Emphasis mine:
“The body is very adept at maintaining temperature within a narrow and safe range, despite occasional huge variations in the room temperature.
But some bodies are more efficient than others. Even bodies of the same height and weight may differ dramatically in the ability to maintain body temperature.
Humans also differ in their preferred room temperature. Some like it warmer, some cooler. This is called thermal comfort. Thermal comfort is not merely physical, but psychological too. In one’s choice of preferred temperature, besides psychology, other personal factors come into the equation. Two of these are clothing levels (their insulation value) and activity level (their effect on body metabolism).”
