Definition
Sleep, and sleep disruption, produce documented epigenetic and gene-expression changes across immune, metabolic, and stress-related pathways.
Why it matters
This adds a mechanistic layer to what sleep science already established (Collection 11): sleep is not incidental.
The Science
Sleep restriction alters expression of inflammatory and circadian genes; shift work is associated with altered methylation patterns; chronic insomnia shows gene-expression signatures.
The NSI Perspective
NSI treats sleep as reaching every biological level — including gene regulation.
Clinical Implications
Sleep intervention has effects at cellular scale, not only behavioral scale.
Practical Application
A protected sleep schedule reaches into your genes. That is neither exaggeration nor marketing.
