Abstract
Halberg1 and Pittendrigh2 have shown that the organs, glands and tissues of animals have synchronized circadian rhythms that may periodically interact among themselves. These rhythms are self-sustaining oscillations with a period of about 24 h that are synchronized by the light and temperature cycles of the environment. Also, the metabolic activity of animals is usually most nearly normal when these rhythms are synchronized by natural cycles of light and dark and heat and cold.
