Study: Feeling Hungry correlated to anger, irritability

Washington [US], July 10 (ANI): According to a new research, feelings of irritation and anger are significantly correlated with hunger, and being hungry might actually make us "hangry."
Hangry, a portmanteau of hungry and angry, is widely used in everyday language but the phenomenon has not been widely explored by science outside of laboratory environments.
The new study, led by academics from Anglia Ruskin University (ARU) in the UK and the Karl Landsteiner University of Health Sciences in Austria, found that hunger is associated with greater levels of anger and irritability, as well as lower levels of pleasure.
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% of the variance in irritability, 34% of the variance in anger and 38% 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 Anglia Ruskin University (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."
The fieldwork was carried out by Stefan Stieger, Professor of Psychology at Karl Landsteiner University of Health Sciences. Professor Stieger said: "This 'hangry' effect hasn't been analysed in detail, so we chose a field-based approach where participants were invited to respond to prompts to complete brief surveys on an app. They were sent these prompts five times a day on semi-random occasions over a three-week period.
"This allowed us to generate intensive longitudinal data in a manner not possible with traditional laboratory-based research. Although this approach requires a great deal of effort -- not only for participants but also for researchers in designing such studies -- the results provide a high degree of generalisability compared to laboratory studies, giving us a much more complete picture of how people experience the emotional outcomes of hunger in their everyday lives."
