If we rotate ourselves in circles we start getting dizzy. If we close our eyes, we feel better.
(All of this provided there is not too much food in your stomach – which by nature of centrifugal force would cause something I guess)
So, which is it that causes nausea? – the brain, the stomach, or the eyes?
And why do we get dizzy?
Also, if we immediately rotate counter-direction, the dizziness subsides in just a few spins. What causes this?

The best way to explain this might be something you can do yourself.
Take a cup, fill it halfway with water and swirl it in your hand. It continues to spin after you stop, if you swirl it the other way you can reduce it (or just cause it to go the other way if you go too hard)
Now imagine that cup of water is actually the fluid that controls our balance (in our ears), the continued rotation causes the dizziness.
The nausea is similar to car sickness. Your ears are reporting spinning, but your eyes are saying you’re still (or at least aren’t spinning as fast as your balance thinks you are) and so, you have a disconnect between the two senses, which causes nausea.
Sensory overload.
The Brain is struggling to process rapidly changing visual information, so it’s kind of just throwing half of it away so it can get closer to what’s happening in real time.
Basically everything we see and hear is very close to, bit isn’t in real time, since it takes the brain time to process it. Bit since said time is so small it’s almost unnoticeable, it’s not really regarded as a factor.
But when you’re moving really fast, and your surroundings are rapidly changing, the brain starts overload protocol, which is to make you want to stop whatever you’re doing (if you’re doing it) by making you feel dizzy, and also blurring a lot of things and sometimes just throwing away entire pictures of whatever you are seeing. If you would be seeing things in 8k 720 fps like you usually do, your brain would simply short out because of not being able to handle the bombardment of sensory information.
