Which of the following is a sign of a swimmer in distress?

A swimmer in distress often exhibits specific signs that indicate they are struggling to stay afloat or are in a dangerous situation. The indication of a head being low in the water, combined with waving arms, is a clear signal that the individual is unable to keep their head above water and is attempting to signal for help. This posture is a strong indicator of distress, as it shows the swimmer is likely panicking or cannot maneuver effectively in the water.

In contrast, swimming with ease and confidence or making forward progress without difficulty demonstrates that the swimmer is capable and comfortable. Similarly, floating on the back while relaxing represents a state of calm and control, demonstrating that the individual is not in distress. Recognizing these differences is vital for lifeguards to respond appropriately and ensure the safety of individuals in the water.
