The term for the phobia that involves fear of heights is acrophobia. Individuals suffering from acrophobia experience intense anxiety, panic attacks, and discomfort when in high places or even when thinking about heights. This phobia can be triggered by a variety of situations, such as climbing stairs, standing on bridges, or looking out from tall buildings. Symptoms may include dizziness, sweating, heart palpitations, and a strong desire to escape the situation. Treatment options vary and can include therapy, medication, and gradual exposure to heights to help manage anxiety.
