Lifeguards can reduce fatigue during their shift by rotating from station to station. Rotation is beneficial because it allows lifeguards to engage different muscle groups and reduce the strain of remaining in one position for an extended period. This change of scenery and activity helps to maintain alertness and vigilance, which are critical for effective monitoring of the pool or beach area. Different stations may also have varying demands, which can help alleviate the physical and mental monotony that contributes to fatigue.

On the other hand, remaining seated while watching the pool can lead to stiffness and decreased alertness over time. Drinking caffeinated beverages may provide a temporary boost, but it does not address the underlying physical fatigue and can lead to crashes later on. Taking breaks away from the post is important for rest but, depending on the duration and timing of those breaks, it might not be as effective in maintaining overall alertness and energy levels throughout the shift as rotation would be.
