Which statement about heat stress is true?

Heat stress is a serious condition that can arise from exposure to high temperatures, particularly during strenuous work activities. In the context of heatstroke, one of the prominent symptoms is a lack of sweating. This occurs because the body’s thermoregulation mechanisms begin to fail as it overheats; the body is no longer able to cool itself down effectively. When an individual is experiencing heatstroke, their body temperature can rise to dangerous levels, and the inability to sweat is a significant indicator of this state.

Understanding this symptom is critical for ensuring the safety of individuals working in environments where high temperatures and physical exertion are common, such as agricultural settings where pesticides are handled. Recognizing the signs of heat stress, including the lack of sweating, can help in taking appropriate measures to cool down the body and prevent further health complications.
