The problem with catastrophizing is that it is rigid thinking. Suppose you worry that you’re having a heart attack every time you experience some chest pain. It’s usually easy for a health professional to distinguish between anxiety and a heart attack. But catastrophizing resists new information. Even though, your doctor has done tests in the past and has reassured you many times, you worry that this time will be different. Your exaggerated fear is preventing you from changing your thinking, and is keeping you stuck.
When people are confronted with unpleasant and potentially harmful stimuli such as foul odors or tastes, PET-scans show increased bloodflow in the amygdala.[87][88] In these studies, the participants also reported moderate anxiety. This might indicate that anxiety is a protective mechanism designed to prevent the organism from engaging in potentially harmful behaviors.
Another important prevention strategy for anxiety is to incorporate exercise into your daily activities. Exercise has been shown to decrease stress hormones that influence anxiety and also improve overall mood. Exercise can also help you disengage from worry and stress and focus on the current task of exercising. Exercises such as light jogging or brisk walking that can be incorporated into your daily activities can help reduce the impact of anxiety when it occurs.
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).
