Körpertemperatur-Schwankungen mit besonderer Rücksicht auf den Einfluss, welchen die Umkehrung der täglichen Lebensgewohnheit beim Menschen ausübt

Physiology of the temperature of birds

“…The stimulating effect which food has is absent in this case, so that the rise in temperature is clearly due to muscular activity alone. This effect of activity in wild birds is in harmony with the rise in temperature of man which has been observed as a result of work (Pembrey, 1898;Benedict and Snell, 1902), and also in the domestic fowl (Fere, 1899).…”

The Development of Circadian Rhythms in Infants

“…In the following Fig. 6 we have supplemented the data of Jundell [1] by data from school children, which we determined [12], and by data determined from adults [13]. The shift to the right can be recognized without difficulty if one considers the lowest nighttime body temperature value from which arises a progressive increase toward the morning hours.…”

A study of the fasting metabolism of various breeds of pig. II. Body temperature measurements

“…All these were professional fasters. In human beings generally Benedict and Snell (16) found no reduction nor did Benedict, Horst and Mendel (17) in large rats. Although the majority of these results are negative, those of Eichet, Isenschmid, Tasaka, and Nichita and Iftimesco are notable exceptions, and taken with the present results appear to show that there are some animals, of which the pig is clearly one, in which fasting induces a definite reduction of body temperature.…”
