The matter of motion sickness, everyone who understands it understands
When it comes to motion sickness, people who have not experienced it may have no concept, while those who have experienced it will be impressed, and seriously will leave a psychological shadow, or even refuse to travel by car.
Motion sickness, medically known as "motion sickness.".
This disease is mainly manifested as nausea and vomiting, dizziness, cold sweat, breathing difficulties and other symptoms, resulting in uncomfortable pain, but also caused a lot of inconvenience to other passengers around.
Why do I get motion sickness? Is it because of bad health?
In fact, motion sickness is most likely related to the vestibular organs of the inner ear of the human body.
The vestibular organ of the inner ear is the body's balance-sensing organ, which includes the oval sac of the vestibular sac, the spherical sac, and three pairs of semicircular canals. The semicircular canal has an oval sac, a judial crest, an otolith, and a spherical sac.
They belong to vestibular peripheral receptors and can feel stimuli in a variety of different motility states.
When the car starts, brakes, accelerates, slows down, rocks and bumps, and raises and lowers the plane, these stimuli are deformed and discharged on the follicular hair cells of the vestibular oval sac and spherical sac, and are transmitted towards it, so as to quickly perceive.
With the occurrence and transmission of these vestibular signals, people will have a variety of adverse reactions within a certain period of time, but there is a certain limit to the time tolerance and intensity of these stimuli in each person, that is, the halo threshold.
When the vestibular organs of the inner ear are stimulated beyond this limit, the corresponding symptoms of motion sickness occur.
Different people, their tolerance is quite different, not only genetic factors lead to differences, personal physique, vision, psychological state and objective environment also have a significant impact on it.
Therefore, under the same objective conditions, some friends are only a little dizzy when they get motion sickness, and some friends may vomit and have difficulty breathing.
What should I do if I experience motion sickness? You can take the following approaches:
First, lie down with your eyes closed
Patients should lie on their backs, close their eyes, let their mood calm, do not look at the scenery outside the car, it is easy to think that they are not in a shaky environment, the perception of the vestibular organs of the inner ear will not be so strong, and the phenomenon of motion sickness will slowly reduce.
Second, back to the seat
When sitting, put your head close to the back of a fixed seat or other object, which can effectively avoid large swings of the body.
Third, pay attention to ventilation
In a ventilated environment, people are stimulated by fresh air, which helps to concentrate and calm the breath and reduce the symptoms of vertigo.
Fourth, take medication
Before getting on the bus, you can prepare some anticholine, antihistamine and other drugs in advance, such as theaphenhydramine, chlorpromazine, scopolamine hydrobromide, metoclopramide, diazepam, betasteine hydrochloride, mecrozine hydrochloride and the like.
When you feel that you are a little dizzy, appropriate taking these drugs can inhibit the exudation of blood vessels for a certain period of time, and can also play a calming role, and the phenomenon of motion sickness can be naturally alleviated.
Fifth, spare a small bottle of wind oil essence
When going out to take various means of transportation, carry a small bottle of wind oil essence, when you feel motion sickness, take out the wind oil essence to smell the smell, which can also play a role in alleviating motion sickness.
In short, friends who are prone to motion sickness are mostly stimulated by the vestibular organs of the inner ear that exceed their own limits.
For such friends, whenever you want to go out to take a car or plane, try to bring some drugs to relieve motion sickness. Friends who find that there are passengers around them who have motion sickness can try to make them close their eyes and lie on their backs.
In short, motion sickness is not a serious disease, and it can be relieved by itself in most cases.
