The physical toll of poor boundaries: How saying "yes" strains your nervous system.

We often treat boundaries as an abstract emotional or relational exercise. But to your physiology, an crossed boundary is a direct physical event.Every time you say "yes" when your nervous system is screaming "no" (whether to taking on extra workload, tolerating disrespectful behaviour, or overcommitting your time) your brain interprets the overextension as a threat to your personal resources. Over time, failing to assert clear limits keeps your body locked in a state of low-grade, persistent sympathetic arousal.
