Trouble Sleeping in Winter? How Traditional Chinese Medicine Looks at Sleep
If you have trouble sleeping in winter, the calendar may be part of the story. The sun sets before 5:05 PM in Halifax this month and before 4:35 PM by early December. Long dark evenings can leave the body unsure when the day is over, and many people find they fall asleep late, wake in the night, or feel unrefreshed in the morning.
Traditional Chinese Medicine (TCM) has looked at sleep for a very long time, and it asks more than "how many hours?"
How TCM Sees Sleep
In TCM, the Heart houses the Shen (spirit or mind). At night Shen is meant to settle into the Heart, supported by Yin (the cooling, calming, nourishing side of the body). When Yin is short, or something stirs the Heart, Shen stays restless and sleep suffers.
The Heart is one of the five zang organs; see our zang fu organs guide. Related: TCM organs and emotions.
These are TCM patterns, not medical diagnoses. Three come up often in winter:
TCM pattern | Typical signs | Tongue |
Heart and Kidney not communicating | Hard to fall asleep, hot palms and soles, night sweats, dry mouth, racing thoughts | Red, especially at the tip, with little coating |
Heart and Spleen deficiency | Wake easily, vivid dreams, tired, poor appetite, forgetful | Pale with thin white coating |
Liver Qi stagnation with heat | Irritable, red eyes, bitter taste, waking between 1 and 3 AM, stress on the mind | Red edges, yellow coating |
Many people are a blend. If your trouble sleeping in winter comes with hot feet that stick out of the covers, the first pattern may lead. If stress keeps you awake, the third is a more likely fit.
What People Often Describe
Lying awake for a long time before sleep comes
Waking at the same hour each night
Waking feeling as if they have not slept
Dreams that feel busy or vivid
Being tired and foggy all day, yet wired at bedtime
What the Research Says
A 2026 meta-analysis in Frontiers in Neurology (Li and colleagues) pooled 18 randomized trials with 1,767 people with chronic primary insomnia. The authors found that acupuncture helped with both nighttime sleep and daytime problems such as memory and cognition. They also note that the results should be read with care, because the studies varied and many were short.
That research is about insomnia in general, not winter sleep specifically, so I share it as context rather than a promise.
What an Acupuncture Visit Involves
A first visit begins with your sleep story: when you fall asleep, when you wake, what your evenings look like and how you feel during the day. I look at your tongue and feel your pulse. Treatment uses fine, sterile, single-use needles, and the plan is tailored to the pattern we find. If your sleep has not responded to earlier acupuncture, my article on why acupuncture may not seem to work explains what may be missing.
Two Things You Can Try at Home
1. Press Heart 7 (Shenmen) before bed. Turn one palm up and find the crease where the hand meets the wrist. On the little-finger side, a firm cord (tendon) runs up the forearm. The point sits on the crease, in the small hollow on the thumb side of that cord. Self-check: the cord stands out when you make a fist and bend your wrist toward you, and the hollow beside it is often slightly tender. Press firmly but comfortably for one to two minutes on each wrist, breathing slowly.
2. Set a winter rhythm. Keep the same wake-up time every day, get outside early for light, and switch to warm, dim lamps after sunset. Many people find a steady rhythm helps their body understand the long dark evening is not a reason to stay alert.
If worry keeps you awake, see Acupuncture for Anxiety in Halifax. If restlessness and poor focus are part of it, see Acupuncture for Adult ADHD in Halifax.
When to See a Doctor
See your family doctor or registered practitioner if:
Poor sleep has lasted more than a few weeks, or happens most nights
You snore loudly, gasp or stop breathing during sleep
You feel sleepy while driving or at work
You have restless or uncomfortable legs at night
Low mood, anxiety or worry is part of the picture
If you have thoughts of harming yourself or ending your life, call or text 9-8-8 any time, anywhere in Canada. If you are in immediate danger, call 911. Please do not stop or change any medication or sleep aid without talking to the prescriber.
