What is a common sign of a swimmer in distress?

A common sign of a swimmer in distress is struggling to keep their head above water. This behavior indicates that the individual is experiencing difficulty, which may stem from exhaustion, a medical emergency, or a loss of buoyancy. When a swimmer is in distress, they may exhibit signs of panic, such as flailing arms or sporadic movements, as they attempt to breathe while fighting to stay above the surface.

In contrast, swimming vigorously with ease or floating calmly on their back typically suggests that the swimmer is in control and proficient in their abilities. Similarly, socializing with other swimmers indicates a relaxed state rather than one of distress. Understanding these signs is essential for lifeguards and those involved in water safety, as recognizing distress early can lead to prompt intervention and potentially save lives.
