Simplified control circuit of human thermoregulation.

The average difference between oral and axillary temperatures of Indian children aged 6–12 was found to be only 0.1 °C (standard deviation 0.2 °C), [51] and the mean difference in Maltese children aged 4–14 between oral and axillary temperature was 0.56 °C, while the mean difference between rectal and axillary temperature for children ...
A higher ratio of body surface area (proportional to heat loss) to body volume (proportional to heat production) A higher proportional surface area of the head; A low amount of musculature and the inability to shiver; A lack of thermal insulation, e.g., subcutaneous fat and fine body hair (especially in prematurely born children)
Active heating and cooling uses an artificial heat source or sink to heat or remove excess heat from the diver. A diver can be kept in comfort and thermal equilibrium in a tubesuit garment while immersed in water from 10 to 40 °C (50 to 104 °F), using a flow of water at 30 °C (86 °F).

An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature. [2]
