motion sickness
I've been thinking of writing a paper on motion sickness. We've been
studying space sickness in my astronautics class. As a man of action, adventure, and danger, I've experienced motion sickness many times. My instructor says that when he's been up in the space shuttle for several months and he gets back on land, he experiences some vertigo that takes about 20-25 minutes to go away. Many people have experiences this when leaving a boat. We call it getting our, "land legs," back. And for me it only takes a few seconds. But I've never spent six months on a boat. I've noticed many times while doing a fast descent on a black diamond and doing a hockey stop at the bottom, I often feel a sense of vertigo, which takes a moment to go away. Has anyone else felt this? I attribute this to gravity. While going downhill rapidly, gravity is reduced and your heart pumps more blood to your head. While stopping rapidly there is much more gravity pulling on you and the blood pools toward your legs. The same thing happens in zero-gravity. Any discussion on this will be appreciated. ------------------------------------------------------------- This signature is now the ultimate power in the Universe Horvath --- news://freenews.netfront.net/ - complaints: --- |

The same thing happens in zero-gravity I doubt the suggests relationship holds. rather, I suspect you unknowingly bumped your head on a fellow skier while transiting the downhill portion of your exciting ski journey leading to enhanced passion for all things downhill. |

Gee! I hadn't considered that. I had considered that you were an idiot. ------------------------------------------------------------- This signature is now the ultimate power in the Universe Horvath --- news://freenews.netfront.net/ - complaints: --- |

We covered the inner ear in class. Welcome to adulthood. Welcome to your senility. You missed the whole point of this discussion. This is not space camp where we earn a merit badge. This is a real college course taught in a major university, by a retired astronaut, to earn a real degree. I already know the causes of motion sickness, and the cures. I've experienced many types of motion sickness, to include seasickness, air sickness, car sickness, and the type that you get on certain rides at amusement parks. I'm looking for people who have experienced other types of motion sickness. For example, do you get vertigo or dizziness while skiing or riding the lifts or tram? Or do you know someone who does? A good example is Trunky, who only skis the green groomed runs, because his altitude sickness causes him to **** his pants when he stands at the top of a black diamond run. ------------------------------------------------------------- This signature is now the ultimate power in the Universe Horvath --- news://freenews.netfront.net/ - complaints: --- |

No, but I do know the frustration of having a non-standard problem for which there is thought to be A Standard Solution. How about this -- your eardrum is more sensitive than most to changes in altitude and this somehow affects your inner ear mechanisms? -- Cheers, Bev Don't you just KNOW that there is more than one Sierra Club member who is absolutely sure that the dinosaurs died out because of something humans did? |

Space sickness occurs in a zero gravity enviroment. Many times it's caused by the eyes. This was explained in class. They showed us pictures of famous people upside down and they were unrecognizable. Ever tried to read a paper upside down? It's nearly impossible. I've even heard of people who get motion sickness sitting on their couch playing video games. ------------------------------------------------------------- This signature is now the ultimate power in the Universe Horvath --- news://freenews.netfront.net/ - complaints: --- |

I took FauxPro video of my last skiing trip. The thing is set at wide angle and is mounted on a chest strap. Watching it full-screen makes me feel dizzy. I assume this is the seasickness thing caused by the difference between what your ears feel and your eyes see. I'm glad I bought a cheap one. The result is fine technically but sucks artistically. It claims to be phone-controllable, but whenever I try to link them up the android app crashes. I need to phone Wasp, but I dread talking to helpdroids. One of these days. -- Cheers, Bev Politicians are stupid like cats are stupid. |
