You know that feeling: You're waiting for your friends to arrive for brunch, but they're running late as always. You haven't eaten a thing all day — you haven't even had coffee. Your stomach growls as you stare longingly at the hostess. By the time your friends arrive, you're snappy and annoyed.
You, my friend, are hangry — and researchers agree, it's a real feeling, and possibly a survival mechanism, CNN reported.
First things first: food sends nutrients right to our bloodstream, and is used by our organs and for energy by our body.
According to Simon Oxenham in his blog New Scientist, low blood sugar can cause the stress-related hormones, such as cortisol and adrenaline, to be released in some people. Also released is neuropeptide Y, a chemical that can make people act more aggressive to others.
To illustrate this, Oxenham cites a 2014 study in which married couples either stuck a pin in a voodoo doll of their spouse and played a game that resulted in the losing spouse getting a loud blast of sound in their ear through headphones. As people's blood glucose levels dropped, they became less merciful towards their partner.
Another theory is that lack of energy to the pre-frontal cortex to the brain, which controls our self-control, turns us aggressive, The Huffington Post reported.
Although more research needs to be done on the topic, one thing is for sure: don't make big decisions while hungry.
