Virtual reality headsets are usually associated with video games and fun. However, companies are also looking at using them for mental health therapies, to treat phobias, anxiety or addictions.
Some phobias can be treated by exposing a patient to his or her worst fear over a period of time. This could be a fear of spiders, plane travel or small, enclosed spaces. Virtual reality helps to create audiovisual therapies in a safe environment.
So if someone is scared of public speaking, he would be put in a room that is full of people, virtually. Exposure therapies help people enter a situation they fear through imagined exercises.
