Understanding the signs of panic and agoraphobia, such as racing heartbeat, lightheadedness, and tense muscles, as well as the variables that can cause panic, such as crowds, wide open spaces, and enclosed locations, can be helpful. Further research revealed that biological factors, thinking patterns, life events, and evolutionary factors all contribute to the development of panic. Finally, techniques for overcoming panic include learning more about anxiety and panic, developing breathing techniques, confronting anxieties, and challenging harmful thinking.
