  • This study investigates how daily sunlight exposure affects sleep quality the following night, finding that morning sunlight exposure is linked to better sleep, possibly by regulating circadian rhythms.
  • The research involved 103 adults tracking their sunlight and sleep over up to 70 days, and results showed that exposure to sunlight in the morning predicted improved sleep quality.
  • The findings suggest that morning sunlight could be used in sleep improvement strategies and influence policies like daylight saving time, but more research is needed to confirm these effects and explore practical applications.]
