Hormesis: why a little stress makes the body stronger
12 min
Exercise, heat, cold, and fasting are all forms of stress that strengthen the body in small doses and harm it in large ones. Explore the dose-response science of hormesis and what it really says about the popular idea of 'what doesn't kill you.'

Low-dose stressors trigger adaptive homeostasis, causing the body to overcompensate and build resilience buffers.
The Nrf2 protein regulates over two hundred genes responsible for detoxification and cellular repair.
Brief periods of low oxygen or mild chill can precondition organs against future severe events.
Sauna use mimics exercise by subjecting the body to transient hyperthermia and heat shock proteins.
Intermittent fasting triggers autophagy, a process where the body recycles its own damaged cellular components.
Xenohormesis suggests humans gain health benefits from the stress signals produced by plants like grapes.
