Motorcycle Helmet Performance: Blowing the Lid Off
If your brain is injured, swelling and inflammation often occur. Because there's no extra room inside your skull, your brain tries to squeeze down through the hole in the base of the skull. This creates pressure that injures the vital brain stem even further, often destroying the parts that control breathing and other basic body functions. If you're hit very violently on the jaw, as in a head-on impact, the force can be transmitted to the base of the skull, which can fracture and sever your spine. It's a common cause of death in helmeted motorcycle riders—and a very good reason to wear a full-face helmet and insist on thick EPS padding—not resilient foam—in the helmet's chin bar. When your brain collides with the inside of your skull, bony protrusions around your eyes, sinuses and other areas can cause severe damage to the brain. And if your head is twisted rapidly, the brain can lag behind, causing tearing and serious internal brain injury as it drags against the skull. A helmet is the best way to avoid such unpleasantries.
