What can be a consequence of wearing a helmet that does not fit properly?

Wearing a helmet that does not fit properly can significantly increase the risk of sustaining head injuries. A helmet that is too loose may shift during an impact, failing to offer the necessary coverage and protection to critical areas of the head. Conversely, a helmet that is too tight can cause discomfort and distractions, encouraging the wearer to remove it at inopportune times, which can also result in increased vulnerability to head injuries.

Proper fit is crucial for ensuring that safety features like impact absorption and coverage of vulnerable areas such as the temples and forehead are effective. A well-fitted helmet stays securely in place during activities, allowing it to function as intended, providing the maximum level of safety. Other options may speak to comfort or airflow, but without proper fit, the primary purpose of the helmet—protecting against head trauma—cannot be effectively achieved.
