There are many reasons, or rather, excuses for not wearing riding helmets. Yet research shows that a properly fitted, safety-approved riding helmet can drastically reduce the risk of head injury. When a rider falls, the head is usually the first thing to impact the ground. The human skull can be shattered on impacts of 7 to 10 kilometers per hour, and horses gallop at over 60 kph. According to the Brain Injury Alliance of Kentucky, three out of every five equestrian accident deaths are caused by brain injuries, and there is four times the risk of mortality for non-helmeted riders who become injured.
