As a new presidential administration takes office, political momentum to end seasonal time changes is building. President Donald Trump stated his support for ending daylight saving time, drawing media and policymakers' attention to reconsider the benefits of ending the biannual clock adjustment. The Coalition for Permanent Standard Time, whose organisational members include the American Academy of Sleep Medicine, calls on policymakers to abolish seasonal time changes and adopt permanent standard time, which follows science and prioritises public health, safety, and efficiency.

The public, too, is ready for change, as shown by a recent AASM survey, which found that half (50%) of Americans support legislation to eliminate seasonal time changes, while only one-fourth (26%) are opposed.

"The switch to daylight saving time in the spring may seem harmless, but the reality is far more complicated," said Jay Pea, co-chair of the coalition and president of Save Standard Time. "It disrupts our body clocks, affects our sleep quality, and increases the risk of avoidable health and safety incidents, such as motor vehicle accidents, cardiovascular events, and even workplace errors in the days following the time change. Adopting permanent standard time, on the other hand, offers a better solution for year-round well-being.”

Why Standard Time Is the Healthier Choice

Standard time aligns more closely with our body’s natural circadian rhythms, which regulate sleep-wake cycles. It offers more sunlight in the morning, helping people wake up and feel more alert, while the evenings gradually become dark earlier, signalling to our bodies that it's time to wind down. This natural alignment supports more restful and consistent sleep. When daylight saving time is in effect, evening light exposure is prolonged, which can delay bedtime and disrupt sleep patterns. The increased morning darkness, particularly in winter if daylight saving time were permanent, would create additional challenges, such as unsafe conditions for commuters and children heading to school.

"We’ve tried permanent daylight saving time before, and it didn’t work," Pea noted. "This time, let’s get it right by prioritising health and safety with permanent standard time."

Tips for Transitioning to Daylight Saving Time

As Americans look to spring forward on March 9, the AASM encourages everyone to take the following steps to minimise the disruption:

About the Coalition for Permanent Standard Time

Established in 2023, the Coalition for Permanent Standard Time is a dedicated group of diverse organisations and individuals that support the elimination of biannual clock change in the United States through the restoration of permanent standard time. The founding organisational members are the American Academy of Sleep Medicine, National Sleep Foundation, Save Standard Time, Sleep Research Society, and Society for Research on Biological Rhythms (ditchDST.com).

About the American Academy of Sleep Medicine

Established in 1975, the AASM is a medical association that advances sleep care and enhances sleep health to improve lives. The AASM membership includes more than 9,500 physicians, scientists, and other health care professionals who help people who have sleep disorders. The AASM also accredits 2,300 sleep centers that are providing the highest quality of sleep care across the country (aasm.org).
