Ray outlines the 24-hour circadian rhythm that affects all animals´ sleeping and feeding patterns, brain wave activity, hormone production and other biological activities vital to their health and well-being. Melatonin, a hormone produced predominantly at night in the pineal gland, plays an important role in regulating our body clock. Ray discusses the 2006 finding of the National Research Council (NRC) of the National Academies of Science that fluoride is likely to reduce melatonin production and have other effects on normal pineal function. He identifies the potential adverse health impacts of inhibiting or suppressing melatonin production by agents such as fluoride. Ray presents a personal perspective and is not speaking on behalf of The University of Sydney.
