Roller coaster phobia is a colloquial and slang term describing an individual's fear of roller coasters. While roller coasters are the most popular theme park attraction, certain people feel nauseated, afraid, dizzy, or unsafe when riding roller coasters. In the majority of cases, this fear is related to acrophobia, claustrophobia, or a traumatic event. Roller coaster phobia can be overcome relatively easily, the best cure being going on the tallest/fastest roller coaster before riding roller coasters of a lesser magnitude. Roller coaster phobia has been linked to previously experiencing an accident, vertigo, and fear of heights. In rare cases, riders may be afraid of roller coasters due to a painful ride, tight restraints, being thrown around in the restraints, and excessive g-forces on the body of the rider. ==Acrophobia== ''See also'' Acrophobia The name of this phobia comes from the Greek word ''acro'' meaning "great height." Much of those suffering from acrophobia fear falling more than the actual height.〔 Studies on acrophobics have found that they may be unable to climb to the upper floors of buildings or even climb up ladders.〔 Some acrophobics are perfectly fine when viewing tall structures from the ground, but are unable to keep their composure when at the top of that height. They might cling to the guardrail and avoid being anywhere near the edge of the structure. They tend to be overwhelmed by their fear and are unable to overcome it. A study in 2005 on the causes of acrophobia found that this phobia might also be related to acute case of height vertigo, which is caused by the inability to maintain balance without adequate visual feedback. When a critical distance between an individual and the closest visible stationary object is exceeded, symptoms of dizziness are triggered. The excessive distance between a person and the ground induces an absence of sufficient visual information used to retain balance.〔 Because most roller coasters combine substantial heights with seemingly insignificant support, as well as free-falls and the illusion of uncontrolled drops, someone who is an acrophobic would have an extremely negative reaction to riding roller coasters. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Roller coaster phobia」の詳細全文を読む スポンサード リンク
