Not getting enough good sleep may raise the risk of diabetes


An intriguing follow-up from the ongoing terrific Nurses’ Health Study has determined that nurses with low levels of melatonin, that hormone we produce at night during sleep, have a significantly higher (over double) the risk of developing Type 2 diabetes compared to women with higher levels of melatonin.

That raises the very interesting possibility – which this study was not designed to look for – that not getting enough sleep at night (that is, by not allowing normal levels of melatonin to be released) may lead to changes that result in Type 2 diabetes, and hence all its complications – amputations, blindness, cardiovascular disease, and on and on - as well.

One conclusion we should avoid as yet, though, namely that taking melatonin supplements can counteract that higher propensity to diabetes that’s associated with less sleep.

Supplements never work as well as the real thing, and there’s no reason to believe that this situation will turn out any differently.

Anyway, what better preventive therapy to suggest than to get  more sleep?
