Exposure therapy is a form of treatment used to help people cope with their fears and anxiety. It works by gradually exposing a person to the thing they fear or are anxious about until they become used to it, and their fear goes away. For example, someone with a fear of heights might start by looking at pictures of tall buildings or mountains, then slowly move up to going for a walk at a viewpoint, and eventually taking a ride in an elevator or going bungee jumping. The goal is to help them learn to cope with their fear without being overwhelmed by it.
