Abstract
This research investigates the impact of light on sleep and circadian rhythm in adolescents and young adults. Light serves as a primary regulator of circadian rhythms, influencing sleep-wake cycles and overall health. By synthesizing findings from various studies, we explore the effects of light intensity, duration, and wavelength on sleep patterns and circadian timing. Studies demonstrate a gradual shift towards later bedtimes during adolescence, potentially linked to changes in circadian timing. Furthermore, research highlights the differential sensitivity to light between pre- to mid-pubertal and late to post-pubertal adolescents, with shorter wavelengths of light exerting a more significant impact on circadian rhythm and sleep architecture. Understanding these dynamics is crucial for designing interventions to promote healthy sleep habits and overall well-being in adolescents and young adults. To investigate our meta-analysis of prior studies, we distributed 50 actigraphy watches to Northwestern students, which tracked their sleep schedule and daily light exposure, in order to identify any variable conclusions or patterns. This investigation aims to contribute valuable insights into the role of light in shaping sleep patterns and circadian rhythms during critical developmental stages.
