Getting more bright daylight during the day may be a simple way to improve sleep at night, according to new research. The study suggests that people with brighter and more regular daytime light exposure tended to fall asleep earlier and spend more time in deep sleep.
Researchers at the University of Manchester led the study, which included 89 adults. Based on the findings, consistent exposure to daylight appears to play an important role in sleep timing, adding to evidence that the body’s internal clock responds strongly to natural light patterns.
The results point to a possible daytime habit that could support better rest without focusing only on nighttime routines. While many sleep tips center on limiting screens or improving bedroom conditions, the study highlights how what happens during the day may also shape sleep quality.
The research adds to growing interest in the connection between light exposure and circadian rhythm. Although more study may be needed, the findings suggest that spending more time in bright daylight could be linked to earlier sleep and deeper rest.
