A helmet is a protective headgear designed to protect the skull and brain from injuries during falls, crashes, or impacts. Helmets are essential in many activities like cycling, motorcycling, sports, and construction work, and are often required by law. Wearing a helmet is one of the simplest and most effective ways to protect yourself—whether you're biking, riding a motorcycle, or working in hazardous conditions.
