Circadian rhythms and diabetes [PDF]

open access: yesJournal of Diabetes Investigation, 2011
All free‐living organisms are regulated by the 24‐h light and dark cycle produced by Earth’s rotation. In mammals, circadian rhythms are indispensble for the regulation of physiological and biochemical processes in the body. In 1972, the suprachiasmatic nucleus was shown to be required for daily rhythms in animal behavior1.
