A helmet is a protective headgear designed to protect the wearer's head from injuries caused by impacts, collisions, or falling debris. It is typically made from hard, durable materials such as metal, plastic, or Kevlar, and features a cushioned lining that provides shock absorption and comfort. Helmets are widely used by military personnel, law enforcement officers, construction workers, athletes, and individuals engaging in extreme sports such as cycling, skiing, and rock climbing. Some helmets also come equipped with additional features such as ventilation, visors, and communication systems. Properly fitting and correctly worn helmets can significantly reduce the risk of head injuries in accidents.
