As Americans prepare to push their clocks forward this weekend, many may groan at the prospect of losing an hour of sleep. However, the consequences of Daylight Saving Time (DST) extend far beyond a groggy morning. Researchers warn that this biannual disruption takes a significant toll on public health, safety, and even the economy—raising the question of whether it’s time to end this outdated practice.
The Case Against DST
For decades, DST has been promoted as a measure to conserve energy. But scientists, including Virginia Tech biologist Professor Carla Finkielstein, argue that the supposed benefits of DST are dubious at best—and at worst, the practice endangers public well-being.
“Daylight Saving Time disrupts our natural biological rhythms by limiting morning sunlight exposure,” Finkielstein explains. “This misalignment with our internal clocks contributes to sleep deprivation, increases health risks, and reduces overall productivity.”
Finkielstein and her colleagues at the Society for Research in Biological Rhythms advocate for a permanent shift to standard time, citing mounting evidence of DST’s negative health effects.
A Policy Rooted in the Past
The origins of DST date back to World War I, when Germany first implemented the practice in 1916 to conserve fuel. The U.S. followed suit in 1918 but abandoned it soon after due to widespread opposition. It wasn’t until 1966, under pressure from the transportation industry, that Congress mandated uniform DST nationwide.
Over the years, DST has expanded from six months (May–October) to its current eight-month stretch (March–November), despite mounting scientific evidence suggesting its harmful effects outweigh any potential benefits. Today, Arizona and Hawaii, along with U.S. territories like Puerto Rico and Guam, wisely opt out of the system altogether.
The Hidden Costs of DST
The time shift isn’t just a minor inconvenience—it has been linked to a cascade of serious health and safety issues. Research shows that in the weeks following the switch, the risk of heart attacks, strokes, and fatal accidents spikes. Additionally:
- A 19% increase in heart attacks occurs after the shift.
- A 5% rise in Type 2 diabetes has been linked to long-term DST exposure.
- A 12% increase in cancer rates is observed among women, while men see a 9% increase.
- More traffic fatalities, particularly among early-morning commuters and children walking to school in the dark.
“This one-hour switch essentially places us in an artificial time zone,” Finkielstein says. “That mismatch between our internal clocks and the sun has severe consequences for our health.”
Public Resistance: A Lesson from the Past
Some argue that a permanent switch to DST would be preferable to abolishing it entirely. However, history suggests otherwise. In the 1970s, during the Arab oil embargo, Congress experimented with year-round DST to conserve energy. While initially popular, public support plummeted when dark winter mornings led to an increase in school bus accidents and drowsy drivers.
The backlash was swift—Congress repealed the change in a near-unanimous vote of 383–16. “That decision should have settled the debate,” Finkielstein notes. “Standard time is the only option that aligns with our biological needs.”
A Political Battle
Despite overwhelming evidence against DST, efforts to abolish it have faced bureaucratic hurdles. Just this week, Representative Celeste Maloy of Utah introduced a bill that would allow states to opt out of DST altogether, reigniting the debate over whether federal intervention is necessary.
As policymakers weigh their options, Americans are left to cope with the biannual disruption. Experts suggest easing the transition by maintaining consistent sleep schedules and avoiding early-morning commutes when possible. But for many, the real solution lies in finally abandoning DST for good.
“Fighting against our internal clocks is a losing battle,” Finkielstein warns. “If we truly value our health and safety, it’s time to leave Daylight Saving Time in the past where it belongs.”

The only way to end DST is through the voice of the people. We must push and push hard on our state and federal representatives to end the nonsense!
LEAVE THE CLOCKS ALONE!!! WE DONT NEED IT TURNING DARK AT 4PM!!!!! CANT EVEN GO FOR A SUNDAY DRIVE BECAUSE CANT SEE ANYTHING IN THE DARK!!!!!!!! WINTER LOCKDOWN SUCKS!!! LEAVE THE CLOCKS ALONE THE WAY IT IS, STAYING LIGHT TILL 845PM!!!!!!!
I agree with you, leave it alone. President Trump even said it’s 50, 50.
Why should those of us who love having a life in the summer, while being winter prisoners, have to suffer by the other half.
They get winter the way they like it, and those of us who love long summer days, should get what we like.
Standard Time is the best time for everyone. Children in particular that have
to walk to school in the dark. Driving in the dark is also not good. Some people have to start out early and come back late, so they never see the sun.
Standard Time is best!
What about the children that would like to stay out and play longer, of a beautiful Spring, Summer, Autumn Day. We could maybe go back to April and October, instead of March and November.
Compromise,and let those who like DST have something. It’s just such a good thing in the summer for a lot of people.
I vote STANDARD time!!!!!
It only does that on the first day for me.
LEAVE RHE TIME THE WAY IT IS NOW! TURNING DARK AT 4PM IS CRAP! ALL THESE HEALTH STUFF IS A LOT OF CRAP! ITS FOR ONE DAY AND THEN U RESUME NORMALCY!
Exactly right…. It is only for one day that you loose an hour of sleep. I sure don’t hear anybody complaining, about that extra hour. They get in the fall. Whenever somebody doesn’t like something, Health is always brought into it to make the case.
I remember that year we didn’t change the clocks back.
When I went to school class were 9 am-3 pm. no one walked in the dark. now classes start @ 8am and end @ 2:30. Change the school hours if you don’t want the children to walk in the dark. besides child now a day get driving to school by their Parents, no one hardly walks to school.
