What are some effects of heat stress?

Heat stress can significantly affect the body due to elevated temperatures, especially during physical activities such as pesticide application. Dehydration occurs when the body loses more fluids than it takes in, which is common during hot conditions. As dehydration progresses, it can lead to heat exhaustion, characterized by symptoms like heavy sweating, weakness, dizziness, and nausea. In more severe cases, heat stress can escalate to heat stroke, a life-threatening condition where the body temperature rises to dangerous levels, leading to confusion, loss of consciousness, and potentially fatal complications.

Understanding these effects is crucial for anyone working in environments exposed to high temperatures, as it highlights the importance of hydration, regular breaks, and monitoring personal health to prevent severe outcomes during pesticide application and other outdoor activities.
