Hormesis
back to main page
Hormesis is a biological adaptive phenomenon in which the organism reacts favorably to the action of a small, controlled stressor. A stimulus that could be harmful at high intensity activates repair, regenerative, and protective mechanisms in a small dose. This phenomenon is observed both at the cellular level and in the entire organism. Hormesis currently represents one of the key models explaining the impact of lifestyle on longevity, metabolic resilience, and regenerative processes. Modern longevity medicine utilizes hormetic mechanisms in anti-aging, regenerative, metabolic, and neurological therapies, relying on controlled exposure of the organism to stimuli such as physical exertion, cold, heat, intermittent fasting, or mitochondrial stimulation.
