Gradual Narcosis Onset — Narcosis may develop slowly, making self-assessment unreliable.
Task Fixation at Depth — Cognitive narrowing at depth can reduce awareness of time and ascent rate.
Increased Gas Density Breathing Load — Higher gas density at depth increases work of breathing.
Remote Silt Disturbance — Silt can be disturbed metres away from the source.
Rapid Stress Escalation — Stress can increase sharply when visibility or navigation degrades.
High Cognitive Load Navigation — Complex passages increase mental workload even on a line.
