Course Outline

You can experience overexertion by swimming against a current for long distances or carrying excessive weight. You may feel tired, short of breath, and weak. You may also have a tendency for your muscles to cramp and for you to feel panicky. What should you do?

Stop, breathe, and think about the situation.

To counteract the results of overexertion, work out a rational approach and implement it. For example, overexertion at the surface requires you to establish buoyancy, rest, catch your breath, signal for help, and move slowly to the boat or shore. If overexertion occurs underwater, stop, breathe, and think. And do not neglect to signal that you have a problem to your buddy or dive professional.
