on the clock, rather than on the sun’s rise and set.

A brief history of daylight saving time

Congress instituted year-round daylight saving time during World War I and World War II, and once again during the energy crisis of the early 1970s. But the popularity of year-round daylight saving time fell from 79% to 42% after it went into effect in January 1974, largely due to safety concerns about children going to school in the dark.

The idea at that time was that having extra light later into the afternoon would save energy by decreasing the need for electric lighting. This idea has since been proved largely inaccurate, as heating needs may increase in the morning in the winter, while air conditioning needs can also increase in the late afternoon in the summer.

After World War II, designating the start and end dates for daylight saving time fell to state governments. Because this created many railroad scheduling and safety problems, however, Congress passed the Uniform Time Act in 1966. This law set the nationwide dates of daylight saving time from the last Sunday in April until the last Sunday in October. In 2007, Congress amended the act to expand the period in which daylight saving time is in effect from the second Sunday in March to the first Sunday in November – dates that remain in effect today.

But the Uniform Time Act does allow states and territories to opt out of daylight saving time. Arizona and Hawaii are on permanent standard time, along with Puerto Rico, the U.S. Virgin Islands, Northern Mariana Islands, Guam and American Samoa.

A shifting landscape

As of March 2024, 17 states have passed laws to adopt year-round daylight saving time. But federal law requires that they need to wait for Congress, and in some cases also neighboring states, to act. More than two dozen states introduced legislation related to the clock change in 2023, but no laws were passed.

Meanwhile, proposed legislation and resolutions for permanent standard time have increased from 15% in 2021 to 37% in 2024.

In March 2022, the U.S. Senate passed the Sunshine Protection Act  in a bid to make daylight saving time permanent. But the House did not move forward with this legislation. Florida Sen. Marco Rubio reintroduced the bill on March 1, 2023, but this bill has not progressed.

The spike in activity among states seeking to break from these twice-yearly changes reflects how more people are recognizing the downsides of this practice. Now, it’s in the hands of legislators to decide whether to end the time shift altogether and to either choose a full year of having clocks more aligned with the sun or to artificially extend the day for more than half the year, for better or for worse.

My research has focused on the impact of treating sleep disorders on neurological disease, and in autism, although I have also become involved in recent years in mitigating vaccine hesitancy and enhancing climate change communication. I hold an endowed chair, the Burry Chair in Cognitive Childhood Development and serve as Vice Chair for Academic Affairs in our Department of Neurology. In addition to conducting my own NIH and foundation-funded patient-oriented research, I have taken an active role in facilitating patient-oriented research through my involvement as Director of Clinical Translational Research for the Vanderbilt Kennedy Center for Developmental Disabilities. I direct the Vanderbilt Sleep Disorders Division. My pursuits outside of work involve being a national moderator for Braver Angels, focused on bridging the political divide. I am also an active member of Toastmasters International.
