Why people become unconscious after they hit something with their head?
In: Biology
Yor brain is surprisingly delicate. When you hit your head hard you shake your brain in your skull(if you want a larger example of how this works, think about when you slam on the breaks while driving, you get thrown forward). When your brain slams into the side/front/back of your skull hard enough it can cause your brain to get injured. When that injury happens your body might skip a beat before it recovers(very few blows to the head actually result in you going fully unconscious for more than a split second, and in fact if you fall unconscious from hitting your head there is a significant risk that you are about to die or at least suffer long term mental damage)
