This study is being conducted in order to understand more about how the body responds to a
mind/body practice called yoga nidra. Results from this study will be used to inform the
design of future studies that investigate the effects of yoga nidra on sleep quality and
insomnia.
Yoga nidra is a simple guided meditation technique that involves lying still on a mattress
while listening to a voice. Participants will follow simple instructions that involve
becoming aware of their body and breath, as well as various memories, emotions, and images.
This practice is not religious in nature. The investigators do not believe it will conflict
with any religious beliefs. The goal of this practice is to help get rid of mental, physical
and emotional tensions.

---|---|---|---|---|
Primary | Change in EEG power (uV^2/Hz) of alpha brainwaves (defined by frequencies between 8-12 Hz) measured from the occipital region of the scalp. | Average change in alpha power (from visit 1 to visit 2) will be compared for intervention and control groups. Other frequency bands (delta, beta, and theta) will be measured as well. EEG measurements will be collected from the F3, C3, and O1 locations on the scalp. | 90 minutes | |
Secondary | Change in time to sleep onset | Average change in time to sleep onset (SOL) from visit 1 to visit 2, will be compared for intervention and control groups. The EEG montage follows American Academy of Sleep Medicine (AASM) guidelines for sleep measurement, and includes sensors placed in the following locations: ChinZ, Chin1, E1, E2, F3, C3, and O1, with (contralateral) reference and ground electrodes clipped onto the right and left earlobes, respectively. | 90 minutes | |
Secondary | Change in heart rate variability (HRV) parameters | The average change (visit 1 to visit 2) in two HRV parameters (root mean square of successive differences between normal-to-normal intervals (RMSSD, ms); and high frequency power (HF, ms^2)) will be compared for intervention and control groups. | 90 minutes | |
Secondary | Change in respiration rate | Average change in respiratory rate (visit 1 to visit 2) will be compared for intervention and control groups. | 90 minutes | |
Secondary | Feasibility: Credibility of Intervention | After the intervention, participants will rate perceived credibility of the intervention for its use in producing sleep. | Rating will occur immediately after their visit | |
Secondary | Feasibility: Acceptability of Intervention | Acceptability will be determined using recruitment and dropout rates | Seven months |
