[edit] Yes, but why sickness?

I can understand that your brain receives conflicting signals from your eyes and vestibular system causing confusion to the brain, but why should the outcome of this be nausea? It doesn't seem to make much sense! --CharlesC 22:56, 21 May 2006 (UTC)

  • Because the brain thinks one is hallucinating and that this is caused intoxication. Nausea is induced because it leads to vomiting an thus clearance of some of the hallucinogenic toxin. 70.22.58.75 21:51, 28 April 2007 (UTC)

So, uhm, what about those acupressure wristbands that purportedly prevent motion sickness? Any scientific background on that? -- Kimiko 19:24, 23 Jul 2004 (UTC)

These (along with tongue spray, some kind of hand shock therapy, ginger pills, placebo and a commercial product) were tested on a recent episode of MythBusters, the ginger pills seemed to work best, followed by the commercial product. The placebo also worked on one of the two test subjects. The rest of the products, including the wristbands, did not seem to have much effect. --GalFisk 13:40, 18 November 2005 (UTC)
The article itself quotes the ginger pills as "citation needed". Can we use the MythBuster episode as a 'field test' in the Treatment section? Jappalang 03:28, 29 October 2007 (UTC)

What about an explanation for how someone can experience motion sickness without having the endolymph (the fluid found in the semicircular canals of the inner ears) stirred up? Like when you watch a movie from the front row.

In the Canadian 'Digital Living' journal HUB magazine's (March, 2006), Total Gamer column, writer Erin Bell refers to the American Academy of Pediatrics' explanation that motion sickness is caused by confusion between a range of sensors throughout the body. The liquid in the inner ear, actually provides a lot of information about depth and height as we look up and down; the eyes and neck help keep us oriented as we move around our bodies and our heads; and "nerves in the ankles, knees and other joints register information about the surface we are walking on." Bell approaches the subject in terms of a personal quest to avoid video game-induced nausea, and reports similar negative experiences between dramamine (Gravol), Bornine, and Transderm V in the form of drowsiness. Bell also reports better success with ginger and peppermint oil, and even dramatic results with Sea Bands, a type of accupressure wrist devices I believe Kimiko refers to above. Interestingly, after a period of using the bands to play formerly troublesome games with no ill effects, Bell inadvertantly indulged one day without the bands -- and felt just fine. One might suggest that this is an example of the placebo effect, but I would suggest it may instead be the result of systematic desensitization; perhaps the bands did work for the time they were used, and being free to play without ill effect permitted the author's metabolism to 'learn' to tolerate the conflicitng information. This would explain the phenomenon of 'getting your sea legs', usually earned by protracted nausea and vomiting. The gamer's experience suggests that the suffering may not be a necessary part of becoming acclimatized. The trick may be to find your cure, and to stick with the activity long enough to overcome it. As an aside, it would be interesting to see if a 'cured' motion sickness candidate is symptom free across other conducive environments. For example, if beside visual stimulation Bell also experienced motion sickness thorugh kinetic stimuli as in rocking below deck on a boat, would the desensitization achieved through video games cross over to the sea sickness as well? If not, my suggestion would be peanut butter. A rounded teaspoon of peanut butter does wonders to settle your stomach on the sea, Billy... --BK 07:24, 16 March 2006 (UTC)


Old Trials I participated in trials (with many other subjects - I think about 30 in all)investigating motion sickness at the institute of RAF medicine at RAE Farnborough around 1964 to 1965. Broadly, all subjects were presented with two situations of sensory conflict. They were subjected both to motion with no visual cues (a projected horizon which appeared to be static with reference to their bodies), and on another run they were subjected to a moving horizon with no real motion occurring. Several different frequencies of motion were tested for each subject in different sequencies. Several findings were clear. First, most subjects felt a degree of nausea, and each subject had their own critical frequency which induced nausea quickest. This was independent of whether the nausea was motion induced or visually induced. Second, most subjects slowly became less sensitive to motion as the experiments progessed. Third, those subjects already familiar with violent motion were least sensitive. Lastly, two subjects appeared to be immune. I'm sorry, I don't know whether the results were published, and therefore verifiable.

[edit] Relief bands

Removed from article as it sounds like quackery and no reference provided:

Another available treatment is Relief Band, a watch-shaped product worn on the wrist. It sends a painless electronic pulse through an acupuncture point. While it has been independently proven to relieve nausea caused by chemotherapy and other poison-induced forms of nausea, an independent study also found it provides no relief for nausea caused by motion sickness. (Miller and Muth 2004))

Anything about why some people don't get motion sick? Maxwellstragedy




Hello, I usually never get car sick when we start traveling in the morning when I get up im usually fine. But for the last few years when we get up around 4 AM and before to leave in the car I always get motion sickness It usually right after I wake up. When we leave in the car I feel sick and nauseous. Does any Have any idea why this only happens in the morning and how to stop it?

[edit] 3D computer games

Anyone know how motion sickness when playing 3D computer games (like first person shooters) is caused? It happens to me sometimes. —The preceding unsigned comment was added by 199.111.229.131 (talk) 23:33, 14 January 2007 (UTC).

[edit] Merging - No

Motion sickness is not sea sickness and vice-versa. Each has its parameters that some are subject to which might not be induced on land, sea or air. Ronbo76 06:29, 17 January 2007 (UTC)

  • Having two items on the same page does not mean they're synonymous, they would have their own sections. Vicarious 04:33, 21 February 2007 (UTC)
  • According to "the most common theory" (see main article and 1 - the reference being a section of the Navy's General Medical Officer Manual and thus containing generally accepted theories) seasickness, carsickness, simulation sickness, airsickness and space sickness are all the same thing: a conflict between the motion perceived by the eyes and by the inner ear being interpreted by the brain as intoxication with a hallucinogenic substance. Consequently, merging is appropriate indeed. 70.22.58.75 21:51, 28 April 2007 (UTC)

[edit] Chinese version is completely wrong. Help!!!

The Chinese wikipedia entry for motion sickness is completely wrong. It's used by a pseudoscientist to promote his anti-science message. I have changed it back into the translation of the first sentence of the English version. How do I prevent this be changed back into the wrong content again? This guy is disrupting several chinese bbs's to promote his pseudosience. He will certainly come back and vandalize the wiki site again. I would also like help in translating the whole entry.

[edit] Imagined simulation motion sickness?

Am I the only person who doesn't get simulation sickness from viewing it on a screen but instead from imagining severe motion (in my case, waves of water or water beds, etc.) while laying with my eyes closed? I don't get too bad of motion sickness while in a pool but that night, hours and hours after swimming I'm kept awake by constantly feeling sick from dreaming of / picturing waves or feeling as if I'm in a body of water. I can't seem to find anything about this, though. I would assume it is the same as the simulation sickness mentioned in the article that is only contributed to video-games, but I have never once experienced this while playing any manner of first person video-game. Does anyone else get this? TealMan 11:19, 7 July 2007 (UTC)
