What factor can decrease a survivor's chances of rescue?

Lack of signaling for help significantly decreases a survivor's chances of rescue because signaling is a fundamental method for attracting attention and making one’s presence known to rescuers. When individuals in distress fail to use available signaling devices, such as flares, whistles, or mirrors, they may remain unnoticed, extending the duration of their perilous situation. Effective signaling not only alerts search and rescue teams but also increases the likelihood of being spotted by passing vessels or aircraft.

In contrast, effective preparation prior to emergencies, clear communication among group members, and maintaining high morale are all strategies that can enhance survival chances. Preparation ensures that individuals know what to do in an emergency; effective communication fosters teamwork and coordination; and high morale helps survivors stay focused and hopeful, all contributing positively to the scenario.
