The fear of heights is called acrophobia. It is a type of specific phobia that involves an intense fear of heights, marked by panic and anxiety. People with acrophobia experience intense fear and anxiety when they think of tall heights or are positioned at a significant height. They often avoid situations or places that involve heights. While a certain amount of concern around heights is normal for all people, acrophobia is excessive to the situation, persistent, and can cause a person to avoid situations where they might be exposed to heights.
