What happens if a helmet is worn too loose?

Wearing a helmet too loose significantly compromises its effectiveness in protecting the wearer during an impact. A helmet is designed to stay securely in place to provide maximum protection by absorbing and distributing the force of an impact, minimizing the risk of head injuries. If the helmet is not fitted properly, it can slide or come off entirely when the individual experiences a sudden jolt or collision, leaving the head exposed to the very dangers the helmet is meant to mitigate. Proper fitting ensures that the helmet is able to perform its safety function effectively, while a loose helmet can fail to offer any substantial protection in critical situations.

Other considerations, such as comfort and appearance, while important, do not directly impact the primary purpose of a helmet, which is to shield the head from injury.
