Answer: The distribution of skin temperature throughout the body is not uniform (i.e. lower in the extremities than in the trunk) and it also changes with environmental temperature (i.e. it is higher in summer than in winter).
Explanation: The human body regulates body temperature through a process called thermoregulation, in which the body can maintain its temperature within certain boundaries, even when the surrounding temperature is very different. The core temperature of the body remains steady at around 36.5–37.5 °C (or 97.7–99.5 °F).
