Make a Splash with the 2025 Red Cross Lifeguard Practice Test – Dive into Success!

Staying hydrated by drinking plenty of water is crucial for maintaining alertness, especially in hot conditions. When a lifeguard is exposed to high temperatures, their body can become dehydrated, which can lead to fatigue, decreased concentration, and diminished physical performance. Hydration supports cognitive function, helping lifeguards remain vigilant and responsive to any potential emergencies.

While other options like staying in a cooler area during breaks or taking more frequent breaks can provide relief from the heat, they don't directly address the physiological need to maintain hydration. Jumping in the pool might offer temporary relief but is not a recommended practice while on duty, as it could distract the lifeguard from their responsibilities. Thus, regular water intake is the most direct means of enhancing alertness and overall well-being in a hot environment.
