  The theory also explains why some individuals experience motion sickness while viewing a moving field even if they are still. […] Thus far, the sensory conflict and neural mismatch theory is the most widely accepted theory on motion sickness. […] Motion sickness is not a pathological condition in the strict sense. Rather, it is a normal physiological response to real or virtual motion stimuli that occur mostly in individuals with an intact vestibular system. […] Motion sickness can develop in any individual if the movements applied to the body are significant enough. […] However, there is considerable individual susceptibility to motion sickness that might also be a result of gene-environment interaction. […] Certain characteristics are correlated with this susceptibility. […] Motion sickness is more prevalent in individuals who suffer from migraine, vertigo, and Meniere disease.

  Motion sickness is typically triggered by low-frequency lateral and vertical motion (example: air, sea, road transportation) or by virtual simulator motion (video games, virtual simulators). The sensory conflict and neural mismatch theory is the most widely accepted theory for explaining motion sickness. It describes the conflict that occurs between the visual, vestibular and somatosensory systems resulting from real or virtual motion. Afferents from the vestibular apparatus arrive at the vestibular nuclei of the brainstem, which also receives inputs from the visual and proprioceptive systems. Efferent projections then reach the temporoparietal cortex via the posterolateral thalamus, triggering autonomic reactions and the vomiting center. When there is a discrepancy between actual versus expected patterns of vestibular, visual, and kinesthetic inputs, it initiates the cascade of motion sickness symptoms. […] Motion sickness occurs when there is a mismatch between actual versus expected sensory inputs. Although the exact neurobiological mechanism is unclear, many countermeasures have been developed to prevent and alleviate this condition.

• #1 Motion Sickness – Causes and Treatment | familydoctor.org

  https://familydoctor.org/condition/motion-sickness/

  Motion sickness is a sick feeling triggered by movement. It occurs in cars, buses, trains, planes, or boats. It can occur on amusement rides or virtual reality experiences. Seeing the movement of others or things can trigger it. This condition is not life-threatening, however, it can make traveling unpleasant. […] Motion sickness is common in older people, pregnant women, and children between the ages of 5 and 12. Also, it’s common in people who have migraine headaches. It may be genetic. Once the motion stops, you’ll gradually feel better. In rare cases, the condition is triggered by a problem with your inner ear. This could be due to fluid buildup or an ear infection. Parkinson’s disease is another cause of the condition. […] Motion sickness is an imbalance between what you see and what you feel. In the car, the car is moving forward. However, your body is standing still. This imbalance is what causes you to feel sick.

• #1 Why do I get motion sickness ?

  https://www.dramamine.com/blog/4-reasons-you-might-be-prone-to-motion-sickness

  Motion sickness occurs when your brain receives conflicting signals from different sensory systems within your body that register motionyour inner ears, eyes, muscles and joints, and nerves in the skin. […] If youve never had motion sickness before and suddenly experience it in a car or other mode of transportation, you may be feeling the side effects of a medication youre taking or of another medical condition. […] People who get migraines are also more likely to get motion sickness. […] Motion sickness is most common in children, though children do tend to grow out of it. […] Pregnant women, especially those with morning sickness, are more likely to get motion sickness or feel nauseated when traveling than non-pregnant women. […] Women are more likely than men to get motion sickness. The female hormone estrogen may be to blame as a spike in estrogen levels may cause or increase susceptibility to nausea.

• #1 Motion sickness – Wikipedia

  https://en.wikipedia.org/wiki/Motion_sickness

  Motion sickness occurs due to a difference between actual and expected motion. […] The cause of motion sickness is either real or perceived motion. […] Motion sickness can be divided into three categories: Motion sickness caused by motion that is felt but not seen i.e. terrestrial motion sickness; Motion sickness caused by motion that is seen but not felt i.e. space motion sickness; Motion sickness caused when both systems detect motion but they do not correspond i.e. either terrestrial or space motion sickness. […] Motion sickness is caused by a conflict between signals arriving in the brain from the inner ear, which forms the base of the vestibular system, the sensory apparatus that deals with movement and balance, and which detects motion mechanically. […] The sensory conflict theory notes that the eyes view motion while riding in the moving vehicle while other body sensors sense stillness, creating conflict between the eyes and inner ear. […] According to sensory conflict theory, the cause of terrestrial motion sickness is the opposite of the cause of space motion sickness.

• #1 Motion Sickness: Causes, Symptoms, Treatment, and More

  https://resources.healthgrades.com/right-care/symptoms-and-conditions/motion-sickness

  Motion sickness happens when the reality of movement and the perception of movement are not the same. For example, you are sitting still in a car, but your vestibular system senses head movement, which is the movement of the car. This results in you feeling unwell. […] The exact neurobiological reason that some people experience motion sickness is not known. However, it is thought to be the result of your body feeling unbalanced in some type of moving vehicle, causing confusion in your senses. […] Some common causes of motion sickness include: car rides, train rides, air travel, amusement rides, video games or virtual reality. […] Specific circumstances that may cause motion sickness include: not having enough air circulation while in the car, reading in the car, experiencing turbulence while on a plane, feeling the rocking of a boat, sitting in the backseat of a car and being unable to see the horizon.

  Motion sickness is a symptom complex that usually includes nausea, often accompanied by vague abdominal discomfort, vomiting, dizziness, pallor, diaphoresis, and related symptoms. It is induced by specific forms of motion, particularly repetitive angular and linear acceleration and deceleration, or as a result of conflicting vestibular, visual, and proprioceptive inputs. […] Motion sickness is a normal physiologic response to a provocative stimulus. Depending on the setting and stimulus, it may occur in few people (eg, airplane travel without turbulence) or in nearly all people (eg, on a ship in rough seas or upon becoming weightless during space travel). […] Excessive stimulation of the vestibular apparatus by motion is the primary cause. This stimulation may be due to actual physical motion or perceived motion.

  https://www.merckmanuals.com/professional/injuries-poisoning/motion-sickness/motion-sickness

  Vestibular stimulation can result from angular motion (sensed by the semicircular canals) or linear acceleration or gravity (sensed by the otolithic organs [utricle and saccule]). […] The exact pathophysiology is undefined, but motion sickness occurs only when the 8th cranial nerve and cerebellar vestibular tracts are intact; those lacking a functional vestibulo-cochlear system are immune to motion sickness. […] The trigger may involve conflicting vestibular, visual, and proprioceptive inputs. […] Another possible trigger is a conflict in inputs between angular motion and linear acceleration or gravity, as can occur in a zero-gravity environment when turning (angular acceleration). […] In space adaptation syndrome (motion sickness during space travel), weightlessness (zero gravity) is an etiologic factor.

• #1 Understanding Motion Sickness

  https://www.uspharmacist.com/article/understanding-motion-sickness

  Humans detect motion through three sources of input to the nervous system. One is the vestibular system. Movement is detected in this system by stimulation of hair cells in the semicircular canals and in the maculae of the utricle and sacculus. Movement is registered in all three dimensions when endolymph moves through the semicircular canals or when small particles known as otoliths impact on hair cells. Through these mechanisms, the vestibular system facilitates spatial orientation, maintains balance, and helps stabilize vision. […] Motion sickness may occur when one of the sources of motion detection does not agree with the other two. In the majority of cases, visual input does not coincide with vestibular/proprioceptive input. The theory that encompasses and explains these concepts are known as the „neural mismatch” or „sensory conflict” theory. […] The hypothesized etiology of motion sickness explains why patients with a bilateral loss of the vestibular system are seemingly immune to the condition in normal circumstances. On the other hand, patients with vertigo, Meniere’s disease, or migraine are more prone to motion sickness.

• #1 Prevention and Treatment of Motion Sickness | AAFP

  https://www.aafp.org/pubs/afp/issues/2014/0701/p41.html

  Motion sickness is a common syndrome that occurs upon exposure to certain types of motion. It is thought to be caused by conflict between the vestibular, visual, and other proprioceptive systems. […] The pathogenesis of motion sickness is not clearly understood, but it is thought to be related to conflict between the vestibular, visual, and other proprioceptive systems. Rotary, vertical, and low-frequency motions produce more symptoms than linear, horizontal, and high-frequency motions. […] Nearly all persons will have symptoms in response to severe motion stimuli, and a history of motion sickness best predicts future symptoms. Females, children two to 15 years of age, and persons with conditions associated with nausea (e.g., early pregnancy, migraines, vestibular syndromes) report increased susceptibility.

• #1 VR Motion Sickness: Common Causes and Prevention Strategies – ArborXR

  https://arborxr.com/blog/vr-motion-sickness

  One of the significant obstacles to VR adoption is VR motion sickness. […] Research shows that 40-70% of VR users experience motion sickness, and about 25% start feeling the effects within just 15 minutes of use. […] VR motion sickness (or VR sickness) is a physical discomfort that occurs when there’s a conflict between what your eyes and ears are sensing and what they’re telling your brain during VR experiences. […] When your body remains stationary, but your eyes detect movement, your brain receives conflicting signals from both the visual and vestibular inputs, potentially leading to motion sickness. […] Some common symptoms of VR motion sickness include nausea, headaches, sweating, dizziness, fatigue, and a general feeling of imbalance. […] Some factors can exacerbate VR motion sickness or trigger it more quickly.

• #1 Motion Sickness: Background, Pathophysiology, Epidemiology

  https://emedicine.medscape.com/article/2060606-overview

  Motion sickness is an unpleasant condition that occurs when persons are subjected to motion or the perception of motion. It results in the common symptoms of nausea, nonvertiginous dizziness, and malaise. It is generally considered to be of physiological origin. Nearly all individuals experience it if exposed to enough motion stimuli. […] Motion sickness most likely occurs when the stimuli applied to these receptors appear to be in conflict. This apparent conflict causes more severe symptoms when the patient is passively moved at certain frequencies. It is much less common during active movements such as walking or swimming. […] Nearly all people experience motion sickness if given a strong enough motion stimuli. In many typical conditions, such as on cruise ships, the prevalence ranges from 3% to 60%, depending on the study.

• #1 Motion sickness: causes, prevention and management – The Pharmaceutical Journal

  https://pharmaceutical-journal.com/article/ld/motion-sickness-causes-prevention-and-management

  Motion sickness is caused by a conflict between the sensory input from the eyes, ears and muscles. […] The vestibular system, located in the inner ear, plays a critical role in maintaining balance and spatial orientation. […] When there is a discrepancy between the information received by the eyes and the inner ear, the brain interprets this as motion and triggers a response that can lead to nausea, vomiting and other symptoms. […] Motion sickness is typically managed in the community setting, meaning pharmacists can play an important role in identifying patients at risk and providing appropriate treatment and support to help manage symptoms. […] The incidence of motion sickness varies greatly, depending on the magnitude of the stimulus and the susceptibility of the individual. […] Patients with inner ear disorders, such as Ménière’s disease or those who have a history of migraines, are more susceptible to motion sickness.

• #1 What causes seasickness?

  https://oceanservice.noaa.gov/facts/seasickness.html

  Seasickness results from a conflict in the inner ear and the erratic motion of a vessel. […] Seasickness is a result of a conflict in the inner ear, where the human balance mechanism resides, and is caused by a vessel’s erratic motion on the water. […] Agitated by this perceptual incongruity, the brain responds with a cascade of stress-related hormones that can ultimately lead to nausea, vomiting, and vertigo. […] Additionally, an affected person’s symptoms can be magnified by the strong odors of things like diesel fumes and fish. […] Seasickness usually occurs in the first 12 to 24 hours after setting sail, and dissipates once the body acclimates to the ship’s motion. […] It’s rare for anyone to get or stay ill beyond the first couple of days at sea unless the vessel encounters really rough waves.

• #1 Motion sickness | Better Health Channel

  https://www.betterhealth.vic.gov.au/health/healthyliving/motion-sickness

  Motion sickness may occur in response to certain types of movement, whether it is the person or what they are looking at (for example, a movie screen) that is moving. […] In part, motion sickness is thought to take place when there is a mismatch between the information that the brain receives from the inner ear balance mechanism (vestibular system) and what the eyes see. […] A person who has experienced motion sickness in the past may have worse symptoms on future trips by expecting to feel sick. […] If a person is exposed to motion for an extended period (for example, during a long journey at sea) or has repeated exposures, their brain may adapt in time to the constant motion and they may no longer experience motion sickness. […] Motion sickness does not usually occur when movement is under a person’s control. […] Research suggests that ginger can help to ease the symptoms of motion sickness.

• #1 Motion sickness | MedLink Neurology

  https://www.medlink.com/articles/motion-sickness

  The pathogenesis of motion sickness remains incompletely understood, and several different pathogenetic models have been proposed. […] Sensory conflict is important in the development of motion sickness and, more specifically, a conflict between incoming sensory information from position and motion senses and what is expected from prior experience. […] Motion sickness results from a mismatch of signals from vestibular, visual, and proprioceptive receptors as integrated in the brainstem and cerebellum. […] Vestibular overstimulation as a basis for motion sickness was suggested by studies demonstrating that bilateral vestibular hypofunction prevented the development of motion sickness.

• #1 Motion sickness: an overview

  https://pmc.ncbi.nlm.nih.gov/articles/PMC7048153/

  Motion sickness is typically triggered by low-frequency vertical, lateral, angular, rotary motion, or virtual stimulator motion, to which an individual has not adapted. […] Sine qua non for developing motion sickness is when the brain receives conflicting information from different sensors about real body movements or virtual environment. […] The principal sensors are the eyes, the vestibular apparatus, and proprioceptive receptors. […] Motion sickness may also result from a spilling-over or irradiation from overexcited equilibratory centers to the vomiting center. […] The severity and duration of motion sickness depend on the degree of mismatch of motion-sensitive input signals and on the ability of the individual to adapt to the abnormal environment. […] Adaptation is presumed to occur if a susceptible individual learns to accept this conflicting sensory information without developing symptoms of motion sickness.

• #1 What causes motion sickness? | Popular Science

  Motion sickness can cause symptoms ranging from mild nausea to dizziness, sweating, and vomiting. […] The Centers for Disease Control and Prevention (CDC) state that motion sickness occurs when the movement your eyes see is different from the movement your inner ear senses. […] Motion sickness is not psychological. Experts suggest it occurs when what you see does not match what your inner ear is feeling. However, some experts suggest that psychology could play a role in motion sickness. The theory is that previous sickness may trigger memories and possibly worse responses. […] According to an older 2005 study, low serotonin levels in the brain may be linked to motion sickness and migraine. […] The supplements 5-Hydroxytryptophan (5-HTP) and magnesium may help raise serotonin. […] Doctors may recommend using vitamin B-6 (pyridoxine) to treat nausea and vomiting in pregnancy, among other conditions, like anxiety. Boosting your levels may also help with motion sickness, though more research is needed in this area.

  Motion sickness is caused by being in a moving vehicle. […] Cyber sickness is triggered by viewing moving content on digital devices. Both bring on nausea or discomfort. […] May be caused by a sensory mismatch or conflict between the signals the balance system sends to the brain. […] The most popular theory is that motion and cyber sickness are both caused by a sensory mismatch or conflict between the signals the balance system is sending to the brain. […] Similarly, if you are watching movement on an XR headset, your visual system detects movement, but your vestibular and proprioceptive systems do not. This can create a mismatch or conflict between the different parts of the brain’s balance system, similar to visually induced dizziness. […] Some XR simulations are more likely to cause cyber sickness than others because the amount of simulated movement is more extreme.

[…] It can also occur when the brain receives contradictory information from its motion sensors—the eyes, the semicircular canals, and the muscle sensors (nerve endings in muscles and joints that provide information about body position). […] The brain can also receive contradictory information if a person sees something moving excessively despite the person being still. […] Motion sickness may also occur in a moving car or other vehicle or on playground or amusement park rides. […] Some people are more susceptible to motion sickness than others. […] Genetic factors may also increase susceptibility to motion sickness.

  Vestibular stimulation can result from angular motion (sensed by the semicircular canals) or linear acceleration or gravity (sensed by the otolithic organs [utricle and saccule]). […] The exact pathophysiology is undefined, but motion sickness occurs only when the 8th cranial nerve and cerebellar vestibular tracts are intact; those lacking a functional vestibulo-cochlear system are immune to motion sickness. […] The trigger may involve conflicting vestibular, visual, and proprioceptive inputs. […] Another possible trigger is a conflict in inputs between angular motion and linear acceleration or gravity, as can occur in a zero-gravity environment when turning (angular acceleration). […] In space adaptation syndrome (motion sickness during space travel), weightlessness (zero gravity) is an etiologic factor.

  The pathogenesis of motion sickness remains incompletely understood, and several different pathogenetic models have been proposed. […] Sensory conflict is important in the development of motion sickness and, more specifically, a conflict between incoming sensory information from position and motion senses and what is expected from prior experience. […] Motion sickness results from a mismatch of signals from vestibular, visual, and proprioceptive receptors as integrated in the brainstem and cerebellum. […] Vestibular overstimulation as a basis for motion sickness was suggested by studies demonstrating that bilateral vestibular hypofunction prevented the development of motion sickness.

  Carsickness is a truly terrible sensation, but understanding a little bit about why it happens can help you figure out ways to prevent it. […] Nobody really knows what causes motion sickness, but it’s thought to be caused by a „sensory conflict,” says Maria Suurna, MD, an otolaryngologist at NewYork-Presbyterian and Weill Cornell Medicine. […] „It usually occurs due to exposure to physical or visual motion,” she says. […] In general, women and children tend to be more susceptible to motion sickness, Dr. Suurna says. […] Individuals who get migraines, or who have vestibular disorders that affect the inner ear, such as vertigo or Meniere’s disease, also might be more prone to motion sickness. […] „Any person with a normally functional vestibular system can get motion sickness when exposed to a certain type of motion,” she says. […] Rotary, vertical, and slow motions are more likely to cause motion sickness than linear or rapid motions, Dr. Suurna says. […] „By definition, motion sickness is precipitated by motion,” Dr. Suurna says.

  Motion sickness may occur in response to certain types of movement, whether it is the person or what they are looking at (for example, a movie screen) that is moving. […] In part, motion sickness is thought to take place when there is a mismatch between the information that the brain receives from the inner ear balance mechanism (vestibular system) and what the eyes see. […] A person who has experienced motion sickness in the past may have worse symptoms on future trips by expecting to feel sick. […] If a person is exposed to motion for an extended period (for example, during a long journey at sea) or has repeated exposures, their brain may adapt in time to the constant motion and they may no longer experience motion sickness. […] Motion sickness does not usually occur when movement is under a person’s control. […] Research suggests that ginger can help to ease the symptoms of motion sickness.

  Two small studies have reported an association between Chinese ethnicity and increased susceptibility to motion sickness. […] Several studies show that females report increased frequency and severity of symptoms and pregnant women are much more susceptible to motion sickness. […] Risk factors for motion sickness include age, sex, preexisting medical conditions, and concurrent medications. Other potential risk factors include pregnancy, menstruation, and taking hormone replacement therapy or oral contraceptives. Some prescriptions can worsen motion sickness-associated nausea. People with a history of migraines, vertigo, and vestibular disorders are more prone to motion sickness.

  https://medlineplus.gov/genetics/condition/motion-sickness/

  Motion sickness is a common condition characterized by a feeling of unwellness brought on by certain kinds of movement. […] The factors that contribute to motion sickness are not well understood, but susceptibility to the condition does seem to be partly genetic. […] When motion sickness occurs, it likely results from a mismatch in signals about movement coming from different parts of the body. […] Researchers believe it is this sensory conflict that triggers the symptoms of motion sickness. […] Common, complex conditions such as motion sickness are often polygenic, which means they involve variations in many genes. […] One study compared genetic variations in a large number of people with and without a susceptibility to motion sickness. […] These genes play a wide variety of roles in the body: some are involved in eye and ear development, and others in the formation of otoliths, which are tiny structures in the inner ear that are involved in sensing gravity and movement. […] Motion sickness does not have a clear pattern of inheritance, although it does tend to cluster in families.

  Motion sickness is annoying for some, debilitating for others, and strikes seemingly at random, with some people getting it their entire lives and others never experiencing it at all. […] Motion sickness affects people differently, and there’s no single reason why some people experience motion sickness more frequently than others, explained Saima Rajasingam, a lecturer in audiology at Anglia Ruskin University in a piece for The Conversation. […] For some of us, the urge to hurl on the highway may literally be in our DNA: there are a whopping 35 genetic variants associated with motion sickness, according to a 2015 study that analyzed data from 23andMe. […] Motion sickness can go hand-in-hand with other disorders it seems to be tightly linked to migraine susceptibility, for some reason, while inner ear problems such as Mnires disease also increase the likelihood of experiencing motion sickness, Rajasingam noted.

  Motion sickness also referred to as seasickness, carsickness or airsickness is caused when the brain receives mixed signals from our balance-sensing system which consists of our eyes, inner ear (semicircular canals) and sensory nerves. […] Mixed signals are received by the brain because your eyes cannot see the motion your body is feeling, or conversely, your body cannot feel the motion your eyes are seeing. […] Factors that can increase the chances for symptoms to appear include poor ventilation in a vehicle, the type of vehicle, fears or anxieties about traveling or the orientation in which a person is sitting or standing.

  There are other factors that can increase the chances of feeling motion sickness. Those include a history of migraines, hormonal changes (pregnant women, for example), genetics and even mindset. Often, those who expect to get sick are the ones who do. […] Preventing motion sickness is always the best option, when possible. […] For people with mild motion sickness (which typically means that it doesn’t interfere with the ability to function), it’s recommended to try the methods above instead of medications. […] Dramamine (dimenhydrinate) is a popular go-to remedy for motion sickness. […] Some people may experience the exact opposite effects, including insomnia, excitability and restlessness.

  The first, more common explanation is that it’s your body getting confused by a clash of sensory data. […] It’s when these sources of information are in apparent conflict that we may experience motion sickness. […] The problem comes when one of those inputs disagrees with the others. […] This is also why the less sensory mismatch we experience in a vehicle, the less likely we are to experience motion sickness, Rajasingam wrote. […] If the theory is correct, it’s enough to account for the discrepancy between the sexes, Stoffregen said. […] Why would this result in motion sickness? Once again, it comes down to a mismatch between what our bodies expect, and what they actually experience. […] In fact, as far as the reptile brain is concerned, there is only one likely answer: poison.

  Some people feel very sick while travelling in an airplane, boat, train, or car. […] When you are in a vehicle that moves continuously with relatively slow and prolonged motion, the organ of balance in your inner ear may be affected, causing motion sickness. […] In motion sickness, a discrepancy exists between the motion that is expected to occur and the actual motion sensed by the organ of balance in the inner ear. […] Generally, symptoms disappear once the brain adapts to the new pattern of motion. […] 2 neurotransmitters (chemicals that relay messages to cells within the brain) acetylcholine and dopamine are thought to play an important role in causing motion sickness.

  Motion sickness happens when the reality of movement and the perception of movement are not the same. For example, you are sitting still in a car, but your vestibular system senses head movement, which is the movement of the car. This results in you feeling unwell. […] The exact neurobiological reason that some people experience motion sickness is not known. However, it is thought to be the result of your body feeling unbalanced in some type of moving vehicle, causing confusion in your senses. […] Some common causes of motion sickness include: car rides, train rides, air travel, amusement rides, video games or virtual reality. […] Specific circumstances that may cause motion sickness include: not having enough air circulation while in the car, reading in the car, experiencing turbulence while on a plane, feeling the rocking of a boat, sitting in the backseat of a car and being unable to see the horizon.

  Motion sickness is caused by being in a moving vehicle. […] Cyber sickness is triggered by viewing moving content on digital devices. Both bring on nausea or discomfort. […] May be caused by a sensory mismatch or conflict between the signals the balance system sends to the brain. […] The most popular theory is that motion and cyber sickness are both caused by a sensory mismatch or conflict between the signals the balance system is sending to the brain. […] Similarly, if you are watching movement on an XR headset, your visual system detects movement, but your vestibular and proprioceptive systems do not. This can create a mismatch or conflict between the different parts of the brain’s balance system, similar to visually induced dizziness. […] Some XR simulations are more likely to cause cyber sickness than others because the amount of simulated movement is more extreme.

• #2 What causes motion sickness?

  https://www.mymed.com/diseases-conditions/motion-sickness/what-causes-motion-sickness

  Simply put, motion sickness (carsickness, seasickness, air and simulation sickness) is a result of mixed signals that are sent to the sufferers brain by the inner ear (particularly the semi-circular canals within it) and the eyes. […] When active movements are absent, the brains estimation of motion will be primarily based on the vestibular, somatosensory and visual information it receives. If these three primary sensory signals are not in harmony, this will generate conflicting sensory cues within the brain and it is thought that this conflict is what results in the symptoms associated with motion sickness. […] Motion sickness may also be induced when a persons visual system senses movement, but the vestibular system senses a different motion, as is often the result when playing virtual reality (VR) games.

  https://familydoctor.org/condition/motion-sickness/

  Motion sickness is a sick feeling triggered by movement. It occurs in cars, buses, trains, planes, or boats. It can occur on amusement rides or virtual reality experiences. Seeing the movement of others or things can trigger it. This condition is not life-threatening, however, it can make traveling unpleasant. […] Motion sickness is common in older people, pregnant women, and children between the ages of 5 and 12. Also, it’s common in people who have migraine headaches. It may be genetic. Once the motion stops, you’ll gradually feel better. In rare cases, the condition is triggered by a problem with your inner ear. This could be due to fluid buildup or an ear infection. Parkinson’s disease is another cause of the condition. […] Motion sickness is an imbalance between what you see and what you feel. In the car, the car is moving forward. However, your body is standing still. This imbalance is what causes you to feel sick.
