In high-heat environments, what should workers monitor frequently?

In high-heat environments, it is crucial for workers to monitor hydration levels frequently. Staying hydrated is essential to prevent heat-related illnesses such as heat exhaustion and heat stroke, which can occur when the body is unable to cool itself effectively. As individuals sweat to cool down, they lose fluids and electrolytes, making it imperative to replenish them regularly.

Monitoring hydration levels allows workers to be proactive in managing their health and well-being in extreme temperatures. This involves drinking water at regular intervals rather than waiting until they feel thirsty, which is often too late to prevent dehydration. Proper hydration helps maintain physical performance and cognitive function, both of which can be significantly impaired due to dehydration in a hot environment. Thus, being attentive to hydration levels is a vital safety measure for workers in high-heat conditions.
