Part 4 of 6 in the "Stress, sleep and TCM theory" series. The list of the other five is at the foot of this part.
Definitions and model done, this part covers the habits TCM theory attaches to them, and the sleep-hygiene advice of public-health bodies.
These are daily arrangements for people in general, not a prescription for any pattern.
The short version
- Hong Kong's Chinese Medicine Regulatory Office names regulating the emotions, a balanced diet, careful daily routine and moderate exercise as the four cornerstones of TCM health preservation.
- Its sleep guide says TCM holds that one should "put the heart to sleep before the body" — the mind must be calm before bed.
- The table below sets those positions beside Singapore HealthHub's sleep-hygiene advice: six situations, six habits.
- HealthHub's two figures are four to six hours before bedtime for caffeine, alcohol and big meals, and at least 60 minutes off the phone, computer or tablet.

First, the things that cannot wait
⚠️ A safety note: TCM and Western medicine complement each other; it is not a choice between them. Difficulties with mood and sleep have a layer that needs professional assessment, and a TCM consultation does not substitute for that assessment. Asking for help is not weakness — there is professional support for this.
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.
All seven items, and why each one means seeing a doctor first, are in part 5.

I. Both positions, side by side in one table
Hong Kong's Chinese Medicine Regulatory Office names regulating the emotions, a balanced diet, careful daily routine and moderate exercise as the four cornerstones of TCM health preservation.
Its sleep guide adds: TCM holds that one should "put the heart to sleep before the body" — the mind must be calm before bed; worry harms the heart spirit, and anger stirs liver fire and unsettles the shen, affecting sleep. (The heart shen, 心神, is the theory's term for whether mental activity settles; part 1 defines it. Liver fire is a separate family of patterns, not covered here.)
In the table below, the first two columns are the TCM-theory position, the third is Singapore HealthHub's sleep-hygiene advice, and the fourth points back to part 5.
| Situation | What TCM theory says | Usual practice | When to see a doctor first |
|---|---|---|---|
| Crunch season, tense all day | WHO standard: the liver likes to flow freely and dislikes suppression, qi should move; 「怒伤肝」 — excessive anger impairs the liver's function of maintaining the free flow of qi. Hong Kong Department of Health: moderate exercise is a cornerstone | HealthHub: a daily block of exercise, earlier in the day; avoid vigorous exercise in the late afternoon and evening | Anxiety that is hard to control and affects daily life or work (part 5) |
| Lying down, mind won't stop | Hong Kong Department of Health's sleep guide: "put the heart to sleep before the body"; worry before bed harms the heart spirit | Hong Kong Department of Health: wind down before bed — reading, a walk or a warm bath; HealthHub: deep breathing and muscle relaxation | Long-standing insomnia, or needing medication to fall asleep (part 5) |
| Weekend catch-up sleep, routine gone | Hong Kong Department of Health: a regular routine — sleep at fixed times, avoid late nights and lying in; its sleep guide: go to bed and get up on time | HealthHub: go to bed and get up at the same time every day, weekends and holidays included | Persistently low mood, or loss of interest in things you used to enjoy (part 5) |
| The third kopi of the afternoon | Hong Kong Department of Health's sleep guide: drink less strong tea, coffee and other stimulating drinks, so as not to be too stimulated to sleep | HealthHub: avoid caffeine, alcohol and big meals four to six hours before bedtime | Marked weight change, palpitations or tremor alongside it (part 5) |
| Dinner pushed to half past nine, replying to messages while eating | WHO standard: stomach qi should flow downward unobstructed; the standard's description of the liver–stomach disharmony pattern is that it often occurs when liver qi stagnation affects the descending of stomach qi (part 2) | HealthHub: avoid big meals four to six hours before bedtime | Anything listed in part 5: see a doctor first |
| Scrolling until you fall asleep | Hong Kong Department of Health's sleep guide: keep troubling things from disturbing the mind before bed | HealthHub: no mobile phone, computer or tablet for at least 60 minutes before bedtime | Thoughts of harming yourself: call 999 now, or go to the nearest hospital emergency department (part 5) |
Remember: in TCM theory, the direction for the liver is move and loosen; the direction for the shen is settle and keep fixed times. Daytime exercise, winding down before bed, a fixed sleep window, and the timing of caffeine, dinner and screens — six habits, and all of them can start tonight.

II. Three additions
- Keep any nap short. TCM health preservation favours the "midday and midnight sleep" — the Hong Kong Department of Health's sleep guide puts it this way: be asleep at the midnight hour (子时), and a short nap at the midday hour (午时) is also fine; a nap of about 15 minutes to 1 hour is considered suitable. HealthHub's advice differs: avoid daytime naps; if you must, keep it within 30 to 45 minutes, and not in the evening. The two really do differ, and this part sets them out as they stand.
- The bedroom: the Hong Kong Department of Health's sleep guide says soft light, good ventilation, cool in summer. HealthHub says a room that is too hot or too cold can keep you awake.
- Not asleep after 20 minutes: HealthHub's advice is to get up and do something quiet; no television or internet.
These three sit outside the table and do not count among the six habits. This part does not split the difference for the two bodies — which one suits you is for you and the practitioner to discuss at the consultation.
Fitting it into life in Malaysia
- The evening kopi or teh tarik at the mamak: it counts as caffeine. HealthHub's advice is to avoid it four to six hours before bedtime. If you sleep at eleven, any cup after five falls inside the six-hour window.
- The air-conditioned room: on HealthHub's account, too cold also keeps you awake. Set it to comfortable, not to the lowest.
The words used in this part
- The four cornerstones — the Hong Kong Chinese Medicine Regulatory Office's term: regulating the emotions, a balanced diet, careful daily routine and moderate exercise.
- The midday and midnight sleep (子午觉) — the TCM saying quoted in the Department of Health's sleep guide: be asleep at the midnight hour, and a short nap at the midday hour is also fine.
- Sleep hygiene — the term public-health bodies use for this class of daily advice; everything in the table's third column belongs to it.
Frequently asked
How many hours before bed should I stop drinking coffee? On Singapore HealthHub's advice, avoid caffeine, alcohol and big meals four to six hours before bedtime. That HealthHub page does not state the reason behind the figure, and this part does not supply one for it.
Are naps fine or not? The two bodies do not give the same answer, and section II sets out both as they stand: the Hong Kong Department of Health's sleep guide says a short nap at the midday hour is also fine, about 15 minutes to 1 hour; HealthHub's advice is to avoid daytime naps, and only if you must, within 30 to 45 minutes. Which suits you is for the consultation.
Will these habits fix my "liver qi stagnation"? This article does not say "what the effect will be", because that belongs to an individual assessment, not to an article. The practices in the table are public-health advice for people in general, not a prescription for any pattern; 「肝气郁结」 is a practitioner's term after assessment — see part 1.
Better not to: treat this table as a course of treatment in place of a consultation. When anything in part 5 appears, see a doctor first.
The other five parts in this series
- Part 1: What 「肝气」 and 「心神」 mean — two definitions, and what they are not
- Part 2: What "liver qi" models — one concept, three threads
- Part 3: The two languages side by side, and one crunch-season week
- Part 5: See a doctor first in these situations — seven signs, and the reason for each
- Part 6: What actually happens at the consultation — routine first, then the pattern, then the direction
👉 If you are not sure where to begin with your own stress and 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 part 5 applies, see a doctor first.
Sit with a licensed TCM practitioner from wherever you are.
