Final answer:
Heat stress is a serious condition where the body cannot cool itself adequately, potentially leading to heat stroke with severe symptoms.
Explanation:
Heat stress occurs when the body is unable to cool itself sufficiently, leading to serious conditions like heat stroke. Heat stroke is a life-threatening situation where the body temperature exceeds 104°F, resulting in symptoms such as dry skin, confusion, seizures, and even unconsciousness.
Dehydration is a significant factor in heat-related illnesses; it hampers sweat production and impairs body cooling mechanisms, leading to conditions like heat exhaustion and ultimately heat stroke.
