Motion sickness is not induced by 4DX. Your tolerance for seat swiveling and other criteria, such as your health, will, nonetheless, be a determining factor. The movement of the seat should not frighten you if you are not easily startled. You must be at least four years old and three and a half feet tall to enter a 4DX theater, for example, according to safety regulations. One is recommended not to take 4DX if one is pregnant, has epilepsy, heart disease, or is elderly.
