People showing superhuman strength during an emergency?

During emergencies, individuals sometimes display superhuman strength, often referred to as "hysterical strength," which allows them to perform extraordinary feats, such as lifting heavy objects or rescuing trapped victims. This phenomenon is attributed to a surge of adrenaline and the body's fight-or-flight response, enabling temporary increases in physical capacity. While these instances are remarkable, they also highlight the profound effects of stress and urgency on human performance. However, such strength is usually short-lived and not sustainable under normal conditions.
