What is a secondary benefit of bracing for impact besides reducing flailing?

Bracing for impact serves multiple purposes, and while the most well-known benefit is the reduction of flailing during a crash, a secondary benefit is reducing secondary impact. When passengers brace properly, they are more likely to maintain a controlled posture, which minimizes the risk of additional injuries from subsequent collisions with objects within the aircraft during a crash. This preparation helps to keep passengers safe from further harm once the initial impact has occurred.

This is especially important in high-stress situations, as a secondary impact might occur due to the inertial forces acting on the body or from debris within the cabin. By reducing the likelihood of injuries during these secondary impacts, bracing provides an essential safety measure for passengers in the event of an accident, reinforcing the importance of following instructions from the flight crew regarding proper bracing techniques.
