Spending more time in bright daylight could transform your sleep, according to new study

Key Points:

• A University of Manchester study found that adults exposed to brighter and more consistent daylight tend to fall asleep and wake up earlier, with increased deep sleep during the early night.
• The research, involving 89 adults over 500+ days using light sensors and sleep trackers, suggests that morning light helps regulate the body's internal clock and promotes healthier sleep patterns.
• Clinical psychologist Jennifer Martin emphasized the importance of morning sunlight exposure and limiting bright light in the evening to maintain a consistent sleep-wake cycle and improve sleep quality.
• The study showed an association but did not establish causation, and limitations included measuring light exposure via wrist devices rather than directly at the eyes and not controlling for other lifestyle factors.
• Experts recommend at least seven hours of sleep nightly and consulting a sleep specialist if sleep issues persist, while encouraging regular morning light exposure for better sleep health.
