    Shift workers have lower Testosterone and Pregnenolone

    "Lower levels of serum pregnenolone and total testosterone were found in the shift workers compared to the daytime workers. Variations in pregnenolone levels may have consequences for well-being, and they might produce consequences for the levels of hormones downstream of the steroid hormone...

    Sunlight brightness not needed for circadian rhythm? (lightbulb brightness can be enough?)

    Probably best to assume sunlight brightness is optimal for circadian rhythm still, (faster effects at that brightness?), but studies have shown light from standard lightbulbs give significant effects on circadian rhythm still, especially if around 500 lux which looks to give full effects in...

    Gluten free diet modulates my constipation and ED

    I randomly decided to not eat any wheat. Noticed nothing that day. The next day: No morning grog Morning wood (unusual for me) No daytime sleepiness Pooped 3 times that day Only had to wipe 2 or 3 times Erections are Enzyte-tier and on time My scrotum now hangs my balls. (My scrotum normally...

    DHEA Can Reset The Circadian Clock, Treat Jetlag

    Disruptions in the circadian clock have been shown to directly cause a number of disease including obesity, diabetes, cancer and neurodegenerative diseases like Alzheimer, Parkinson, and even ALS. People working night shifts or engaging in frequent flying across many timezones are the most...

    Vitamin B2 (FAD) (not Light) May Control The Circadian Clock

    Hopefully this won't spur another war on words as the previous discussion on the circadian clock. This study found that the coenzyme FAD (a derivative of riboflavin) control the circadian clock in a light-independent manner. To make the matters even more "metabolic" so to speak, the levels of...

    Taurine Treatment Modulates Circadian Rhythms In Mice Fed A High Fat Diet

    Taurine Treatment Modulates Circadian Rhythms in Mice Fed A High Fat Diet. - PubMed - NCBI Close ties have been made among certain nutrients, obesity, type 2 diabetes and circadian clocks. Among nutrients, taurine has been documented as being effective against obesity and type 2 diabetes...

    Disruption Of The Circadian Clock In Mice Increases Intestinal Permeability

    Disruption of the Circadian Clock in Mice Increases Intestinal Permeability and Promotes Alcohol-Induced Hepatic Pathology and Inflammation Here we report, for the first time, that circadian disorganization causes increased permeability of the intestinal epithelial barrier in mice. Both genetic...

    Daily Magnesium Fluxes Regulate Cellular Timekeeping And Energy Balance(Circadian Clock)

    Daily magnesium fluxes regulate cellular timekeeping and energy balance. - PubMed - NCBI Circadian clocks are fundamental to the biology of most eukaryotes, coordinating behaviour and physiology to resonate with the environmental cycle of day and night through complex networks of...

    Circadian Clock Dysruptions Driven By Adrenal Activity (cortisol)

    If the results of this study translate to humans then taking a little pregnenolone or progesterone (which restrain excessive cortisol release) may allow people to quickly adapt their circadian clock to a new environment as a result of long flights or working in prolonged conditions of artificial...

    Circadian Clock Obeys Metabolism/sugar, Not Light/genes

    This is an excellent study b/c it demonstrates the circadian clock, which is one of the bastions of genetics, is actually controlled by metabolism and, more importantly, by the availability of sugar as a food source. Good and predictable availability of food "stabilizes" the circadian clock as...

    Red Light And Circadian Cycle

    I read the interesting claim that red lights are used for night illumination because they are supposed to be safer in terms of interference on the circadian cycle. Is there any truth to that? What are some interesting implications? They give a bit more explanation:
