The Science Of The Spins

Given that today is New Year’s Eve — what I generally refer to as Amateur Drinking Day — I thought this science lesson from Mental Floss on what causes the spins was an appropriate topic. In Why Does Alcohol Cause the Spins?, author Matt Soniak explains that sometimes after an evening’s drinking that the room appears to be spinning out of control. You lie down, but it doesn’t help. No matter what you do, the vertigo persists, causing great discomfort and often the loss of lunch, dinner and everything else that used to be in your stomach. Here’s why.

The spins happen because of an odd effect alcohol has on your ears — specifically, on three tiny, fluid-filled structures called the semicircular canals. Inside each of these canals is a fluid called endolymph and a gelationous structure called the cupula, which is filled with cells covered in fine, hair-like stereocilia.

As you move around, the movement of the endolymph lags behind the more solid cupula, distorting and bending it — and those little hairs. When the hairs bend, the electrical signal they send to your brain is altered, helping you to make sense of the rotations your head experiences on each of the three planes the canals sit on — movements up and down, left and right and backward and forward — and keep your balance.

Booze throws this system out of whack. Alcohol thins the blood, and when boozy blood travels to the inner ear, it creates a density difference between the cupula and the fluid in the canals, and distorts the cupula’s shape. The little hairs bend and send a signal to your brain that tells it you’re rotating when you’re really not, and this illusion of motion makes it seem like the room is spinning.

Some of the things that you most want to do when you’re good and drunk, like lie down and close your eyes, make the sensation worse, since you don’t have any visual or physical cues to counteract the false sense of motion. Looking at a fixed object and keeping your feet planted on the ground can help lessen the effect, but there’s no real way to stop it.

So now you know. The bad news is there’s pretty much nothing you can do about it apart from practicing moderation and drinking plenty of water. If I know I’ll be drinking a lot, I try to eat a hearty meal beforehand, drink a glass of water in between each beer, snack during the party and take some Advil and Vitamin B before going to sleep. Happy New Year everybody.

Maybe this will help; maybe not.
