Risks of injury in cross-country skiing, downhill skiing and snowboarding are largely due to the characteristics, speed, equipment and level of difficulty of the sport. The preventative means are also found among these factors. Regardless of the injuries associated with these winter sports, skiing is considered as a safe form of physical exercise. Furthermore, the risk of injury in downhill skiing and snowboarding is acceptable provided that risk-taking is in accord with the skill level. The helmet is an easy and inexpensive means in reducing severe injuries (head injuries) occurring in downhill skiing and snowboarding. Helmet use should thus be encouraged.
