CIRCADIAN RHYTHM

Below are articles you may find of interest. For more information I have a page specifically dedicated to the explanation of circadian rhythms. 

Two-minute explainer: Circadian rhythms   LUX Your Independent Guide To Lighting                                                                                                             Circadian rhythms describe patterns of behaviour that exist in most things that live on this planet of ours. It’s not just the higher mammals that exhibit these patterns

Insecticides Bind Melatonin Receptors, Altering Circadian Rhythms  by Ellen Goldbaum                                                                                                      Synthetic chemicals commonly found in insecticides and garden products bind to the receptors that govern our biological clocks, UB researchers have found. The research suggests that exposure to these insecticides adversely affects melatonin receptor signaling, creating a higher risk for metabolic diseases such as diabetes.
