Mind-Body Medicine

Documented biological mechanisms:

Autonomic nervous system: mind-body practices selectively activate the parasympathetic system (raise HRV, reduce heart rate and blood pressure), antagonising chronic sympathetic activation of modern stress. HPA axis: Jon Kabat-Zinn's MBSR studies show significant reduction of chronic cortisol and normalisation of the diurnal curve. Inflammation: meditation consistently reduces IL-6, TNF-α, and CRP in meta-analyses (Black & Slavich 2016). Epigenetics: Dean Ornish's study (2008) showed that a 3-month intensive lifestyle intervention programme (including meditation) modified expression of 500+ prostate-cancer-related genes. Biological age: pilot studies with advanced meditators show reduced biological age on epigenetic clocks.

Evidence-based protocols: MBSR (Mindfulness-Based Stress Reduction): standardised 8-week programme, 2.5 h weekly + 45 min/day of practice. Wim Hof Method: breathing + cold exposure. Kox/Pickkers studies (2014) show that trained practitioners can voluntarily activate the sympathetic nervous system and modulate inflammatory response to endotoxin. Heart-rate coherence: 6-bpm breathing synchronising HRV with heart rate. Applicable any time of day (5-15 min).

Mind-body medicine does not replace pharmacology when indicated; but it is the longevity complement with the best cost-benefit ratio and no side effects.
