Felti draws on real research about how emotions register in the body. But the way we turn that into five body archetypes is our own lens for self-reflection - not a clinical test. This page lays out exactly where that line is, because you deserve to know.

These findings are peer-reviewed and broadly accepted. They’re the ground Felti is built on.
Across five experiments, 701 people from Finland, Sweden and Taiwan colored in where they felt bodily sensations change for each emotion. The resulting maps were strikingly consistent across these cultures - anger and happiness lit up the arms and upper body, while sadness drained sensation from the limbs. These are maps of felt, self-reported sensation, not measurements of activity inside specific organs.
A large body of research shows the brain builds emotional feeling partly from internal bodily signals - heartbeat, breathing, gut. This ‘sensing from the inside,’ called interoception, is closely tied to how we experience and regulate emotion. This is the strongest, least-disputed link between feeling and the body.
Psychological stress is associated with measurable increases in muscle tension - including in the neck and shoulder (trapezius) region, recorded by EMG. This is concrete evidence for the everyday intuition that stress ‘sits in your shoulders’ - though it links stress to tension in general, not any one body part to any one emotion.
Reviews of slow, paced breathing find it reliably increases vagally mediated heart-rate variability and parasympathetic activity, helping the body downshift out of stress arousal. This effect is well supported on its own - independent of any single theory about why it works.
Felti takes that real foundation and builds a self-reflection tool on top of it. The five body archetypes - and the idea that a given zone reflects a specific emotional pattern - are our interpretation, not a scientific classification.
No peer-reviewed work establishes a one-to-one map of ‘jaw = held anger’ or ‘shoulders = over-responsibility.’ Those connections are a heuristic for noticing, not a measurement.
Research shows people feel emotions in broadly consistent body regions - but those regions are coarse and overlap heavily. The specific, named meanings Felti attaches are our own framing.
Your Felti result is a reflective lens and a conversation starter - not a diagnostic instrument with established reliability or validity.
We’d rather show you the strongest objection than hide it. Psychologist Lisa Feldman Barrett’s research argues that emotions are constructed in the moment and do not have consistent bodily ‘fingerprints’ at all. If she’s right, no tool can read a fixed emotion from a fixed body zone. We find the body-emotion link genuinely useful for reflection - but the honest answer is that this science is real and still unsettled, and Felti’s zone-to-emotion map is a lens, not a law.
Lisa Feldman Barrett · The theory of constructed emotion, 2017Two famous names come up constantly in body-emotion conversations. We draw inspiration from them - but we don’t lean on them as proof, because the science isn’t settled.
An influential framework linking the vagus nerve to emotional states and safety. A large group of researchers has argued its core claims aren’t well supported by autonomic physiology. We don’t cite it as evidence - but the simple, well-established finding that slow breathing calms the nervous system stands on its own.
A hugely influential book that brought the mind-body connection to a wide audience and popularized body-based approaches. It is one clinician’s perspective, not peer-reviewed primary research, and the literal idea that emotions are ‘stored’ in the body is debated. We treat it as inspiration, not settled science.
Think of your Felti archetype as a mirror, not a measurement - a starting point for noticing how stress shows up in your body, and a prompt for reflection. It can’t tell you what’s medically going on. If something resonates, use it to get curious. If it doesn’t, set it down.

The science Felti draws on - that emotions involve the body, and that we sense our internal states (interoception) - is well established. Felti’s specific five-archetype system is our own interpretive lens for self-reflection, and has not been clinically validated as a diagnostic test.
People report feeling emotions in broadly consistent body regions, but emotions don’t map onto the body in a fixed, one-to-one way - and some researchers argue they have no consistent bodily ‘fingerprint’ at all. Felti’s zone-to-emotion connections are a reflective lens, not a measurement.
