Why do we get car sick? | Greg Foot | Head Squeeze

Thanks to Aaron Lloyd who sent this question from Facebook!

Car sick, sea sick, it's all the same. It all comes under the Motion Sick banner. Basically your body is getting conflicting signals.

If you're in a car or on a bus if you are looking at the floor or a book your eyes are telling you that you are not moving. But your ear is telling your brain that you are indeed moving. So instead of your body realising you are reading a book on a bus (normal enough) your body thinks it is being poisoned and the only way to deal with poison is to vomit it all up. Lovely.
The poison theory is one that many people use to explain the vomming. For others check out this link here: http://www.ncbi.nlm.nih.gov/pubmed/23000611


Top tip, to avoid getting motion sickness sit at the front of the bus or car and focus on the horizon. Or suck on ginger, that calms your stomach down.

Perhaps you're greener and you prefer two wheels better than four, find out which is best for performance; a lighter bike or a leaner body?
