Insomnia: A Movie Replaying in Your Mind

The elders often say: "One sleepless night takes ten nights to recover." In the past, I took this for mere nagging, but now upon reflection, it carries a profound principle in traditional Chinese medicine (TCM) — when sleep goes wrong, it affects the whole body like pulling one strand of silk and the entire web moves. It truly isn't as simple as just surviving one sleepless night.

When your mind plays like a movie, scene after scene, and though your eyelids are heavy with drowsiness, your thoughts simply refuse to take their final bow — this kind of insomnia, from a TCM perspective, is not just a matter of "being unable to fall asleep." It is a sign that some internal mechanism in the body has lost its order, like boiling water bubbling and sputtering upward. Pressing down the lid won't help; you have to check the heat and the water level first.

I. Why Does the Heart Feel Restless in the Dead of Night?

When the brain plays like a movie, the most immediate sensation is that the heart cannot settle down. TCM describes this state as "the Heart failing to house the Spirit (Shen)." Among the five viscera, the Heart is likened to the sovereign of a state, governing consciousness, thought, and memory. During the day, this energy is dispersed outward amid busy activities; at night, it should return inward for rest. But if the pathway between the Heart and Kidney is not smooth, fire qi floats upward while the lower body feels empty, leaving the mind with no place to settle. The Heart belongs to Fire, the Kidney to Water. In normal conditions, Water and Fire restrain each other, so the Heart is neither hyperactive nor deficient. Think about it — when you toss and turn in the middle of the night, is it because you have been overthinking too much during the day and exhausting your mind?

Hyperactivity of Heart Fire alone leaves the Spirit uneasy — this is the most common pattern. People who are thoughtful by nature and often take on many responsibilities tend to end up in this state: their minds stay tense during the day, and at night they refuse to let go. This kind of insomnia is often accompanied by waves of vexation, a dry mouth, and a scorching sensation in the palms and soles. If you examine further, a red tongue tip and yellow urine point even more strongly to Heart Fire hyperactivity. In TCM clinical practice, the goal is not to rush in and "extinguish the fire," but first to ask: why won't the fire die down? Is it because the Water is insufficient, or because another pathway has become blocked?

There is another type: the "movie" in the brain replays all the trivial unfinished business from the day, one item after another, over and over. In TCM, this is called "the Liver failing to house the Ethereal Soul (Hun)." The Liver governs free coursing and discharging, and its greatest fear is stagnation. When qi stagnation persists, it tends to transform into fire, which flares upward and disturbs the Heart and Mind. Such people may appear calm on the surface during the day, but inside they are holding back many unspoken words. Once they lie down, all those suppressed thoughts rise to the surface. Clinically, it is crucial to distinguish whether the chief complaint is vexation and dry mouth, or emotional oppression and hypochondriac distension — the treatment approaches for each are somewhat different.

There is also a pattern that many people overlook: the Spleen and Stomach. TCM has a saying: "When the Stomach is not harmonious, rest is disturbed." Although it is not explicitly stated, it is commonly seen in outpatient clinics: if dinner is too heavy, too greasy, or if one stays up late snacking and scrolling on a phone, the belly becomes bloated and full — how can one sleep soundly lying down when even turning over feels uncomfortable? The Spleen and Stomach belong to Earth, and the Heart belongs to Fire; Earth engenders Fire. When the Spleen and Stomach struggle to transport and transform, the production of qi and blood falls behind, and the Heart and Mind fail to receive adequate nourishment. Naturally, the Spirit cannot settle. The images in the mind may be blurry, yet the physical discomfort is very real.

II. Following the Meridian Clock to Tune into the Body's Rhythm

TCM's approach to insomnia — especially the "endless rumination" type where the mind plays like a movie — has always been inseparable from the meridian system and the twelve time periods (shichen). Each of the twelve regular meridians has its own "shift" during which qi and blood are at their most abundant. Identifying which meridian is dominant at the time of waking often reveals the body's most hidden messages.

The Zi hour to the Chou hour (11 PM to 3 AM) is the shift of the Gallbladder Meridian and the Liver Meridian. If you are still awake during this period, or if you fall asleep but wake easily, the Liver and Gallbladder deserve special attention. The Gallbladder Meridian starts at the outer canthus of the eye, winds around the sides of the head several times, then descends all the way to the dorsum of the foot. Notice that graying temples, migraine headaches, bitter taste, and dry throat all run along the Gallbladder Meridian's pathway. The Liver Meridian ascends from the dorsum of the foot along the inner thigh, passes around the genitalia, encircles the hypochondriac region, then rises to the vertex. If someone whose mind plays like a movie also feels distension or discomfort along the Liver Meridian's route — that is, the inner thigh or the lower abdomen — or has vague discomfort under the ribs, the possibility of Liver qi stagnation is even greater. By the Chou hour, according to traditional TCM theory, Liver blood needs to return and be stored. Only in deep sleep can blood return to the Liver for nourishment and storage, preparing the body for the next day. If you wake precisely at this time and your mind starts replaying old stories, it is indeed worth paying close attention to the Liver Meridian's free-coursing capacity.

The Yin hour to the Mao hour (3 AM to 7 AM) belongs to the Lung Meridian and the Large Intestine Meridian. The Lung Meridian begins at the chest, runs along the inner arm down to the thumb, and is said to govern the qi of the entire body, "directing all vessels toward itself." If you wake regularly between three and four in the morning, accompanied by a thin sweat and a racing heart, you can no longer look only at the Heart and Liver. The Lung governs the skin and body hair, and also governs diffusion and descent. When the Lung qi fails to descend smoothly, it feels as if a small stone is pressing on the chest. Qi cannot move downward, and the Mind floats without a place to land. When the mind starts playing a movie at this hour — especially sad, brooding thoughts — TCM theory holds that the Lung corresponds to grief. In such cases, the diagnostic perspective should broaden to include the Lung.

In TCM clinical practice, pressing and kneading acupoints and applying moxibustion to specific areas are common external treatment methods. However, these procedures — especially point selection and technique — must be determined by a licensed TCM practitioner based on an individual's constitution. Performing them on oneself can easily do more harm than good, and this must be kept firmly in mind. The true foundation of time-based health maintenance lies in daily routine: during the Hai hour (9 PM to 11 PM), the Sanjiao (Triple Energizer) Meridian is on duty. At this time, one should gradually slow down, set down the phone, dim the lights, and allow the body's qi mechanism to begin drawing inward, preparing for sleep at the Zi hour. If you are in the habit of scrolling through short videos or replying to messages at this hour, your Heart and Mind remain engaged with the external world, and by the Zi hour, you simply cannot pull them back.

Heart-Kidney Non-Interaction and Malnourishment of the Spirit

For older people or those who have been chronically overworked, the movie-in-the-mind type of insomnia often has a different underlying foundation. Heart Fire stays above and cannot descend; Kidney Water stays below and cannot ascend. The Heart and Kidney are separated by a mountain, and Yin and Yang cannot meet — this is called Heart-Kidney non-interaction. During the day, there is palpitation and poor memory; at night, sleep is light and dreams are profuse. The moment the eyes close, past events appear vividly before them. In this pattern, the focus should fall on accompanying signs such as soreness and weakness of the lower back and knees, heat in the palms and soles, and tinnitus that hums like cicadas. Simply clearing Heart Fire often has no effect. It is better to widen the view and regulate the whole body's yin-yang connection.

People with qi and blood deficiency also often fail to find peace at night. The Mind depends on blood for nourishment; when blood is sufficient, the Spirit has the strength to reside steadily. If overthinking has consumed Heart blood, or if old age and frailty have gradually diminished qi and blood, the Mind is left without support — like a bridge without pilings, swaying with every gust of wind. People with this kind of insomnia tend to wake easily from dreams, feel groggy and heavy-headed during the day, have a pallid complexion, and a pale tongue and lips. Clinically, one must first distinguish whether the primary issue is Heart Fire or insufficiency of qi and blood, as the treatment approaches differ — this point cannot be overlooked.

Spleen-Stomach Disharmony and Dietary Impairment

When it comes to insomnia caused by the Spleen and Stomach, how dinner is eaten becomes a real subject of study. The elders often say, "Eat a good breakfast, a satisfying lunch, and a light dinner." There is indeed wisdom in this. After a whole day of transporting and transforming, the Spleen and Stomach should gradually rest in the evening. If you pile in rich meats and heavy dishes, they have no choice but to work overtime. When the body's qi and blood are busy digesting food, how much energy is left to nurture the Mind? As soon as you lie down, the belly is bloated and the mind is still playing a movie — and that movie is usually a jumbled, illogical stream of fragments. If you also have a habit of strong tea, coffee, or alcohol before bed, you are adding fuel to the fire.

As for dietary care, dinner should be light, soft, easy to digest, and moderate in quantity — about seven-tenths full. Coarse grains and miscellaneous cereals can be used in appropriate amounts. Medicinal foods that share the dual nature of medicine and food — such as longan, lotus seeds, red dates, and sour jujube kernels — can be used sparingly in daily meals, such as adding a few to porridge. However, the specific preparation should be determined by a licensed TCM practitioner after assessing your constitution; it is not recommended to copy someone else's regimen. If you can also keep regular meal times and avoid excessive hunger or fullness, the Spleen and Stomach will establish their own rhythm, and your nights will become noticeably more peaceful.

Emotional Frustration and Self-Guidance

Thinking carefully, the word "playing" in "the mind plays like a movie" is quite vivid — the movie is watched by the person, but the plot is beyond the person's control. When it reaches a scene that makes you toss and turn, your heart tightens, and all sleepiness vanishes. This is what it means to be "led around by the heart." Emotional influence on sleep accounts for half of all insomnia.

The old saying goes, "A broad heart makes the illness retreat by a foot." Does it hold true? From a TCM perspective, emotions directly affect the movement of qi. Anger makes qi rise; brooding makes qi bind; grief makes qi dissipate; fear makes qi descend. Once qi becomes disordered, the functions of the viscera follow suit, and the Mind is the first to suffer. Many people with long-term insomnia always hold some unresolved matter in their hearts. The harder they try not to think about it, the more it circles in the mind. In such situations, rather than fighting it, a better approach is to try a different method: half an hour before bed, take several deep abdominal breaths, focus attention on the rising and falling of the belly, and allow thoughts to come and go without chasing them. This is a form of daoyin (guiding and inducing qi) — a method commonly used in TCM health cultivation to rein in the Mind. As for how to adapt it to your own situation, the same old advice holds: talk it over with a licensed TCM practitioner.

Emotional guidance during the day deserves equal attention. When the morning sunlight is good, go out for a walk and get some sunshine, allowing yang qi to rise and activate the sinews and bones, which also smooths the movement of qi and blood. Exercise need not take any particular form — walking, Baduanjin (Eight Pieces of Brocade), or Taiji (Tai Chi) are all fine. The key is to let yourself relax. Don't bottle up emotions; you can keep a journal, talk with friends, and disperse the qi that has become blocked. TCM theory states: "The Liver delights in free expression and hates depression." When emotions run smoothly, Liver qi is released, and only then can the Mind find a place to rest at night.

Closing Thoughts

Have you ever considered that insomnia — a movie replaying in your mind — might be far more than just "not being able to sleep"? It may be your body's way of telling you that the Mind needs rest, Liver Fire needs to be quelled, and the Spleen and Stomach need a lighter load. Find a licensed TCM practitioner you can trust, receive a proper pattern differentiation, and then adjust your daily routine in harmony with the meridian clock. Go slowly — your body's rhythm will eventually return to its original state.
