‘Gutfeld!’: Make Daylight saving time permanent
Sean Davis, CEO and co-founder of The Federalist, alongside comedian Joe Machi, passionately advocate for making daylight saving time permanent. Davis humorously claims ‘mornings are stupid,’ emphasizing the desire for afternoon sunlight when more people are awake. Machi highlights the safety and enjoyment of children being able to see in the evening when picked up from after-school activities.

Spending more time in bright daylight could help people fall asleep earlier and get deeper sleep at night, according to new research.
A study led by researchers at the University of Manchester found that adults with brighter and more consistent daytime light exposure tended to fall asleep earlier, wake up earlier and experience more deep sleep during the first part of the night.
The findings, published in the journal NPJ Biological Timing and Sleep, were based on more than 500 days of data collected from 89 adults who wore light sensors and sleep trackers while keeping daily sleep diaries.

Participants who spent more time in brighter daylight generally fell asleep and woke up earlier than those with less light exposure. Those with more consistent daytime light exposure also experienced healthier sleep timing and more deep sleep early in the night, according to the study.
Jennifer Martin, Ph.D., a clinical psychologist and professor at Florida International University’s Herbert Wertheim College of Medicine, said the findings align with what sleep experts already know about how light affects the body’s internal clock.
“Light impacts human sleep through a specific pathway, starting with the eye,” Martin, who was not involved in the study, told Fox News Digital.

“When light hits specific cells in the retina, it communicates to the brain that it’s daytime, meaning we should be alert and active.”
Morning light is especially beneficial because it helps keep the body’s sleep-wake cycle consistent, Martin said. She recommends spending time outdoors early in the day when possible.

“Exposure to sunlight early in the day is really good for healthy sleep,” she said. “Regular morning light helps people feel sleepy around the same time each evening and build a strong sleep routine.”
Limiting bright light in the evening can also help improve sleep, Martin said.

She recommends avoiding bright light during the last couple of hours before bedtime and maintaining a consistent wake-up time each morning.
“Varying your wake time by more than about one hour can lead to feelings of ‘jet lag’ and contribute to trouble with regularly sleeping well,” Martin said.

She added that adults should aim for at least seven hours of sleep each night and seek help from a sleep specialist if sleep problems become chronic.
While the findings suggest brighter daytime light may support healthier sleep, the researchers said the study has several limitations.

They noted that the research found an association between daytime light exposure and sleep patterns but did not prove that one directly caused the other.
The researchers also measured light exposure using wrist-worn devices rather than at the eyes, where light directly influences the body’s internal clock, and did not account for factors such as physical activity or meal timing that could affect sleep.
