Stress habituation in self-defense

Stress habituation is the main self-defense training lever. Exposing the nervous system to graded stressors (mild then intense) raises the freeze threshold — you function at stress levels that would freeze an untrained person.

なぜ起こるのか — メカニズム

Principle: the nervous system learns 'stress normality' via repeated exposure. Meichenbaum (1985) on stress inoculation: 6 sessions double the freeze threshold. Limit: if recovery capacity is exceeded, you traumatize instead of habituating.

Yehouda doses precisely: start at 30% intensity, climb 10% per session. Never above 80% for advanced students. Exposure safety matters as much as intensity.
