The body's natural clock and metabolism are more closely linked than originally thought, according to a recently released UC Irvine study.
Natural body functions, such as hormone secretion, correlate with the 24-hour light/dark cycle, researchers say.
Now UCI researchers think metabolism may join the ranks of other bodily functions that act in a cyclical manner following the body's internal clock.
Mice used in the study were kept in 12 hours of light and darkness, with tissue samples taken every six hours. The mice revealed periods of greater activity in certain metabolites — chemicals created by metabolism essential for cell health and growth — according to the university.
