A phobia is an overwhelming and unreasonable fear of an object or situation that poses little real danger but provokes anxiety and avoidance. Unlike the brief anxiety most people feel when they give a speech or take a test, a phobia is long lasting, causes intense physical and psychological reactions, and can affect your ability to function normally at work or in social settings.
Several types of phobias exist. Some people fear large, open spaces. Others are unable to tolerate certain social situations. And still others have a specific phobia, such as a fear of snakes, elevators or flying.
Not all phobias need treatment. But if a phobia affects your daily life, several therapies are available that can help you overcome your fears — often permanently.
