To Sleep, Perchance to Eat Cheese.
A paper on sleep and light in the early edition of PNAS has garnered some mainstream media attention, here's The Economist's article about it. Basically, when they added light at night to the environment, mice got fat and had increased glucose intolerance. Interestingly, the effect was the same whether the night light was bright or dim, although as The Economist points out, mice are nocturnal and normally eat at night so this might screw them up much worse than humans.
The importance of sleep (and darkness) has been discussed a lot in the paleosphere, Stephan recently did a post on it and of course Mark Sisson has touched on it several times (is there anything he hasn't?). I recently bought a bunch of candles to use in the evenings, the candles lasted 3 days and I didn't notice any difference in sleep and that was the end of my little experiment - ok so I didn't exactly give it the old college try (or rather I gave it Calvin's father's version). Maybe if I could find some cheap bulk candles I would give it another shot.
