Causes of dizziness by car
1. Carsickness is related to vestibular balance receptors in the inner ear
The interesting phenomenon is that people who are carsick can drive but can't take a car, because motion sickness is mainly caused by the stimulation of the vestibular nervous system, so the excitability of the vestibular nervous system is the key. Vestibular nervous system belongs to the low-level center, which is affected by the high-level center of cerebral cortex, and the high-level center has inhibitory effect on the low-level center. When a carsick person drives, his mind is in a state of high concentration, and the high-level center of cerebral cortex is highly excited, which has an inhibitory effect on the vestibular system. Naturally, he will not get carsick. However, there is no such effect in the case of passengers. Similarly, when the battle alarm goes off, the Navy officers who were seasick can immediately fight with high morale.
2. Why do some people get carsick originally but get vertigo disease hind not carsick however
Good vestibular function of inner ear is one of the basic conditions for motion sickness. If the vestibular function is lost, the human body will lose the ability to receive various acceleration (deceleration) motion stimuli, that is, all kinds of adverse or overrun stimuli that cause motion sickness will lose their effect on the human body. Therefore, after the original carsickness patients get vertigo, some of them with bilateral vestibular function loss (ototoxic drug poisoning, bilateral labyrinthine resection, repeated vertigo attacks, etc.) will not be carsick.
3. The more advanced the vehicle the carsick person takes, the more likely he is to get carsick
Although the vestibular function of the inner ear is good, and it is one of the basic conditions to produce motion sickness (seasickness, carsickness, airsickness), there is a certain range of acceleration (deceleration) motion stimuli suitable for producing motion sickness. Those high-frequency bumps (produced by ordinary vehicles) are not suitable for it, but those with better stability are produced in operation Surging acceleration is the most suitable for vestibular taste. So the more advanced the vehicle is, the easier it is to get carsick.
4. The smell of gasoline can cause carsickness
Carsickness is caused by the stimulation of the vestibule of the inner ear. The smell of gasoline may aggravate the nausea symptoms of some carsick people, but it is not the cause of carsickness. Just imagine, will you get carsick when you smell gasoline at home? As for some people who are allergic to gasoline, it's another matter.
