What Causes Insomnia in Chinese Medicine?

Insomnia is a name for a symptom. It tells you that you cannot sleep. It does not tell you why. In Chinese medicine the why is the whole point, and two people with the same sleepless nights can need completely different treatment. Here is how that works, what the research says about it, and how to start finding the pattern behind your own nights.

What causes insomnia in Chinese medicine?

A new patient told me recently that she had been diagnosed with insomnia, and her doctor was not sure which medication to try. There were many options and no clear way to choose between them. I told her I do not care about the diagnosis unless it leads to effective treatment. I care about the reasons she cannot sleep.

Chinese medicine calls those reasons patterns. When researchers at the University of Hong Kong pooled 103 studies covering 9,499 people with insomnia, they found 69 different Chinese medicine patterns in use. The three most common covered about half the patients, and the top ten covered 77.4%.^[1] A 2025 study of 468 insomnia patients found the same spread, with a pattern called Heart and Spleen deficiency the most common at 31.6%, and the pattern a person had varied with their age, work, blood pressure and diabetes history.^[2]

So I am not saying you do not have insomnia, but what we actually need to know is the pattern behind it. If you want a map of the common sleep problems first, my page for people who cannot sleep sorts them by when and how the night goes wrong. Learning to read your own pattern is also a big part of what we do inside Gut Brain Synchrony.

How does Chinese medicine diagnose insomnia?

The classical method has four parts: looking, which includes the tongue; listening and smelling; asking; and touching, which includes the pulse. The questions go well beyond sleep. When do you wake? What is on your mind when you do? Are you hot at night? Do you dream a lot? How is your digestion, your energy, your period?

Those answers are the evidence. In the Hong Kong review, the most common features used to tell the insomnia patterns apart were excessive dreaming, dizziness, a red tongue and a thin, fine pulse.^[1]

This way of sorting patients is now formally recognized. The latest edition of the World Health Organization’s International Classification of Diseases, ICD-11, includes a supplementary chapter on traditional medicine diagnostic patterns, Chinese medicine among them.^[3]

Which insomnia pattern is keeping you awake?

Here are the four patterns I named in the video, each with the biomedical idea I think sits closest to it. Those pairings are my own bridge between the two systems, a way of explaining the pattern to someone trained in Western terms. No study has tested them as pairs. What the research does show is that each of the Western halves is tied to poor sleep.

Liver qi stagnation insomnia: the mind that will not switch off

You lie awake with a racing mind, stressed and tense, unable to switch off. In Chinese medicine the Liver keeps qi moving smoothly, and stress and held-in emotion bind it up. I think of this pattern as autonomic dysfunction, a nervous system stuck in its daytime gear.

There is support for that picture. In a sleep lab study, 12 people with objectively measured insomnia had faster heart rates than matched good sleepers in every stage of sleep, and their heart rhythm showed the signature of more sympathetic, fight-or-flight activity.^[4] A 2022 meta-analysis of 17 studies, though, did not confirm that heart rate variability is reliably lower in insomnia as a whole.^[5] That fits the pattern view: a wound-up nervous system drives some people’s insomnia, not everyone’s.

Heart blood deficiency: tired, pale and dreaming

In Chinese medicine the Heart houses the mind, and blood anchors it at night. When blood runs low, sleep turns light and full of dreams, often with fatigue, palpitations, a pale face and poor memory. The closest Western idea is anemia.

A 2026 review found iron deficiency anemia consistently linked to worse sleep quality, shorter sleep, more time to fall asleep and less deep sleep, and found that iron treatment reduced restless legs and sleep disturbance in most of the trials it assessed.^[6] In a study comparing 170 people with iron deficiency anemia to 170 healthy people, the anemic group scored higher for anxiety and insomnia.^[7]

Yin deficiency: heat that wakes you up

Yin is the cooling, moistening side of the body. When it runs short, heat rises at night: hot flashes, night sweats, a dry mouth, waking at the same hour. I connect this pattern to endocrine change, and perimenopause is the clearest example.

In a survey of 982 California women aged 35 to 65, chronic insomnia affected 36.5% before menopause, 56.6% during perimenopause and 50.7% after. Among peri- and postmenopausal women with severe hot flashes, insomnia symptoms passed 80%.^[8]

Blood stasis with heat: pain and inflammation

When an old injury, chronic inflammation or a lingering infection keeps the body inflamed, Chinese medicine describes blood that is not moving, with heat trapped in it. Pain is the main clue: you wake because something hurts.

The same California study found chronic pain was significantly associated with chronic insomnia.^[8] And a meta-analysis of 72 studies, more than 50,000 people, found that disturbed sleep goes with higher levels of the inflammatory markers C-reactive protein and interleukin-6.^[9] Pain keeps people awake, and disturbed sleep travels with inflammation.

Snoring is a different question

If you wake yourself snoring, the pattern may be in your airway. Sleep apnea was another factor tied to chronic insomnia in the California data.^[8] A 2026 meta-analysis put the share of patients who have both insomnia and obstructive sleep apnea at 30%, with more brief arousals, more time awake in the night and less efficient sleep than either condition alone.^[10] That is a pattern a sleep study can see, and it needs its own plan.

How accurate is Chinese medicine diagnosis?

It depends on training, and it is a fair question to ask. When three experienced practitioners examined the same 40 patients with rheumatoid arthritis separately, they agreed on the Chinese medicine diagnosis only 31.7% of the time, though each one’s herbal prescription matched the textbook treatment for the diagnosis they gave 91.7% of the time.^[11]

Agreement can be trained. When ten licensed acupuncturists used a structured questionnaire and calibrated their diagnoses together, the correlation between their diagnoses rose from 0.112 to 0.618.^[12] This is the reason researchers are now building scored, evidence-based rules for each pattern.^[3]

Does treating the pattern work? In a placebo-controlled trial of 116 adults with moderate to severe insomnia, three clinicians each prescribed herbs for every patient according to that patient’s pattern. After four weeks the herbal group slept about 0.6 hours longer than the placebo group and improved more on the Pittsburgh Sleep Quality Index. The patterns the clinicians found most often were blood deficiency and Liver stagnation. Their prescriptions stayed consistent even when the individual herbs varied, and side effects were mild and unrelated to treatment.^[13] In a large back pain trial, by contrast, acupuncture tailored to each patient did no better than a standard point prescription or simulated needling.^[14]

Does Chinese medicine treat the cause of insomnia?

The goal in Chinese medicine is to change the pattern so that good sleep holds on its own, not to manage the symptom night after night. A mature medical paradigm treats causes.

Sometimes Western medicine does this well, and insomnia care is a good example. The American College of Physicians recommends cognitive behavioral therapy for insomnia, CBT-I, as the first treatment for every adult with chronic insomnia, with medication considered only if that alone does not work.^[15] CBT-I works on the habits and the arousal that keep insomnia going. A systematic review comparing it with sleeping pills found benzodiazepines may work better in the short term, while CBT-I did better over the long term and its effects may last longer.^[16]

Sleeping pills do help many people sleep. The average effect is modest, though. In a meta-analysis of 24 short-term trials in 2,417 people aged 60 and over, sedative hypnotics added about 25 minutes of sleep a night compared with placebo, and the authors judged the benefit small.^[17]

So instead of only asking how to get you to sleep tonight, we ask the question that leads somewhere: what pattern is keeping you awake?

How to find the pattern behind your insomnia

Then bring your notes to a practitioner who will read the whole picture with you.

Chinese medicine for sleeping problems, answered

What is liver qi stagnation insomnia?

It is insomnia driven by stress and held-in tension. The mind races, the body is tense, and switching off at night feels impossible. Chinese medicine treats it by getting qi moving again rather than by sedating you.

Are there Chinese herbs for sleep problems?

Yes, but Chinese medicine does not have one sleep herb. The formula follows the pattern, so a depleted, blood-deficient sleeper and a stressed, overheated one get different prescriptions. In the trial above, each patient’s prescription was built around their own pattern.^[13]

Can you have heart blood deficiency and liver qi stagnation together?

Yes, and it is common. Patterns overlap in real people, which the Hong Kong review also found.^[1] Blood deficiency and Liver stagnation were the two patterns found most often in the herbal trial.

Your insomnia is real. The pattern behind it is what tells us how to fix it.
