How does heat exhaustion influence the body temperature?

Heat exhaustion occurs when the body loses excessive fluids and electrolytes due to prolonged exposure to high temperatures, leading to an inability to regulate temperature effectively. This condition typically results in an elevated body temperature, often between 100.4°F (38°C) and 104°F (40°C). Symptoms may include heavy sweating, weakness, dizziness, and nausea, as the body's cooling mechanisms become overwhelmed. If not addressed, heat exhaustion can progress to heat stroke, a more severe condition that poses serious health risks.
