Training your brain to stop fear responses takes consistency and patience. Exposure therapy is one way, gradually and repeatedly exposing yourself to the fear in a controlled way, like dipping a toe in the pool before diving in. Cognitive-behavioral therapy (CBT) can also retrain your brain by challenging and changing unhelpful thoughts and behaviors, rewiring your reactions to fear over time. Mindfulness-Based Stress Reduction (MBSR), Biofeedback, and EMDR may be further options for exploring your stress response in thoughtful ways with a trained practitioner.
