The word "hangry" - a portmanteau of hungry and angry - was officially added to the Oxford English Dictionary in 2018 according to new research published by Anglia Ruskin University in the U.K. and the Karl Landsteiner University of Health Sciences in Austria, "hanger" is a real emotion, as hunger can be associated with increased anger and irritability. "Many of us are aware that being hungry can influence our emotions, but surprisingly little scientific research has focused on being 'hangry'.” Professor Viren Swami says.
