NPR: Understanding “Sleep Munchies”

From NPR: Sleep Munchies: Why It’s Harder to Resist Snacks When We’re Tired

An excerpt:

There’s lots of evidence that getting too little sleep is associated with overeating and an increased body weight.

The question is, why? Part of the answer seems to be that skimping on sleep can disrupt our circadian rhythms. Lack of sleep can also alter hunger and satiety hormones.

Now, a new study finds evidence that sleep deprivation (getting less than five hours of sleep per night) produces higher peaks of a lipid in our bloodstream known as an endocannabinoid that may make eating more pleasurable.

So, what’s an endocannabinoid? If you look at the word closely, you may already have a clue. The prefix endo means inner, or within. And cannabinoid looks like … you got it: cannabis.

My take: Another good reason to avoid being on call -it could lead to sleep deprivation/weight gain.
