Ever felt ‘hangry’? Here’s why-

Did you know that a research study has discovered that feeling hungry can actually make us “hangry,” the phenomenon when people become angry when hungry.

We are already aware that being hungry can influence our emotions, but there is little scientific research on being ‘hangry’. However, findings from the Anglia Ruskin University (ARU), UK and the Karl Landsteiner University of Health Sciences, Austria, show that hunger is associated with increased anger and irritability. Interestingly researchers found that this hunger-induced behavioral change can be reversed by re-feeding and is caused by intestinal cells and neurons communicating and producing behavioral changes.
