Sleeping Off The Munchies

By Staff Reports

(Victor Valley)– From the U.S. Department of Health and Human Services, I’m Ira Dreyfuss with HHS HealthBeat.

Feeling tired and feeling hungry seem to go together, and a researcher at the University of Chicago has an idea why. Erin Hanlon saw this in nine people who spent 13 nights in a sleep lab, gave blood for analysis, and ate a controlled number of calories.

Hanlon examined a chemical called 2-AG, which is part of a system that has a role in enjoyment, such as enjoying eating. She says that, when people were allowed less sleep, their levels of 2-AG were higher in mid-afternoon – as in mid-afternoon snack time.

So she says:

“Individuals need to think of adequate sleep as an important aspect of maintaining good health, and not just as a byproduct of the day.”

The study presented at a meeting of The Endocrine Society was supported by the National Institutes of Health.
