Question

Here’s something that might make you feel a little better the next time you have a serious case of hanger - you’re not being irrational or unreasonable, it’s just science．

The concept of being ‘hangry’ - angry because you’re hungry - comes up among ScienceAlert staff．But there’s nothing wrong with being hangry - there’s a scientific reason why having low blood sugar can make some people aggressive．

According to a study published earlier this year, blood sugar levels directly related to how married couples were likely to treat each other．Working with 107 couples over three weeks, the researchers, led by psychologist Brad Bushman from the Ohio State University in the US, found that when individuals experienced lower than usual blood sugar levels, they became increasingly aggressive and mean towards their significant others．

This was measured through the use of a good old-fashioned voodoo doll — the volunteers were each given one, along with 51 pins, to represent their spouse-a partner in marriage．Each person’s aggressive impulses（沖動(dòng)）were then measured based on how many pins they stuck into their spouse-dolls every night throughout the experiment．

Aggression, on the other hand, was measured by volunteers blasting（炮轟）their spouse with a loud and unpleasant noise in the headphones they had to wear．

Turns out that the volunteers who experienced the lowest blood sugar levels stuck more pins into their voodoo dolls, and forced louder and longer blasts of noise on their spouses than those who had plenty of glucose(葡萄糖) in their system．

"People are often the most aggressive against the people to whom they are closest — intimate partners,” the researchers concluded．"Intimate partner violence might be partly a result of poor self-control．Self-control of aggressive impulses requires energy, and much of this energy is provided by glucose from the food we eat．"

As Susannah Locke explains at Vox, glucose is the only molecule（分子） that our brains will accept as fuel．This means, quite simply, that when we’re not producing enough glucose, our brains won’t function properly．It also means that we lack the energy we need to maintain self-control, which is why we’re more likely to hit or criticize others suddenly in an uncharacteristic manner when we haven’t eaten in a while．
