Part 4 of 8 in the "how TCM assesses poor sleep" series. The other seven are listed at the foot.
"I just don't sleep well" becomes five or six questions in a consultation. This part covers the first two areas — the shape of the sleep itself, and the daytime — and why they are asked in that much detail.
The short version
- A consultation takes "poor sleep" apart: what time you go to bed, how long until you fall asleep, how often you wake, what time you wake, whether you can get back to sleep.
- The daytime gets asked about too: energy, drowsiness, whether concentration has changed. The WHO standard's description of 不寐 covers both the night and the day, so the daytime is half the definition.
- The first two items on Singapore HealthHub's sleep-record list are the same: the time you went to bed and woke up, total sleep hours and perceived quality of sleep — the two lists line up almost one to one.
- The same HealthHub page says that if a sleep problem has persisted for at least a month, caused significant distress and interfered with social or work life, one could consider keeping a sleep record.
First, the things that cannot wait
You snore with pauses in breathing, or wake up gasping; daytime sleepiness is severe enough to affect driving or work safety — see a doctor for investigation first.
Mood is persistently low, anxiety is hard to control, or you have thoughts of harming yourself — this is not something to wait on. Call 999 now, or go to the nearest hospital emergency department. To talk to someone, the Ministry of Health's Talian HEAL 15555 is open every day from 8 am to 12 midnight, public holidays included; Befrienders KL is open 24 hours on 03-7627 2929. You can also contact your doctor.
The full list, and the reason for each, are in part 8. TCM and Western medicine complement each other; it is not a choice between them.
A note: this section is general information only. For conditions like these, follow your doctor's diagnosis and treatment, and seek medical attention when you need it.
I. What the practitioner asks, and why

Across a consultation, a practitioner will generally want to understand five areas. After each item is why it matters in TCM theory — with a list from the Western side placed alongside, to see whether the two are asking about the same things.
(What "inquiry" is, is part 1: the WHO's standard terminology for TCM defines it as collecting information on the disease occurrence, progression, previous diagnosis and treatment and present symptoms by talking to the patient or the person who accompanies them.)
Singapore's HealthHub (Ministry of Health), on its Sleeping Well page, puts it this way: if a sleep problem has persisted for at least a month, caused significant distress and interfered with social or work life, one could consider keeping a sleep record; the record could allow one to calculate total sleep time, identify sleep disruptions and other unknown factors that may influence sleep, and it would also serve as useful information for healthcare professionals in deciding whether there is a sleep disorder.
The items it lists for the record line up almost one to one with the areas a TCM consultation asks about. Of our five areas, the first two are in this part, the bodily signals are part 3, and mood and current medication are part 5.
① The shape of the sleep itself — what time you go to bed, how long until you fall asleep, how often you wake, what time you wake, whether you can get back to sleep.
Why it is asked: the Chinese University of Hong Kong's Integrative Medical Centre article files difficulty falling asleep, light sleep with easy waking, much dreaming, early waking and waking still tired all under a disturbance of yang entering yin — one process, which can go wrong in several places, so the shape has to be pinned down. (That process, and the several places, are part 2.)
The first two items on HealthHub's record list are the same: the time you went to bed and woke up, total sleep hours and perceived quality of sleep.
Its third item goes a step further: a record of the time spent awake and what you did in it — its own examples are "got up, had a glass of milk" and "stayed in bed with eyes closed". Those two examples are a concrete answer to why the "woke" column is worth keeping: two wakings spent walking around and two spent lying still are not the same thing in a consultation.
Worth noting: those four or five shapes are descriptions of the sleep, not categories of people. Which shape goes with which situation is a matter for after the inquiry.
② How the daytime goes — energy, drowsiness, whether concentration has changed.
Why it is asked: the WHO standard's description of 不寐 covers both the night and the day — an inability to obtain normal sleep, and drowsiness and low energy during the day. The daytime is half the definition, not a side question. Hours slept and how restored you feel do not always match.
If daytime sleepiness is already affecting driving or work safety, that is a different matter: see a doctor for investigation first — the reason is in part 8.
II. Why the two lists look so alike
TCM theory asks where the process of yang entering yin is being interrupted; HealthHub records total sleep time, sleep disruptions and unknown factors. The two languages do not translate into each other, but both look at the whole day around the sleep, not only the hours of the night.
That is also why keeping a 7-day sleep log before the consultation saves work: the questions above already have their answers on the log. The four columns, and how a log is read, are part 7.
💡 Remember: these questions are not there to put a label on you. The practitioner is assembling a whole picture, not matching you against a list.
The words in this part
Two of the four come from the World Health Organization's 2022 standard terminology for TCM; two are the HealthHub page's own terms.
- Inquiry (问诊) — the WHO standard: collecting information on the disease occurrence, progression, previous diagnosis and treatment and present symptoms by talking to the patient or the person who accompanies them. The full account is part 1.
- 不寐 (bú mèi) — the same standard's description: an inability to obtain normal sleep, with drowsiness and low energy during the day. The night and the day are both written in, which is why the daytime gets asked about.
- Sleep record (睡眠记录; also sleep diary) — HealthHub's term. It says a record could allow one to calculate total sleep time and identify sleep disruptions and other unknown factors.
- Perceived quality of sleep (自觉的睡眠质量) — one of the items on HealthHub's record list, sitting next to total sleep hours. It is your own assessment, not an instrument reading.
Frequently asked
I can't say how long it takes me to fall asleep — is an estimate all right? Yes. The log in part 7 says in terms that an estimate is fine. The point is not minute-accuracy; it is which nights were different.
How long does a sleep problem have to go on before a log is worth keeping? HealthHub puts it this way: if the issue has persisted for at least a month, caused significant distress and interfered with social or work life, one could consider keeping a sleep record. That is that page's threshold; it also says a record would serve as useful information for healthcare professionals in deciding whether there is a sleep disorder.
Do not: treat "I sleep badly every night" as the whole account — what the inquiry needs is which nights, and in what way.

👉 If you are not sure where to begin with your own poor sleep, you are welcome to book an online consultation with HansMed, where a practitioner registered under the T&CM Act 2016 can assess it with you; if anything in "First, the things that cannot wait" above or in part 8 applies, see a doctor first.
Sit with a licensed TCM practitioner from wherever you are.
