(WKYT) – Clocks spring forward this Sunday, and a Kentucky neurologist and state trooper are warning of the risks that come with losing an hour of sleep.
Daylight saving time began as an energy-saving idea nearly 250 years ago, according to Johns Hopkins University. However, today, the centuries-old concept has created new dangers on the road.
Dr. Subhendu Rath, a neurology professor at the University of Kentucky who is board-certified in epilepsy and sleep medicine, says the time change disrupts the body’s internal clock.
“This circadian rhythm regulates our sleep, our hormones, our energy levels, and a large part of that is based on the sunlight and the external light cues,” Rath said.
Rath said that when the body doesn’t get enough sleep, it can affect the front part of the brain, which is responsible for quick decision-making. He said increased rates of errors can raise the risk of accidents while driving.
Rath said those effects can be felt for a few days or a few weeks. He recommends people prepare ahead of the time change and prioritize getting eight hours of sleep.
“One thing which we suggest is going to bed 15 to 30 minutes earlier each night so that the body is kind of expecting this change, and this will help reset the internal body clock,” Rath said.
Drowsy driving a concern on Kentucky roads
Kentucky State Police Trooper Scotty Sharp said drowsy driving is a form of impaired driving.
According to Kentucky’s 2024 Traffic Collision Report, 68 people died in crashes in March, trailing only May, which recorded 71 fatalities.
“Your reaction time significantly decreases when you’re tired, so if you start feeling those heavy eyelids and maybe you’re drifting off, those are signs that you’re getting tired,” Sharp said.
Sharp said a rest stop is a good option for a power nap if a driver begins to feel drowsy behind the wheel.
“Your life and those of the other motorists on the roadway are what’s most important,” Sharp said.
Sharp is also reminding drivers to use their headlights and watch for deer as the sun rises later than usual.
