The fear of tight spaces is called claustrophobia. This specific phobia is characterized by an intense fear or anxiety associated with being in confined or crowded spaces, such as elevators, small rooms, or crowded areas. Individuals with claustrophobia often experience symptoms like panic attacks, shortness of breath, rapid heartbeat, and an overwhelming urge to escape the situation. The fear can stem from various causes, including past traumatic experiences or feelings of loss of control. Treatment options available include therapy, particularly cognitive-behavioral therapy, and exposure therapy, which helps individuals gradually confront and manage their fear in controlled environments.
