There are many ways that acrophobia can be treated. No set way works for everyone. Hypnotism is one very effective solution for some people with the problem. Therapy is another treatment that sometimes works too. Then there is conditioning therapy where the person who has acrophobia actually goes through with his or her worst fears.
They are placed in a situation where their acrophobia acts up and they have to work through it successfully. Sometimes, it takes more than one time. There are more treatment options besides - some work for some people and some people struggle to find any relief.
