7 Shortness of Breath
Anxiety related breathing issues tend to be a result of hyperventilation. Hyperventilation also known as over breathing occurs when your body is receiving too much oxygen and is expelling too much carbon dioxide.
Becoming conscious of how you are breathing, and having a hard time catching your breath is a common symptom of anxiety. Feeling like you have to force yourself to breathe in fear that if you don't, you might pass out, or for no apparent reason you feel out of breath and find youself doing an unusual amount of yawning in an attempt to catch your breath. It can also feel like you're so out of breath that you have to gasp for air, or that you can't breathe deep enough.
Shortness of breath, when it's related to anxiety will go away once your breathing returns to normal. If you can control compensating by trying to get too much air, you should be able to get your breathing to feel natural again.
Taking a relaxing walk or doing some breathing exercises will help regulate your air intake.
