What signs might indicate a swimmer is becoming fatigued?

A swimmer showing signs of fatigue may exhibit behavior that suggests they are having difficulty remaining afloat or controlling their movements. When a person is becoming tired, their physical condition can deteriorate, leading to erratic movements such as splashing or frantic paddling as they attempt to keep their head above water. This behavior is a clear indicator that the swimmer may require assistance, as it can signify that they are unable to maintain the necessary energy and control to swim safely.

In contrast, calm and steady movements are typically associated with a swimmer who is not fatigued and is swimming effectively. Exceeding their usual swimming speed can often be a result of adrenaline or urgency, rather than an indication of fatigue. Lastly, persistent smiles and laughter tend to reflect comfort and enjoyment in the water, suggesting that the swimmer is not struggling. Identifying these subtle cues is crucial for lifeguards in ensuring the safety of all swimmers in their care.
