Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Polysomnography (PSG) is considered the 'gold standard' for objectively measuring different parameters of sleep, including total sleep time, quality of sleep, and distinguishing between sleep stages. However, PSG is costly, and tends to be burdensome in terms of set-up time and invasiveness during sleep. Wearable sleep-monitoring devices could prove to be a more practical alternative to PSG. Additionally, while EKG leads are typically what is utilized to measure heart rate (HR) and heart rate variability (HRV) throughout the night in a PSG set-up, every day-use HR monitors are also beneficial for individuals to evaluate their cardiovascular activity during different types of physical activities (including every day activities, exercise, and sleep), as well as their heart's ability to "recover" from a given activity. The investigators propose to study the effect of the WHOOP Strap 2.0 device on sleep perception and perform a methodological study to validate the accuracy of the the WHOOP Strap 2.0 device when measuring HR accuracy and HRV accuracy, and sleep quality and quantity with respect to PSG in healthy volunteers with no self-reported sleep disorders or debilitating medical conditions.
