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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Breathing Group 1
Arm 1 will receive an 8-week remotely delivered intervention that consists of a set of breathing practices through 60-minute weekly virtual group sessions (1day/week) with a 20-minute daily home sessions (in between weekly sessions; 6 days/week).
|
The 8-week breathwork intervention incorporates a set of breathing practices under the guidance of a certified yoga teacher.
|
Active Comparator: Breathing Group 2
Arm 2 will receive an 8-week remotely delivered intervention that consists of slow breathing practices through 60-minute weekly virtual group sessions (1day/week) with a 20-minute daily home sessions (in between weekly sessions; 6 days/week).
|
The 8-week breathwork intervention incorporates a set of slow breathing practices under the guidance of a certified yoga teacher.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Sleep efficiency (SE)
Time Frame: 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.
|
12 weeks (8-week interventions and 2 weeks pre- and post-intervention period).
|
Wake after sleep onset (WASO)
Time Frame: 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.
|
12 weeks (8-week interventions and 2 weeks pre- and post-intervention period).
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Total sleep time (TST)
Time Frame: 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.
|
12 weeks (8-week interventions and 2 weeks pre- and post-intervention period).
|
Sleep latency (SL)
Time Frame: 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.
|
12 weeks (8-week interventions and 2 weeks pre- and post-intervention period).
|
Pittsburgh Sleep Quality Index (PSQI)
Time Frame: 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.
|
During 2 weeks pre-intervention and 2 weeks post-intervention period
|
36-Item Short Form Survey Instrument (SF-36)
Time Frame: 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.
|
During 2 weeks pre-intervention and 2 weeks post-intervention period
|
Perceived Stress Scale (PSS)
Time Frame: 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.
|
During 2 weeks pre-intervention and 2 weeks post-intervention period
