Your liver can only do so much at once. When you drink more alcohol than your liver can process at the time, it gets released into your bloodstream and into a fluid called the endolymph in your ears. This fluid sloshes around your ears to give you a sense of how your body is oriented in space.

Alcohol thins out the endolymph so it moves around differently than what your body expects. This process makes you feel dizzy. Knowledge of the scientific processes behind your bodily functions allows you to better monitor your behaviors. You can think back to the biology of alcohol’s effects on your body to know when your liver is overwhelmed and thus when to stop drinking.
