Height phobia or acrophobia is an irrational fear of heights, especially when one is not really that high up. The symptoms include feeling terrified, shaking, sweating, having heart palpitations, crying, and panic attacks. Some people with this condition may become so agitated that it is difficult for them to get back down safely. Height phobia may be caused by a previous fall or having seen someone experience a disastrous fall. Hence, someone with this specific fear finds it stressful to use a glass elevator or cringe at the idea of having to attend a meeting on the 10th floor. Treatments include virtual reality therapy, anti-anxiety medications, and desensitization techniques.
