What is the main purpose of lifeguard rotation?

The main purpose of lifeguard rotation is to prevent fatigue and maintain vigilance. When lifeguards rotate positions, they allow themselves periods of rest while ensuring that there is always a trained professional actively monitoring the swimmers. This practice is essential for sustaining alertness, as fatigue can lead to decreased response times and impaired decision-making, which are critical in emergency situations. By mitigating fatigue through regular rotations, lifeguards can remain more focused and effective in their role, ultimately enhancing the safety of all patrons in the water.
