Question

Here’s a question many people might want to try out at home or at work. Take and office chair and spin around for about 30 seconds. Why does that make you feel sick?

Answer

Kat: I think this is all to do with the vestibular system, if that's the right word. I'm sure Chris will pick me up on this from Australia if I'm wrong.

Basically, inside your ears you have a system of interconnecting tubes that are all at right-angles to each other. In each plane: up down, left and right that are filled with fluid. They tell you which way is up and which way is left and right in your head so you know if you're standing up or lying down.

If you spin very fast the fluid in these canals will spin round. If you stop very suddenly, as in stopping an office chair, you stop but the fluid in your ears is still going. Your brain gets all confused. You think you're still spinning but your eyes are telling you that you're not spinning so it manifests as feeling very sick.

Ben: Isn't this why people feel sick in long car journeys at all?

Kat: Exactly, it's when you get an imbalance between what your ears are telling your brain and what your eyes are telling your brain. You get confused and that makes you feel nauseous.

I went on a spinny thing at the park
How do I feel better swiftly?

Ive done this plenty of times before and yet only today its started to effect me...Y is this?

I feel sick from spinning on a thing in Park, how long does this last and how can I treat it while I'm at home?

im dealing with it so idk

I vomit

But why is sickness your body's reaction? It seems like whenever it has some kind of unknown problem it's just like, "umm.. better throw up."

How do i get rid of this feeling! Help please☹️

Try to concentrate on the landscape, don't move your eyes quickly, be calm and drink water.

Every time I'm at the park I go or something that will spin me in circles I try to avoid it, why? Because I get very sick and I get nausea all day and throw up and it lasts all day and don't know the reason why, help
