Hunger really can make us feel ‘hangry’ – Anglia Ruskin University study shows
New research led by academics from Anglia Ruskin University (ARU) and the Karl Landsteiner University of Health Sciences in Austria has discovered that feeling hungry really can make us “hangry”, with emotions such as anger and irritability strongly linked with hunger.
Published in the journal PLOS One, the study is the first to investigate how hunger affects people’s emotions on a day-to-day level. Hangry, a portmanteau of hungry and angry, is now used in everyday language but the phenomenon has not been widely explored by science outside of laboratory environments.
The researchers recruited 64 adult participants from central Europe, who recorded their levels of hunger and various measures of emotional wellbeing over a 21-day period.
Participants were prompted to report their feelings and their levels of hunger on a smartphone app five times a day, allowing data collection to take place in participants’ everyday environments, such as their workplace and at home.
The results show that hunger is associated with stronger feelings of anger and irritability, as well as lower ratings of pleasure, and the effects were substantial, even after taking into account demographic factors such as age and sex, body mass index, dietary behaviour and individual personality traits.
Hunger was associated with 37 per cent of the variance in irritability, 34 per cent of the variance in anger and 38 per cent of the variance in pleasure recorded by the participants. The research also found that the negative emotions – irritability, anger, and unpleasantness – are caused by both day-to-day fluctuations in hunger, as well as residual levels of hunger measured by averages over the three-week period.
Lead author of the study Viren Swami, professor of social psychology at ARU, said: “Many of us are aware that being hungry can influence our emotions, but surprisingly little scientific research has focused on being ‘hangry’.
“Ours is the first study to examine being ‘hangry’ outside of a lab. By following people in their day-to-day lives, we found that hunger was related to levels of anger, irritability, and pleasure.
“Although our study doesn’t present ways to mitigate negative hunger-induced emotions, research suggests that being able to label an emotion can help people to regulate it, such as by recognising that we feel angry simply because we are hungry. Therefore, greater awareness of being ‘hangry’ could reduce the likelihood that hunger results in negative emotions and behaviours in individuals.”
