What is emphasized as a necessary skill for a diver in distress?

Calmness during emergency situations is emphasized as a necessary skill for a diver in distress because it directly impacts the diver's ability to think clearly and make rational decisions. When a diver encounters a distressing scenario, anxiety and panic can cloud judgment, potentially leading to poor choices that may exacerbate the situation. Remaining calm allows the diver to assess their surroundings, determine the best course of action, and communicate effectively with their dive buddy or team if needed.

Additionally, calmness contributes to better management of air consumption and physical exertion, which are critical in emergency situations. It fosters situational awareness, helping the diver to prioritize safety and recognize available resources or escape routes. By maintaining a composed demeanor, the diver can effectively utilize their training and skills to handle the situation, ultimately enhancing their chances of a safe resolution.
