Neurobiology of Safety

The neurobiology of safety refers to how our brain processes signals that indicate a safe environment, triggering feelings of security and calmness. When we perceive safety—such as trusted relationships or familiar surroundings—our brain's threat detection systems deactivate, allowing calming regions to activate. This reduces stress hormones, encouraging relaxation and connection. Conversely, feeling unsafe activates stress responses, which can impair thinking and emotional regulation. Understanding this helps us recognize how safety cues promote well-being by engaging neural circuits that foster trust, resilience, and emotional stability.
