The daytime habit that 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, experiencing deeper sleep during the first part of the night.
• The research, involving 89 adults over 500 days using light sensors and sleep trackers, suggests that morning light exposure helps regulate the body's internal clock and promotes healthier sleep patterns.
• Clinical psychologist Jennifer Martin emphasized the importance of morning sunlight for maintaining a consistent sleep-wake cycle and recommended limiting bright light exposure in the evening to improve sleep quality.
• The study showed an association between daytime light exposure and sleep but did not establish a direct causal relationship and had limitations such as measuring light at the wrist rather than the eyes.
• Experts advise adults to aim for at least seven hours of sleep nightly and seek professional help if sleep problems persist, highlighting the role of consistent wake times and light management in sleep health.
