“…Circadian fluctuations are evident in various physiological functions of the human organism: clinical chemical parameters and endocrinological parameters such as concentration of hemoglobin, potassium, iron, adrenaline, noradrenaline, cortisol, and other hormones in blood and serum (Wisser and Breuer, 1981), body temperature (Aschoff, 1955) as well as cognitive functions such as reaction time to sensory cues (Kleitman et al, 1938) and memory tasks of various complexity (Van Eekelen and Kerkhof, 2003). In particular, circadian fluctuations also occur within the sensorimotor system.…”

Making music on a professional level requires a maximum of sensorimotor precision. Chronotype-dependent fluctuations of sensorimotor precision in the course of the day may prove a challenge for musicians because public performances or recordings are usually scheduled at fixed times of the day. We investigated pianists' sensorimotor timing precision in a scale playing task performed in the morning and in the evening. Participants' chronotype was established through the Munich Chrono-Type Questionnaire, where mid-sleep time served as a marker for the individual chronotypes. Twenty-one piano students were included in the study. Timing precision was decomposed into consistent within-trial variability (irregularity) and residual, between-trial variability (instability). The timing patterns of late chronotype pianists were more stable in the evening than in the morning, whereas early chronotype pianists did not show a difference between the two recording timepoints. In sum, the present results indicate that even highly complex sensorimotor tasks such as music playing are affected by interactions between chronotype and the time of day. Thus, even long-term, massed practice of these expert musicians has not been able to wash out circadian fluctuations in performance.

“…The increase of amplitude is mainly due [1,11] to the lowering of night temperatures. Just as in the ease of the heart rate, so also in the case of body temperature, the deepening and broadening of the night-lowering led to a shifting to the right of the morning rise in temperature.…”

“…It has been suggested that social factors may act as Zeitgeber for the maintenance of circadian rhythms of body temperature [Aschoff, 1955] and of the fluctuations in number of certain cellular elements in the blood [Halberg, Engel, Treloar and Gully, 1953] in man, and it is possible that they may play some part in the maintenance of the renal rhythms. The perception of a daily alternation of light and darkness cannot be the only factor involved in the establishment and maintenance of human renal rhythms, for observations on subjects with impaired sight reveal a small number of totally blind subjects who exhibit absolutely normal rhythms [Lobban and Tredre, 1967 b].…”

The daily rhythms of renal excretion of indigenous arctic subjects were recorded under natural conditions during the continuous midsummer daylight (Indians and Eskimos) and in the continuous darkness of midwinter (Indians only). The excretory patterns for water, potassium, sodium and chloride have been compared with those of a group of British control subjects, recorded when they were newly introduced into a summer arctic environment in adult life. In general, the excretory patterns of the arctic subjects contain a high proportion of abnormalities, such that the averaged patterns for the indigenous groups are less well defined than are those for the control group of subjects from a temperate zone. The loss of definition of the rhythms is most marked in the Eskimo subjects, where differences between day and night excretory rates have virtually disappeared. Mathematical analysis of the individual results shows that the relative amplitude of the rhythm of potassium excretion decreases from British controls → summer Indians → winter Indians → summer Eskimos. The differences between control subjects and all indigenous subjects and between Indians and Eskimos are significant, and cannot be accounted for by variations in age, activity pattern or diet. It is suggested that the normal daily alternation of light and darkness in the environment is important not only for the day‐to‐day maintenance of renal diurnal rhythms but also for the initiation and full expression of these rhythms in the early life of the human subject.
