Brief summary
The purpose of this research study is to determine the influence of a regular yogic breathing practice on sleep, and to find out primarily if a regular practice of 8-week yogic breathing would enhance sleep quality as well as if it would improve participant's quality of life, and reduce existing stress. Study participants will be randomized into two arms for different breathing practices.
Detailed description
The purpose of this study is to determine the effects of two remotely-delivered 8-week breathing interventions on long term sleep patterns. The study protocol consists of healthy participants (randomized in two breathing groups) undergoing a remotely delivered 8-week intervention and a 12-week sleep tracking period (including 2 week before the intervention, 8 week during the intervention, and 2 week after the intervention). Several sleep metrics will be extracted to characterize long-term sleep patterns and degree of sleep improvement. Participants will also be asked to complete pre- and post-intervention questionnaires. The two remotely delivered interventions will be guided by two separate certified experienced yoga teachers. Both interventions will include 60-minute weekly group virtual sessions (1day/week) with a 20-minute daily home sessions (in between weekly sessions; 6 days/week) using home-aid practice materials.
Interventions
BEHAVIORALBreathing Group 1
The 8-week breathwork intervention incorporates a set of breathing practices under the guidance of a certified yoga teacher.
BEHAVIORALBreathing Group 2
The 8-week breathwork intervention incorporates a set of slow breathing practices under the guidance of a certified yoga teacher.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sleep efficiency (SE) | 12 weeks (8-week interventions and 2 weeks pre- and post-intervention period). | SE is a measure ranging from 0 to 100% indicating the percentage time spent asleep relative to total time in bed. SE will be extracted during a 12-week period to then compute changes in SE. |
| Wake after sleep onset (WASO) | 12 weeks (8-week interventions and 2 weeks pre- and post-intervention period). | WASO is the percentage of time spent awake during the remainder of the sleep period, after the first sleep onset. WASO will be extracted during a 12-week period to then compute changes in WASO. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pittsburgh Sleep Quality Index (PSQI) | During 2 weeks pre-intervention and 2 weeks post-intervention period | PSQI is a self-reported questionnaire that is used to assess sleep quality. PSQI scores range from 0 to 21, with higher scores indicating worse outcome. |
| Total sleep time (TST) | 12 weeks (8-week interventions and 2 weeks pre- and post-intervention period). | TST is the total time spent asleep. TST will be extracted during a 12-week period to then compute changes in TST. |
| Perceived Stress Scale (PSS) | During 2 weeks pre-intervention and 2 weeks post-intervention period | PSS is a self-reported questionnaire that is used to measure the perception of stress. PSS scores range from 10 to 40, with higher scores indicating worse outcome. |
| 36-Item Short Form Survey Instrument (SF-36) | During 2 weeks pre-intervention and 2 weeks post-intervention period | SF-36 is a self-reported questionnaire that is used to assess overall health. SF-36 scores range from 0 to 100, with higher scores indicating better health status. |
| Sleep latency (SL) | 12 weeks (8-week interventions and 2 weeks pre- and post-intervention period). | SL is defined by the number of minutes spent awake in bed, prior to first sleep onset. SL will be extracted during a 12-week period to then compute changes in SL. |
