Use Your Head on the Slopes
|
SUNDAY, Dec. 12 (HealthDayNews) -- Ski helmets can save you from head injury on the slopes, but some experts say there might be a slightly increased risk of neck injuries when you wear a helmet. That''s because the lower rear edge of the helmet could act as a pivot point to cause injury. A helmet might also increase the risk of whiplash injuries. Whiplash can occur with a sudden movement of the head, which can lead to tearing of muscles, ligaments and other soft tissues. Even so, experts agree helmets can prevent head injuries. They''re most effective at providing protection at speeds of 12 miles per hour or slower, according to the National Ski Areas Association. If you''re skiing at higher speeds and hit a tree or other stationery object, the helmet might not prevent or reduce serious injury. If you choose to wear a helmet while skiing or snowboarding, pick one that conforms to the American Society of Testing and Materials (ASTM) standards for ski helmets, the association suggests. Be sure it fits properly; ask for help when buying it. And make sure it doesn''t restrict your vision or your hearing. Wearing a helmet that''s designed for other sports may increase whiplash risk, other safety experts say. A ski helmet is not a guarantee you won''t get injured on the slopes. However, it may help prevent head injuries, abrasions, lacerations and contusions, even while slightly increasing your neck injury risk. If you crash and your neck hurts, seek medical care to rule out whiplash. More information More details on helmets are at SkiHelmets.com
