Part 4 of 6 in the "always tired" series; the other five are listed at the foot.
The order first: the situations listed in part 5 go to a doctor; once tests are clear, routine is one of the directions a TCM consultation talks about.
This part sets the two accounts side by side — the TCM-theory position from the Hong Kong Department of Health's public material, the public-health numbers each with their own source. Where the two differ, this article says so.
The short version
- The Hong Kong Department of Health's sleep guide: go to bed and get up at regular times, sufficient without being excessive.
- It also favours the "midday and midnight sleep" (子午觉): be asleep at the midnight hour, and a short nap at the midday hour is also fine.
- The American Academy of Sleep Medicine's numbers: set a bedtime early enough to get at least 7–8 hours of sleep; get up at the same time every day, even on weekends or during vacations.
- Singapore HealthHub's number: avoid caffeine four to six hours before bedtime.
- The two sources take different positions on naps — the Department of Health favours a short nap at the midday hour, while HealthHub advises avoiding daytime naps. Which suits you is something to raise at the consultation.
First, the things that cannot wait
Weight loss you did not intend, or breathlessness, palpitations or chest tightness alongside it — see a doctor for investigation first. The NHS states each separately: it is important to get it checked if you are losing weight without trying, and sometimes the cause can be cancer; and palpitations can be caused by a condition such as iron deficiency anaemia or an overactive thyroid (hyperthyroidism).
Persistently low mood, loss of interest, or thoughts of harming yourself — 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 [KKM-HEAL]; Befrienders KL is open 24 hours on 03-7627 2929 [BEF]. You can also contact your doctor.
The full list, and the reason for each, are in part 5. 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. The routine TCM theory attaches to it
Go to bed and get up at regular times; the actual amount of sleep varies by person, and should be sufficient without being excessive — that is how the Hong Kong Department of Health's sleep guide puts it.
It also favours the "midday and midnight sleep" (子午觉) — 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. (子时 is 11 pm to 1 am — that gloss is this article's.)
Before bed: drink less strong tea, coffee and other stimulating drinks, so as not to be too stimulated to sleep; keep the mind calm before bed — reading, a walk or a warm bath.
Notice how this section is written: when, how long, what not to do before bed — never what it will achieve. Neither does this article.
💡 Remember: what this section gives is an arrangement of hours, not a prescription for any pattern.
II. The public-health numbers
The American Academy of Sleep Medicine's (AASM) advice is: set a bedtime that is early enough for you to get at least 7–8 hours of sleep; get up at the same time every day, even on weekends or during vacations.
Singapore HealthHub's advice is: avoid caffeine, alcohol and big meals four to six hours before bedtime; avoid daytime naps — if you must, keep it within 30 to 45 minutes, and not in the evening.
The two sources take different positions on naps: the Department of Health's sleep guide favours a short nap at the midday hour, while HealthHub advises avoiding daytime naps. Which suits you is something to raise at the consultation.
The table below sets the TCM-theory position beside the public-health advice. The sourcing, stated once: "What TCM theory says" is all from the Department of Health's sleep guide, "Usual practice" is attributed cell by cell, and the last column is from the NHS's tiredness page and part 5.
| Situation | What TCM theory says | Usual practice | When to see a doctor first |
|---|---|---|---|
| A full night, and you wake as though you hadn't slept | Go to bed and get up at regular times; sufficient without being excessive | First check whether it really was enough: at least 7–8 hours (AASM); fixed sleep and wake times, weekends included (HealthHub) | Tired for a few weeks and not sure why (NHS) |
| Two or three in the afternoon and you can't keep going | 子午觉: a short nap at the midday hour is fine, 15 minutes to 1 hour | HealthHub: avoid daytime naps; if you must, within 30 to 45 minutes, not in the evening (the two differ — see above) | Tiredness that affects your daily life (NHS), or driving and work safety (part 5) |
| Weekend catch-up sleep, worse on Monday | A regular routine: bed and rising at set times | Get up at the same time every day, weekends and vacations included (AASM) | Tired with weight loss or mood changes alongside it (NHS) |
| The third kopi of the afternoon | Drink less strong tea, coffee and other stimulating drinks | Avoid caffeine four to six hours before bedtime (HealthHub); avoid caffeine in the afternoon or evening (AASM); separately, the WHO anaemia fact sheet notes that tea and coffee slow down iron absorption when consumed with iron-rich foods | Palpitations or breathlessness alongside it (part 5) |
| Crunch season, in bed after midnight | Be asleep at the midnight hour | A bedtime early enough for 7–8 hours (AASM); wind down before bed: reading, a walk, a warm bath (the Department of Health's sleep guide) | Persistently low mood (part 5); thoughts of harming yourself: call 999 now, or go to the nearest hospital emergency department (part 5) |
III. Fitting it into life in Malaysia
- Several kopi a day. No need to cut down first. HealthHub's advice is to avoid caffeine four to six hours before bedtime — if you sleep at eleven, the kopi or teh tarik at the mamak after five falls inside that window. Say honestly how many and when.
- The nap in the air-conditioned office. The Department of Health's sleep guide adds that a nap should also guard against getting chilled — keep a jacket on.
- Crunch season, exam season. Tiredness during a short high-pressure stretch and tiredness that has run for weeks with no clear reason are different things; for the second, see part 1.
💡 Remember: four things that can start tonight — a fixed wake-up time, at least 7–8 hours (AASM), a caffeine cut-off four to six hours before bed (HealthHub), and short naps. These are general daily arrangements, not a prescription for any pattern.
The words in this part
- 子午觉 (the midday and midnight sleep) — the Hong Kong Department of Health's sleep guide's phrase: be asleep at the midnight hour, and a short nap at the midday hour is also fine. 子时 is 11 pm to 1 am; 午时 is around noon.
- Caffeine cut-off (咖啡因截止时间) — HealthHub's wording: avoid caffeine four to six hours before bedtime. It is not a question of whether to give it up but of what time.
- Sleep duration (睡眠时数) — the AASM's figure is at least 7–8 hours; the NHS's tiredness page puts it as aiming for 6 to 9 hours. The two differ; this article does not merge them.
Frequently asked
Is it normal to feel especially tired at three in the afternoon? TCM theory has the 子午觉 idea — the Department of Health's sleep guide says a short nap at the midday hour is fine, 15 minutes to 1 hour. HealthHub's advice is to avoid daytime naps; if you must, within 30 to 45 minutes. Also look at how many hours you slept the night before, and whether there was caffeine after lunch (the table above). If the afternoon tiredness has run for weeks and affects your daily life, see part 1; if it affects driving or work safety, see part 5.
Is kopi a good way to stay awake? HealthHub's advice is to avoid caffeine four to six hours before bedtime; the AASM's wording is to avoid it in the afternoon or evening. Put another way, the morning cup and the evening cup mean different things for that night's sleep. No need to cut down before the consultation; log how many and when (the table in part 6).
