Adaptive stress response
The principle behind exercise, fasting, heat and cold alike: the stressor is not the benefit, the adaptive response is. And here more is reliably worse - a hormetic dose strengthens, the same input at higher dose damages. There is no version of this where doubling the stimulus doubles the benefit.
In depth
Adaptive strengthening in response to a mild stressor — exercise, fasting, heat, cold and plant xenobiotics all work this way.
What drives it
Training load increases it.
Exercise is the archetypal hormetic stressor - the adaptation, not the session, is the benefit. Carried by the hormesis, inflammaging and thermogenesis reviews. doi 10.1002/med.21743
Fasting response increases it.
Caloric restriction and time-restricted feeding act through the same adaptive-response logic. Carried by the hormesis, inflammaging and thermogenesis reviews. doi 10.1002/med.21743
Heat shock response increases it.
Heat-shock protein induction is the molecular signature of a hormetic heat stimulus. Carried by the hormesis, inflammaging and thermogenesis reviews. doi 10.1002/med.21743
What The Cold Turns On increases it.
Cold-shock protein induction is the cold-side equivalent. Carried by the hormesis, inflammaging and thermogenesis reviews. doi 10.1002/med.21743
What it drives
It increases Antioxidant defense.
NRF2 induction by plant xenobiotics is xenohormesis - a mild chemical stress producing an antioxidant response. Carried by the hormesis, inflammaging and thermogenesis reviews. doi 10.1002/med.21743
It increases Energy sensing.
Energy stress activates AMPK, which is the metabolic arm of the hormetic response. Carried by the hormesis, inflammaging and thermogenesis reviews. doi 10.1002/med.21743
It increases Cellular cleanup.
Autophagy induction is one of the principal adaptive outputs. Carried by the hormesis, inflammaging and thermogenesis reviews. doi 10.1002/med.21743
It reduces Cellular aging.
The adaptive responses hormesis triggers are the ones that oppose the hallmarks. Carried by the hormesis, inflammaging and thermogenesis reviews. doi 10.1002/med.21743
It increases Stress resilience.
Resilience is the trained capacity that repeated hormetic exposure produces. Carried by the hormesis, inflammaging and thermogenesis reviews. doi 10.1002/med.21743
