What are the endpoints of the defined safe margins for body temperature?

• A. 34.4 degrees Celsius and 41.1 degrees Celsius
• B. 34.0 degrees Celsius and 40.0 degrees Celsius
• C. 35.0 degrees Celsius and 37.0 degrees Celsius
• D. 36.0 degrees Celsius and 39.0 degrees Celsius

Answer: (A)

Understanding safe margins for body temperature means knowing the boundaries within which the body's systems operate safely. If the core temperature falls too low, metabolic processes slow and the risk of hypothermia rises; if it rises too high, enzyme activity and brain function can be impaired, increasing the danger of heat-related injury. The defined endpoints—34.4°C on the low end and 41.1°C on the high end—mark these safety boundaries. They correspond to about 93.9°F and 106°F, giving a range that keeps bodily functions within a tolerable limit. Other numbers don’t define the same wide, safe span, and thus aren’t used as the endpoints.
