Snacking While Sleepy Is Like Getting The Munchies

Now a new study on sleep deprivation and cravings, published in the journal Sleep, hints at yet another reason for those fatigue-linked food cravings: The sleepier you are, the higher your levels of endocannabinoids, the natural compounds your body produces to help regulate appetite by enhancing the “hedonic,” or pleasurable, aspects of eating in your brain. But the participants who had just completed a restricted sleep schedule couldn’t stop eating, despite the fact that they had just consumed most of their daily calories in one sitting at the buffet lunch. This was also surprising, given that the restricted sleep group had snacked consistently between lunch and dinner, but the extra food doesn’t seem to have had an effect on their hearty appetites for dinner. The rising level of endocannabinoids, as well as their late peak and extended peak hours, may be the reason why participants who had emerged from the restricted sleep schedule ate so much more food than they did after emerging from the normal sleep schedule.
