What is the primary function of a helmet?

The primary function of a helmet is to protect the head from impacts and injuries. Helmets are specifically designed to absorb the energy from impacts and collisions, thereby reducing the risk of head injuries in the event of an accident. This is achieved through the materials and construction of the helmet, which include padding and a hard outer shell that provides a barrier against external forces.

While comfort, aesthetic appearance, and hair management are aspects that may be considered for riders, they are secondary to the essential protective role that helmets play in ensuring safety. The critical purpose of wearing a helmet is to safeguard the head during potentially dangerous activities like cycling, motorcycling, or other sports, making proper helmet use vital for reducing the severity of head traumas.
