Brief Summary

This study aims to investigate the effect of a 15-minute meditation practice on sleep architecture and high-frequency Heart Rate Variability (HF-HRV), as well as cognitive performance after both a well-rested and sleep-deprived night.

Detailed Description

Sleep is physiologically important for memory consolidation, mood and hormonal regulation, and maintaining low levels of systemic inflammation. However, a substantial proportion of people are reported to regularly sleep less than the recommended 7-9 hours a night. Meditation may be a means to mitigate the negative effects of sleep deprivation, as many types of meditations are associated with increasing high-frequency heart rate variability (HF-HRV), which is an index of parasympathetic control of the heart. Greater parasympathetic drive may be associated with physiological buffering of the detrimental effects of sleep deprivation.

The investigators want to conduct a prospective cohort study where subjects are asked to learn and practice a 15-minute meditation (shoonya meditation) or continue their usual routine. Subjects will be asked to complete some cognitive tests before and after a night of sleep and a night of sleep deprivation. During the night of sleep, participants will undergo polysomnography recording for sleep architecture and quality.

The intervention group will be asked to undergo these same study procedures after 2 months of meditation practice. The control group, which continues their usual routine, will only undergo one visit.

Arm && Interventions

Group	Intervention	Description
Nap Practitioners	Nap Practitioners	This is an observational arm of regular nappers. Individuals that take naps at least two times a week will be invited to undergo all of the study procedures for one weekend of data collection.
Shoonya Meditators	Shoonya Meditation	This is intervention arm. Participants will learn and practice the fifteen minute shoonya meditation - described as a process of conscious non-doing- and shakti chalana kriya, which is a set of breathing exercises designed as a preparatory practice to shoonya meditation. Participants will practice shoonya meditation twice a day for two months. A weekend of data collection will happen at baseline and two months after they learn the practice.

Primary Outcome Measures

Name	Time	Method
Error frequency Change: Go-No Go Task	2 months post learning meditation	The primary outcome is the difference in number of commission and omission errors on the Go-No Go task. The difference in scores pre- and post-sleep deprivation will be analyzed between the control and intervention group.

Secondary Outcome Measures

Name	Time	Method
Reaction Time Change: Go-No Go	2 months post learning meditation	The difference in reaction times on the Go-No Go task. The difference in scores pre- and post-sleep deprivation will compared between the control and intervention groups.
