What are common symptoms of heat stress?

Fatigue, dizziness, and headache are well-recognized symptoms of heat stress. When the body is exposed to high temperatures, it struggles to regulate its internal temperature. This can lead to dehydration, electrolyte imbalances, and an overall decrease in physical and mental performance. Fatigue occurs as the body expends energy trying to cool itself down, while dizziness may result from reduced blood flow or dehydration. Headaches can arise from dehydration and overheating, indicating that the body's systems are under stress. Recognizing these symptoms is crucial for early intervention and prevention of more severe heat-related illnesses.

The other options highlight symptoms that are not typically associated with heat stress, focusing instead on responses unrelated to heat exposure.
