Summary
This study looked at how daylight and physical activity influence the body's internal clock and sleep. Fifty-one healthy adults aged 18-35 were exposed to different lighting conditions (office light, natural daylight, or daylight with blue-light-blocking glasses) and either rested or hiked for 4 hours. Researchers measured shifts in melatonin onset and sleep quality to understand how these factors affect circadian rhythms.
