Why Do I Keep Waking Up at 1-3 AM?
There's a particular kind of insomnia that feels almost mechanical. You fall asleep fine. Then, like clockwork, your eyes open between 1 AM and 3 AM. You lie awake. If you fall back asleep at all, it's shallow, restless — the kind of sleep that leaves you groggy the next morning.
If this sounds familiar, you're not imagining it. In traditional Chinese medicine (TCM), this isn't random. It's tied to a very specific window of the body's internal clock.
Dr. Zuo Changbo, a well-known Chinese acupuncture clinician, has spent years treating exactly this pattern. And he's noticed two small but remarkably consistent clues in these patients — clues that point to a clear treatment approach.

The 1-3 AM Window and the Liver Meridian
In TCM's system of time-based organ cycles — known as the Na·Zi method (纳子法) — each two-hour window of the day is governed by one of the twelve meridians. The hours between 1 AM and 3 AM are the Chou Hour (丑时), and this belongs to the Liver Meridian (肝经).
So when a patient consistently wakes during these hours, a TCM practitioner first thinks of the liver. Not the physical organ alone, but the whole liver functional network — its energy flow, its ability to smooth and circulate qi, and its role in calming the nervous system.

Two Small Clues Your Body Is Telling You
Dr. Zuo observed that patients waking regularly between 1 and 3 AM tend to share two reproducible physical findings:
A tender point around Taichong (太冲) — specifically in the space between the Xingjian and Taichong acupoints, near the liver-meridian point on the top of the foot. Press it, and it's clearly uncomfortable.
A taut, tender cord at Tanzhong (膻中) — located on the front of your chest, along the midline. In healthy people, this area usually feels smooth and soft. In these patients, Dr. Zuo can often feel a thick, tender band — a "tendon knot" along a chest meridian that relates to the Pericardium (the Luo point region).
Neither of these finds is subtle in these patients — the tenderness appears with remarkable consistency.
The Approach: Releasing the Knot, Unblocking the Chest
Based on these two physical clues, Dr. Zuo uses a targeted acupuncture protocol:
- Taichong (太冲) below — a needle is placed at the liver meridian point on the foot to soothe and unblock liver qi.
- Tanzhong (膻)) above — a slightly thicker needle (about 0.25 mm) is inserted obliquely into the tender cord. The goal is to release the tendon knot, what Dr. Zuo calls "resolving the tendon keloid."
Why does this pairing work so well?
Needling Taichong addresses the liver qi directly at its source. Releasing the Tanzhong knot opens the chest and regulates qi — the classic TCM skill of wide-open heart qi. Together, they take a congested, stuck pattern and let it flow again. For patients who wake between 1 and 3 AM, Dr. Zuo reports very good results with exactly this combination.

A Clever Addition: The Yintang–Shangen Piercing
When it's helpful, Dr. Zuo adds a third technique — piercing the Yintang point (印堂), the midpoint between the eyebrows.
In classical acupuncture, Yintang is used for calming the mind (quiet spirit). But Dr. Zuo uses it differently: he threads the needle outward toward the Shangen (山根), the bridge of the nose — a method rooted in Face Mapping acupuncture (应象针灸为).
Here's the logic:
- The two eyebrows relate to the collarbones (clavicles)
- The Yintang point mirrors the Tiantu acupoint near the base of the throat
- The Shangen corresponds to the famous Tanzhong area at the sternum
- The tip of the nose corresponds to the Juiwei point below the chest (the sword-shaped process)
By piercing from Yintang through to Shangen, the practitioner can treat chest and qi-level issues through a far more accessible, finer map of the face. It's an elegant example of how TCM uses the body's structure as a living map.
What This Means for You
If you wake every night between 1 and 3 AM and struggle to get back to deep sleep, this pattern is worth considering:
A clear, testable idea: waking in the liver hours points toward liver-meridian or chest qi obstruction.
A repeatable medical finding: tenderness at Taichong and a taut cord at Tanzhong support the diagnosis and guide the needling.
A safe, drug-free option: hospital-based acupuncture sessions are done with disposable needles and customized to each patient.
For international patients, TCM acupuncture in China is widely available and relatively low-cost. A course is usually planned over multiple sessions, with the clinician adjusting the points based on your response.
