Why Do We Get Motion Sickness?

The majority of the population will at some point have to contend with that dreaded icky feeling of spewing their guts as they ride in a train, plane or automobile. But why do we get motion sickness, and is there any way we can stop it?

In fact, it’s a result of our senses coming into conflict: vibrations and movement cause the fluids in our inner ears to mis-match with what our eyes see, and the result is nausea. Interestingly, it’s not just humans that suffer either: horses, cats and dogs have all shown symptoms, too.

But is there any way to stop it? Aside from avoiding travel, not really: it can only be treated, not prevented. So, sit up front, focus on the distance, take some dramamine and ride it out. [YouTube]
