This Is Why We Get Sleepy in Cars

The condition is called carcolepsy and it can be dangerous when driving.

You have seen it before. You start on a weekend car ride and before you even know it you are dozing off in the back fast asleep.

Cars indeed, or rather car rides, have a habit of making us sleepy. But why? Is there some biological reason or is it purely psychological?

YouTube science show SciShow is here to explain exactly why. In their usual upbeat and well-illustrated style they go through the logical reasons why we fall asleep in cars.

Interestingly the term for this condition is called carcolepsy. But the truth is we don't know exactly why it happens.

Some speculate it is the noise others the vibration. Studies have been done on the matter but so far nothing has been conclusive.

Scishow explores these studies and shares their data with us. Yet, even our nerdy friends at the show don't have a final conclusion on what exactly causes carcolepsy.

Why is it important to know? Because maybe in the future we can build cars that avoid carcolepsy.
