Phobia and fears are related but different in their normality of the fear. Fear is an emotion that we feel naturally to protect us from harm when we are faced with real and imminent danger. An excessive level of fear or anxiety that is out of proportion with the actual level of danger that an object or situation presents is called a phobia. Phobias are abnormal reactions of fear or anxiety that can cause avoidance behavior when the individual is exposed to the object or situation at the center of their phobia. Fears are a natural part of our human nature and are shared across all species as a means to protect themselves from danger to life and limb. It allows us to anticipate danger to be able to react to it accordingly and ultimately protect ourselves from harm. Phobias on the other hand are anxiety disorder that is excessive and not in line with the actual danger, if there is any, of the object at the center of the phobia.
