Brief Summary:
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 hearts ability to recover from a given activity
The investigators propose to study the effect of the WHOOP Strap 20 device on sleep perception and perform a methodological study to validate the accuracy of the the WHOOP Strap 20 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

Detailed Description:
Polysomnography PSG is still considered the gold standard for measuring sleep parameters such as total sleep time sleep efficiency and sleep stages 6 However PSG suffers from key limiting factors for routine care applications irrespective of setting eg home acute setting and long term setting Some of the key limitations of PSG are the high cost arduous application intrusiveness to sleep and requirement of sleep lab and dedicated infrastructure Wearable technologies could provide a viable alternative to PSG We are proposing to perform a methodological study aimed at validating the accuracy of WHOOP Strap 20 to measure sleep quantity and sleep quality in ambulatory subjects We will measure sleep by both WHOOP Strap 20 and PSG in healthy volunteers age 18 - 45 years without self-reported sleep disorders or chronic disabling medical conditions
In ambulatory patients sleep is usually assessed by the American Academy of Sleep Medicine guidelines which derives from the Rechtschaffen and Kales RK method with good to excellent inter-observer reliability for assessing sleep in the same population but the Cohens K range is still 068 to 082 and much lower for non rapid eye movement NREM sleep stage 1 N1 To account for such inter- and intra-rater reliability issues with the PSG gold-standard we will only consider sleep stages that are unequivocally scored as a particular stage light NREM slow wave sleep SWS or REM sleep R sleep by two different observers
Additionally while there are many devices available to healthy individuals to measure heart rate there arent many available that provide a daily heart rate variability statistic Heart rate variability can be defined as the variation over time of the period between consecutive heart beats This is due to the balancing regulation effects of the parasympathetic PNS and sympathetic SNS actions of the autonomic nervous system ANS Increased SNS action results in a fight or flight response leading to an accelerated heart rate while increased PNS activity results in a rest and digest response leading to a decelerated heart rate The increased variability of heart rate HR is an indication of the ANS control on HR and the hearts ability to respond WHOOP Strap 20 provides users with real-time HR and a daily HRV statistic that is included in other variables calculated measuring daily strain and recovery statistics We will measure HR and HRV by both WHOOP Strap 20 and EKG leads in healthy volunteers ages 18-45 years without chronic disabling medical conditions
