The result is a vicious cycle of psychological and physical stress:rising fear,shallow,ineffective breathing and involuntary stress responses. As the stress rises, the Scuba diver's emotions may exceed his ability to control them, so that he panics, abandoning new or seldom used Bali Scuba dive skills for random, instinctive skills. This will lead to exhaustion and unless a rescue intervenes, an accident, as shown in the Stress Management Chart. Note that physical stress due to overexertion easily sets off this psychological cycle because the Scuba diver experiences air starvation, leading to emotional stress, elevated breathing (stress response), anxiety, etc. If the Scuba diver doesn't recognize what's happening, what starts as a hard swim could end in an irrational, panicked ascent.

Another possible response to high stress occurs when an emergency doesnt happen. If the perceived threat was immediate and specific, when nothing happens the Scuba diver relaxes. However, when the perceived threat is continuous and/or general, the Scuba diver remains stressed - anticipating an emergency that doesn't come - with possible trembling, erratic breathing and high heart rate. This state of anxiety can compromise motor func­tions, control and hold the Scuba diver in a distracted, perceptually narrowed state until the Bali Scuba dive ends or the perceived threat passes. Again, the real hazard may be the Scuba diver's impaired responses while Bali Scuba diving, rather than the perceived threat.
