Which of the following factors is NOT listed as affecting body temperature?

• A. Circadian rhythms
• B. Age and gender
• C. Physical activity
• D. Dietary habits

Answer: (D)

The main concept is how body temperature is regulated by the body’s internal clock and energy use. Body temperature varies with circadian rhythms, tends to shift with age and hormonal differences between sexes, and rises with physical activity as muscles generate heat. These are the factors commonly recognized as influencing normal body temperature. Dietary habits, while meal processing does produce some heat, have only a small, temporary effect and aren’t considered a primary determinant of daily body temperature regulation. That’s why dietary habits aren’t listed as affecting body temperature in standard discussions.
