The alarm response
A possible threat can activate protective systems, leading to a faster heartbeat, sweating, trembling, changed breathing, dizziness, stomach discomfort and muscle tension. These sensations are real.
The symptom cycle
Interpreting a body sensation as danger may increase fear, which can intensify the sensation. Naming it and gently returning attention to present sensory information may help.
When to seek help
Seek professional assessment if symptoms recur or interfere with life. New or severe chest pain, fainting or serious breathing difficulty requires medical evaluation rather than being assumed to be anxiety.
