Symptoms of motion sickness and treatments for motion sickness

　　If you want to know more, take a look together.

　　1. External causes of motion sickness. The physiological basis of motion sickness: the semicircular canals are receptors that sense positive and negative rotational acceleration. When the semicircular canals are overly sensitive to stimulation or receive excessive stimulation, a series of autonomous functional reactions will occur, such as motion sickness.

　　1. When the incoming balance stimulus is too strong, such as sudden braking or violent rotation, people will feel dizzy even when the balance system is safe and normal. This is a normal physiological phenomenon. However, some people have poor tolerance and have strong reactions to slight balance stimulation.

　　2. It is easy to occur when you have poor sleep and are overworked.

　　3. It is also easy to occur when you are too hungry or too full.

　　4. Suffering from certain ears disease Can happen at any time.

　　5. The compartment is sealed so that the air does not circulate, or the smell of certain substances, such as gasoline, is irritating.

　　6. When seeing a car, a severe conditioned reflex occurs, and you will get motion sickness when you see or think of a car.

　　2. The internal causes of motion sickness include personal sensitivity and psychological effects.

　　1. It may be due to spontaneous degeneration of the utricle that the otoliths fall off from the cystic plaque and are deposited on the posterior ampulla ridge.

　　2. Inflammation or trauma can also induce this disease. For example, during viral labyrinthitis or chronic suppurative otitis media, leukocytes, phagocytes or endothelial debris enter the endolymph; during brain trauma or stapes surgery, blood enters the endolymph and can form tangible particles that are deposited on the top of the ampulla crest. Barber reported that 47% of patients with longitudinal temporal bone fractures may experience positional vertigo, and 20% of patients without fractures may also experience this symptom. Dix and Hallpike (1952) reported 100 cases of otitis media, 26% also had positional vertigo. Ear surgeries such as tympanoplasty and mastoidectomy that damage the vestibule may also cause this disease.

　　3. Lindsay and Cawthorne pathological findings, anterior vestibular artery and superior vestibule nerve The utricle, superior semicircular canal and lateral semicircular canal with branched branches are degenerated, while the saccule and posterior semicircular canal are normal. Therefore, it is believed that hypertension, heart disease and insufficient blood supply from the vertebral artery can cause embolism of the anterior vestibular artery, causing the otolith membrane to degenerate and fall off, and deposit on the ampullar crest.

　　4. Gammaglobulinemia, globulin deposition on the ampullae ridge, or the thinning of the ampullae ridge due to alcohol in alcoholics, can all produce this characteristic. When severely deaf children wear high-intensity (120-130dB) hearing aids, about half develop positional vertigo.

　　This is called "motion sickness".

　　Symptoms and manifestations of motion sickness

　　Motion sickness has some of the following symptoms and manifestations.

　　1. A person is stimulated. Motion sickness is medically known as "motion sickness" or "motion sickness". Motion sickness is a general term for motion sickness, seasickness, airsickness, etc. It is directly related to the vestibular balance receptor of our inner ear. To be precise, motion sickness is not a real disease. It is different from a disease in the usual sense. It is just an emergency response of a sensitive body to excessive stimulation. Dizziness or even vomiting while riding in a car. In daily life, some people often feel dizzy, uncomfortable in the upper abdomen, nausea, cold sweat, or even vomiting soon after getting in a car. This is especially worse when the car brakes suddenly, makes a sharp turn, or starts suddenly. The symptoms can be gradually relieved or recovered after getting off the car and resting for a while. For some people, symptoms of motion sickness can last for several days.

　　2. The body loses its balance. The human body can judge direction and maintain its own balance, mainly by skin shallow receptors, Eye , the deep receptors in the neck and body, and the inner ear are jointly responsible, of which the inner ear is the most important. The semicircular canals of the inner ear as well as the utricle and saccule have primarily a balancing function. There are three semicircular canals, which are perpendicular to each other and form three sides of space. They receive external balance stimulation and transmit it to the balance center of the cerebral cortex through the vestibular nerve to regulate and manage the balance response.

　　3. Various physiological discomforts occurred. In daily life, some people often feel dizzy, uncomfortable in the upper abdomen, nausea, cold sweat, or even vomiting soon after getting in a car. This is especially worse when the car brakes suddenly, makes a sharp turn, or starts suddenly. The symptoms can be gradually relieved or recovered after getting off the car and resting for a while. For some people, symptoms of motion sickness can last for several days.

　　4. It may be due to spontaneous degeneration of the utricle that the otoliths fall off from the cystic plaque and are deposited on the posterior ampulla ridge.

　　5. Induce other symptoms. Inflammation or trauma can also induce this disease. For example, in the process of viral labyrinthitis or chronic suppurative otitis media, leukocytes, phagocytes or endothelial debris enter the endolymph; in brain trauma or stapes surgery, blood enters the endolymph and can form tangible particles that are deposited on the top of the ampulla crest. Barber reported that 47% of patients with longitudinal temporal bone fractures may experience positional vertigo, and 20% of patients without fractures may also experience this symptom. Dix and Hallpike (1952) reported 100 cases of otitis media, 26% also had positional vertigo. Ear surgeries such as tympanoplasty and mastoidectomy that damage the vestibule may also cause this disease. There are other complications. Lindsay and Cawthorne's pathology found that the utricle, superior semicircular canal, and lateral semicircular canal distributed by the anterior vestibular artery and superior vestibular nerve branches were degenerated, while the saccule and posterior semicircular canal were normal. Therefore, it was believed that hypertension, heart disease, and insufficient blood supply from the vertebral artery could cause embolism of the anterior vestibular artery, resulting in degeneration and detachment of the otolith membrane and deposition on the ampullar ridge.

　　Don’t underestimate motion sickness. If this happens, resolve it as soon as possible.

　　Treatments for motion sickness

　　Here are some measures to deal with motion sickness.

　　1. Distract attention. The simplest, most effective and practical way is to wear headphones to listen to music and turn the volume up a bit, which can interfere with the human inner ear's response to balanced stimulation.

　　2. Eat haoning. Take 1 to 2 tablets with warm boiled water 40 minutes before boarding a car or boat, the dosage may be reduced for children.
