Introduction
Hormesis is the idea that manageable stress can support adaptation, but more stress is not automatically better.
Research Summary
The evidence across cold, heat, and contrast therapy supports a practical theme: protocols matter, and adaptation depends on context.
What This Means for Consumers
Choose recovery tools that make consistent, controlled exposure easier rather than chasing maximum intensity.
