Ski helmets help in case of an accident. Helmets protect the head from mild and severe shocks. The level of shocks dampened by each helmet is standardized and skiers are required to wear hearing protection as a result. Ski helmets have been shown to reduce impact force and brain trauma. Most ski accidents can be mild, but a ski helmet can protect the head even in case of a minor accident which might lead to considerable brain issues on the spot or in time. Ski helmets also keep the head warm during the skiing session. Most body heat is eliminated through the head and it’s mandatory to stay warm. Unlike other headgear, a helmet is also aerodynamic. It reduces air drag and at the same time, it improves skiing performance. Most importantly, a good ski helmet improves skiing safety when used together with other protective gear.
