Studies show that hunger can actually make people “homeless.”

Some studies have shown that hunger is closely associated with feelings of anger and irritability, leading to a feeling known to many as a hangover: verbal hunger and anger.

The study, led by academics from Anglia Ruskin University (ARU) in the UK and Karl Landsteiner University of Health Sciences in Austria, also found that hunger was associated with lower levels of pleasure.

Viren Swamy, professor of social psychology at ARU and lead author, said:

“Our study is the first to investigate ‘hunger’ outside of the laboratory.

“By following people in our daily lives, we found that hunger was associated with levels of anger, irritation and joy.

Our research doesn’t suggest ways to mitigate negative emotions caused by hunger, but studies can label emotions, for example, just because we’re hungry. By acknowledging the feeling of anger, it suggests that people can help adjust it.

“Increasing awareness of being ‘hungry’ may therefore reduce the likelihood that hunger will elicit negative emotions and behaviors in a person.”

The researchers recruited 64 people from Central Europe who recorded various measurements of their levels of hunger and emotional well-being over a 21-day period.

They reported their feelings and hunger levels on a smartphone app five times a day.

Hunger is associated with strong emotions of anger and irritation, and a low rating of joy, according to the findings.

This study suggests that the effect was significant even after accounting for factors such as age, gender, obesity rate, dietary behavior, and personality.

He also found that negative emotions (stimulation, anger, unpleasant sensations) were caused by both daily fluctuations in hunger and residual levels of hunger.

The findings are published in the journal Plos One.
