Nettetthat humans generally live at thermoneutral temperatures, which minimises their energy demands, and maximises thermal comfort. It was then noted that 21 C lies well below the thermoneutral zone of the mouse, and that their thermoneutral zone is around 30 C. It was therefore postulated that mice should not be housed at 21 C, but NettetThe mouse's body temperature stays close to 37 degrees Celsius across a range of temperatures approximately 5 degrees Celsius to 42 degrees celsius, ...
