What are the signs of a distressed swimmer?

The signs of a distressed swimmer include struggling to keep their head above water, waving, or calling for help. This behavior indicates that the swimmer is unable to maintain a safe position and is actively seeking assistance. Observing a swimmer who is in distress often reveals characteristics such as their inability to wave effectively—typically using only their arms while attempting to keep their head above water, making it difficult for them to signal for help while managing their breathing and buoyancy.

In contrast, the other choices present behaviors that do not indicate distress. For example, swimming calmly and waving suggests the swimmer is safe and is either greeting someone or enjoying their swim. Sinking slowly while splashing might indicate panic, but it isn't the definitive behavior signifying distress as effectively as the active struggle for life positions described. Finally, floating on their back and relaxing clearly shows that the individual is safe and not in distress, as they are in a stable position and able to rest without concern.
