What are the symptoms of carsickness
1. The body is out of balance.
The human body can judge the direction and maintain its own balance, which is mainly in the joint responsibility of shallow skin receptors, eyes, neck, deep body receptors and inner ear, among which the inner ear is the most important. The semicircular canals of the inner ear, as well as the saccules and saccules, have the function of balance. There are three semicircular canals, which are perpendicular to each other and form three sides of the space. They receive the external balance stimulation, through the vestibular nerve, to the balance center of the cerebral cortex, to regulate and manage the balance response.
2. A person is stimulated.
Motion sickness is called motion sickness or motion sickness in medicine. Motion sickness is a general term for motion sickness, seasickness and airsickness. It has a direct relationship with the vestibular balance of our inner ear. Specifically speaking, sports disease is not a real disease. Different from the common disease, it is only the emergency response of the sensitive organism to the over limit stimulation. Dizziness and even vomiting while driving. In life, some people often feel dizzy, sick in the upper abdomen, sweating or even vomiting soon after they get on the car. Especially when the car is braked, swerved or started suddenly, it is more severe. After getting off the car for a rest, it can gradually reduce or recover. Some people suffer from carsickness for several days.

4. Induce other symptoms.
Inflammation or trauma can also induce this disease, for example, in the process of viral labyrinthitis or chronic suppurative otitis media, white blood cells, phagocytes or endothelial debris enter the inner lymph; in brain injury or stapes surgery, blood enters the inner lymph, can form tangible particles, and sink on the top of ampullary crest. Barber reported that 47% of the patients with longitudinal temporal bone fractures had positional vertigo, and 20% of the patients without fracture had this sign. In 100 cases of otitis media, 26% of them had positional vertigo. Ear surgery, such as tympanoplasty, mastoidectomy and so on, can also cause vestibular injury.
5. There are other complications.
The oval sac, the superior semicircular canal and the outer semicircular canal distributed in the anterior vestibular artery and the superior vestibular nerve branch were denatured, while the saccule and the posterior semicircular canal were normal. Therefore, hypertension, heart disease and vertebrobasilar artery insufficiency could cause the embolism of the anterior vestibular artery, resulting in the degeneration and falling off of the otolith membrane, which was deposited on the ampullary ridge.
Treatment of carsickness
The simplest, effective and practical way is to put on headphones and listen to music, and turn up the volume a little, so as to interfere with the response of the inner ear to balanced stimulation. If you know that you will get carsick when driving, you can also take preventive measures first.
It's also very good to solve these problems with natural methods. When there's no medicine, people who are carsick can tighten their belts before getting on the train to prevent the internal organs from shaking too much in the body. After getting on the train, they can look at the distance with their eyes, and try to look at the near objects as little as possible. Especially when going downhill, they should pay attention to grasping their hands, slow down the impact of inertia on the internal organs, and pay attention to ventilation when sealing the car or the car with strong smell of gasoline It helps to prevent carsickness. If you feel a little uncomfortable, you should immediately choose the right seat in front of the car to sleep, which is often the best and most cost-effective way to prevent carsickness.
