Research & Evidence

We Don't Ask You to Believe.
We Show You the Data.

Our work is grounded in decades of clinical research, Harvard Medical School studies, and 5,000 years of empirical observation.

Research Leadership

Tulsi leads research at Harvard Medical School's yoga and meditation research center, where she studies the measurable physiological effects of practices that have been used for millennia.

Her work focuses on how yoga, meditation, and Ayurvedic protocols affect biomarkers in patients with chronic conditions — including cancer, neurodegenerative diseases, and post-viral syndromes like long COVID.

"The ancient practitioners didn't have MRI machines, but they mapped the nervous system with extraordinary precision. Modern science is confirming what they described thousands of years ago."
Research Areas

What the Evidence Shows

Nervous System Regulation

Specific breathwork protocols measurably shift autonomic nervous system balance within minutes. We use these in every talk, retreat, and 1:1 session.

Meditation & Brain Structure

Long-term meditation practice correlates with increased cortical thickness, improved working memory, and reduced amygdala reactivity. The brain changes shape.

Ayurvedic Constitution

Emerging research supports the Ayurvedic model of individual constitution (prakriti) as a framework for personalized wellness — centuries before "precision medicine" existed.

Chronic Conditions

Yoga and Ayurvedic interventions show measurable benefits for cancer-related fatigue, Parkinson's motor symptoms, and long COVID recovery in controlled studies.

Our Approach

Where Ancient Meets Evidence

We don't cherry-pick studies to validate what we already believe. We start with the classical teachings — refined over 5,000 years of human observation — and we test them against modern standards of evidence. When the data supports the practice, we teach it with confidence. When it doesn't, we say so.

This is what makes our work different from both the wellness industry (which often ignores evidence) and conventional medicine (which often ignores tradition). The most powerful interventions live at the intersection.

Every protocol we design — whether for a Fortune 500 keynote or a 1:1 client — is built on this foundation: classical wisdom, rigorously examined, practically applied.

Published Studies

Read the Research

Peer-reviewed studies on the practices we teach — from meditation and breathwork to yoga and lifestyle intervention.

Advanced Meditation & Metabolic Health

8-day advanced meditation retreat with a vegan diet significantly elevated anti-inflammatory acylglycines and lowered atherogenic lipid markers.

Meditation & Genomic Immune Activation

Gene expression analysis showed significant up-regulation of ~220 immune-related genes — particularly interferon pathways — without triggering inflammation.

Advanced Meditation, Inflammation & Metabolic Health

The Samyama intervention correlated with lower HbA1c, systemic inflammation, and improved lipid profiles, alongside sustained enhancements in mental health.
