The circadian rhythm of body temperature was investigated in 225 students divided into morning, evening and intermediate types through the Ostberg's questionnaire, as modified in our laboratory. Body temperature exhibited circadian variations in 77% of subjects, but no differences between morning and evening type crest phases were found. Further studies are in progerss in order to detect differences, if any, of other biological parameters between morning and evening type subjects.
