Motion sickness is not an organic disease, but a psychological illness that belongs to one of the phobias.

Fear is one of the most primitive human emotions, and unlike anxiety, fear is an adaptive response to a real threat.

Anything that can pose a danger or threat to a person can trigger fear. People may develop phobia neurosis when they develop a sense of fear that is not in harmony with the actual danger in situations or situations that should not normally cause fear. There are three main types of phobias: place fear, social fear, and peculiar fear.

Sickness is a specific phobia. People with paraphobia are irrationally afraid of a specific situation or thing, and once exposed to the situation or confronted it, they will develop a severe sense of depression and fear. For example, fear of heights, hydrophobia, animal fear, etc., even if there is no threat, fear can occur.

Specific fears include fear of vomiting, fear of suffocation, and even fear of HIV infection. It usually begins at an early age, is more common in women, and rarely has other symptoms or syndromes. This disorder is the same phobia as the "object terror" of fear of seeing snakes and caterpillars, and the "communicative terror" of fear of seeing strangers and the opposite sex, and is not necessarily related to timidity.

Motion sickness is also different from motion sickness, the former is similar to fear of heights and is a psychological problem; The latter is a physiological problem of the balance organ of the inner ear. Although the cause of motion sickness has not yet been clarified, this mental disorder is certainly not the type of psychosis commonly known as "neuropathy". Except that they can't see blood, people who faint blood are no different from ordinary people.
