How football helmets fail to protect

Hi,
There's no such thing as a concussion-proof football helmet — most experts agree on that. But today’s helmets aren’t doing as much as they could to help football’s concussion epidemic. Right now, the standard helmet is mostly designed to prevent skull fractures and cushion players against direct, linear hits. They do almost nothing for the hits that twist players’ heads violently. In fact, the helmet may partly make those kind of hits worse. The need for better helmets is becoming even more pressing: a growing body of research shows that repeated concussions and impacts come with serious risks. The brains of many former football players have shown signs of neurodegenerative disease. The effects of this condition can include debilitating symptoms, such as memory loss, erratic behavior, impaired judgment, and depression. The head needs even more protection than originally thought. oday's standard football helmet has two primary layers: a hard polycarbonate outer shell and an inner layer of padding, usually made of foam. The harder layer is to protect the skull, while the cushioning is meant to absorb hits. But helmets often fit snugly on the head; this type of design is crucial for some aspects of protection. It can also be dangerous when hits to the side of the helmet — called rotational hits — occur, twisting the wearer’s head along with the helmet. These rotational hits are at least as dangerous as direct hits — and a few studies suggest they may be worse.
