Abstract

Calabrese and Baldwin argue hormesislow-dose stressors can strengthen biological systems while high doses harm — challenging linear dose-response dogma.

Key findings

  • Biphasic curveLow dose helps, high dose hurts — U-shaped response.
  • Adaptive stress — Small challenges prime repair — antifragile logic.
  • Dose-response revolution — Toxicology and medicine revisit linear models.
  • Context bound — What is low dose depends on system — not universal tonic.

Limits

Synthesis review — strong map for the field, not one fresh trial; use for orientation before primary studies.
