Acrophobia

Acrophobia (from the Greek: ἄκρον, ákron , meaning “peak, summit, edge” and φόβος, phóbos, “fear”) is an extreme or irrational fear of heights. It belongs to a category of specific phobias, called space and motion discomfort that share both similar etiology and options for treatment.

Most people experience a degree of natural fear when exposed to heights, especially if there is little or no protection. Those who are confident in such situations may be said to have a head for heights.

Acrophobia sufferers can experience a panic attack in a high place and become too agitated to get themselves down safely Between 2 and 5 percent of the general population suffer from acrophobia, with twice as many women affected as men.

Vertigo” is often used (incorrectly) to describe a fear of heights, but it is more accurately a spinning sensation that occurs when one is not actually spinning. It can be triggered by looking down from a high place, or by looking straight up at a high place or tall object, but this alone does not describe vertigo. True vertigo can be triggered by almost any type of movement (e.g. standing up, sitting down, walking) or change in visual perspective (e.g. squatting down, walking up or down stairs, looking out of the window of a moving car or train). Vertigo is qualified as height vertigo when referring to dizziness triggered by heights
