But Abbott says what is very clear is that there are negative health effects linked to shifting the clocks. But one study from 2020 found a 6% rise in fatal car crashes after the spring time change. And I think that probably played a role in that.ĪUBREY: Well, thankfully, no one was hurt in my fender bender. I don't know if that would hold up in court. SABRA ABBOTT: Can you claim daylight savings time was to blame? Probably. She's a neurologist who researches the impacts of timing on our health. I reached out to the director of the circadian medicine clinic at Northwestern University, Dr. Thousands of dollars later, I found myself questioning why this happened. And while this may seem like a coincidence, it turns out that I was involved in a traffic incident the day of the spring forward change as well.ĪUBREY: Yeah. And if I can make my own admission, I was involved in an incident on the Wednesday after the time change last week.ĪUBREY: He collided with another car.
#Daylight saving timing drivers
In addition, when much of the nation is tired and groggy on a single day from losing an hour of sleep - it can lead to a lot of distracted drivers on the road.ĬHUDOW: Traffic accidents after the time change - there's definitely a signal that there's more of those after we change the clocks, just like there are more workplace accidents and such. And with the abrupt change when we spring forward losing that hour, it disrupts our internal clocks in ways that can be harmful. The first rays of morning light help to reset our clock each day. A few years back, three scientists won a Nobel Prize for their work that helped to discover that we have clocks running in literally every cell in our body, some timekeeping mechanism. But what has become clear, Rachel, is that our bodies are super sensitive to time. Or do scientists know why that happens?ĪUBREY: Exactly why isn't nailed down. But still, that is really surprising and disturbing. So the time change wasn't the sole cause but rather the factor that likely put them over the edge.
Why should it cause this large effect?ĪUBREY: He says people who ended up in the hospital with A-fib had other risk factors. I was very surprised because it's just one hour change. JAY CHUDOW: We found that there were more hospitalizations for atrial fibrillation after the spring time change. He compared hospital admissions for a type of heart arrhythmia in the days after the time change compared to the rest of the year. I talked to a cardiologist about this, Jay Chudow at Montefiore Health. What's surprising is that the spring time change is actually linked to an increased incidence of heart attacks and other cardiac events. But don't our bodies just sort of adjust?ĪUBREY: You would think that it's really not a big deal to adjust the clock by one hour, but our bodies kind of tell a different story. But it was just a couple of weeks ago we lost an hour of sleep.
Updated yet, much to my children's chagrin. MARTIN: So I have to admit, there are some clocks in my house I haven't even. And while many scientists agree, there is no compelling reason to switch the clocks twice a year, the big debate is, which is better, having more sunlight in the morning or in the evening? NPR's Allison Aubrey is here to talk about it with us.ĪLLISON AUBREY, BYLINE: Good morning, Rachel.
For that to happen, the House of Representatives would need to pass the measure, too.
Senate voted unanimously earlier this month to make daylight saving time permanent.
