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.

No Intervention: Control
Participant will lie quietly for 90 minutes. They will be allowed to sleep.
Experimental: Yoga Nidra
Participant will practice yoga nidra (using a recording) during the first 30 minutes of the 90 minute measurement period. Then they will be allowed to sleep.
Other: Yoga Nidra
This is a mind/body technique. Specifically, it is a guided meditation, performed while lying down.
- 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. [ Time Frame: 90 minutes ]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.
- Change in time to sleep onset [ Time Frame: 90 minutes ]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.
- Change in heart rate variability (HRV) parameters [ Time Frame: 90 minutes ]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.
- Change in respiration rate [ Time Frame: 90 minutes ]Average change in respiratory rate (visit 1 to visit 2) will be compared for intervention and control groups.
- Feasibility: Credibility of Intervention [ Time Frame: Rating will occur immediately after their visit ]After the intervention, participants will rate perceived credibility of the intervention for its use in producing sleep.
- Feasibility: Acceptability of Intervention [ Time Frame: Seven months ]Acceptability will be determined using recruitment and dropout rates
