When you are hungry, you are more likely to struggle with negative feelings. This is a finding that has already entered normal usage in English with the term “hangry”.
The word is a mix of “hungry” and “angry”. But researchers led by Viruses Swami from the British Anglia Ruskin University (ARU) in Cambridge have now been able to prove outside of laboratory conditions that this connection actually exists.
They evaluated the information provided by more than 60 adult volunteers who were asked five times a day via app for a period of 21 days about their feelings of hunger and emotional states such as anger, irritability and pleasure. It turned out that there is a clear connection between the feeling of hunger and negative feelings. The study was published in the journal PLOS ONE.
It is not yet clear where exactly the reason for the connection lies. One possible approach assumes that our brain is no longer able to control emotions to the same extent when blood sugar drops, explained the senior scientist Swami in an interview with the German Press Agency.
Another suggests that when we are hungry we react differently to external factors and find them more disturbing than after a meal. “It’s probably a complicated combination of both,” Swami said. However, he assumes that psychological factors play a greater role than blood sugar levels, whose influence in this context has been questioned by various studies.
As a practical benefit, Swami sees the fact that one can classify one’s feelings better if one is aware of the connection. “When I’m angry, I have to look for the source of this anger,” says the scientist. But if he is “hangry”, then it is enough to eat something.
