>I recently found out that helmets do nothing to prevent concussion regardless of the sport. Saying they "do nothing" isn't completely true, at least based off more recent designs, but it is generally true that helmets are less effective than most people think. The problem is that your brain can move around in your skull so there is only so much you can do by adding protection outside of your skull. Think of it like putting an egg in a glass jar. Adding padding to the outside of the jar might be enough to save the egg in a single drop, but it isn't going to stop the egg from breaking if you shake the jar. There is also the fact that safety equipment impacts behavior. Someone wearing a helmet is going to be more cavalier with their head than someone not wearing a helmet. It is possible this effect completely cancels out the slim benefits of a helmet which has caused some people to argue that a game like American football would actually become safer if helmets were outlawed. The main obstacle there is that we absolutely would see a rise in acute injuries like fractured skulls and those are tougher to ignore than the chronic brain damage that might take decades to reveal itself.
