A man with low body resistance can become ill by it during a trip. Manifestation of kinetosis increases from emotional stress, which, in same queue, grows during movement in the car. Because of constantly changing position of man in space from vestibular receptors, being in an internal ear, irritating impulses enter cerebellum by continuous stream, from where passed in the different centers of the parasympathetic nervous system. At the strong irritations of vestibular apparatus dizziness appears, co-ordination of motions is violated, there are squeezes, cramps in a stomach, head pain, nausea, vomiting, fear.

A vestibular apparatus has the sensible hair cages of internal ear, endolymph, otoliths that are plugged in it and cupula ampoules of the semicircular canals. The natural irritants of vestibular apparatus are inertia changes of endolymph, arising up in the semicircular canals.

Presently there are sufficiently many good preparations of rapid and long action, for example, antihistaminic, which reduce distribution of impulses from a vestibular apparatus in the parasympathetic nervous system to the minimum.
