I think about it most when I’m getting the least of it. Anyway, very good piece in the nytimes about relationship between diet and sleep. I know that on nights when I get 6hrs of spotty sleep, it is very difficult to say no to the Dunkin’ Donuts drive thru. 

Per several of the studies mentioned in this article, that’s because insufficient sleep increases ghrelin, the hormone that makes you hungry. It’s a viscous cycle though because the more crap you eat, the worse your sleep (and the more crap you want to eat).

The takeaway is that diet and sleep are entwined. Improving one can help you improve the other and vice versa, creating a positive cycle where they perpetuate one another, said Dr. Susan Redline, a senior physician at the Brigham and Women’s Hospital and a professor of sleep medicine at Harvard Medical School who studies diet and sleep disorders.
