Where do we feel emotions in the body? A well-known study from Aalto University in Finland suggests that most people place them in fairly predictable spots. Anger and fear light up the chest and arms, happiness spreads warmth across almost the whole body, and sadness and depression come with a feeling of heaviness or emptiness in the limbs. The colourful "heat maps" from this research, published in 2014, remain among the most shared images in emotion science.
The maps are based on what people report feeling, not on scans of energy in the body. That distinction matters, and it is easy to lose when the images circulate online. Here is what the researchers did, what they found, and how to read the results.
The study behind the body maps
The paper, titled "Bodily maps of emotions," was written by Lauri Nummenmaa, Enrico Glerean, Riitta Hari and Jari Hietanen and appeared in the Proceedings of the National Academy of Sciences (PNAS). It was published online at the end of December 2013 and announced by Aalto University in early February 2014.
The team ran a series of online experiments with 701 volunteers from Finland, Sweden and Taiwan. Participants were given a prompt designed to evoke a feeling: an emotional word, a short story, a film clip, or a photograph of a facial expression. Next to it they saw two blank body silhouettes. On the first they coloured the regions where they felt activity becoming stronger or faster; on the second, the regions where it became weaker or slower.
The researchers then combined thousands of these drawings and used statistics to see whether each emotion produced its own recognisable pattern.

The figure shows the combined maps for fourteen states: anger, fear, disgust, happiness, sadness, surprise and a neutral state on the top row, and anxiety, love, depression, contempt, pride, shame and envy below. Warm colours mark areas where people reported increased sensation; blue marks reduced sensation.
What the maps show, emotion by emotion
A few patterns stand out when you look at the figure closely:
- Happiness was the only emotion that people coloured across nearly the entire body, with the strongest sensations in the head and chest.
- Love looks similar but stops above the knees, with heat in the face, chest and lower belly, the region people associate with "butterflies."
- Anger concentrates in the head, chest and arms, with particular intensity in the hands, which fits the urge to act or strike.
- Fear and anxiety centre on the chest, matching the familiar sensations of a racing heart and tight breathing.
- Disgust is felt mainly around the mouth, throat and stomach, the parts of the body that would reject something harmful.
- Sadness and depression show cool, blue limbs. People describe a loss of energy in the arms and legs, while depression in particular reduces sensation almost everywhere.
- Shame shows warmth in the face and chest, echoing the experience of blushing.
- Neutral is almost entirely dark, as expected.
Statistical classifiers could tell the maps apart with good accuracy, which means each emotion's pattern was distinct rather than a vague general arousal.
Why emotions feel physical
Emotions are not purely mental events. When you are frightened, the autonomic nervous system speeds the heart, shifts blood toward the large muscles and changes breathing. In embarrassment, blood vessels in the face widen and the cheeks redden. Disgust can trigger nausea. The brain constantly monitors these internal signals, a sense that scientists call interoception.
A long line of theorists, from William James in the 19th century to modern researchers such as Antonio Damasio, has argued that perceiving these bodily changes is part of what an emotion is. The Aalto team proposed something in that spirit: that the body-based patterns people report may help produce consciously felt emotions, rather than just accompanying them.
Similar across cultures
One of the more interesting results was how consistent the maps were between the Western European participants (Finnish and Swedish) and the East Asian participants (Taiwanese). The patterns lined up closely, which led the authors to suggest that these bodily sensation maps may be culturally universal and rooted in biology.
That conclusion should be held with some care. Three countries are not the whole world, and all participants were reached online. Language also plays a role: many expressions, such as "boiling with anger" or "a heavy heart," tie emotions to the body, and people may partly draw on these shared metaphors when they colour a silhouette. Later work by the same group, mapping a wider range of feelings in larger samples, has found similar patterns, but cultural influence has not been ruled out.
Common misunderstandings
"The maps show energy or vibrations in the body." They do not. Each map is an average of what participants said they felt. No thermometers, scanners or energy measurements were involved. The colours represent reported sensation, not heat or frequency.
"The study proves emotions cause disease." The research did not look at health outcomes at all. Long-term stress and emotional wellbeing do affect health in many documented ways, but that is a separate body of evidence.
"Everyone feels emotions in exactly these places." The maps are group averages. Individuals vary, and some people, including those with alexithymia (difficulty identifying their own feelings), may notice bodily signals less clearly.
How to use this in everyday life
The maps offer a simple, practical idea: your body often notices a feeling before your thoughts do. A tight chest before a meeting, clenched hands during an argument or a heavy, slowed-down feeling across a long week can all be early signals worth paying attention to.
Many people find it helpful to pause and run a quick check. Where do I feel this right now? Is it warm, tight, heavy, restless? Naming the sensation and the emotion together can make it easier to respond instead of react. Mindfulness practices such as the body scan are built on exactly this skill.
The researchers themselves suggested the maps might one day serve as a tool for studying emotional disorders such as depression and anxiety. If persistent low mood, anxiety or physical symptoms are affecting your life, talk to a doctor; noticing the body is a useful habit, not a diagnosis.
