What are the symptoms of heat distress?

Heat distress encompasses various symptoms that can indicate the body's struggle to cool itself in high-temperature conditions. Among the options provided, symptoms like cool, clammy skin and dizziness are indeed characteristic of heat exhaustion, which is a form of heat distress.

When the body becomes overheated, it can lead to moisture loss and results in sweating, which typically cools the skin. However, if sweating is excessive or the body can no longer compensate for the heat, it may condition the skin to feel cool and clammy despite the underlying issue of overheating. Dizziness can occur as a result of dehydration and blood flow changes, which also reflects the body's inability to maintain proper homeostatic functions during heat exposure.

For a comprehensive understanding, while other symptoms such as high body temperature, fatigue, rapid pulse, confusion, severe headache, and thirst also signal heat distress, they predominantly specify an evolving condition rather than the initial signs represented in the correct choice. It's essential to recognize these early signs like cool, clammy skin and dizziness which indicate immediate attention to prevent progression to more severe heat-related illnesses.
