The portmanteau “hangry” — hungry + angry — has often been seen, heard, and talked about. In recent years, more and more people have been using the word to describe the anger that they feel when they haven’t been able to eat.

But is there a physiological reason for this anger? Do hunger pains really affect mood negatively? And what can we do to stop feeling hangry?
