Why is it that some people get motion sickness while riding in a car, while the majority do not? In fact, this is related to individual physical fitness, and some people believe that there are certain factors related to genetics. Some children may also experience motion sickness, is this also hereditary? Next, let's learn about the causes of motion sickness in children?
1. Constitution: Some people are born with a lower threshold for activating their balance system, so when there is a slight mismatch between visual and vestibular senses, they are easily stimulated and experience dizziness. Of course, this also needs to consider whether there are other influencing factors in the objective environment.
2. Physical condition: When taking transportation, if you happen to have an upper respiratory tract infection, there is often a chance for the virus infection to invade the inner ear or vestibular balance system, which may make you more prone to motion sickness than usual. Prior to this, if one ate too much or consumed difficult to digest foods such as carbonated drinks, milk, etc., causing bloating, then any slight stimulation of the parasympathetic nervous system would lead to gastric acid secretion, making it more likely to cause vomiting. In addition, factors such as insufficient sleep, anxiety stimulation, neuroticism, poor gastrointestinal condition, and headaches are all influencing factors.
3. Genetics: If parents or family history have severe cases of motion sickness, the proportion of children developing motion sickness is relatively high.
4. Self suggestion: Children who frequently experience motion sickness are also more likely to fall into self suggestion and relapse.
5. Smoothness of travel: The road surface is bumpy, causing the car to shake violently, and so on. The smoothness of ships and planes also needs to be considered.
6. Odor: There is a special odor or gasoline smell in the air.
7. Seat: Due to the seat, or constantly looking at moving scenery outside the window or reading a book, the visual and vestibular inputs to the brain are inconsistent.
