The roller coaster is making lots of turns. You stomach starts to roll. Uh-oh, you think you’re going to …
Just what is it about a moving vehicle that sometimes makes you feel so sick? You may be surprised to learn that the problem doesn’t start in your stomach. It’s in your head!
The trouble begins when your brain gets different messages. Let’s say you are flying in an airplane and the ride gets bumpy. Structures inside your inner ear sense movement. Messages go to your brain saying that you are in motion.
However, sometimes what you feel is not the same as what you see. Inside the plane, your eyes see that the seats and walls are not moving. Your eyes send messages to your brain that you are still. Your brain can’t make sense of the different information. That’s when you may begin to fell sick.
Usually you can get used to the motion. Over time, your brain begins to make sense of things again. Your stomach settles down. In fact, you may be feeling cool and collected.
