Claustrophobia is a type of specific phobia, which is an anxiety disorder that is characterised by a persistent and excessive fear of a specific situation. In the case of claustrophobia, the feared situation is a confined or enclosed space.
People with claustrophobia may experience a range of physical and emotional symptoms when they encounter a confined or enclosed space, such as:

• Sweating
• Trembling
• Rapid heartbeat
• Shortness of breath
• Nausea
• Dizziness
• Feeling faint
• Panic attacks
• Fear of being trapped
• Fear of suffocating
• Fear of losing control

Claustrophobia can have a significant impact on a person's life. It can prevent people from using public transportation, going to the movies, or even being in a crowded room. It can also lead to social isolation and depression.
