The significance of circadian rhythms and dysrhythmias in critical illness
2017
Journal of the Intensive Care Society
Many physiological and cellular processes cycle with time, with the period between one peak and the next being roughly equal to 24 h. These circadian rhythms underlie 'permissive homeostasis', whereby anticipation of periods of increased energy demand or stress may enhance the function of individual cells, organ systems or whole organisms.
