Acrophobia
Acrophobia, a fear of heights, is also known as Altophobia.  It comes from the Greek word “Akron” meaning summit.  People with this phobia might get panic attacks when they are in high places. The panic attack may include trembling, shortness of breath, sweating, nausea, heart palpitations, dizziness, choking sensations, hyperventilation, or parenthesis (Tingling sensations).  They also might become too agitated to get down from where they are, causing them to fling themselves over the edge while not trying to be suicidal.  Vertigo, a head rush, often associated with Acrophobia is incorrect.  The correct association would be a spinning sensation when in high places.  Acrophobia affects different people in different levels.  Some might have a panic attack while others might just get dizzy or cry.  So it is safest to keep people with this fear out of planes, trees, upstairs windows, and any other high places.
