To quote your standard-fare bro, “you had an epic night.” Upon arriving home, you do a symbolic teeth-brushing, take off half your clothes and flop into bed as excitedly as you’d raged an hour earlier. But, as your eyelids close, the dreaded happens: The room begins to tilt — that's right, you’ve got the spins. You want to give into your exhaustion, but you shouldn't. Falling asleep with the spins won't do anything but ruin your morning.
The source of the spins isn't a mystery — blame 'em on the alcohol. But your ears are the middleman. Beyond helping you hear, the holes on the sides of your head play a key role in maintaining balance. When you move, three fluid-filled structures inside the inner ear, called the semicircular canals, work to keep you upright and centered. Inside the canals, tiny hairs bend in the direction of gravity and send an electrical signal to the brain, at which point, you feel motion. This complex of sacs and canals is called the vestibular system.
Alcohol throws off the process by diluting your blood. Denser, booze-filled blood causes the inner ear to swell, which pushes on the motion-sensitive hairs, misfiring an electrical signal. As a result, your brain thinks you’re body is moving when you're lying down, still as a corpse and drunk as a sailor. Closing your eyes only makes matters worse, by robbing you of visual cues, e.g., your dresser, that can help correct illusions of motion.
Instead, you should open your eyes, sit up and put at least one foot (or both, and maybe a hand, too) on a hard, still surface to regain your sense of equilibrium. But, the only way to get rid of the spins is to wait them out.
And that's about it. The science of the spins is limited, at best. In fact, Joris Verster, a professor at Utrecht University who studies hangovers, said he's unaware of any spins-centric research.
So, next time you crawl into bed and feel like you're on a Tilt-a-Whirl, get up, get a snack and get sober, or somewhere near it.
