1. carsick people take Shangshi Zhitong Ointment 1 tablet one hour before taking the bus and stick it on the liver and navel (called Shenque point). If you ride for more than one day, change to another post the next day. Can effectively prevent carsickness.
2. Fasten your seat belt before getting on the bus to prevent internal organs from swimming excessively in the body, which helps to prevent carsickness.
3. There is a piece of ginger in your mouth. People who love carsickness should take a piece of fresh ginger with them and eat 2 pieces of fresh ginger before getting on the bus, which can greatly reduce carsickness.

Motion sickness, seasickness and airsickness
CCTV International 200365438+February 26th 16:44
Motion sickness is not only related to the individual differences of human body, but also related to the balance system of vestibular balance organs. Vestibular organ is a very important organ of human body. Just as the function of eyes is visual response and the function of nose is olfactory response, the function of ears is to produce hearing, and the function of vestibule is a very important organ to maintain human balance. The vestibule can feel the changes in the position and posture of the human head, and can adjust the posture of the human body at any time to achieve body balance. Look at a model. The vestibule is just outside the cochlea.
How does vestibule play the role of balance?
The vestibule works at any time and anywhere, just as our cochlea can hear sounds at any time and anywhere. The vestibule is always aware of the position of the human body. For example, when a normal bus suddenly brakes, people who are standing tend to lean over, but they will soon control their bodies and will not fall. At this time, the vestibule is working, adjusting its body posture and achieving a balance.
Does it mean that the vestibular function of people with motion sickness is weak?
Can't be easily understood. In fact, the vestibule of carsick people is in a disordered working state. Let's watch a series of short films: this is a beautiful diving scene. When an athlete performs graceful tumbling and jumping, it is the vestibule that accurately judges the position of the body, so as to achieve the action of balancing the body.
So are athletes' vestibular organs more developed than ordinary people?
The vestibular organs of athletes are indeed particularly stable, but at the same time, they must undergo special training to achieve superb balance.
In a small space like a car, the range of activities is actually not large. Why do you get carsick?
If there are some abnormal feelings during running and some special situations during exercise, then there will be motion sickness, such as feeling uncomfortable in the carriage, or the surrounding air is not good, or running often encounters some complicated traffic conditions, which will cause some frequent stimulation to the vestibule. If the tolerance limit is exceeded, there will be some carsickness symptoms such as dizziness, nausea and vomiting.
Why do carsick people vomit?
Some people with carsickness will have symptoms of vomiting. Vomiting is also a very important symptom of carsickness, which usually occurs in patients with severe carsickness. The mechanism of vomiting is that the current chamber will be dysfunctional after being stimulated, and then the autonomic nervous system will be dysfunctional. The function of autonomic nerve is to maintain normal gastrointestinal peristalsis. After the disorder occurs, there will be reverse gastrointestinal peristalsis, which will cause vomiting. In addition, there are some receptors on the inner wall of our stomach. After some bumps between the human body and the car, these receptors will be stimulated or pulled, and then reflex gastrointestinal peristalsis will occur, which will also cause vomiting.
Why don't some carsick people get dizzy when driving?
This situation is because the vestibular nervous system is a complex nerve connection reflex system. If you are in a state of high tension or concentration, you may adjust the sensitivity of the vestibule. At this time, people who usually get carsick by car may not get carsick.
Why is it not easy to get dizzy when sitting in the passenger seat, but easy to get dizzy when sitting in the back seat?
That's true. Most people will give the passenger seat to people who are prone to carsickness. This is because the vision in the back row is not very good, so they can't look forward and will get used to looking sideways. Moreover, the space in front is relatively spacious than the space in the back, so it is easy for people with motion sickness to have a range of activities, and they will feel very relaxed at this time.
Does psychological suggestion work?
There are individual differences in nervous reaction, and some psychological adjustment can balance the stability of this nervous system, so giving yourself some good psychological hints before riding will alleviate the symptoms of carsickness.
Precautions for riding
1, don't eat too much, don't eat greasy food, eat some digestible food early.
2. Choose a well-ventilated seat in the front row by bus, boat or plane, keep your eyes on the front, or close your eyes and don't look at anything passing by the window.
3. Keep a happy mood, calmly suggest that you won't get carsick, remember good times and happy things, listen to music and chat with people.
4. Make sure to get enough sleep before going out to prevent fatigue, and don't read books in cars, boats and planes.

Ginger is a traditional Chinese medicine for treating nausea. Studies have proved that it can relieve nausea caused by motion sickness and seasickness. Professor Sun Weiming of the University of Michigan and his colleagues studied seven healthy people aged 65,438+08 to 35, and put them in a large rotating drum for 30 minutes after meals, which caused motion sickness artificially. Before causing carsickness, take 1 g ginger powder or placebo orally.
When the drum rotates, the nausea index is measured on the scale of 1 to 3. The nausea index of ginger group was significantly lower than that of placebo group, the former was 1.0 on average and the latter was 2.5 on average. After the drum stopped rotating, the nausea index changed from 1 to 10, which was 1.5 in ginger group and 7.8 in comfort group. The time of nausea in the ginger group was also relatively late, with an average of 4.6, and that in the placebo group was 1 1.4.
At the same time, the researchers measured the subjects' gastric electrical activity. When the drum rotates, the gastric contraction amplitude of ginger group is normal, while that of placebo group increases by 7%.
Common anti-motion sickness drugs have obvious side effects, such as dizziness and dry mouth. According to this study, ginger can be an effective substitute for these drugs.

Carsickness is a particularly uncomfortable thing. What should I do?
Get on the bus with ginger in your mouth.
You can cut two slices of fresh ginger commonly used in cooking at home and carry it with you. Putting two pieces of fresh ginger in your mouth before getting on the bus can effectively prevent carsickness caused by smelling gasoline.
Tighten your belt.
If you drink too much liquid before getting on the bus, it is likely to cause stomach motion sickness. You can fasten the belt buckle before getting on the bus, which can protect the internal organs from some car bumps and prevent stomach motion sickness.
Umbilical plaster
One hour before the bus ride, take a piece of Shangshi Zhitong ointment and stick it on your navel, which is Shenque point. Because borneol and musk contained in Shangshi Zhitong ointment will be slowly released in the body through acupoints, it can effectively prevent carsickness. If you ride for more than a day, change another one to make the effect last.
So many methods, enough for you? Hmm. How interesting
