Definition
Stress exposure across life influences gene expression in documented ways — particularly of genes involved in the HPA axis, inflammation, and immune function.
Why it matters
Framing stress as a biological input to gene expression removes moralization and clarifies why chronic stress matters at a cellular level.
The Science
Chronic stress is associated with epigenetic changes at glucocorticoid receptor sites and inflammatory pathways. The specifics vary; the pattern is robust.
The NSI Perspective
NSI treats chronic stress as one of the primary biological loads on the modern nervous system.
Clinical Implications
Reducing chronic stress load is not luxury care.
Practical Application
Sustained stress reaches genes. Not in mystical ways — in measurable ways. Reducing it is real medicine.
