What is the fear of people who often go out to play? It's just that they don't enjoy themselves. How can I not have a good time? I am carsick and seasick. Why does this happen?
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.
Why do you get carsick?
1. Individual differences. When the incoming balance stimulus is too strong, such as sudden braking and sharp rotation, even in the safe and normal state of the balance system, people will feel dizzy. This is a normal physiological phenomenon, which can disappear in a moment. But some people have poor tolerance and strong response to slight balanced stimulation.
2. Poor sleep and overwork are easy to occur.
3. It is easy to happen when you are hungry or full.
4. Some ear diseases may occur.
5. The car is closed so that the air is not circulating, or the smell of some substances is irritating, such as gasoline, etc.
How to prevent carsickness?
1. People who are often carsick can take chengxining before taking the bus. Adults can take 25 mg each time. Children can take less to prevent carsick reaction.
2. You can't eat enough or starve before driving.
3. Don't overwork before driving. Sleep well the night before.
4. You can sit in the front of the car to reduce the bumps, open the windows to make good ventilation, and lean your head back on the fixed position later, close your eyes, so as to reduce the head vibration and the dizziness caused by the flying of your eyes.
5. Take domperidone or metoclopramide when vomiting. Take sedatives when you are nervous, such as diazepam.
6. At ordinary times, we should strengthen exercise and build up our physique, especially in the fight against dizziness. For example, we should do more turning, rotating in place, rolling and other sports, so as to alleviate the carsickness
