The reason we crave junk food when sleepy


There's a scientific reason you crave junk food when you don't get enough sleep

(CNN) — Not getting enough sleep could be the reason for junk food cravings.

A study shows people who were sleep-deprived had bigger appetites and they also had a tough time controlling their urges for carbs.

The reason?

According to researchers, when you’re sleep deprived — a hormone called “ghrelin” increases in your body and that leads to hunger.

But few of us wake up craving a salad or carrot sticks.

That’s because researchers also found that a naturally-occuring cannabis-like substance in the human body triggers cravings for fatty and sugary foods.

And not getting enough sleep makes that worse.
