Spring forward with caution: The time change can cause a “mini-jet lag” effect, disrupting sleep patterns and circadian rhythms.
SAN DIEGO — As millions of Americans prepare to “spring forward” for daylight saving time, health experts are cautioning about the potential negative impacts on physical and mental well-being.
The annual time change, which occurs Sunday at 2 a.m., requires most of the country to move their clocks forward by one hour, potentially disrupting sleep patterns and circadian rhythms.
Emily Manoogian, Ph.D., a scientist at the Salk Institute for Biological Studies specializing in circadian rhythm, warns that the time shift can be more than just an inconvenience.
“Having to wake up in the dark is not only uncomfortable, it’s actually really bad for your health long term,” she explained.
The sudden change in sleep schedule can lead to what Manoogian describes as a “mini-jet lag” effect.
“When you have that one hour shift that we’re all about to experience, it doesn’t feel very good,” Manoogian said. “Your body is having to adjust to that new time.”
Recent studies have highlighted the potential health risks associated with the time change. Research from the Academy of Neurology found an increased risk of stroke in the first two days following the shift to daylight saving time. Additionally, a University of Michigan study reported an elevated risk of heart attacks during this period.
“You’re getting this misalignment of your body’s clock with your environment and you’re forcing it awake an hour earlier before it’s ready.” Manoogian said. “For people on the edge of things, it just pushes them over.”
The time change also raises concerns about road safety. AAA research indicates that drowsy driving, exacerbated by sleep disruption, is a significant factor in traffic fatalities.
“18% of all traffic fatalities between 2017 and 2021 were estimated to involve a drowsy driver, accounting for nearly 30,000 deaths,” Gianella Ghiglino, AAA Public Affairs Specialist, said.
Mental health can also be affected by the time change.
“Waking up with light is a big part of starting our day in a positive way and feeling energized,” Manoogian said. “When you’re fighting that, it really hurts people.”
While there have been discussions about making daylight saving time permanent, Manoogian advises against it, suggesting that standard time is preferable. To mitigate the effects of the time change, she recommends gradually adjusting sleep schedules.
“Go to bed a little earlier and try to wake up maybe 30 minutes earlier on Sunday, then another 30 minutes earlier on Monday, to give your body a little time to catch up,” Manoogian said.
As the debate over daylight saving time continues, experts emphasize the importance of prioritizing sleep and being aware of the potential health risks associated with this annual time shift.
