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

A common sign that a swimmer may be in distress is struggling to keep their head above water. This behavior indicates that the individual is having difficulty, which could be due to fatigue, panic, or a medical emergency. When a swimmer is unable to maintain their position above the water, it signals immediate danger and the need for assistance.

Waving and calling for help may suggest distress but can sometimes be associated with someone in a managed situation. Floating peacefully on their back and swimming towards the side calmly indicate that the swimmer is likely fine and capable of handling themselves, exhibiting relaxation and control over their situation. Understanding these signs is crucial for lifeguards to identify those who actually need help and to respond appropriately.
