Although many people breathe into a paper bag in an attempt to alleviate the hyperventilation that can be associated with panic, the benefit received may be the result of the individual thinking it will help (a placebo effect). Unfortunately, breathing into a paper bag while having trouble breathing can worsen symptoms when the hyperventilation is caused by a condition associated with oxygen deprivation, like an asthma attack or a heart attack.
Learn how to control your breathing. Hyperventilation brings on many sensations (such as lightheadedness and tightness of the chest) that occur during a panic attack. Deep breathing, on the other hand, can relieve the symptoms of panic. By learning to control your breathing, you can calm yourself down when you begin to feel anxious. And if you know how to control your breathing, you’re also less likely to create the very sensations that you’re afraid of.
People with panic disorder often worry about when the next attack will happen and actively try to prevent future attacks by avoiding places, situations, or behaviors they associate with panic attacks. Worry about panic attacks, and the effort spent trying to avoid attacks, cause significant problems in various areas of the person’s life, including the development of agoraphobia (see below).
