What are signs of possible heat-related illnesses?

Heat-related illnesses can manifest through a variety of symptoms that indicate the body's struggle to regulate temperature in hot conditions. The correct choice includes signs such as excessive sweating, weakness, dizziness, nausea, and confusion.

Excessive sweating is often one of the first signs as the body attempts to cool down. When the body becomes overheated, it can lead to weakness and dizziness due to dehydration and loss of essential electrolytes. Nausea may occur as the body’s response to heat stress. Confusion can arise when body temperature rises to levels that affect brain function, indicating a serious condition like heat stroke or heat exhaustion.

Understanding these symptoms is crucial for lifeguards, as timely recognition and response can prevent escalation into more severe heat-related illnesses, which can be life-threatening.
