Therefore, an oral temperature of would, strictly speaking, be a normal, healthy temperature in the afternoon but not in the early morning.

Sutherland Simpson and J.J. Galbraith observed that all nocturnal animals and birds whose periods of rest and activity are naturally reversed through habit and not from outside interference experience their highest temperature during the natural period of activity (night) and lowest during the period of rest (day). Those diurnal temperatures can be reversed by reversing their daily routine.', 'lowest at 11 p.m. to 3 a.m', 'In humans, a diurnal variation has been observed dependent on the periods of rest and activity, lowest at 11 p.m. to 3 a.m. and peaking at 10 a.m. to 6 p.m.']}}]}]
