Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
To examine the effects of a 4-week vinyasa yoga program compared to a non-active control condition on subjective and objective sleep-related outcomes in adults who report insomnia symptoms.
To examine the effects of a 4-week vinyasa yoga program compared to a non-active control on cardiovascular health.
To examine the effects of a single session of vinyasa yoga compared to a non-active control condition on sleep- and cardiovascular-related outcomes collected overnight.
Researchers will compare the yoga group and the non-active control group to see if there are any improvements in sleep and cardiovascular health.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
All groups will complete an initial in-person experimental session during the early evening: those in the vinyasa yoga group will be guided through a supervised vinyasa yoga session and those in the non-active control group will complete a quiet rest session. Participants will be provided an Actiwatch and heart rate monitor to measure acute experimental effects on sleep and nocturnal heart rate variability.
Following the initial supervised session, those in the vinyasa yoga intervention will be provided with a yoga mat and a standardized video and asked to practice 3 times per week for 4 weeks; compliance will be monitored by an online log. The non-active control group will not receive any yoga intervention and will be asked to avoid starting a new exercise routine.
Following the 4-week intervention, all participants will complete post-intervention sleep and cardiovascular assessments following the same procedures used at baseline.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Vinyasa yoga group
The vinyasa yoga practice will be 60 minutes in duration and includes standing, seated, and supine postures in the following sequences in order: integration, sun salutations, crescent lunge series, balancing, standing, back bending, and restorative series. Participants will be instructed to follow the cues provided in the video and to take any necessary modifications to make each yoga pose more accessible. Vinyasa yoga intervention level 1 will be performed for week 1, level 2 will be performed for week 2, and level 3 will be performed for weeks 3 and 4 of the intervention.
Vinyasa yoga group
Participants will be instructed to perform a pre-recorded 60-minute vinyasa yoga session 3 times a week for 4 weeks.
Non-active control group
The participants in the non-active control condition will serve as a control group. They will be asked to maintain their current lifestyle habits and refrain from starting a new exercise and/or yoga program. A staff member will contact each participant weekly to check in and review any changes to their medical history or activity levels.
Non-active control group
Participants will be instructed to sit quietly for 60 minutes and watch a nature documentary during this time. The participants will be asked to maintain their current lifestyle habits and refrain from starting a new exercise and/or yoga program.
