This study aims to contribute uniquely to stress, longevity, and mental health research in two ways: by identifying clear protocols of breath-based yoga-meditative practice based on original materials; that are subsequently assessed with established scientific stress, biochemical immunity and longevity markers, and validated psychological measures that relate to mental health.
This study aims to contribute uniquely to stress, longevity, and mental health research in two ways: by identifying clear protocols of breath-based yoga-meditative practice based on original materials; that are subsequently assessed with established scientific stress markers across the sympathetic-adreno-medullar (SAM) axis, biochemical immunity and longevity markers, and validated psychological measures as related to mental health. The study couples emic perspectives from the traditional yoga knowledge base, both textual and practice, with empirical measures from science as an opportunity to bridge these worlds as a first known study of hatha yoga to be tackled by the means and methods of biocultural anthropology. It therefore highlights the importance of context and detail in terms of assessing human behavioral practices, where accuracy in terms of definitions, technique detail, and original purported intentions and outcomes are addressed as relevant when measuring and explaining empirical outcomes under modern research mixed methods.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Active Study Group | Experimental | Participants randomized to the Active Study Group are asked to follow a daily routine of the three protocols of psycho-physical yoga component techniques: Slow Engaged Dynamic Asana (SEDA), Breath Regulated Engaged Meditation (BREM), Sound Heart Engaged Meditation (SHEM). This intervention involves more hours in daily practice to equate to a "high dose" of breath and meditative techniques. |
|
| Active Control | Active Comparator | Participants randomized to the Active Control study arm are asked to follow a daily routine of low-to mid-intensity body posture practice that is body-based and has minimal breath or meditative elements. This intervention involves fewer hours in daily practice to equate to a "medium dose" of body focused techniques |
|
| Passive Control | No Intervention | Participants randomized to the Passive Control study arm do not receive a study intervention. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| High Dose Yoga | Other | Participants engage in an intensive full yoga practice of hatha breath-based practices and inner meditative techniques along with body-based asana. Intensive level uses breath, management of abdomen, inner focus in all practices. The "high dose" of yoga is an interpretation of the Translational Model of Yoga (TMY) and Yoga Process formula, both developed in this study's cultural research: a systematized psycho-physical yoga method of Hatha Zone (HZ) focus (below-navel, exhale, inner focus), incorporating key components of practice-focus-surrender (PFS) approach and repeat-engage-trust (RET) elements. |
