Can Anxiety Cause Shortness of Breath?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
Yes, anxiety can absolutely cause shortness of breath through several physiological mechanisms. When you experience anxiety, your body activates the fight-or-flight response, releasing stress hormones like adrenaline that increase heart rate and breathing patterns. This can lead to hyperventilation, where rapid breathing reduces carbon dioxide levels in your blood, creating a sensation of breathlessness. Studies show that up to 75% of people with anxiety disorders experience breathing difficulties as a primary symptom. The chest tightness and air hunger feeling can create a cycle where breathing problems worsen anxiety, which further affects breathing patterns.
