What is a common indication of a swimmer in distress?

A common indication of a swimmer in distress is that they may be struggling to keep their head above water. This behavior is often a sign that the swimmer is unable to maintain buoyancy or is experiencing difficulty due to exhaustion, panic, or other factors. In this state, the swimmer's movements can become erratic and uncoordinated as they fight to breathe, making it critical for lifeguards and others nearby to recognize and respond to this situation promptly.

The other scenarios are more indicative of a swimmer being comfortable and safe in the water. For instance, splashing and laughing suggests that a swimmer is enjoying themselves and is not in distress. Similarly, floating on their back generally indicates relaxation and comfort in the water. Swimming vigorously can also signify a swimmer is enjoying recreational activity rather than being in danger. Therefore, recognizing the signs of struggle—such as attempting to keep the head above water—is essential for a timely and effective rescue response.
