Why does anxiety cause physical symptoms?

Anxiety triggers the fight-or-flight response, releasing stress hormones. This increases heart rate, muscle tension, breathing changes, and other physical responses.

Are anxiety-related physical symptoms dangerous?

Physical symptoms are uncomfortable but not dangerous. However, they can mimic serious conditions, so medical evaluation is sometimes needed for reassurance.

How can grounding techniques help physical anxiety symptoms?

Grounding techniques redirect attention from physical sensations and calm the nervous system through techniques like 5-4-3-2-1 sensory awareness.
