What are the symptoms of heat-related illness to recognize as a lifeguard?

Heavy sweating, weakness, and dizziness are key symptoms of heat-related illness that lifeguards must recognize. These symptoms are indicative of the body's response to overheating, typically seen in conditions such as heat exhaustion. When a person is exposed to high temperatures, the body attempts to cool itself through sweating. If this sweating is excessive, it can lead to dehydration, causing weakness and feelings of dizziness as the body's electrolyte balance is disrupted and blood flow to the brain is affected.

Recognizing these symptoms early is crucial for a lifeguard, as it allows for timely intervention to prevent the situation from escalating into more severe conditions like heat stroke. In cases of heat exhaustion, immediate actions such as providing cool water, moving the affected person to a shaded area, and monitoring their condition can be life-saving.

In contrast, the other options describe symptoms more relevant to different medical conditions. Cold skin and shivering suggest hypothermia rather than heat-related issues. Fever and chills are commonly associated with infections or illnesses, while dry mouth and headache can indicate general dehydration but are not specific indicators of heat-related illness. Understanding these distinctions helps lifeguards provide appropriate care and effectively identify heat-related issues in swimmers and beachgoers.
