A recent report from Washington University in St Louis shows that a standard football helmet can help protect the brains of soccer players when they hit the ball with their heads (1).
A previous study from the Netherlands shows that soccer players have lower scores in tests measuring intelligence than middle-distance runners and swimmers (2). Twenty-seven percent of soccer players have had a concussion that caused them to pass out and 22 percent had between two and five concussions.
Expect brain damage when you hit the ball with your head. Your brain bounces around in its sack of fluid, hitting one side of your skull and then the other, causing bruising and bleeding. Woodpeckers don't suffer concussions when they bang their heads because their brains don't bounce around. A helmet protects your brain only if it prevents your head from moving inside the helmet when it is hit. Helmets are supposed to fit your head like a woodpecker's skull.
