A recent study conducted by the Institute of Medicine and the National Research shows that student athletes do not take enough precautions to allow themselves to heal after suffering a sports-related head injury. Too many young athletes rush back into playing after they suffer a concussion or impact to the head. There is a so-called "culture of resistance" when it comes to reporting concussions and complying with recommended treatment. Young people often do not want to sit out for the required time to recover if they are feeling better, and they may also feel pressure from coaches, parents, and team members to continue playing. While helmets, face masks, and mouth guards help protect against injuries such as skull fractures, they do not prevent concussions. A concussion occurs when the brain is jarred from being hit. This affects the brain's ability to function at the moment it happens and can have an affect on memory, balance, judgment, and sleep patterns. It takes about two weeks of physical and mental rest to recover from a concussion. Some states implemented laws that require stricter regulations of injured players so they would be monitored by a doctor before being allowed to return to the game.
