Definition
Exercise produces documented epigenetic changes in muscle, adipose, and blood tissue, contributing to its broad health effects.
Why it matters
This is one of the more replicated exposures in human epigenetic research. It provides a mechanistic underpinning for what we already knew: movement matters.
The Science
Studies show exercise alters methylation patterns in genes related to metabolism, inflammation, and mitochondrial function. Effects are dose-dependent and tissue-specific.
The NSI Perspective
NSI treats movement as one of the most reliable inputs to healthy gene regulation.
Clinical Implications
Prescriptive movement remains one of the best-evidenced interventions across chronic disease.
Practical Application
You do not need to run marathons. Consistent movement reaches your genes.
