Significance: 10-15% improvement over 6-8 weeks.
Duration for Effect: 20-30 minutes daily.
9. Increase in Anti-Aging Genes (Sirtuins)
Description: Activates sirtuins, promoting resilience and slowing aging.
How it was gathered: Gene expression analysis studies.
Significance: 15-20% increase in sirtuin activity over 12 weeks.
Duration for Effect: 20-30 minutes daily for 12 weeks.
10. Increase in PEA (Phenylethylamine – Focus Enhancer)
Description: Boosts mental clarity and creativity.
How it was gathered: Urine tests measuring PEA levels.

Significance: 20% increase in serotonin metabolites.
Duration for Effect: 6-8 weeks of daily practice.
12. Regulation of HPA Axis (Stress Response System)
Description: Balances the hypothalamic-pituitary-adrenal axis, reducing stress responses.
How it was gathered: CAR measurements in meditation practitioners.
Significance: 15-20% improvement in HPA axis regulation.
Duration for Effect: 4-8 weeks of consistent meditation.
13. Increase in Beta-Endorphins (Pleasure and Euphoria)
