What Causes Motion Sickness?

[SanBennett]

Motion sickness is a type of kinetosis, which is further classified into car sickness, sea sickness, air sickness (aero sickness), and space sickness depending on the mode of transportation. Kinetosis is a condition caused by any form of accelerated motion—such as bumps, sways, or rotations—generated by cars, ships, or airplanes, which stimulates the human vestibular nerve. 1. Introduction: The vestibular apparatus in the inner ear is the body's balance-sensing organ, consisting of three semicircular canals and the utricle and saccule in the vestibule. It can detect stimuli from various specific motion states. 2. Additional Information: Compared to adults, children are more prone to motion sickness and experience more severe symptoms. This is because the vestibular function is not fully developed before the age of 4, gradually maturing after 4 years and reaching full development by age 16. As the vestibular function progressively improves, a child's motion sickness symptoms will lessen and eventually disappear.
