About motion sickness and seasickness:

1. Why do you get seasick, carsick and airsick?

Motion sickness, also known as motion sickness, is a general term for motion sickness, seasickness and airsickness. It refers to cold sweat, nausea, vomiting, dizziness and other symptoms caused by excessive exercise stimulation of vestibular balance receptors in human inner ear and excessive bioelectricity of vestibular organs when riding vehicles.

The vestibular organ of the inner ear is the balanced sensory organ of the human body, including three pairs of semicircular canals and the oval sac and balloon of the vestibule. There is ampulla crest in semicircular canal and otolith (also called capsule point) in elliptic capsule, which is the vestibular terminal receptor and can feel the stimulation of various specific motion States. The semicircular canal is stimulated by angular acceleration (deceleration), while the balloon of elliptical sac and balloon is stimulated by horizontal or vertical linear acceleration (deceleration). When the vehicle we ride rotates or turns (for example, the car turns and the plane moves in circles), the angular acceleration acts on the corresponding semicircular canals on both sides of the inner ear. When the hair cells in the ampulla of a semicircular canal are stimulated to bend and deform to produce positive potential, the opposite hair cells bend and deform to produce negative potential (negative voltage), and the exciting or inhibiting electrical signals of these nerve endings are transmitted to the vestibular center through nerves and perceive this movement state; Similarly, when the vehicle has linear acceleration (deceleration) changes, such as car starting, acceleration and deceleration braking, ship shaking and bumping, elevator and airplane lifting, etc., these stimuli cause deformation and discharge of hair follicle hair cells in vestibular elliptic sac and balloon, which are transmitted to the center and are perceived. The generation and transmission of these vestibular electrical signals will not cause adverse reactions within a certain limit and time, but everyone's tolerance for the intensity and time of these stimuli is limited, and this limit is the vertigo threshold. If the stimulus exceeds this limit, there will be motion sickness symptoms. Everyone's tolerance varies greatly, which is not only related to genetic factors, but also influenced by vision, individual physique, mental state and objective environment (such as air smell). Therefore, under the same objective conditions, only some people have motion sickness symptoms.

2. How to prevent and treat carsickness (seasickness, carsickness, airsickness)?

Accurately speaking, carsickness is not a real disease, which is different from the usual diseases. It's just an emergency response of sensitive organisms to over-limit stimuli. Therefore, there is no real radical cure or cure, and the existing prevention and treatment methods are to temporarily relieve symptoms or delay their occurrence.

The best way to prevent and treat motion sickness is to avoid or leave the environment that can cause motion sickness, but this is unrealistic. In the past, many drugs were used to prevent and treat motion sickness, mainly sedative and emetic drugs, such as Cheng Yunning, scopolamine, diazepam, etc., to inhibit central excitement and relieve gastrointestinal spasm. However, these drugs have many side effects, slow action, dry mouth and drowsiness, and the curative effect is not ideal. There is a skin patch behind the front ear, which is a slow-release scopolamine. It can be absorbed through the skin, but it still cannot eliminate the inherent side effects of the drug. Other methods, such as sticking navel, pressing Neiguan point, opening window for ventilation and looking forward, are also commonly used, and the effect is extremely limited. There is also vestibular exercise, which, like pilot training, repeatedly stimulates the vestibule for a long time, such as swivel chair, swing, crouching tiger, rowing and so on. To make the vestibule adapt to the habit can achieve the purpose of relieving motion sickness symptoms. But if you stop training or leave the exciting environment, the symptoms of motion sickness will reappear.

In the past, vestibular balance medical experts from all over the world have been committed to the prevention and treatment of motion sickness for a long time, but with little effect, there has been no breakthrough. Now, Professor Hu Guang Ai, director of the Otolaryngology Research Institute of Tianjin No.1 Central Hospital and director of the Vertigo Diagnosis and Rehabilitation Center, and the chief physician, after more than ten years of clinical research, have invented an electronic anti-motion sickness instrument according to the principles of vestibular balance medicine and classical vestibular clinical theory. The instrument generates pulsed electrical signals through electronic oscillation, and then acts on the vestibule, the balance organ of human inner ear, through binaural electrodes, so as to counteract or weaken the excessive bioelectricity generated by excessive movement-linear and angular acceleration (deceleration) stimulation, reduce and prevent vestibular nerve impulses from transmitting to the center, thus improving the tolerance of vestibular organs to various sports stimuli and achieving the purpose of treating motion sickness. This is a brand-new and pioneering treatment for carsickness. In the process of use, users can always keep a clear head, change the state of irritability, thirst and drowsiness when taking sedatives in the past, and make today's journey chic and brisk, so that they can enjoy the beautiful scenery of the motherland and the happiness of modern civilization.

The research project was rated as "the first in the world" by experts, and won the Tianjin Science and Technology Progress Award, the National Invention Expo Silver Award and the national patent (98 3 26062.438+0) successively, and was listed as a scientific and technological innovation promotion product in Tianjin. This product (No.:22603 1, No.98, Jin (Zhun)) was put on the market and was immediately praised by the majority of carsickness patients.

3. Why do carsick people drive or not?

Because carsickness is mainly caused by excessive stimulation of human vestibular nervous system, the excitability of vestibular nervous system is the key. The vestibular nervous system belongs to the low-level center, which is influenced by the high-level center of cerebral cortex, and the high-level center has inhibitory effect on the low-level center. People with carsickness are in a highly concentrated state when driving, and the high excitement of the advanced cerebral cortex inhibits the vestibular system, so naturally they will not get carsick. But when riding as a passenger, there is no such effect. Similarly, when the battle alarm sounded, sailors who were originally seasick were immediately able to fight high.

4. Why do some people get carsick, but they don't get carsick after fainting?

Good vestibular function of inner ear is one of the basic conditions for motion sickness (seasickness, carsickness, airsickness). If the vestibular function is lost, the human body will lose the ability to accept all kinds of acceleration (deceleration) sports stimuli, that is, all kinds of bad or over-limit stimuli that cause motion sickness will lose their effect on the human body. Therefore, some people with bilateral vestibular dysfunction (ototoxic drug poisoning, bilateral labyrinthine resection, repeated vertigo attacks, etc. ) After getting dizzy, you won't get carsick.

5. Why do carsick people get carsick more easily with the more advanced means of transportation?

Although the vestibule of the inner ear has a good function and can accept all kinds of acceleration (deceleration) stimuli, which is one of the basic conditions for motion sickness (seasickness, carsickness and airsickness), a certain range of acceleration (deceleration) stimuli are suitable for motion sickness, but those high-frequency bumps (produced by ordinary vehicles) are not suitable, but the surging acceleration and shaking produced by vehicles with good balance are most suitable for vestibule. Therefore, the more advanced the vehicle, the easier it is to get carsick.

6. Will the smell of gasoline make you carsick?

Motion sickness is caused by excessive stimulation of the vestibule of the inner ear. The smell of gasoline may aggravate the nausea of some carsickness patients, but it is not the cause of carsickness. Imagine staying at home and smelling gasoline will make you carsick? As for some people who are allergic to gasoline, that is another matter.

Various methods to prevent carsickness

1, riding dizzy (dizzy stop). Take 1 to 2 capsules with warm boiled water 40 minutes before taking the bus or boat, and reduce the amount for children.

2, cold. In the absence of dizziness, you can use Ganmaotong instead, the method is the same as above, and the effect is the same.

3. Diazepam 1 tablet and vitamin B 1 tablet can also be taken with warm water 40 minutes before boarding the bus, which can also prevent carsickness.

4. Take 65,438+0 slices of fresh ginger or 65,438+0 slices of fresh potato and stick it on Shenxiejue (navel) and cover it with Shangshi ointment. At the same time, paste Shangshi Zhitong ointment on Neiguan point and gently rub the point with your fingers. You can also put a piece of fresh ginger in your mouth, which also has a certain preventive effect.

1. metoclopramide: metoclopramide 1 tablet, and you can take 2 tablets in case of serious carsickness. The dosage of children should be reduced as appropriate, and swallowed 10 ~ 15 minutes before getting on the bus to prevent carsickness. If you travel for more than 2 hours and have motion sickness symptoms, you can take 1 tablet again. Those who take medicine temporarily on the way should stand 15 ~ 20 minutes after taking medicine and sit down to take medicine. The effective rate of this method is 97%, and there are no side effects such as dry mouth and dizziness caused by other motion sickness drugs.

5. Orange peel: Before getting on the bus 1 hour or so, fold the surface of fresh orange peel outward and inward, and then squeeze it at two nostrils, and the fragrant oil mist will be sprayed from the skin. Inhale 10 times or more, and inhale at any time on the way.

6. Fengyoujing: Apply Fengyoujing to temples or Fengchi points during the ride. You can also drop two drops of essential balm on your navel, and cover it with Shangshi Zhitong ointment.

7. Vinegar: Drink a cup of warm boiled water with vinegar before taking the bus, so it is not easy to get carsick on the way.

8. Shangshi Zhitong Ointment: Take Shangshi Zhitong Ointment and stick it on the navel before taking the bus to prevent carsickness.

9. When there is no medicine, carsick people can tighten their belts before getting on the bus to prevent their internal organs from shaking too much. Try to look at distant objects with your eyes as little as possible after getting on the bus, especially when going downhill, pay attention to grasping the hand to slow down the impact of inertia on the internal organs, and pay attention to ventilation in a tightly sealed car or a car with heavy gasoline smell, which will help prevent carsickness. If you feel a little uncomfortable, you should immediately choose the right seat in front of the car to sleep and sleep.

Those who have a history of carsickness can drink some hot and sour appetizing food before taking the bus, and do not eat sweets and greasy food to avoid being too hungry and full.

A good way to treat motion sickness and seasickness

Zhan Peiyuan, an attending physician in the Department of Neurology of Guangdong Province, said that motion sickness and seasickness are very common phenomena, which have organic reasons, functional and psychological reasons. Among children, the incidence rate of boys is higher than that of girls, while the incidence rate of adults is higher.

Usually we are used to walking on the ground, but we are not used to unfamiliar sports stimuli, such as bumping up and down and vacillating when riding a car, taking a boat or flying. Some healthy people have no organic diseases and dysfunction, but after being stimulated by strenuous exercise in different directions and at different speeds, they may have symptoms such as motion sickness, seasickness and airsickness, such as dizziness, pallor, nausea and vomiting. This is a very normal physiological reaction. As long as people get rid of the stimulating environment, the symptoms will disappear naturally.

The symptoms of motion sickness often develop gradually, from stomach discomfort to nausea, cold sweat and finally vomiting. Motion sickness can be prevented. Although everyone's physique and sensitivity are different, and some people are particularly sensitive, there are still ways to help these people who are prone to carsickness avoid carsickness.

(1) Strengthen physical exercise and enhance the tolerance of vestibular organs. Motion sickness mostly occurs in people with sensitive vestibular organs. Therefore, pay more attention to exercise, turn around, bend over and squat to increase the tolerance of vestibular organs.

(2) Overeating, fatigue, lack of sleep, dirty air, emotional stress and special smells such as gasoline and lampblack may all contribute to the occurrence and aggravation of carsickness, and these unfavorable factors should be avoided.

(3) Specialized vestibular training. Motion sickness can be prevented by rehabilitation training, such as repeated boat and car training, to improve the adaptability of vestibular organs to irregular movements. In addition, people who are afraid of carsickness can often participate in some activities, especially those that help to adjust the balance of human body position, such as swinging, sliding, parallel bars, rolling on the mat, etc., which can improve the adaptability of vestibular organs.

(4) When riding or taking a boat, try to limit the head movement, and rest your head on the back of the chair to reduce acceleration stimulation, especially rotation stimulation. If possible, try to lie flat.

(5) Avoid bad visual stimuli. Look out of the window less when riding, and it is easier to induce motion sickness by reading by car or boat, so closing your eyes can reduce the occurrence of motion sickness.

You can eat some yihanning buccal tablets before taking the bus to prevent carsickness. Anticholinergic drugs can inhibit cerebral cortex and prevent dizziness and vomiting.

Exercise for motion sickness and seasickness.

Traveling by car and boat, most people can adapt well. But for some carsick people, this is an arduous task. Every time these people travel by boat, they are dizzy, disgusting, bored and uncomfortable. At the worst, they are dizzy, upset and miserable.

Motion sickness is a general term for motion sickness, seasickness, airsickness and other diseases caused by factors such as shaking, bumping, rotating and accelerating exercise. People who are prone to carsickness,

Vestibular organ, the balance organ of the inner ear, has poor adaptability to irregular posture changes such as rotation. Of course, there are other inducing factors of carsickness, such as high temperature, high humidity, poor ventilation, noise, bad smell, emotional tension, lack of sleep, excessive fatigue, hunger or satiety, physical weakness and so on.

Medical experts point out that motion sickness can be treated by exercise. Usually, patients can consciously do some swinging and rotating movements, such as bending over, shaking their heads, standing step by step repeatedly, and do some large-scale rotating movements after getting used to it, such as slowly rotating the body left and right alternately with the help of a swivel chair. Through gradual exercise, the adaptability of vestibular organs of the inner ear to irregular movements can be enhanced, and motion sickness can be gradually alleviated or even overcome.
