Claustrophobia is an anxiety disorder characterized by an intense fear of enclosed or confined spaces. People with this condition may experience panic attacks when in situations like elevators, small rooms, or crowded areas. Symptoms can include rapid heartbeat, sweating, and a feeling of being trapped. This fear can significantly impact daily life, making it difficult for individuals to engage in activities that involve tight spaces. Treatment options often include therapy, such as cognitive-behavioral therapy, and relaxation techniques to help manage anxiety. In some cases, medication may also be prescribed to alleviate symptoms.
