The term for the fear of small spaces is *claustrophobia.* Individuals suffering from this anxiety may experience intense fear or panic when confined in a small area, such as an elevator, crowded room, or enclosed environment. Claustrophobia can lead to avoidance behaviors, where people deliberately steer clear of situations that may trigger their fear. It is classified as a specific phobia, which can manifest in various degrees, impacting daily life and activities. Treatment options include therapy methods like cognitive-behavioral therapy (CBT) and exposure therapy, enabling individuals to manage their anxiety and improve their quality of life.
