Physiological persona differences based on stress and inflammation between meditators and healthy controls

Area of Science:

• Integrative Medicine
• Psychoneuroimmunology
• Lifestyle Medicine

Background:

• Yoga and meditation are widely recommended for health maintenance and chronic disease management.
• A hypothesis suggests distinct physiological and psychological profiles between regular yoga practitioners and non-practitioners.
• Understanding these differences can inform health recommendations and personalized interventions.

Purpose of the Study:

• To scientifically investigate the hypothesis of differing personas in regular yoga practitioners versus non-practitioners.
• To analyze baseline physiological characteristics, stress, and inflammation levels in long-term meditators, short-term meditators, and healthy controls.
• To compare plasma levels of key stress and inflammatory markers across these groups.

Main Methods:

• Retrospective analysis of 97 male participants categorized into long-term meditators (LTMs, >5 years), short-term meditators (STMs, 2-week intervention), and healthy controls.
• Assessment of baseline plasma levels of cortisol, β-endorphin (β-Ed), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α).
• Measurement of body mass index (BMI), systolic blood pressure (SBP), and diastolic blood pressure (DBP) in all groups.

Main Results:

• Significant differences (p<0.05) were observed at baseline across LTMs, STMs, and healthy controls for stress and inflammatory markers.
• Body mass index and systolic blood pressure also showed significant variations among the three groups.
• Long-term meditators exhibited a more favorable stress and inflammation profile compared to short-term meditators and controls.

Conclusions:

• Regular yoga-meditation practice is associated with improved stress and inflammation status.
• Long-term practitioners demonstrate superior physiological and inflammatory markers compared to short-term practitioners and healthy individuals.
• These findings support the integration of yoga and meditation into lifestyle interventions for enhanced well-being.
