This study aimed to address this gap by examining the effects of an afternoon daylight intervention on subsequent sleep. Methods: Ten healthy participants (4 males; 19 to 28 years) completed two randomized 3-h afternoon outdoor walks under high-intensity light (HIL; clear goggles) or attenuated light (AL; neutral-density-filtered goggles; ~10 photopic lux) conditions. Light exposure was centered around the estimated crossover between the phase-advancing and phase-delaying portions of the light phase-response curve, individually determined from baseline dim li","pubDate":"2026-10-27","url":"https://www.biorxiv.org/content/10.64898/2026.10.22.761062v1?rss=1"},"indexado":"2026-10-27T21:28:27.096Z"}}
