Annoyed with time changes in the fall and spring? So is President-elect Donald Trump. On Friday, Trump posted on Truth Social that the “Republican Party will use its best efforts to eliminate Daylight Saving Time” because it is “inconvenient, and very costly to our Nation.”
Ending daylight saving time would also not be that original—two thirds of countries do not have it. Americans do seem to be split on the issue. In a 2019 poll, 7 out of 10 Americans said they did not like the biannual switches, but 4 in 10 wanted a fixed standard time and 3 in 10 wanted daylight saving time.
Even putting aside the economic argument for ending daylight saving time, some research suggests that the practice of putting the clock one hour ahead in the spring can negatively impact peoples’ mental health. When our internal clock is thrown off and we get less sleep, our mood can be impacted, leading us to feel less focused and potentially more depressed. This lack of focus can also be deadly—a February 2020 study that looked at two decades’ worth of traffic accidents found that there was a 6 percent increase in the risk of fatal traffic accidents in the week following daylight saving time in the United States.
In October 2020, the American Academy of Sleep Medicine, a professional society that represents medical specialists who focus on sleep medicine, even issued a statement in support of ending daylight saving time in favor of a fixed year-round schedule:
It is the position of the AASM that the U.S. should eliminate seasonal time changes in favor of a national, fixed, year-round time. Current evidence best supports the adoption of year-round standard time, which aligns best with human circadian biology and provides distinct benefits for public health and safety.
Unlike Trump’s recent false claims linking vaccines with autism diagnoses, his support of ending daylight saving time is actually backed by science.
