Motion sickness is usually common in children and gets better as they get older. However, some people are affected by genetic factors as well as vestibular development, which makes it difficult to cure, so people with motion sickness may be seasick for the rest of their lives. Motion sickness is the clinical manifestation of dizziness, nausea and vomiting caused by the body’s inability to adapt to the displacement and movement of the body when the car starts, walks and stops during the car ride. Motion sickness is caused by the poor vestibular function of the organism, which cannot adapt to the displacement change, and is a manifestation of congenital vestibular dysfunction. For motion sickness, patients can only try to avoid it. If the patient’s motion sickness is very obvious during or after a car ride, he or she can take oral teabufagine or diphenhydramine to relieve the motion sickness symptoms, but the motion sickness symptoms will come back when he or she rides again. Patients with motion sickness can usually perform vestibular function exercises under the guidance of a doctor, and when vestibular function is improved, motion sickness will be reduced. In addition, when riding in a car, it is recommended to choose a position near the window, where the air circulation is better and may reduce the symptoms of motion sickness.
