How does heat exhaustion influence the body temperature?

Heat exhaustion does not significantly elevate the body's core temperature. While heat exhaustion can lead to an increase in body temperature, it typically remains below the levels considered dangerously high. It occurs when the body loses excessive fluids and electrolytes due to prolonged exposure to high temperatures or strenuous physical activity. Instead of experiencing extremely high body temperatures, individuals with heat exhaustion exhibit symptoms such as profuse sweating, weakness, dizziness, muscle cramps, nausea, and fatigue.

Body temperature regulation is disrupted when the body's natural cooling mechanisms are overwhelmed by excessive heat. Normally, the body cools down by sweating and releasing heat through the skin. However, in extreme conditions, the body may not be able to release heat quickly enough, leading to an increase in body temperature.

Heat exhaustion is a milder form of heat-related illness compared to heatstroke. Heatstroke occurs when the body's core temperature reaches dangerously high levels, usually above 40°C (104°F). Heatstroke is a medical emergency and requires prompt treatment to prevent serious complications and potential organ damage.
