Title: What causes motion sickness?
Post by: sgroclkc on 12/10/2006 04:07:09
On the one hand motion sickness experts agreed on the way in the  carsickness, seasickness and airsickness gets sick or motion sickness is caused by motion or rotation or visual stimuli http://www.postgradmed.com/issues/1999/10_01_99/gahlinger.htm (http://www.postgradmed.com/issues/1999/10_01_99/gahlinger.htm), but on the other hand  motion sickness experts agreed on the way in the really cause of the motion sickness is not motion, spinning,the precise etiology of motion remains a mystery.http://www.sciencemaster.com/jump/space/motion.php (http://www.sciencemaster.com/jump/space/motion.php) and http://nasaexplores.com/show2_articlea.php?id=01-040 (http://nasaexplores.com/show2_articlea.php?id=01-040)   Because this would not explain the person who are susceptible to carsickness do not suffer carsickness ,when the person rides  train,truck, motorcycle and tractor. Because, of the infrasonic sound or the noise of low frequency is extremely small. And spinning around motion sickness differs from carsickness, seasickness and airsickness in a symptoms.For instance, carsickness, seasickness and airsickness all has a symptom of drowsiness,spinning around motion sickness has not a symptom of drowsiness,spinning around  motion sickness has a symptom of spinning around feeling ,carsickness, seasickness and airsickness all has not a symptom of spinning around feeling . This Self-Contradictory Statements is really unprecedented in human scientific history But in reality all these carsickness, seasickness and airsickness gets sick or motion sickness is caused by infrasonic sound or the noise of low frequency.  Of instance, (1) this would explain the person who are susceptible to carsickness do not suffer carsickness ,when the person rides  train,truck, motorcycle and tractor. Because, of the infrasonic sound or the noise of low frequency is extremely small.  (2)  There was a highest incidence of seasickness in the speedboat,the speedboat  noise is biggest of among all sorts of ships. Proved that seasickness is caused by noise (3)  There was a highest incidence of airsickness in the Jet plane,the Jet plane noise is biggest of among all sorts of Planes. Proved that airsickness is caused by noise (4) Space motion sickness is caused by the infrasonic or the noise of low frequency,too.Of instance,the power of the engine of Mercury and Gemini is small that the infrasonic or noise of Mercury and Gemini is small.So,Mercury and Gemini space flight astronauts did not experience space motion sickness.astronauts of Mercury and Gemini floating free in space,too. http://www.sciencemaster.com/jump/space/motion.php (http://www.sciencemaster.com/jump/space/motion.php)
 But it was most important to scientists had confirmed motion sickness is caused by infrasonic sound or the noise of low frequency.
For example,Surf pounds the shore, producing shocks of 16 cycles per second, just short of the true infrasound range. Ocean waves, which pound the atmosphere across huge ocean areas, produce an acoustic energy with a mean pitch of 16 cycles per second. The phenomenon of the "barisal guns, fog guns, lake guns" form a well documented bibliography of anomalous acoustic phenomena. These "booming" anomalous tonal phenomena are not isolated to one area or nation. Every nation has accounts of these sea-related mystery sounds. Some regions call them "bay detonations", since they come as abruptly explosive intonations from certain bay areas.
Some of these tones manifest their shocking tones at haphazard intervals. But there are those water-related booms, which are periodic, residents near these sites being accustomed to their mysterious occurrence. The strange "explosive" sounds come at certain times of the day, at certain times of the month, and at certain times of the year. There are certain other related anomalous natural tones, which ring, hoot, and buzz. Some have been likened to organ tones, tuba blasts, and the deep intonings of very large bells. Bay sizes, wave sizes, and geologic compositions of bays and shores have been woven into complex mechanistic attempts at explaining how these mystery sounds are being generated in certain environments.
The detonation may be caused by a sudden "slapping" of bay water by a singular wave having the "right" breadth and momentum, matching the natural resonant pitch of a bay. The underlying bay rock matrix may resound in the manner of a bell, gong, or cymbal. The geological composition of the bay plays the greater part of the effect, sudden winds or water surges knocking the natural "sounding board". These natural bay tones have great infrasonic content.
The infrasonic outputs of the mystery tones are significant. Each of these phenomena produces a range of very low pitch tones. These booming sounds have rattled windows and rocked some small towns. Animals are startled by their inaudible precursors, and humans are often dizzied after their manifestation for hours. In several areas, people are hospitalized by the "boom" related illnesses.
Waterfalls are notorious generators of infrasound. Numerous susceptible visitors at Niagara experience a peculiar nausea, which is not associated with the normal fear of heights. Thundering cataracts produce strong infrasonic shocks to which mile exposure stimulates the common malady. Lake ice and glacial ice produce deep booming sounds which ring for hours, behaving as large tympanic surfaces. The thunderous sounds associated with these occurrences produces infrasound of pitch related to ice surface mass, breadth, and length alone. Antarctic research experienced nausea in relation to ice related sounds.
Tidal waves and other sudden variations of water surfaces produce large magnitude "seiche" waves. These have been sighted by ocean going ships, where oceanic surfaces have drastically changed elevation in an incredibly short time. Ships "drop" into such huge ocean troughs and rise again after the wave passes. In dropping, some have crashed to the very rock bottom of their bays, only to be lifted in pieces when the wave resurged. Film footage of the great and horrid Alaskan Earthquake (1964) reveals this devastating sea "drop-out".
Upon such lethal seiche tides, even in the fortunate absence of earthquakes, comes nausea and other coastal related illnesses. Large intensity infrasonic sea shocks have their powerful effect on the overlying atmosphere of their regions. These infrasonic shock waves travel for long distances. Certain bays are known for the high incidence of such illnesses, the result of resonant bay water "heavings" which occur daily. Their sickening effects are seemingly "stored up" in physiology, lasting for hours. While these phenomena proceed from deep in the heart of earth, and on its surface, there are phenomena, which generate infrasonic sources ... from space.
http://www.hbci.com/~wenonah/history/gavreau.htm (http://www.hbci.com/~wenonah/history/gavreau.htm)
Low intensity infrasound from autocar engines has been well recognised to induce car sickness (30)(98) - a mild serotonergic-vestibular disturbance involving nausea, giddiness, headache.http://www.markpurdey.com/science_the_origins_of_bse_7.htm (http://www.markpurdey.com/science_the_origins_of_bse_7.htm)
 
Moreover this theory about motion sickness is caused by all kinds of acceleration of different directions and size or Coriolis acceleration (,reference: http://www.remarkablemedicine.com/Clinical/clinicaluses/otherdisorders/motion.html),Overthrow (http://www.remarkablemedicine.com/Clinical/clinicaluses/otherdisorders/motion.html),Overthrow) Newtonís second law of motion.Because,Newtonís second law of motion says anly by calculate a man or an object is influenced by size of the resultant force can know a man or an object is influenced by the size of the in reality acceleration.of instance, the astronaut is affected by the Gravitation acceleration as well as the centrifugal force acceleration in space,But the in reality is affected by acceleration equal for zero.
So,this idea not only was a fraud but it was maximum jest in human scientific history.
 Motion sickness experts knew this, they kept quiet up to now
  And they knew rendered violently nauseous noise of an airplane,they calling this motion sickness a ďconditioned reflex,"Their statement rather absurd.

As the human senses of hearing and motion detection both use the inner ear and similar sensors and low frequency motions will produce low frequency sounds it is not supprising that low frequency sound and motion sickness are linked.

I do not normally reject hypotheses on the basis of personal experience, but in this case I shall make an exception.

As a child and teenager I routinely travelled by ferry from my island home to the mainland. When the weather was calm, sitting in the ferry, subject to the noise of its engines, I would reach the other side feeling perfectly well.
When the weather was rough, sitting in the same location, subject to the same noise, I would reach the other side feeling decidely sea sick.

As a child and an adult, sitting in a car, carefully looking ahead and anticipating the movements of the car, I could travel hundreds of miles with no ill effects. In the same car, attempting to read a book, or a map, I would be car sick within two minutes.

Travel sickness is related to a mismatch between what our balance organs tell us is happening and what our eyes tell us is happening. Before we developed forms of transport such a mismatch indicated that we were hallucinating. The probable cause was poisoned foodstuff. The solution was to get rid of the poison by vomiting. That is the simple explanation for motion sickness and it is not a swindle.

A rocking boat or a bumpy airplane do lead to the motion sickness is coincidence,the greater a rocking boat or a bumpy airplane ,the greater the infrasonic of boat or airplane
A symptom of rotation motion sickness is different distinct from carsickness, seasickness and airsickness,so it is certain rotation motion sicknesshave nothing to do with carsickness, seasickness and airsickness

sgroclkc, I'm afraid I'm having trouble with your english but I understand you to be suggesting that motion sickness is caused not by motion but by infrasonic "noise" from the engine. If this is indeed your suggestion, how do you account for the fact that sea sickness dates back to long before the invention of engines?

Space sickness is caused by weightlessness (absence of gravity).

Carsickness, seasickness and airsickness are caused by altered gravity.

Travelling on the ship on the rough sea we are constantly exposed to the some extent of lift off (in time when wave lifting ship) and to the some extent of free fall (for the time when wave causing that ship going down)

In moment of lift off, the human body is exposed to gravity force bigger than 1G and in moment of free fall is exposed to strength of gravity forces less than 1G.
 
Frequency of the change of the strength of the gravity determines extent of sickness (simplify theory).

Travelling on the ship on the rough sea is like travelling on moving platform (ship constantly going up and down and swaying from one side to another).
 
Travelling on the ship on quiet sea is like standing, seating or walking on the solid ground.
 
Body is exposed by altered gravity on similar way by travelling with the car and by airplane.

Train sickness it is unknown, because train travel on more straight direction and seldom steering up the hill and down a hill.
Only in the time of speeding, usually when train leaving station and in the time of slowing usually when train arriving in station passengers are exposed to small extent of altered gravity.

It shows that motion does not cause sea, car or airplane sickness but frequency of the alteration of the gravity force on the humanís body.

"Motion sickness" is not appropriate name to describe health condition caused by altered gravity. Appropriate name will be ďaltered gravity sicknessĒ.
Understandings importance of the pull of gravity for humans and any living organism will enable to understand prevent and cure many nowadays illnesses and diseases.

Infrasonic is caused by closed automobile compartment or cabin in vibration.For instance,the truck, motorcycle and tractor has not closed compartment,infrasonic is very little that it can not carsickness.

You are right Rosy. I shouldnít write that train sickness is unknown but less common.
 
I think that train sickness is less common than space, see, and airplane and car sickness.

Train sickness in most case is not caused by altered gravity but by (uncommon or unusual) visual stimulation.
I think that air and see sickness is caused by altered gravity and car sickness is caused by altered gravity and uncommon visual stimulation combine (watching through side window).
What is interesting to me is that see, airplane, car and train sickness affects mainly (if not only) passengers. It shows that mentally factor is important as well.
I think that explanation is, that passengers are passively affected by altered gravity or uncommon visual or sound stimulation and operators of the transport devices are in more active state of mind in time when they are affected by altered gravity, uncommon visual or sounds stimulation.

I think there are many different aspects of transport sickness, and different people are subject to different aspects of them.

To date, I have never been sea sick in my life (I did feel queasy on one journey, but that was more from the smell of vomit of the other passengers rather than my own motion sickness).  In general, the rougher the sea, the more I enjoy it (together with just a hint of shadenfreuden  - not very nice of me, I know).

I used to be car sick when I was less experienced in cars (my first time on a boat was when I was about 4 months old, and that was for 32 days, so it may have inoculated me against sea sickness).

One related aspect of this is that many years ago I started taking flying lessons, and on one occasion my flying instructor took me just along the upper boundary of the clouds, while we were skimming in and out of the clouds (flying on instruments), and I think he thought that might disorientate me.  I was not at all disorientated, and I suspect I just have a knack of disassociating my visual senses from my other senses (it probably also relates to the fact that I cannot have a strong emotional response to visual stimuli).  This may well be something that protects me against motion sickness.

On the other hand, I do get drowsy (but not sick) from infrasound.

As for train sickness, it is unusual, but the train under the channel tunnel does seem to effect some people (my mother is one of them - she is effected more by that than by sea sickness).

Do deaf people get seasick?
If so then I think we can kiss goodbye to any idea that it's produced by infrasound (at least unless you can find another organ to sense the infrasound).
This page
http://www.royaldeaf.org.uk/page.php?id=100303
sugests that deaf peopel do suffer from seasickness.

I don't get seasick (or airsick or whatever) but I do get uncomfortable when there are high levels of low frequency sound- the ventilation system where I work sometimes has this effect.

I think infrasound can be detected away from the ear (in any case, it will depend on the nature of deafness, since I doubt it would effectively be channelled by the outer ear).

Don't forget that Beethoven could detect infrasound despite the deafness of his later years, and if you stand in a church with an organ playing its deepest notes, you will feel those notes right through your body, not merely through your ears (these notes do not normally record well on recordings of organ music, and that is the difference between listening to organ music live, and listening to a recording of it).

This is not to suggest that infrasound causes sea sickness (I never suggested that, only that it can induce drowsiness, and this has sometimes been claimed to be a factor in drivers falling asleep on long journeys).

Carsickness is caused by the motor which produces a special and rumbling low-frequency noise. Train, metro, truck, motorcycle and tractor which produce no such noise will cause no carsickness.

Motion sickness occurs without an engine.
Standard laboratory test to induce motion sickness is a standard office chair, subject blindfolded, chair rotated, subject told to put head back to side etc. Very rarely does this fail to bring on motion sickness. No motor.

Train, metro, truck, motorcycle and tractor which produce no such noise will cause no carsickness.
No so. I know people who suffer motion sickness on all of these.

If you have a theory of vibration induced sickness you need to clasify it as a separate theory from motion sickness.

For really good, violent and repetitive motion sickness, try glider aerobatics. No engine, and the better the glider, the less vibration at any frequency (noise and vibration = lost energy, and we don't like that!). It works best if you are in the front seat and the pilot  is behind you, so you have no visual cue as to what happens next. Those of a nauseous disposition can throw up when entering a very gentle turn, and even hardened powered aviators have a problem hanging on to their breakfast during a glider display sequence flown by the guy in the back seat.

Flying dual cross-country needs regular swaps between navigation and handling duties even in a side-by-side glider to avoid mal-d'air. Taking control gives you the cues you need to avoid eye/ear/brain confusion, which is why car drivers don't get sick when their passengers do.

The symptoms caused respectively by gyrating and carsickness are quite different. Gyrating movements will cause dizziness, while carsickness usually causes nausea or sleepiness. This is why authors of many scholar articles only state that gyrating symptoms are associated to carsickness, but the reasons behind carsickness are still unknown. Only unreliable knowledge popularizing articles say that the reason of carsickness is gyrating movements. This is not true. Actually, gyrating movements are not related to carsickness, which is actually caused by a special low-frequency noise. Only this kind of noise can cause exactly the same symptoms of carsickness. For example, even without staying on the airplane, the noise of airplane engine can also cause symptoms of carsickness. Experts of carsickness around the world all know that only noise can cause exactly the same symptoms of carsickness, but they fraud people by saying that this phenomenon is only a psychological reaction!

The stuff in my sickbags depends on what the victim had for breakfast, not whether the aircraft has an engine.

Part of the problem with instrument flying, yacht navigation or rear-seat car sickness is the inability of the semicircular canals to distinguish between linear acceleration and circular motion.    You can induce carsickness by stop-start driving on a straight road, and airsickness on scheduled flights or glider "dolphining"  is caused by sudden changes of pitch attitude, not turning.   

If it's all due to infrasound, why don't pilots and drivers suffer the same symptoms as their passengers? It isn't a matter of aptitude or experience - hardened drivers often throw up when navigating in rallies, and the most experienced pilots still need to swap duties with each other to avoid becoming incapacitated under competition conditions. 

The one time I had an entirely incapacitated crew was on a fairly large yacht, reaching  into an opposing tide. For about two hours, we made no progress over the ground but just pitched and rolled at random intervals in almost total silence, broken only by groans and the sound of eight experienced sailors donating their stomach contents to the sea. The only relief was to do something: taking the helm in turn, or tweaking the sheets, though the latter was completely unncessary as we had the boat pretty well trimmed anyway, but the feeling of being a bit in control or able to anticipate the next roll was very calming.

Early on in my sailing days I noticed an uncharacteristic craving for ginger biscuits. I later discovered that Chinese sailors have always used ginger as a prophylactic against seasickness, and it seems to work as well as modern molecules without inducing drowsiness. Any explanation would be welcome!

It  was  firstly  proposed  by  a  Chinese  physicist  of  acoustics  that  motion  sickness  was  caused  by  infrasound.  After  reflecting  on  this  over  and  over  again  for  years,  I  think  this  view  is  wrong.  In  my  opinion,  motion  sickness  is  supposed  to  result  from  booming  low-frequency  noise.  For  instance,  it  is  beyond  doubt  that  extremely  loud  booming  low-frequency  noise  is  always  heard  inside  vehicles  which  easily  bring  about  motion  sickness.  Inside  vehicles  without  such  noise,  motion  sickness  isnít  caused  at  all.  In  spite  of  loud  noise  of  tractors,  people  donít  feel  sick  inside  them  because  there  is  no  booming  low-frequency  noise.  The  key  reason  consists  in  that  the  noise  of  tractors  doesnít  distract  people  because  they  donít  impact  their  verbal  communications  due  to  differences  between  frequency  of  the  noise  and  peopleís  voices. 
     Some  other  evidences  can  prove  that  motion  sickness  just  arises  from  the  aforementioned  noise:  People  with  good  hearing  easily  suffer  from  motion  sickness,  while  the  deaf  and  dumb  who  canít  hear  donít  feel  sick  inside  vehicles  at  all.  The  noise  is  louder  inside  fairly  closed  vehicles,  so  people  easily  get  sick  in  highly  closed  luxury  buses  and  cars.  The  noise  is  so  penetrating  that  motion  sickness  canít  be  avoided  either  even  if  ears  are  covered  with  something.

Early on in my sailing days I noticed an uncharacteristic craving for ginger biscuits. I later discovered that Chinese sailors have always used ginger as a prophylactic against seasickness, and it seems to work as well as modern molecules without inducing drowsiness. Any explanation would be welcome!
Lots of sailors swear by ginger and interestingly NHS site recommends it for morning sickness. I've never found any firm evidence, some studies say it works others not. It's often discussed on sailing forums but seems to depend on the individual whether it works. It's a long time since I trawled the research, might have another look, if I come across anything interesting I'll let you know.
One thing most sailors will agree on is that getting your head down on a centre bunk really helps. Obviously there is less motion in the centre area and closing eyes removes the conflict , but I wonder whether the inner ear is more sensitive when head is upright than when prone.

Some  other  evidences  can  prove  that  motion  sickness  just  arises  from  the  aforementioned  noise:  People  with  good  hearing  easily  suffer  from  motion  sickness,  while  the  deaf  and  dumb  who  canít  hear  donít  feel  sick  inside  vehicles  at  all. 

Worth considering whether you are talking about profoundly deaf people or folk with normal neurology and anatomy but age- or noise-related deafness. Even age or disease can reduce one's propensity to mal de mer as the fluid in  the semicircular canals thickens. A friend of mine suffers from nausea with almost any change in position, due to deposition of calcite crystals in the canals - a fairly common and inherited condition -  which send multiple attitude signals to the brain.

Infrasound can indeed induce nausea, but the mechanism is thought to be different - either resonance in the chest cavity or disturbance of gut peristalsis. The human ear does not respond to sounds below about 15 Hz, which is why they are callled infrasound.

Wow!
You came back after all this time, and ignored the evidence.
The evidence show that people who gets sick in a car usually can travel in trains or motorcycles without any discomfort at all.

Why?

Low intensity infrasound from autocar engines has been well recognised to induce car sickness - a mild serotonergic-vestibular disturbance involving nausea, giddiness, headache.

Why?


Because trains don't accelerate, decelerate and change direction as often or as violently as cars, and you turn a motorbike by leaning into the turn so you don't experience anomalous g-force and the passenger has a visual cue to the turn.  Plus the motorbike passenger is busy all the time, holding on and following the driver's lean, and can see where he is going.

In addition to the post above which I agree with.
I know 2 pillion passengers who had to give up because of motion sickness. I also know people who can travel in a train if facing forwards, but not if facing backwards.
The only time I have felt motion sickness in a car was in the back of a taxi on one of the drop down rear facing seats.

Roaring low-frequency noise instead of infrasound causes carsickness. Symptoms of carsickness get stronger when vehicles bump or shake more frequently, which is just a coincidence. It is just because low-frequency noise gets louder when bumping and shaking gets more serious. Without such low-frequency noise, people will not feel carsick no matter how hard the car bumps or shakes. For example, people get carsick on trains or subways running at the same speed when hearing low-frequency noise. Without such noise on trains or subways, carsickness can be avoided. It fully proves that low-frequency noise is the only reason that causes carsickness.   
     By far, there has been no effective methods or progress to solve carsickness, as a result of false and deceptive carsickness theories brought up by authorities and experts. If people can acknowledge the view that low-frequency noise leads to carsickness, then they can immediately and completely get rid of carsickness, plane-sickness, or seasickness (part of seasickness is caused by low-frequency noise from storm at sea, which is unavoidable natural disaster) caused by low-frequency noise from the engine as long as all transportation tools stop generating such noises. It is readily feasible in terms of technology. Thus, if consumers purchase cars with loud noise, which is severe quality issue, they should immediately claim compensation from car manufacturers and require them to recall for remodeling until it stops making such noises in operation. Therefore, such noises will not only cause painful carsickness, but lead to hearing loss under long stimulation from such noises.

I can tell how I think it it works in my case. I have sea sickness that occurs after about half an hour, and also if i am onboard  a  helicopter for more than 3-4 hours.
In the past I have experienced a period of chronic fatigue that made me even more sensitive to motion. I have onserve that if I played on a computer a game that I wasn't used to the motiom mechanics, I would get that sickness quite quickly. A 3d video for example can make almost anyone feel sick. Therefore, the sickness must be related to the brain. If the motion you experience doesn't match what the brains expect to happen the brain needs to learn the new mechanics. If the flow information that comes is high, I suppose that some hormones are activated that enables the brain to cope with the high demand. However, if the hormone production cannot keep upwith  the requirements the hormones levels go down and the brain cannot handle the situation well and you get sick. Now that I have passed the chronical fatigue phase, I can cope much better with things like that. The chronical fatigue was confirmed by symptoms like poor sleep during night and sleepiness during the day, slow recovery after exercise, poor digestion, joint pain, poor immunity (frequent colds),etc.
As a conclusion, it should be related to the hormone production capacity and overal endocrine strengthness.
Also if you have a problem with the inner ear for example it can cause random inputs that confuse the brain.

Your  question  has  already  been  thought  about  a  lot,  if  seasickness  is  caused  by  shaking,  then  why  until  now  there  is  no  exercise  specialist  says  that  the  cause  of  motion  sickness  have  been  found  in  the  world  is  shaking?  But  why  do  the  real  recognized  reasons  of  motion  sickness  not  be  found?  I  always  take  the  boat  with  a  big  quake,  but  I  never  have  the  feeling  of  seasickness  and  never  see  the  people  around  me  have  the  slightest  seasick  symptom.The  old  crew  on  the  sea  almost  all  the  year  round  has  said  that  the  more  shaking  the  boat  is,  the  less  possibility  to  get  seasick.  Thus  it  can  be  seen  that  seasickness  has  nothing  to  do  with  shaking  and  sports.  Ancient  Chinese  and  ancient  Greece  had  a  view  that  the  boat  sailing  on  the  sea  would  cause  nausea  when  it  met  sandstorms(Because  carsickness  and  seasickness  only  have  the  signs  of  nausea  and  vomiting  with  no  vertigo  syndromes.  Only  rotation  will  have  symptoms  of  dizziness  and  seasickness.  Carsickness  and  seasickness  with  the  symptom  of  dizziness  are  fabricated  by  experts  to  confuse  the  symptom  of  carsickness  and  seasickness  with  that  of  dizzy.)  There  is  no  saying  that  ancient  people  would  feel  nausea  when  they  took  the  shaking  carriages  with  large  turbulence,  this  is  because  the  shaking  of  ancient  carriage  is  very  violent,  but  there  is  no  engine  producing  low-frequency  noise,  that  won't  cause  carsickness.  Different  reasons  will  inevitably  lead  to  different  results.  If  the  shaking  of  boat  can  really  cause  seasickness,  so  this  kind  of  seasick  symptom  caused  by  shaking  and  seasickness  caused  by  low-frequency  noise  will  certainly  be  different,  which  can  just  prove  seasickness  has  two  reasons,  low-frequency  noise  and  shaking  that  will  cause  relevant  two  different  seasickness.  As  I  discovered  in  1992,  the  nightmare  was  caused  by  two  palpitations,  racing  heart  and  slow  beating,  which  would  correspondingly  cause  being  pursued,  attacked  and  people  flying  up  and  down.  So  seasickness  has  the  same  story  with  these  two  common  nightmares.

Different causes will generate different results. Motion sickness is caused by in-situ rotating motion, 3D visual movement, and low-frequency noise three main causes, with completely different symptoms. The corresponding in-situ rotating motions may cause symptoms of dizziness, 3D visual movement may cause mild dizziness, and low-frequency noise may cause nausea, vomiting, and drowsiness. That is to say rumbling low frequency noise may cause carsickness, seasickness, and airsickness.

Scientific theories can also be testable and make falsifiable predictions.For instance, a view holds, Carsickness is caused by special low-frequency rumbling noises. Hence people with acute hearing become sick easily, while deaf people who canít hear any noise do not get carsickness. Also, even when people are standing near an airplane rather than riding on the car, the stimuli from the low-frequency rumbling of the airplaneís motor still triggers intense airsickness.We not get carsickness can't hear the low dull rumbling sounds from the aircraft, trains, subways, trucks, motorcycles, tractors.People get carsickness on trains or subways running at the same speed when hearing low-frequency noise. If any evidence can be cited to prove that deaf people also get carsickness yet can avoid it by not riding any vehicles, this opinion can be invalidated. In reality, however, pseudoscience cannot be falsifiable predictions. For instance, a pseudoscience opinion that carsickness is caused by 3D optokinetic stimulation cannot be overturned by the fact that the blind still gets carsicknes

Scientific theories can be confirmed. introducing several causes of a disease, a scientific researcher will further explain different consequences resulting from each cause to prove his opinion.For example, nightmares are caused by the symptoms of tachycardia. bradycardia or premature beat.and the most awful temporal brain ischemia cardiovascular diseases, which are also common in healthy people during the day. Correspondingly, dream of being chased or dream of attacked;dream of flying in the air or dream of falling down and the most awful sleep paralysis these three kinds of nightmares with different clinical manifestations will be caused.Motion sickness is caused by axis rotation,3D visually induced and low-frequency noise three main causes, with completely different symptoms. The corresponding axis rotation may cause symptoms of the most awful dizziness, 3D visually induced may cause mild dizziness, and low-frequency noise may cause nausea, vomiting, and drowsiness. That is to say rumbling low frequency noise may cause carsickness, seasickness, and airsickness.
On the contrary, pseudoscience is confined to introducing the causes of nightmares and motion sickness, without further explaining each causes different clinical manifestations. Otherwise, the lie will be self-defeating.

There are over 3 different types of motion sickness , each with their own causes, symptoms, and treatments.For example:
This type of terrestrial motion sickness is particularly prevalent when susceptible people are watching films presented on very large screens such as IMAX, but may also occur in regular format theaters or even when watching TV or playing games. For the sake of novelty, IMAX and other panoramic type theaters often show dramatic motions such as flying over a landscape or riding a roller coaster. This type of motion sickness can be prevented by closing one's eyes during such scenes.However, this method is not effective for motion sickness caused by spinning motion and low frequency noise.

Funnily enough I might agree that there are different mechanisms for inducing motion sickness, but in every case they involve a difference between two perceptions of motion.

The "cinema" effect is particularly interesting. Many people experience a "mechanical" sensation of falling when shown an immersive video from a plane flying over a cliff edge, a helicopter climbing  up a waterfall, or a rollercoaster. The optical and baroreceptor inputs are at variance and you can feel your abdominal muscles tighten as if for a vomit.

I think we can dismiss the centrifuge experiments, however. Flying in a constant tight turn or being whirled around in a centrifuge doesn't normally induce motion sickness if you are looking forward - the landscape is just moving at a constant speed but an unusual angle, and you just feel heavier. If you are flying in cloud or fog it's very difficult to tell whether you are turning at all unless you look at your gyro instruments. However looking directly downward at the landscape can be disturbing as the perceived view slightly forward of vertical is different from that slightly backward - it's easy to turn the wrong way to recover from a spin!

That said, frequent changes of attitude and bank angle does induce nausea unless you are prepared for it: vigorous flying in a two-seat glider is very uncomfortable for the navigator, so it's advisable to swap duties every couple of minutes, and sea sickness can often be quelled by taking the tiller: being able to anticipate or control the motion has a remarkably calming effect on the digestive system.

I think we can dismiss most forms of deafness as protective against motion sickness since the cochlea is quite separate from the balance organs, but serious damage to the connecting nerves might well result in an insensitivity to motion.

The first case of space motion sickness is now thought to be the Soviet cosmonaut Gherman Titov, in August 1961 onboard Vostok 2, who reported dizziness, nausea, and vomitingThe first severe cases were in early Apollo flights; Frank Borman on Apollo 8 and Rusty Schweickart on Apollo 9. Both experienced identifiable and quite unpleasant symptomsóin the latter case causing the mission plan to be modified.
It's not a coincidence that the astronauts of the United States and the Soviet Union suffered from motion sickness during their second space flight. This is because the engine power of the first space capsule that the astronauts of the two countries took was low, and the low-frequency noise produced was also low. Therefore, the astronauts of the two countries did not suffer from motion sickness.
During the second space flight, the engine power of the two countries' space capsule increased, and the corresponding low-frequency noise generated by the engine also increased. As a result, the astronauts of both countries suffered from motion sickness during the second space flight.

You search Google with the keyword "Deaf people get seasick"
The unanimous conclusion is that deaf people do not get carsick or seasick.

And you get referred back to this thread.

This thread points out lots of clear reasons why you are wrong.

There's this
https://www.washingtonpost.com/news/retropolis/wp/2017/05/05/i-wanted-to-serve-these-deaf-men-helped-nasa-understand-motion-sickness-in-space/

which shows that people with knackered semi-circular canals don't get motion sick- because that's where the problem is caused.
But people with other forms of deafness (who clearly can't hear infrasound) do get motion sickness.

You can tell from the responses from deaf people who get travel sick , for example, here

[/quote]Anecdotal evidence is a factual claim relying only on personal observation, collected in a casual or non-systematic manner. The term is sometimes used in a legal context to describe certain kinds of testimony which are uncorroborated by objective, independent evidence such as notarized documentation, photographs, audio-visual recordings, etc.

When used in advertising or promotion of a product, service, or idea, anecdotal reports are often called a testimonial, which are highly regulated[1] in some jurisdictions.

When compared to other types of evidence, anecdotal evidence is generally regarded as limited in value due to a number of potential weaknesses, but may be considered within the scope of scientific method as some anecdotal evidence can be both empirical and verifiable, e.g. in the use of case studies in medicine. Other anecdotal evidence, however, does not qualify as scientific evidence, because its nature prevents it from being investigated by the scientific method. Where only one or a few anecdotes are presented, there is a larger chance that they may be unreliable due to cherry-picked or otherwise non-representative samples of typical cases.[2][3] Similarly, psychologists have found that due to cognitive bias people are more likely to remember notable or unusual examples rather than typical examples.[4] Thus, even when accurate, anecdotal evidence is not necessarily representative of a typical experience. Accurate determination of whether an anecdote is typical requires statistical evidence.[5] Misuse of anecdotal evidence is an informal fallacy[6] and is sometimes referred to as the "person who" fallacy ("I know a person who..."; "I know of a case where..." etc.) which places undue weight on experiences of close peers which may not be typical.https://en.m.wikipedia.org/wiki/Anecdotal_evidence

Did you just call those deaf people liars?
(It's hardly credible that they are mistaken about motion sickness)
Or do you accept that they get travel-sick and that you are wrong.

You do realise that just one person is enough to kill your theory , don't you?

But, of course, we already knew that.
Nausea and nautical have the same linguistic roots.
The phenomenon of seasickness has been documented for centuries.
And so your claim that it's anything to do with engines is nonsense.


The real irony here is that all your silly claims ae anecdotal; they are just a story that you (and only you) tell.

For the same reason, the  spinning motion method is not effective for motion sickness caused by 3d video and low frequency noise.
Therefore, in the article "The chair that stops you from vomiting in flight"
"If they make it through the chair, they should be able to fly," Shannon Scannon, a 359th AMDS aerospace and operational physiologist said.

ballet dancers and figure skater over years of training like pilots suppress input from the vestibular system and the response to that input, so they don't experience motion sickness when spinning.But the incidence rate of ballet dancer's carsickness is the same as that of ordinary people.
For example in the article "pirouettes and motion sickness - Adult Ballet Students - Ballet Talk for Dancers" on the Internet :As an adult with over thirty years of dancing  I also have had issues with motion sickness, even when turning well.Because rotation and low-frequency noise are two different causes of motion sickness.

and it can't work for seasickness.

The reason why workers on oil rigs or lighthouses won't get carsick must be that the low-frequency noise is relatively small.

You didn't consider the sound intensity decreases inversely proportional to the squared distance, that is, with 1/r≤ from the measuring point to the sound source, so that doubling of the distance deceases the sound intensity to a quarter of its initial value.

You are correct in saying that I didn't consider it.
Because it's wrong.
The inverse square law applies if you are considering a point source of sound (or light) but if you are considering an extended source such as the sea the fall off with distance is much slower. For a very large flat source, such as the sea, there's actually an inverse zeroth power law. The intensity is independent of distance. (That's why the absorption by air is important and that's why I pointed out that low frequency sounds carry well.)

Did you not know about that?

Also, someone sitting on the harbour wall watching the waves is much closer to them than someone on the top deck of a cruise ship, but only the ship-board one will get sick.

This is because you are wrong.

When you are 0.1M away from the aircraft engine, you will get airsick when you hear the noise of the aircraft engine. When you are 0.2m away from the aircraft engine, you will not get airsick due to the reduction of sound intensity.
Of course, the data of 0.1M and 0.2m are just speculation. No scientists have ever done experimental verification on the specific data.The purpose is to explain that the distance between carsickness, airsickness and sound source is very large.

Post by: sgroclkc on 23/08/2021 23:27:13
In addition, the sound intensity of low-frequency noise will become very large due to good sealing. When physicists do experiments with low-frequency noise, in order to increase the sound intensity, they must let the participants wear oxygen masks and enter a place similar to a space capsule to do experiments.Only in this way can the participants get carsick after hearing low-frequency noise.

Because the low-frequency noise generated by the car is relatively small, only the car with good sealing will make the low-frequency noise very large and make people carsick.Since trucks, motorcycles and tractors do not have cars with good sealing, the low-frequency noise is very small and they will not get carsick.

Because you, like those experts who study motion sickness, don't understand the physical properties of low-frequency noise, you come to the wrong conclusion.For example, in 1997, Professor Yu Lishen, China's most authoritative expert on Sports diseases at the Beijing Air Force Institute of Aeronautical medicine, once asked me a question: why do you hear a very loud noise when flying over the airport, but you won't get airsick?

Ma Dayou, a famous Chinese physical acoustician (refer to Wikipedia), has long pointed out that carsickness and airsickness are caused by infrasound noise. His experiments on low-frequency noise are also done in places similar to space capsules.More than ten years ago, I hoped academician Ma Dayou would expose the scientific scam of the theory of motion sickness. He replied to me that he was over 90 years old. Moreover, he was not a medical expert and had no energy to pay attention to medical problems.

Motion sickness theory,does not explain why presumably weak stimuli such as slow ship movements and a slow-moving car often result in motion sickness while more powerful and active movements such as walking, jumping, and swimming do not usually cause motion sickness.People who gets carsickness in a car usually can travel in trains ,trucks,tractors,motorcycles without any discomfort at all.
For example, sometimes when I take a bus to the Nanpu Bridge in Shanghai, I encounter a traffic jam, and the speed of the car is very slow. However, because the car is driving upward, the driver must always refuel the door, and the noise generated by the engine is relatively large, so I am easy to get carsick.

Yes it does.
Why lie about it?

On the other hand, a pedestrian next to the traffic is exposed to almost the same sound as the occupants of the slow car or whatever and they do not get motion sickness..
So your idea that it is due to sound does not work, does it?

Sorry, I didn't express my opinion correctly.I mean, the low-frequency noise generated by the car is too small to make people carsick directly like the noise generated by the aircraft engine. Cars must amplify the intensity of low-frequency noise in a completely closed place to make people carsick.

After I saw it in 1997, I introduced academician Ma Dayou's opinion to Professor Yu Lisheng, a Chinese motion sickness expert. He replied to me that this opinion is very valuable.

Open the windows
Fresh air often can stave off carsickness if someone starts to feel ill. Even just opening a window or sunroof a small bit can get enough air in to settle queasiness. You may also want to take any air fresheners out of the car before your trip. Scents and odors can cause sensitivity that leads to feeling ill as well.
His method is correct, but his explanation is wrong. The reason why carsickness can be avoided after opening the window is that the low-frequency noise is reduced.

When the car is in neutral and the car is stationary, step on the car accelerator to the bottom to maximize the low-frequency noise in the car, It is bound to make people with good hearing carsick.

No motion experiment has replicated the symptoms of carsickness and seasickness.Therefore, so far, no motion sickness expert claims to have found the causes of carsickness and seasickness.Now all the theories of motion sickness are a hypothesis!

Virtual reality sickness - Wikipedia :exposure to a virtual environment causes symptoms that are similar to motion sickness symptoms.
In other words, the symptoms of motion sickness and seasickness cannot be reproduced in VR experiment: VR is not the cause of carsickness and seasickness.If a motion sickness expert claims to have discovered the causes of carsickness and seasickness, mankind will immediately find a way to completely avoid carsickness and seasickness. This motion sickness expert will be nominated for the Nobel Prize and won the Nobel Prize in a few years. However, for more than 100 years, mankind has made no progress in solving the problem of carsickness and seasickness, and no sports  motion sickness expert has been nominated for the Nobel Prize.

His method is correct, but his explanation is wrong.
No
People who suffer from motion sickness (who are the actual experts) will tell you that strong odours make symptoms worse.
I designed an experiment that everyone can do to prove that carsickness is caused by low-frequency noise and has nothing to do with motion.It is to select a car with large low-frequency noise and easy to make people feel carsick, completely close the window, and the people participating in the experiment must wear an oxygen mask (to avoid suffocation and death when the air is not circulating). When the car is in neutral and the car is stationary, step on the car accelerator to the bottom to maximize the low-frequency noise in the car, It is bound to make people with good hearing carsick.
A similar experiment is done countless times every day.
The driver is exposed to the same sound as the passengers, but only the passengers get sick.
Drivers or aviators long-term exposure to car Low frequency noise or after repeated exposures to the flying environment.will cause a temporary neurosensory low frequency hearing loss. Therefore, the driver or aviators will not get carsickness or airsickness.Airsickness or carsickness may also occur when a previously adapted individual returns to duty after a period of non-flying.This is because low-frequency hearing has been restored.

Similarly, there are scientific scams that regard scientific hypotheses that have not been confirmed by experiments as scientific theories, as well as earthquake theory, nightmare theory and stomach disease theory. The scientific scam of stomach disease theory, although the vested interests try to attack the experimental results of Helicobacter pylori of scientific researchers, this scam has now been exposed. The scientific experimental results of Helicobacter pylori have been recognized and won the Nobel Prize.When gastrologists saw the experimental results of gastric diseases caused by Helicobacter pylori and knew that their lies were about to be exposed, the despicable behavior of gastrologists was exactly the same as that of motion sickness researchers, leading to the burial of this great new scientific discovery for many years.

Further, Dr. Marshall said, "The fact that the big drug companies who were supporting the journal articles ignored H. pylori was far more effective than actually saying that a bacterial cause was not true because if they had said it was false, or not important, they would have created a controversy and maybe media interest."

 

Dr. Samuel Hellman, a former dean of the University of Chicago's Pritzker School of Medicine, said that doctors "often fall in love with a hypothesis, and that holds in my field, cancer."

Taking the hypothesis that has not been confirmed by repeatable experiments as a scientific theory has caused great losses to mankind. However, because the peers in the whole scientific community have participated in it, even if the scientific fraud has been exposed, no scientist will be punished. Academic plagiarism or plagiarism does little harm to mankind. However, as it is a personal behavior, once it is exposed, the scientist will be severely punished.

When the scientific scam that stomach disease is caused by psychological stress is exposed, human beings should learn a lesson and say no to any scientific scam that regards the hypothesis that has not been confirmed by repeated experiments as a scientific theory, it will not appear. Until now, the three scientific scams of nightmare, motion sickness and earthquake still harm human beings. My nightmares, motion sickness and earthquake, These three major scientific discoveries have not been recognized by the scientific community.

In 2009, my opinions above were strongly opposed by all on the website forum consistently when I first published them on the website of International Association for the Study of Dreams. After several years of impassioned debate people on the website forum, everyone consistently approved my opinion that these dreams are of no any special meaning and the causes of dreams are very simple. Since March 2009, nobody has published dream-related articles on the website forum. In the end of  year, the website forum had to be closed. After knowing the reasons of nightmares, sleep paralysis, flying dream and falling dream , nobody will believe the dream theories of Freud and other oneiromancy masters. The disclosure of scientific mysteries such as the nightmare , sleep paralysis, flying dream and falling dream is equivalent to sentencing the dream theories of Freud and other oneiromancy masters to death.

However, the international dream research association is still promoting the pseudo scientific theory of dreams, and no authoritative figure has admitted his mistakes. Originally, authority figures should be more honest than ordinary people, but in the face of great interests, authority figures are more dishonest than ordinary people and prefer to lie.
For decades, after authoritative Chinese scientists, popular science writers, and editors of publishing houses have seen the scientific theories that I put forward about nightmares, motion sickness, and earthquakes that can be verified or falsified, they all know that the nightmare theory, motion sickness theory, and earthquake theory are pseudosciences. However, only very few Chinese experts and editors have replied to me acknowledging their mistakes. So far, no authoritative Chinese scientist, publishing house, or popular science writer has publicly corrected their mistakes. These three pseudo-scientific theories are still published on various authoritative websites in China, but netizens are prohibited from commenting. Otherwise, only by comparing the two theories, they will immediately know that these three authoritative theories are pseudo-sciences.

In order not to change the status quo of benefit distribution, all science writers such as Fang Zhouzi in China have stopped popularizing science on the Internet (Fang Zhouzi still publishes articles on English Facebook), and various scientific forums and psychology forums on the Internet in China have been closed (a very small number of scientific forums in China have not been closed, but netizens are no longer allowed to comment on these three pseudo-scientific articles), The popular science book "One Hundred Thousand Whys", previously praised by the Chinese news media as affecting several generations of people published by Shanghai Children's Publishing House and is republished every few years, has not been republished for more than ten years.

Low frequency noise is difficult to be heard by people's ears. If you can't hear low-frequency noise, it doesn't mean there is no low-frequency noise. Physicists reproduced the symptoms of carsickness through this low-frequency noise experiment. Therefore, physicists announced that they had found the cause of carsickness.Now, the motion sickness experiments of all medical experts in the world can not replicate the symptoms of carsickness, but can only simulate the symptoms of carsickness.Therefore, medical experts recognize that the cause of carsickness is still unknown.

Adverse Health Effects of Industrial Wind Turbine Noise: How the Ear and Brain Process Infrasound
An experiment in the late 1980s, conducted using training-mission scenarios with Navy pilots, showed that motion sickness was associated with significant amounts of acoustic energy inside the flight cabin over the frequency range from just under 1 Hz to as low as 0.05 Hz (the nauseogenic range). Maximum sensitivity occurred at approximately 0.2 Hz.

This is related to people's hearing of low-frequency noise. People with good low-frequency hearing are easy to get carsick, while deaf people who can't hear low-frequency noise won't get carsick at all. For example,Drivers or aviators long-term exposure to car Low frequency noise or after repeated exposures to the flying environment.will cause a temporary neurosensory low frequency hearing loss.

Very low frequencies which are inaudible and are classed as infrasound can cause nausea and disorientation when delivered at high intensity to the body. This is caused by resonance within body cavities. This phenomenon has no connection with motion sickness(here's a clue-why is it called "motion" sickness?). Anyway since one cannot hear these frequencies, one cannot argue that these induce problems through the sense of hearing.
