Which of the following is NOT a sign or symptom of diver stress?

Excessive clarity of thought is not a sign or symptom of diver stress. In stressful situations, especially underwater, divers may experience confusion, panic, or cognitive impairment as their stress levels rise. This can lead to poor decision-making and difficulty focusing on the situation at hand. In contrast, a state of clarity often indicates that an individual is functioning well mentally, which is the opposite of what typically occurs under stress.

Other signs of diver stress include rapid movements, heavy breathing, and unusual behavior or emotions. Rapid movements might reflect anxiety or discomfort, heavy breathing can indicate stress or panic, and unusual behaviors or emotions may signal an inability to cope with the stress of the dive environment. Recognizing these signs is crucial for maintaining safety and wellbeing while diving.
