Why is Carsickness worse when looking at the phone?
Carsickness is actually not the car, but motion sickness. Motion sickness is also called “motion sickness” in medicine.
Eyes and ears are the main organs for the human body to feel the state of movement.
The eyes can directly perceive whether we are moving through the optic nerve and by observing changes in the environment.
In the ear, there is a sophisticated balance perception system-the vestibule, which can feel whether we are really moving, whether we are moving uphill or downhill, accelerating or decelerating, moving horizontally or vertically.
Purple part: cochlea and vestibular system
Under normal circumstances, the information provided by the eyes and ears (vestibular system) should be consistent.
But when sitting in a swaying car, the movement of the eyes and the car is relatively static, and the picture you seen is relatively stable; while the ears are strongly stimulated during the bumps and changes of direction. This makes the information they receive divergent-
Ears: you moved
Eyes: you didn’t move
At this time, the brain receives two inconsistent reports, which makes it a little dizzy: No…Is it moving?
Looking at the mobile phone will focus the line of sight on the static part, making the brain’s judgment more confusing, so when looking at the mobile phone, it will often become more dizzy.
But just faint, why want to vomit?
At present, there is a speculation that after the brain was dizzy, thought it was poisoning and had hallucinations, so it had to spit out to save life…
In addition, some people find that they no longer get carsickness after getting older. This may be because the nervous system has matured, or it may be because the ears become dizzy and get used to it, and the reaction is reduced.
If you have a motion sickness physique, it is best to avoid playing with your mobile phone, look out the window more, or sleep in the car. If it’s really serious, just ask for motion sickness medicine.
