About

The main goal of this study is to determine whether exposure to a narrow band of green light (NBGL) improved sleep quality in healthy subjects.

This is a within-subject study design that examines NBGL effects on sleep onset, sleep fractures (i.e., how many times per night the subjects wake up), total sleep duration, and sleep quality using high-resolution assessments. To complete the study, each participant will complete a 30-day, daily sleep diary while using white light (i.e., being in regular room light) during the last 2 hours of their waking period. This period will be defined as the baseline/control arm of the study. After completing this phase 1, subjects will receive a lamp designed to emit the narrow band of green light and again be asked to complete a 30-day, daily sleep diary, but this timer while using the NBGL light (i.e., being in what appears green light) during the last 2 hours of their waking period. This period will be defined as the active arm of the study. After completing this phase 2,

Full description

Sleep quality will be assessed using the Consensus sleep diary [Carney et al., (2012)] The consensus sleep diary: Standardizing prospective sleep self-monitoring, Sleep Vol.35, No.2, pp.287-302], the latter of which captures total sleep time, sleep latency, wake after sleep onset, number of awakenings, quality, sleep efficiency, and trouble staying awake.
