Hunger raises anger hormones.. Here are the latest studies

A study, the first of its kind to measure the effect of hunger on anger outside the laboratory, found that the link between appetite and emotions is strong, and that people's hunger levels influence their subjective feelings of irritability and anger.

Most of the previous research on the links between hunger and anger has been done in the lab, but researcher Viren Swami and colleagues from the University of Cambridge asked 64 people in Germany, Austria and other countries to use a phone app to fill out short surveys about their feelings and how long they were hungry five times each day, for 3 weeks.

"The more hungry you are, the more likely you are to feel irritable and angry, and the less pleasure you will feel," Swami said. “It is a powerful and valid effect.”

The study showed that the effect size was large. Hunger pains were associated with 56 percent of the variance in feelings of irritability, for example. "It is more likely that when you feel hungry, the potential negative contextual cues are interpreted as very negative," Swami explained. Such signals can include feeling hot or bumping into people in a crowded place.

When we get angry, we often cry... What are the reasons?

"This may be because low blood sugar triggers the release of hormones such as adrenaline, which triggers the fight-or-flight response, and cortisol, which raises stress levels."
