The amygdala evaluates sensory information for emotional processing, especially potential threats, and triggers appropriate responses (e.g., fight-or-flight).

It is most famous for its role in generating and regulating fear and anxiety.

The amygdala is also implicated in aggressive and defensive behaviors.

Chronic stress can cause the amygdala to become overactive, which may:

• Heighten emotional reactivity and anxiety
• Impair rational decision-making by weakening the prefrontal cortex
• Contribute to mental health issues such as depression, PTSD, and anxiety disorders

• Practices like meditation, walking, and grounding techniques can help reduce amygdala activity and lower stress/anxiety levels.
• Exposure to feared situations can help retrain the amygdala and reduce fear responses. Nothing diminishes anxiety faster than action.
• Emotional regulation strategies and reframing fear as information are effective for managing amygdala-driven responses.
