What is one major factor that affects a lifeguard's ability to perform rescues?

Fatigue or exhaustion is a significant factor that can impact a lifeguard's ability to perform rescues effectively. Lifeguards are required to maintain high levels of alertness and physical readiness to respond swiftly to emergencies. When fatigue sets in, it can lead to slower reaction times, compromised decision-making skills, and diminished physical strength, all of which are critical when executing a rescue. A lifeguard who is exhausted may struggle to swim with the force needed to reach a distressed swimmer promptly or may not be able to execute necessary maneuvers during the rescue.

While weather conditions, the number of swimmers present, and pool depth can all influence the overall environment and challenges a lifeguard faces, the direct impact of a lifeguard's personal endurance and energy levels is paramount in determining their performance and effectiveness during rescue situations.
