What is a common sign that a diver is experiencing physical fatigue?

Physical fatigue in divers can manifest through various physical signs that indicate the body is struggling to perform optimally underwater. Shaky hands and muscle cramps are clear indicators of fatigue. The muscles can become overworked, leading to spasms or cramps, while shakiness in the hands may signify a lack of strength or endurance. This combination signals that the diver’s body is either tired or not receiving enough oxygen to sustain normal function.

Other signs of physical fatigue might include increased dependency on buoyancy control or difficulty maintaining proper breathing patterns, but shaky hands and muscle cramps are more direct cues that a diver needs to rest and may be approaching their limits. Recognizing these signs is crucial for ensuring safety during dives.
