All of the following are factors affecting body temperature EXCEPT?

Height is not considered a direct factor affecting body temperature regulation. Body temperature is influenced by several physiological and environmental factors, but height itself does not play a significant role in the body's ability to maintain a stable temperature.

Metabolism directly impacts body temperature because the rate of metabolic processes generates heat; individuals with higher metabolic rates typically have higher body temperatures. Physical activity also increases body temperature due to the heat generated by muscle contractions during exercise. Age influences body temperature as well, with newborns and older adults often having different temperature regulation mechanisms compared to the general adult population.

Understanding these distinctions helps clarify that while metabolism, physical activity, and age all significantly affect body temperature, height does not inherently alter temperature regulation in the same way.
