What is an indication of a distressed swimmer?

A distressed swimmer is typically characterized by their struggle to stay above water, which can manifest as difficulty in maintaining their head above the surface. This indicates that they are experiencing distress, either from exhaustion, panic, or an inability to swim effectively. The swimmer may be making noticeable, desperate movements to keep afloat, such as thrashing or an erratic motion, which differentiates them from someone who is swimming normally or efficiently.

In contrast, a swimmer who is waving their arms may be signaling for help but is not specifically indicating distress from the perspective of swimming ability. Floating on one’s back usually suggests a comfortable and relaxed state rather than a sign of distress. Similarly, a swimmer who is moving through the water with ease is demonstrating confidence and skill, not distress. Therefore, the option that accurately reflects a swimmer in distress is the one describing the struggle to keep their head above water.
