Being “hangry” is a real emotional state, a new study confirms.

Researchers in Europe have discovered that feeling hungry really does lead to more anger and irritability. Hangry, or the blending of the words hungry and angry, has become a popular expression in everyday language in recent years. However, researchers note that this is the first study to examine how the phenomenon affects a person’s day-to-day emotional state.

Not only does hunger increase levels of anger and irritability, study authors from Anglia Ruskin University (ARU) and the Karl Landsteiner University of Health Sciences say it also lowers a person’s level of pleasure.
