(CNN) — Not getting enough sleep could be the reason for your junk food cravings.
A recent study shows people who were sleep-deprived had bigger appetites.
And they also had a tough time controlling their urges for carbs.
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-occurring cannabis-like substance in the human body triggers cravings for fatty and sugary foods.
And not getting enough sleep makes that worse.
