Reading Your Own Body

How to notice what a body is doing — your own, and those of the people in your house — precisely enough to act on, and clearly enough to know when to ask someone else.

~13 min read

The skill nobody teaches you

You have spent your whole life inside one body and nobody has taught you to look at it. Noticing what it is doing — precisely, in words, over time — is on nobody’s curriculum, and most adults arrive at forty with three settings for it: fine, tired, and something’s not right.

It is a missing skill, not a character flaw, and accurate noticing depends on words. The nine system lessons behind you were vocabulary as much as anatomy: before them a bad fortnight was a bad fortnight; after them you can say digestion has been slower since the holiday, that recovery takes two days where it took one, and that it started when the schedule changed.

A Healer in Every Home said the most valuable thing a healer has is a year of ordinary attention. This is how it gets collected.

Observe, interpret, conclude

Everything you can know about a body arrives through three different acts: you observe, you interpret, you conclude. Almost every mistake anyone makes about their own health happens at the second, and nobody notices taking it.

What you observe

Raw and dated: "woke at three, six nights in ten". No cause, no meaning.

What you interpret

"My sleep is off because of stress." Possibly true — but a story wrapped around an observation, and in the same handwriting as the facts.

What you conclude

"I am moving screens out of the bedroom for a fortnight and seeing." Decisions are fine; what matters is knowing which of the three you are doing.

Diagram to come

Three stacked bands read bottom-up, each wider than the one beneath so the space for error visibly widens. Bottom, narrow, green: one dated line of plain fact. Middle, wider, terracotta: the same fact with a cause attached, drawn with three alternative causes branching off it so the fork is on the page rather than implied. Top, widest, slate: a decision. One vertical arrow runs up through all three. The branches in the middle band are the point of the drawing and must be drawn.

What is observable without a laboratory is more than people expect.

  • Sensation — where, what kind, how strong, whether it moves.
  • Energy — a shape across the day, not a score.
  • Sleep — time down, times awake, how you woke. Three facts collapsed into "slept badly".
  • Appetite, digestion in the two hours after eating, skin, mood.
  • Recovery — how long after effort or a late night until you are normal. The most informative, least tracked measure there is.

Observation is not diagnosis

A healer notices patterns. Naming a condition is a different job, done by someone trained and licensed, with tests you do not have. Nothing observed at home adds up to a diagnosis — not a long record, not a striking pattern, not a search result. This is different from professional medical care and does not replace it. Observations are for deciding what everyday support a body gets, and for walking into an appointment with better than "I have not been right for a while".

Go deeper: why the signal is blurry before you ever interpret it

Interpretation goes wrong so readily partly because the raw material is poor. Vision is high resolution — over a hundred million receptors in each eye. Interoception, the sense reporting your internal state, has nothing like that budget. Its fibres sit in the gut wall, in blood vessel walls, in the airways and around the heart, run up the vagus nerve and reach a fold of cortex called the insula. There are far fewer than in skin, and some tissue has none.

Then the wiring. Fibres from an internal organ enter the spinal cord at the same segments as the skin fibres from a patch of body wall, and the brain — used to well-localised traffic from skin and vague traffic from everything else — attributes the signal to skin. Irritation of the diaphragm is commonly felt at the tip of the shoulder for exactly this reason: its nerve supply enters at the third, fourth and fifth cervical segments, and so does sensation from the skin there.

The consequence is worth more than the anatomy: location is the least reliable thing you observe and timing is the most. Record when something happens and what else was true at the time, more carefully than where it seems to come from.

A single observation is almost worthless

You slept badly on Tuesday. That carries almost nothing on its own; it means something only against a baseline — what this body is like when nothing is going on. Attention turns inward once something is wrong, so every reading most people hold was taken on a bad day. That is how a drift runs unnoticed for a year.

The honest minimum is one line a day: a scrappy line kept for a fortnight beats a spreadsheet kept for four days and abandoned. Five fields, sixty seconds.

  1. 1.Sleep. When you went down, times awake, how you woke.
  2. 2.Energy. One word for the morning, one for the afternoon.
  3. 3.Digestion. Comfortable or not; regular or not.
  4. 4.The one thing specific to you.
  5. 5.What was unusual about the day. One clause — this field does all the work later, and everybody skips it.

Photograph to come

A real record rather than a designed one: a cheap notebook open on a kitchen table showing five or six scrappy handwritten lines a day, some days plainly skipped — or the same thing in a phone notes app. Imperfect handwriting, one visible crossing-out. It must look achievable in sixty seconds; the point is that this is not a tracker, a chart, or a screenshot of a wellness dashboard. Sits in the existing lifestyle photography register.

Start it tonight, while nothing is wrong: a record begun because something is already off has a bad day at the top and no ordinary days under it. Protocols holds the other half.

Go deeper: why memory cannot be used as a baseline

The obvious objection to keeping a record is that you could simply remember. You cannot, and not because your memory is bad. Recall of a bodily state is reconstructed at the moment of asking, and the strongest input to it is how you feel now. Ask someone in a good week how the last month has been and it was fine. Ask them in a bad week and the same month was awful. Both answers are honest; neither is a report of the month.

A second effect stacks on once you have changed something: from the moment you start anything you have a stake in it, and recall turns selective without anyone deciding to be dishonest. Which is what makes a written baseline worth more than it looks. Not precision — the lines are scrappy — but that the line written on the fourth cannot be edited by what you believe on the twenty-fifth.

The system check: nine questions

Once a fortnight, or any time something is off and you cannot say what, go round the nine systems in order and ask one question of each. Five minutes. Most rounds find nothing, which is a result worth having, and going in order stops you looking only where you suspect.

1. Digestive

"What happens in the two hours after you eat?" Comfort, heaviness, or nothing at all — and nothing at all is the healthy answer, easiest to forget to record. The digestive system.

2. Metabolic

"What shape does your energy make across the day?" Where it starts, where it drops, whether the drop lands at the same hour. The shape is the observation; one day’s level is noise. The metabolic system.

3. Respiratory

"Can you take one full, slow breath through your nose?" Try it before answering — most people answer from memory and are wrong. Then: can you still talk at the top of the stairs. The respiratory system.

4. Nervous

"How long does it take you to come down?" Not how strongly you react — recovery is more informative and changes first. Minutes, an hour, the rest of the evening. The nervous system.

5. Immune

"How has the household been this past year, and how long does anyone take to get back to normal?" Frequency and recovery, counted over months, never one week. The immune system.

6. Endocrine

"Does it repeat on a schedule?" Weekly, monthly, seasonally. Anything on a cycle says something different from anything random — and a cycle is invisible from inside a week. The endocrine system.

7. Cardiovascular

"What are your hands and feet like, and how fast does your breathing settle after stairs?" Warmth at the extremities and recovery after mild effort. The cardiovascular system.

8. Musculoskeletal

"Where do you hold tension, and how long until you are normal after effort?" Nearly everyone names the place instantly — the information was there, never asked for. The musculoskeletal system.

9. Integumentary

"What has your skin done this month?" The only system you inspect by looking, and often where a change in the household’s week shows first. The skin.

Diagram to come

A ring of nine numbered stops read clockwise from the top, one per body system, each carrying its system name. The ring visibly closes back onto stop one, because this is a round that repeats rather than a checklist that finishes. Use the same colour per system as the body-system lesson pages. Each stop is tappable and goes to that system’s lesson.

Ask all nine even when you are sure it is the third: an ordered list earns its keep in the questions you would not have thought to ask. Answer out loud or in writing — words force a choice between slower and heavier. Where a question lands somewhere unfamiliar, the organ library is the level underneath.

Signal and noise

A body is noisy. It varies day to day for reasons unconnected to anything you did, and the difficulty of observing one is separating variation that means something from variation that is just what bodies do.

Start with the discipline that prevents most errors. Two readings that differ are not a change; they are a body. A change is a level that has moved and stayed moved for a fortnight, or a pattern that has appeared and repeated; anything less is an anecdote about a Tuesday. When several columns go off together, look here first.

  • Sleep. Two short nights degrade energy, appetite, mood, digestion, recovery and skin at once — the pattern mistaken for something systemic.
  • Ongoing stress — not a mood but a state reaching nearly every system.
  • Water. Dull, and responsible for much that gets blamed on something more interesting.
  • The time of the month, for anyone who has one — a normal cycle moving sleep, appetite, mood and energy on a schedule.
  • A change of season — light, temperature, food and movement at once, invisible because it is annual.
  • Anything that changed in the house — a new schedule, a new job, a move.

Then the effect that fools nearly everybody, including those who know about it. You do not start something on an average day; you start on a bad one, because that is what makes anyone start anything. A bad day sits at the far end of your ordinary variation, so the days after it are likely to be closer to your middle whether you did anything or not. Statisticians call it regression to the mean. In a household: everything begun during your worst week appears to work.

Diagram to come

One wobbling line across about six weeks, varying around a flat horizontal average, with a shaded band showing the ordinary range so every wobble is visibly inside it. One deep trough is marked by a vertical rule labelled as the day you started something, and the line climbs back towards the average after it — as it also visibly does after two other troughs where nothing was started, which is the entire argument and must be on the page. Deliberately no second line and no comparison group: the point is that there is nothing to compare against.

So judge anything by where the level sits a month later, not by the relief on day three. The second bias arrives with a receipt: having just bought something, you notice the evidence that fits. Decide beforehand what you expect to change, then count the days it did nothing as carefully as the days it worked.

Which leaves the rule that makes any of this learnable: change one thing at a time. Move dinner earlier, start something at night and buy a new pillow in the same week, and if sleep improves you have learned that something worked — not what. Give each change a fortnight.

Go deeper: why your own evidence is weak evidence, and worth collecting anyway

A properly conducted trial has things you cannot get at a kitchen table: a control group living the same weeks without the change, random allocation, blinding, enough people for chance to average out, and someone other than the participant measuring. You are one person, unblinded, measuring yourself, in a life changing for a dozen other reasons. So personal experience cannot establish whether something works in general, whether it caused what followed rather than merely preceding it, or whether an effect was real rather than you, expecting, across days that were going to be better anyway. What it can establish is shorter, and not small.

  • Whether it suits you — whether you tolerate it, like it, and will keep it up in an ordinary week.
  • Whether any effect is large enough to matter. One you cannot detect across a month is too small to organise an evening around.
  • What your own patterns are. That your worst weeks arrive three days after your shortest nights is a fact no trial will produce.

So hold conclusions loosely and keep two sentences apart. "It works" is a claim about the world, and you are not equipped to make it. "It has been better since I started, and here is what I wrote down" is a claim about you — the only one worth making to anybody else.

Reading the people you live with

Most of what a healer in the home does is observing somebody else — at one remove, through a person with their own threshold and their own reasons for the answer. So stop relying on asking. The most reliable information is behavioural: what they ate, when they went to bed, whether they came to the table, whether the thing that always makes them laugh did. None of it needs describing, and it changes first.

  • Ask about a specific window. "How did you sleep last night" gets an answer; "how have you been sleeping" gets "fine".
  • Ask what has changed rather than what is wrong — the first is a question, the second an accusation.
  • Never put your answer inside the question: "is your stomach bothering you again?" gets agreement from a tired person, and teaches nothing.
  • Ask once, then leave it. Write down their own words.

Who are you trying to read?

Three cases in almost every household, and they do not respond to the same approach.

One line does not move. You may observe, say what you observed, and offer. You may not decide for another adult, and you may not make a person into a project. A household with someone who watches carefully and speaks plainly once is looked after. One where somebody monitors everybody is not.

When to stop observing and get help

There is a point where observing is the wrong thing to be doing, and knowing where it sits is part of this skill, not a failure of it. It is not far away. Cross it early and often.

Everything here is for the ordinary: the slow drift, the unremarkable fortnight, the pattern quietly repeating since spring. The moment a situation stops being ordinary, the next step is not a better record. It is a professional, today. Go now rather than later for any of these.

  • Anything sudden — a change that arrived in minutes or hours, not weeks.
  • Anything severe. Intensity is information on its own.
  • Anything getting worse rather than settling.
  • Anything unresolved. A change still there after a fortnight is no longer a bad patch.
  • Anything frightening — to you, or to the person it is happening to. Fear is a signal about the situation.
  • Anything involving a child. Lower the threshold, lower it again for an infant.
  • Anything in someone pregnant, nursing, elderly, under medical care, or taking medication.
  • Any change nobody can account for, in weight, appetite, sleep or energy.
  • Anything a practitioner has asked you to watch for.
  • Anything where the honest answer to "what is going on here" is "I do not know". This covers what the nine above missed, and is the most important line here.

Getting help is part of the job, not the end of it

Proactive medical care sits at the top of the wellness chart in Natural Solutions — inside the model, not outside it. Everything here is different from professional medical care and does not replace it. A household that notices early and goes early is running the system as designed, and arrives with something most people cannot bring: weeks of specific, dated, unedited observations. Take the record with you. Never use observation as a reason to wait, and never use anything here as a reason to delay, stop or change care that you or anyone else is receiving or considering.

Bring five answers. When it started. What it has done since. What else changed at the time. What you have tried. What makes it better or worse.

Keep your interpretation separate from your observations and say which is which — the discipline of [observe, interpret, conclude](#what-observation-actually-is). "Here is what I noticed, and here is what I wondered" is a useful sentence. "I think it is this" hands over a conclusion in place of the data, and the data was the part only you had. And do not let the appointment end the observing.

Keeping a record you will actually keep

Capture takes sixty seconds. Reading it back is the half nobody plans for, and where the findings are.

  1. 1.Run it six weeks before drawing anything from it: a fortnight shows a week, six weeks a cycle.
  2. 2.Read it in one sitting, not day by day: a record read daily turns into a mood. Read the "what was unusual" entries first and on their own — every cause is in that column, and reading it apart stops you fitting each to its neighbour.
  3. 3.Look for three things: a level that has moved and stayed moved, something repeating on a schedule, two columns moving together with a lag.
  4. 4.Write one sentence of conclusion, date it, change one thing.

That date — the day you changed something — is the most useful number in the document: six weeks on, it is the only thing that says what was running when.

One last discipline. Change one thing, and write down what you expect beforehand. If the change is an oil, it goes on skin diluted in a carrier — dilution is not a way of using less, it slows evaporation and spreads the drop — and Safety is the authority on how much, and on which oils need more. Nothing you observe or change establishes that anything treats anything.

Keep oils away from eyes and inner ears, and out of reach of children. If you are pregnant, nursing, under medical care or taking medication, speak to your healthcare practitioner before use. Nothing here is intended to diagnose, treat, cure or prevent any disease.

Where next

That is Body Systems finished — nine systems, the organs underneath, and the skill that makes it usable. A vocabulary and a habit, and the habit compounds.

Start the record tonight, on an ordinary evening. It is the one instruction that only works if you follow it early.

Where this comes from

  • The Healer at Home Booklet — the chapters on daily attention and what a household can look after.
  • The doTERRA Live Guide — the wellness lifestyle model, where proactive medical care sits at the top of the chart, not outside it.
  • The nine body-system lessons in this course — the source of every question in the check.
  • Standard physiology references on interoception: visceral afferent pathways, the vagus nerve, the insula, and referred sensation.
  • Published methodological literature on regression to the mean, confirmation bias and the limits of single-subject observation.
