While most of us travel in a bus, car, train or even plane feels sick. This generally happens when the vehicles are moving and we are eating or reading in it. And if you are not the one who experience this, then consider yourself lucky.
This phenomenon is known as motion sickness and if you are new to this concept, we are Now You Know and in this video we will tell you what Motion Sickness is and what causes it.
Almost 30% of the population experiences motion sickness and over 66% people experience it in extreme condition. This happens because our eyes and ears send two different messages to our brain.
Your eyes are seeing the inside of the vehicle which doesn't seem to be moving while your ear is telling your brain that you are accelerating. The vestibular system inside our ear contributes to balance and special orientation. The tiny hairs inside detect the movement of the fluid inside, allowing you to orient yourself.
These fluids tell the brain whether you are moving vertically or horizontally. Apart from that it senses which direction you are moving in and at what speed you are accelerating at.
So, your ears sense movement but your eyes couldn't see it.
Often in a car, boat or a plane, your vestibular system is transmitting signals to your brain from other senses. And this mis match of signals tell the brain that something is wrong.
But wait! Why does the mis match of signals lead to vomit?
When the brain receives two different signals from your eyes and ears, it senses that you have ingested some neurotoxins. And the best way to get rid of the toxin is to vomit.
