      It’s all to do with the liquid and tiny hairs in your ears. When you turn your head the fluid move and the hairs follow it to help you keep your ballance. When you spin the fluid and hairs go all out of sync and that is what causes you to loose ballance. You can also feel dizzy when you have an ear infection in one ear.

      Because we have little motion sensors in our ears that contain fluid and help us balance – when we spin around, this fluid moves around too. When we suddenly stop – the fluid keeps moving for a short while because of it’s momentum. So even though we are still, our body thinks we are spinning and starts to try and react to re-balance you – the result being that it un-balances you!

      Ah, it’s a conflict in the information your brain receives.

      There is a system in your ear that is made to sense movement, and it relies on a fluid that keeps spinning for a short while even when you stopped. That tells your brain that you are still moving and your body will try to adjust accordingly. Your eyes, for example, already tell your brain that you are stopped so there is a bit of an argument until your ear catches up with reality 😉
