Sometimes they are due to work exigencies (jet pilots and crew in international travels, night guardians, nurses, the list is long), therefore human life style modifications in our modern society could be produced by a broad environment manipulation (not natural one, but produced by human beings), and become a risk factor for several disorders. There is an interesting fact, that has been reported in scientifically literature. Dietary Reference Intakes (DRIs) developed by the Institute of Medicine (IOM) of the National Academy of Sciences, recommends for pregnant women: 1300 to 1000 mg daily Calcium intake for adolescents and young women respectively. Apart of the importance in healthy bone metabolism, it has been described also diminishing risk for preeclampsia occurrence (by some authors), but this Ca ingestion is not easy to attain, even in healthy and economically sufficient populations, Nevertheless, it was observed in other reports, that in many countries the low Ca ingestion did not badly influenced blood pressure values during pregnancy. Therefore, couldn’t be the daylight influence, taking into account also the seasonal factor combined with latitude a cause of this opposed results?

I wonder how much we are changing human circadian rhythms by leaving lights on for as long as we do. Lots of people have very strange sleeping habits... That sounds interesting too, Marta.

Right now I have in mind metabolism of certain components.
