Hangry

It was my first trip to Seattle. I was, some would say, insufferable.

Upon arrival, I found grilled fish, steak, salads without croutons. Keto in a new city requires strategy. I had been on the diet for two years. My body ran on fat and protein. I knew how to navigate a menu.

An impromptu adventure on day three broke the pattern. Hunger snuck up on me in a foreign place. A pasta bar. A bakery. We walked from one restaurant to the next and every menu was a wall. Rice bowls. Sandwiches. Sugary desserts. Three restaurants. Nothing I could eat.

I was vicious. Short with everyone. Irritated by the noise. Furious at my travel companion for suggesting we just walk and see what we find.

The impressive bridge beside us went unnoticed. An ice cream shop beckoned from across the street. I kept walking. The rain was relentless. The streets crowded. Every inconvenience amplified. I wanted to go home. To my controlled pantry. My safe fridge.

An hour later, standing over a plate of grilled chicken, the growling stopped. Peace arrived with a full stomach. The rain had not changed. The sidewalks were still packed. Nothing in Seattle was different. Everything in me was.

How often does hunger make you angry?

Interoception is the brain's ability to read signals from inside the body. Heartbeat, temperature, blood sugar, muscle tension. A constant stream of data from organs and systems, interpreted in real time. When interoception works well, you notice hunger as hunger. Fatigue as fatigue. Anxiety as a tight chest. When it fails, the signal still arrives. But the label is wrong.

Lisa Feldman Barrett's theory of constructed emotion proposes that the brain does not detect emotions. It constructs them.

Your body sends raw data, pleasant or unpleasant, calm or activated, and the brain selects the nearest available concept to explain it. The concept depends entirely on context. This is why the same racing heart feels like excitement at a concert and panic in a hospital. Identical signals. Different names. The body does not change. Context does.

In 1962, Schachter and Singer injected participants with epinephrine, which mimics the body's arousal response. Some were told what to expect. Others were not. The uninformed group, unable to explain why their heart was pounding, adopted whatever emotion the room suggested. A cheerful confederate made them euphoric. An angry one made them hostile. The environment wrote the label.

Decades later, researchers at the University of North Carolina tested the same principle with hunger. Hungry participants placed in a frustrating situation reported significantly more anger, contempt, and stress than those who had eaten. But here is the finding that matters: the effect vanished when participants recognised they were hungry. The moment awareness interrupted the process, the emotional amplification disappeared. The mislabel required ignorance to survive.

The body cannot say "I need glucose." It can only say "something is wrong." The brain scans the room and decides what.

A 2025 review in the Annual Review of Psychology found that people with stronger interoceptive awareness experience emotions with more precision and regulate them more effectively. Those who struggle to read the body's signals are more vulnerable to anxiety, depression, and emotional overwhelm. The pattern scales beyond hunger. Sleep deprivation becomes irritability. Dehydration becomes fog. Loneliness becomes something that feels like boredom.

But precision is not the deepest problem. Barrett calls the deepest problem affective realism. We do not experience emotions as interpretations. We experience them as perceptions. The anger does not feel like a guess about the world. It feels like an accurate reading of it. The label does not feel applied. It feels discovered.

Which means the moment your brain names the feeling, the feeling stops being a feeling. It becomes a fact about the room you are standing in.

A mislabelled emotion does not wander around confused. It does not stay uncertain. It looks for proof. Minor friction becomes evidence. And because the evidence is real, you never question the conclusion.

The menus lacked options. My companion's suggestion to walk was unhelpful. The streets were crowded. I was not inventing anything. I was making it fit.

The brain does not just name a feeling wrong. It builds a world around that name. Within minutes, there are reasons. Then patterns. Then a verdict. My body needed protein. My mind knew something was wrong and built a city that deserved my contempt.

Sadness does this too. It finds loss in neutral rooms. Anxiety finds threat in safe ones. Anger finds fault in blameless people. And every piece of evidence makes the feeling more certain. More justified. More yours.

We think unreliable emotions are the ones that feel like doubt. "Did I talk too much?" "Was that awkward?" "Did I miss something?" We distrust the feelings we cannot name.

It is the opposite.

Uncertain emotions are still open. They have not found proof yet. But the emotions you are sure about move through life as a closed verdict. Just a body in need. A brain looking for someone to blame.

Your most certain emotions are often the least reliable.
