A swimmer in trouble often displays distinct physical signs that indicate they are struggling. Frequent head movement and struggling arms are key indicators of distress in water. When a swimmer is in trouble, they might continuously lift their head out of the water to breathe and use erratic or frantic movements with their arms, which indicates they may be having difficulty staying afloat. This kind of behavior contrasts sharply with signs of a competent swimmer, who would typically exhibit calm and controlled movements.

In comparison, calm swimming and smooth strokes represent a swimmer who is proficient and comfortable in the water. Laughing and playing with friends suggests that swimmers are enjoying themselves and not in distress. Waving to friends can also indicate a relaxed state, as it typically does not require strenuous physical effort. Recognizing the signs of a swimmer in distress is crucial for lifeguards, as it allows them to respond quickly and effectively to prevent potential drowning.
