Claustrophobia

Name(s): 
Fear of confined spaces
Nature

Claustrophobia is the fear of confined spaces. It can be triggered by many situations or stimuli, including elevators, especially when crowded to capacity, windowless rooms, and hotel rooms with closed doors and sealed windows. Even bedrooms with a lock on the outside, small cars, and tight-necked clothing can induce a response in those with claustrophobia. It is typically classified as an anxiety disorder, which often results in panic attacks. The onset of claustrophobia has been attributed to many factors, including a reduction in the size of the amygdala and classical conditioning.

One study indicates that anywhere from 5-10% of the world population is affected by severe claustrophobia, but only a small percentage of these people receive some kind of treatment for the disorder.

The term claustrophobia comes from Latin claustrum "a shut in place" and Greek φόβος, phóbos, "fear".
