What is recommended for guests who are alert and not nauseous after overheating?

When guests are alert and not nauseous after experiencing overheating, it is advisable to provide them with cool water or a sports drink. This is because rehydration plays a crucial role in recovery from overheating. Cool water or a sports drink not only helps replenish lost fluids but also provides essential electrolytes, which can be depleted during heat exposure.

Heavy meals could place additional strain on the body, making it more challenging to recover from overheating. Cold solids, while potentially refreshing, do not serve the same purpose of hydration and electrolyte replenishment. Cold compresses can provide temporary relief and cool the body, but they do not address the internal hydration needs as effectively as water or sports drinks. Therefore, encouraging the intake of cool water or a sports drink is the most beneficial recommendation in this situation.
