Year-round Daylight-Saving Time could bring darker mornings and health concerns

WILMINGTON, NC (WWAY) — Congress is considering a change that could keep Daylight Saving Time in place year-round. But health experts warn the proposal could have unintended consequences, including disruptions to sleep patterns and concerns for students who may have to travel to school in the dark during winter months.

A sunrise at Wrightsville Beach during Daylight Saving Time in April shows the sun coming up around 6 a.m. But under a year-round Daylight-Saving Time schedule, winter mornings would look very different, with the sun rising later while sunsets would come later in the evening.

Health experts say that shift could have an impact beyond just changing the clock.

Rand Pennington with Novant Health says permanent Daylight-Saving Time could affect the body’s natural circadian rhythm — the internal clock that helps regulate sleep patterns.

“When you’re not exposed to that morning light, there is evidence that you don’t sleep as well because people stay up later and then they have trouble getting up in the morning,” Pennington said.

Pennington says a lack of morning sunlight can also be linked to other health concerns, including obesity, diabetes, and mental health challenges. He says morning light is often used as a treatment for seasonal affective disorder and depression.

“If people have less access to that morning sun, there could be a higher risk of depression,” Pennington said.

The possible change could also impact students who rely on early morning transportation. At New Hanover High School, some students could find themselves walking to school or waiting for the bus before sunrise during the winter months.

Parent Alicia Hamilton supports changing the current system but says she has concerns about safety.

“More precaution measures need to be taken to ensure my kids’ safety if it passes,” Hamilton said.

Her daughter, student Katherine Hamilton, says walking outside in complete darkness could create challenges.

“You could trip on a rock and no one is there to help you because it’s so dark out,” Katherine said.

Experts recommend parents take extra safety precautions if children are traveling before sunrise, including wearing bright or reflective clothing, waiting in well-lit areas, and traveling with others when possible.

Katherine says a simple flashlight or glowstick on a backpack can also help students stay visible during darker mornings.
