It is better to not get hit in the head but sometimes it just ends up that way. Hockey helmets are designed like most helmets with the ability to absorb most of the energy from impact. The thing that I believe separates a hockey helmet from a standard football helmet is the fact that the top of the line hockey helmet rotates a little around your head without jerking your head in the initial impact. (I don't Know enough about football equipment to speak on behalf of the equipment) However, most injuries that occur to the head are caused from the initial jerk of the head when the brain remains still for a moment while the head moves. As this movement happens it yanks on blood vessels and nerves causing strain on the head and if bad enough an actual brain bleed or a concussion. This is why I wear the top of the line helmet now because previously having a really bad concussion and now I must wear it to prevent future ones. With this helmet no one is safe from every hit but with the ability to rotate a little around your head it gives you a slight edge over other helmets.
