Struggling to breathe, or Fear, triggers the brain’s fight-or-flight response. Increased heart rate pumps blood to organs quicker, preparing muscles for action. It also induces faster breathing to oxygenate the muscles. Breathlessness may ensue.
Another way to look at it is that your anxiousness will make you feel even more out of breath. People often overbreathe or hyperventilate during a panic episode. If you begin to breathe too fast in reaction to a panic episode, you may inhale more oxygen than your body requires.
Is shortness of breath due to worry or cardiac problems? Insufficiency of breath after coping with stress is most often the result of worry. Feeling lightheaded or faint, a racing heart, hyperventilation (rapid breathing), chest pains, headaches, trembling or shaking, sweating, and nausea or stomach aches are all possible physical symptoms. Regular exercise, breathwork, nutrition may help reduce anxiety and stress by releasing feel-good endorphins, endogenous cannabinoids, and other natural brain chemicals.
