We have probably all felt irritable or grumpy when we felt we needed to eat, a condition many people jokingly call being “hangry.” According to a new study published in the journal PLOS One, being hangry is a real phenomenon. English researchers surveyed 64 adults five times a day at random times for three weeks. They asked each participant how much time had passed since they last ate. They also had each one rate their emotional state as well as their feelings of hunger, irritability, and anger. They observed that hunger was significantly associated with greater anger and irritability and lower pleasure. The researchers believe that the study not only shows that being “hangry” is real but also that our feelings of hunger significantly and negatively affect our emotions.
