What is a common sign that a swimmer may be in distress?

A common sign that a swimmer may be in distress is splashing uncharacteristically. This behavior often indicates that the swimmer is struggling to stay above water or is in a state of panic. Unlike normal swimming, frantic or excessive splashing can mean that the swimmer is not able to keep themselves afloat effectively, which is a clear signal for lifeguards and others to recognize potential trouble.

Observing a swimmer who is splashing more than usual prompts immediate attention because it can lead to a higher risk of drowning if assistance is not rendered quickly. Recognizing this sign allows lifeguards to act promptly and intervene before the situation escalates.

In contrast, waving to attract attention may not necessarily mean the swimmer is in distress; it could simply be a way of saying hello or getting someone's attention for a different reason. Additionally, a swimmer attempting a normal stroke may indicate that they are fine, and submerging without struggle could also suggest that they are diving or swimming underwater intentionally, which doesn’t imply distress. Thus, uncharacteristic splashing is a distinct and critical warning sign of swimmers in trouble.
