How often should a lifeguard change posture to stay alert during their duty?

Changing posture every 5 minutes is an effective strategy for lifeguards to maintain alertness while on duty. This interval allows lifeguards to shift their body position, helping to reduce fatigue and improve circulation. By periodically adjusting their posture, lifeguards can also maintain better focus on their surroundings, which is critical for spotting any potential hazards or emergencies in the water.

Regularly repositioning oneself prevents the onset of monotony and helps maintain mental engagement, reducing the risk of distraction. While different facilities may have specific guidelines, the general recommendation to change posture frequently supports both physical comfort and heightened vigilance, ensuring lifeguards are always ready to respond efficiently to any situation.
