The Hormesis Principle
What doesn't kill you makes you stronger
Hormesis is the biological principle that small, controlled stressors trigger adaptive responses that make you more resilient. Cold, heat, fasting, and exercise all work through hormesis.
Match the stressor to the adaptation
Connect each hormetic stress to the body's response.

The dose makes the poison
Too little stress = no adaptation. Too much = injury. The sweet spot is brief, intense, and followed by adequate recovery. This is why protocol design matters.

Key Takeaway
Hormesis is the unifying principle behind most longevity biohacks. The key is controlled dose + adequate recovery.
