TUCSON -

A new University of Arizona study finds a link between sleep loss and junk food cravings. 

A nationwide phone-based survey was conducted with 3,105 adults from 23 United States metropolitan areas.

The participants were asked a series of questions about sleep quality, existing health problems and if they often had a nighttime snack.

The study stated about 60 percent of participants reported that they have nighttime snacks regulary. 

While two thirds of people said the lack of sleep had them crave more junk food. 

Junk food cravings were associated with double the increase in likelihood of nighttime snacking and researchers found that snacking was associated with an increased risk for diabetes.

When it came to poor sleep patterns, researchers saw that as a major predictor of junk food cravings and participants with poor sleep patterns had a more likely chance for obesity, diabetes, and other health problems.

University of Arizona Professor Michael Grandner said that this study may represent that sleep helps regulate metabolism. 

Sleep and wakefulness disorders affects about 15-20 percent of adults in the U.S., according to the U.S. Department of Health and Human Services.
