Multi-dimensional constitution test · K-Health

One of the four is you.

Same dinner, same air-conditioning — one of you reaches for a blanket, one opens the window. Four bodies, four climates.

chejil (체질) — your constitution: the way your body tends to warm up, digest, rest and react.

Why am I always cold?
(or always hot?)

Four people at one table under an air-conditioner: one wrapped in a scarf, one fanning, one going for a second bowl, one already standing up

Same table, same food, same air-conditioning — and four bodies react four ways. Korean medicine has had a story about this for a long time, and this test, written by a Korean medicine doctor, tells you where you sit in it.

Not willpower, not mood — your body's default setting.

Where this comes from

A framework Korea has used for over a century, rewritten in everyday words.

1894

Donguisusebowon

A Korean medicine doctor keeps noticing that the same food and the same weather land differently on different people. He sorts people by how their bodies run — warming, digesting, resting, reacting — and names four constitutions in a book, the Donguisusebowon.

Now

Four figures side by side: one with a flame on an open hand, one reaching forward in the wind, one in a scarf sitting on a rock by the water, one with a sprout and roots

That idea is still the everyday language of Korean medicine — and of ordinary conversation in Korea. "What's your constitution?" is a normal question.

ilmi

Four constitutions + three more readings

We kept the frame and added what the clinic reads alongside it — patterns, phases, balances — rewritten in plain words you can use on a Tuesday.

Four constitutions aren't the whole story

Constitution is climate, balance is weather

Even a desert gets rainy days. Your constitution is like the climate — not frozen, but slow to change, so the big pattern holds for a long time. Your balance is today's weather: running warm or cool, low on reserves or overloaded — and it can shift with the season, your sleep, and your stress, sometimes within weeks. The report reads both, and a retest in a month puts the two forecasts side by side.

So a Spark, who runs warm by constitution, can still read cool today. Weather changing isn't a fault — it's normal; constitution doesn't move that fast. A quiz that only reads climate misses this.

CLIMATEConstitution

The slow side. The big pattern holds for a long time.

WEATHERBalance

Moves in weeks — with the season, sleep, stress and what you've been eating.

One page, before you start

This isn't a clinic test. It's a getting-to-know-your-body test.

In Korea, the constitution questionnaire used in clinics is part of real care — longer, more sensitive, answered across the table from a practitioner.

No diagnosisNo prescriptionUnderstanding + small daily adjustments

To — whoever opens this report

ilomi starts from the same frame but with a different purpose: not to diagnose anything, but to see which way your body leans — and to answer questions like "why am I always cold?" in your body's own words.

	Clinic questionnaire	ilomi
Used for	Clinical judgement	Getting to know your body
Questions	Deeper, more sensitive	Everyday words, light
How you answer	With a practitioner	On your own, about 10 min
What comes out	Diagnosis and treatment plan	Understanding + small daily adjustments

So the report has no diagnosis and no prescription.

— ilomi · made by a licensed Korean medicine doctor

For self-understanding

Okay, but…

Is this medical?

No — it's for self-reflection and wellness. It doesn't diagnose or treat anything.

Isn't this just one of those four-type quizzes?

The four constitutions are the face of it — the part people share. Underneath, the same answers are also read as 3 patterns, 5 phases and 8 balances, each on its own. That's the multi-dimensional part.

What's chejil?

Chejil (체질) is the Korean word for constitution — the way your body tends to warm up, digest, rest and react. It's the lead character of this test; the other three readings are the weather around it.

Constitution is climate, balance is weather — meaning?

Your constitution can change, but slowly, the way a climate does. Your balance moves with the season, sleep and stress, sometimes within weeks. The report reads the two separately so one doesn't get mistaken for the other.

Is the Five Phases map a score for my organs?

No. It isn't an organ scan. It's the tradition's way of grouping everyday experiences — stress, digestion, sleep, recovery — into five jobs and showing where the load sits this month.

Which constitution is best?

None. The story needs all four characters.

Is the one-minute read accurate?

It's a lean, not a verdict — fifteen questions can only read constitution. The full test adds the other three readings and confirms it.

Can I retake it?

Yes. Your constitution should hold; your balance won't. A month later is the fun part — the report overlays the two.

So — which of the four are you?
