What do firefighters need to monitor during their rehabilitation process?

During the rehabilitation process, it is crucial for firefighters to monitor their hydration levels. This is because firefighters engage in physically demanding work that can lead to significant fluid loss through sweat, especially under high-stress conditions and in extreme heat. Dehydration can impair physical performance, decision-making abilities, and overall safety, increasing the risk of heat-related illnesses or other medical emergencies.

Ensuring adequate hydration helps in recovery and maintains optimal physical and cognitive functioning during firefighting tasks. Monitoring hydration levels allows firefighters to replenish fluids appropriately, reducing the risk of exhaustion and facilitating effective recovery between strenuous activities. By focusing on hydration, they can ensure they remain fit for duty throughout their shift.

The other options, while relevant to firefighting safety and operations, do not directly pertain to the immediate physiological needs of the firefighters during their rehabilitation process.
