How is motion sickness caused? time
When riding a car or taking a boat, it is stimulated by vibration and shaking, which makes the inner ear of the human body unable to adapt and adjust the balance of the body well, which makes the sympathetic nerve excited and causes neurological dysfunction, causing dizziness, vomiting and other carsickness symptoms.

Causes of carsickness

First, the physiological basis of motion sickness: the semicircular canal is a receptor that feels positive and negative rotational acceleration. When the semicircular canal is over-sensitive or over-stimulated, it will cause a series of autonomic reactions, such as carsickness.

Second, the individual differences of carsickness.

External cause

1. When the incoming balance stimulus is too strong, such as sudden braking and violent rotation, even if the balance system is safe and normal, people will feel dizzy, which is a normal physiological phenomenon. However, some people have poor tolerance and react strongly to slight balanced stimuli.

2. Poor sleep and overwork are easy to happen.

Hunger and satiety are also easy to happen.

4. When you have some ear diseases, it will happen.

5. The closed carriage makes the air not circulate, or the smell of some substances is irritating, such as gasoline.

6. Seeing a car has a serious conditioned reflex, and seeing or thinking about a car (especially a bus) will make you carsick.

internal cause

1. Individual sensitivity is different.

2. Psychological reasons.

3. Lack of vitamin b 1

symptom

In life, some people often feel dizzy, upset in the upper abdomen, cold sweat and even vomiting soon after getting on the bus. Especially when the car brakes suddenly, turns sharply or starts suddenly, it can be gradually relieved or recovered after getting off for a period of time. Some people's carsickness symptoms can last for several days. When carsick, you should close your eyes and lie on your back. When sitting, keep your head close to a fixed chair back or object to avoid swinging greatly. The environment should be quiet and well ventilated. At the same time, Foshan Wanying ointment and Huoluo oil must be applied to Tang Yin or temples on both sides of the head, or navel.

Prevention and treatment of carsickness

The simplest, most effective and practical way is to put on headphones to listen to music and turn up the volume, which can interfere with the inner ear's response to balanced stimulation. Other common methods are:

1. People who often get carsick can take Haloning, 25 mg for adults and 25 mg for children before taking the bus to prevent carsick reaction.

2. Take the bus after eating too much or being too hungry.

Don't overwork before riding, sleep well the night before.

4. You can sit in the front of the car to reduce bumps, open the window to make it well ventilated, then tilt your head back in a fixed position and close your eyes to reduce dizziness caused by head vibration and flying eyes.

5. When vomiting, you can take Yunning or metoclopramide. You can take sedatives when you are nervous, such as valium.

6. Exercise should be strengthened at ordinary times to enhance physical fitness, especially in anti-dizziness, such as turning your head, spinning in place, rolling around and other sports, which can alleviate motion sickness.

7. You can wear an electronic anti-vertigo and anti-vomiting instrument to Neiguan point about 10 minutes before getting on the bus. * * There are 1-5 files. Choosing the right gear according to your own comfort and sitting in a place with good air circulation will have a significant effect on relieving carsickness.

8. Take a deep breath when the car is stepping on the accelerator, braking and rotating, which can relieve the symptoms.

9. Acupoint massage. Use your right thumb to point Hegu point in the middle of the tiger's mouth.

10. Press the Zhongshan point, which is at the midline in front of the body and between the nipples.

1 1. Half an hour before the bus ride, the navel was pasted with Fengshi Zhitong cream, and the effect was obvious. The navel is the Shenque point, which is often praised by health experts as the "fortress" of health care. The main thing here is to stimulate the awake brain)

Prevention of carsickness

1. Dizzy. 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. you can also take diazepam 1 tablet and vitamin B 1 tablet, and take them with warm water 40 minutes before taking the bus, which can also prevent carsickness.

4. Take fresh ginger 1 slice or fresh potato 1 slice and stick it on Shenque point (navel) and cover it with Shangshi ointment. At the same time, paste the Shangshi Zhitong ointment on Neiguan point, gently rub the point with your fingers, and you can also contain a piece of fresh ginger in your mouth, which also has a certain preventive effect.

5. Metoclopramide: Metoclopramide 1 tablet, 2 tablets can be taken in case of serious carsickness, and children should reduce the amount as appropriate, and swallow it 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.

6. 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.

7. 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.

8. 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.

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

10. Pinch Neiguan point: When you are carsick, you can pinch Neiguan point with your thumb (Neiguan point is on the palm of your wrist, between your fingers, and between the two tendons on the wrist transverse stripes).

1 1. You can wear the electronic anti-vertigo and anti-vomiting instrument to Neiguan point about 10 minutes before getting on the bus. * * There are 1-5 files. Choosing the right gear according to your own comfort and sitting in a place with good air circulation will have a significant effect on relieving carsickness.

12. When there is no medicine, people with carsickness can tighten their belts before getting on the bus to prevent their internal organs from shaking excessively. After getting on the bus, try to keep your eyes on distant objects as little as possible, especially when going downhill, pay attention to the grip to slow down the impact of inertia on 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 they feel a little uncomfortable, they should choose to rely on the car immediately.

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.

13. Circle exercise can help you get rid of motion sickness: According to Life Times, exercise is a good motion sickness medicine. The most important reason for motion sickness and seasickness is poor balance, which is related to vestibular organs of the inner ear. And some sports with rotating and tumbling events can improve these two abilities.

For example, spiral staircase training, drum training, but the intensity is greater, physical fitness is good, and the equipment conditions can be tried; For people with average physical strength, "standing on one leg" is more suitable for them: hands akimbo, eyes closed, one leg lying on the ground; If you are a child, you can ask him to hold an adult's leg or a tree in circles, and exercise once a day for about 15 minutes each time, and gradually increase the number of circles.

If you persist in exercising for a period of time, the balance ability and adaptability of vestibular organs in inner ear will be greatly enhanced. If you don't feel uncomfortable after 30 to 50 turns, you will get rid of the dizziness of the car and enjoy the trip happily.

A good way to treat motion sickness and seasickness

1. Foot massage therapy

Half an hour before the bus ride, rub your thumb and forefinger moderately for five minutes. At the same time, with deep breathing, you can prevent carsickness.

2. Hand massage therapy

Rub your thumb carefully for 3-5 minutes before taking the bus. In addition, you can also massage the heart reflex area with your thumb.

3. Ear massage therapy

Pinch the tip of the auricle with your thumb and forefinger, and lift, pinch, knead and knead it upward. When kneading, the intensity should not be too large, so that the two auricles are congested and red.

Other treatments

1, take it easy. Keep relaxed and don't always think about dizziness. You'd better find someone to talk to and relax.

You should have enough sleep before traveling. Adequate sleep will make you feel better and improve your ability to resist sports stimuli.

3. It is not advisable to be too hungry or too full by means of transportation. Eating can only be seven or eight points full, especially high-protein and high-fat foods, otherwise it is prone to nausea and vomiting.

4. Try to sit in a seat that is relatively stable and consistent with the direction of movement. Keep the air circulating.

5, the head is properly fixed to avoid excessive swing.

6. Take motion sickness medicine orally half an hour before taking the bus.

7. Try not to look at the fast-moving scenery outside the window. You'd better close your eyes. If a sandman invades you, congratulations! In addition, some people tried to stick a traumatic pain-relieving ointment on the navel, which had a certain effect, but the mechanism remains to be discussed.

8. Take motion sickness medicine. For example, Halo Haining, taken half an hour before the bus ride, is suitable for adults or children over 6 years old. Metoclopramide tablets should be taken 15 ~ 30 minutes before the bus ride or half an hour before the meal. General carsickness patients take 5mg (1 tablet), and severe patients take 10mg (2 tablets).

9. Fresh ginger. Hold fresh ginger slices in your hand and smell them at any time while driving, so that the spicy taste can be inhaled into your nose. You can also stick a piece of ginger on your navel and fix it with Shangshi Zhitong ointment.

10, fresh orange peel. Before getting on the bus 1 hour or so, aim the fresh orange peel at the two nostrils and squeeze, and inhale the fragrant oil mist.

1 1. essential oil. Rub the essential balm on the temples, or drop two drops of essential balm on the navel, and cover it with the ointment for relieving dampness and pain.

12. vinegar drink a cup of warm water with vinegar before taking the bus.

13. Zhitong ointment. Before taking the bus, take the ointment for treating dampness and relieving pain and stick it on your navel.

14. When you feel a little sick in your throat or stomach and want to vomit, cough hard. If you don't feel well, you will vomit soon, so you don't have to cough any more.

Always carsick. Try swinging.

People can perceive the changes in the position and movement of the head, trunk and limbs, which mainly depends on the vestibular function of the inner ear besides the proprioception of vision, joints and muscles. Vestibular organs can be roughly divided into semicircular canals and otoliths, which have extremely sensitive sensory devices. The semicircular canal feels the stimulation of the change of head rotation movement through the flow of endolymphatic; Otoliths feel the stimulation of body tilt and linear motion through the gravity of otoliths. The central nervous system regulates the tension of muscles in various parts of the body and maintains the normal posture of the body.

For people with vestibular dysfunction or excessive sensitivity, sudden changes in head position and movement speed can cause dizziness, nausea and vomiting, thus affecting the balance of the body. However, when specific stimuli repeatedly act on vestibular organs, after a period of time, vestibular response will gradually weaken, and the stability of vestibular function will be strengthened through active training. This phenomenon is called vestibular acclimatization.

This is why figure skaters and dancers can spin freely and quickly. Swing is the simplest and cheapest training method to enhance the stability of vestibular function, establish habits and improve the balance ability of human body. The fitness mechanism of traditional sports, which has lasted for more than 2500 years, has been gradually revealed by modern science.

When swinging, people swing back and forth with the swing board, and the direction and speed of movement, potential energy and kinetic energy, and the height from the ground are constantly changing. The body is in a rapid change between overweight and weightlessness, and the air pressure in the ear cavity fluctuates. In this way, vestibular sensory cells will be stimulated by the constant change of endolymphatic flow and otolith gravity, and the nerve impulse generated by the change of membrane potential will relieve vestibular organs alternately from acute to chronic. This can improve the adaptability and stability of sensory cells. This is the basic mechanism of swinging to exercise vestibular balance acclimatization. People who often swing rarely get carsick. The higher the swing, the longer the time, and the better the acclimatization effect.

The fitness effect of swinging is systemic. While constantly overcoming tension and fear, it can enhance psychological endurance and self-control; When the limbs and head are limited, skeletal muscle contracts and relaxes rhythmically, which is also beneficial to the increase of muscle fiber volume.

There is no cure for carsickness. Motion sickness refers to cold sweat, nausea, vomiting, dizziness and other symptoms when riding a car, and its specific mechanism is not completely clear. According to an old Chinese doctor, carsickness is related to people's physique. At present, there is no long-term treatment for carsickness, but there are many short-term treatments for carsickness, including drugs and some folk remedies.

People with carsickness can learn to drive, and the relevant laws do not stipulate that people with carsickness cannot learn to drive. In the actual learning process, few people give up learning to drive because of carsickness.

1 1. Wear comfortable clothes, not too tight clothes, and try to wear loose clothes.

12. Try to sit in the front seat of the bus when traveling. The position above the tire has a strong vibration force, which makes people feel bumpy. People who have the habit of getting dizzy by car should try to avoid sitting in this seat.

13. Don't read books or magazines during the trip, but try to see the distant scenery.

14. If dizziness is serious, you can bite your fingers or pinch your thighs to send a message to your brain that pain interferes with motion sickness, which can also relieve motion sickness to varying degrees.

Six ingenious methods for treating dizziness

Many people get carsick and seasick. Experts say that in this case, taking some measures will help alleviate:

1. Relax

If there is motion sickness, seasickness, etc. First of all, don't be nervous and try to relax; You can also change your sitting posture appropriately. If you sit by the window, you can open the window, breathe fresh air and adjust your mood.

take medicine

Anti-dizzy drugs, mainly sedative and antiemetic drugs, such as Cheng Yunning and Diazepam, are used to inhibit central excitement and relieve gastrointestinal spasm. Take 1 to 2 capsules with warm boiled water, and reduce the dosage for children.

Apply essential balm

Apply essential balm to temples or Fengchi points. You can also drop two drops on your navel and cover it with Shangshi Zhitong ointment.

Clever use of orange peel

The surface of fresh orange peel is folded in half outward and inward, and then the finger is pointed at the two nostrils to squeeze, which will spray a fragrant oil mist from the peel. You can smell it at any time on the way

5. Press acupoints

When carsick, you can pinch Neiguan point with your thumb (Neiguan point is located on the palm of wrist joint, between two horizontal fingers, and between two tendons on wrist transverse stripes) for 3 ~ 5 minutes, and press it appropriately until you feel sore.

Close your eyes.

Try not to look at the fast-moving scenery outside the window. You'd better close your eyes. If a sandman invades you, congratulations. Sleeping is the simplest and most economical anti-dizziness prescription.

I hope you are in good health, and I hope you can adopt the wolf cub and go home to serve you.
