Why waking up at night happens: a TCM view of sleep
It is 2 a.m. and you are wide awake again. You were tired enough to fall asleep, but staying asleep feels out of reach, and the worry about tomorrow starts to build.
You are not alone in this. Statistics Canada reported that nighttime insomnia symptoms rose from 16.8% in 2007-to-2009 to 23.8% in 2014-to-2015, an increase of 42%.
Many people describe the same frustration behind waking up at night: the mind will not settle, the body feels restless, or sleep comes in short pieces.
How TCM views sleep
In TCM, sleep is a time when yang activity quiets and yin takes over, allowing the mind, called Shen, to rest in the Heart. When that quieting does not happen fully, sleep may become light, broken, or restless.
TCM also teaches a traditional organ clock, in which each meridian has a two-hour period of stronger activity. This is a traditional teaching, not a modern scientific claim.
1 a.m. to 3 a.m. is linked with the Liver channel.
3 a.m. to 5 a.m. is linked with the Lung channel.
The Liver is said to store Blood and is emotionally connected to anger, so waking in that window may prompt questions about stress, tension, and unprocessed frustration.
Common TCM patterns behind broken sleep
A pattern is a way of grouping signs together in TCM. These are TCM concepts, not Western medical diagnoses.
Pattern | Signs you may notice | Tongue |
|---|---|---|
Liver fire disturbing the Heart | Restless, broken sleep; vivid dreams; feeling hot or irritable at night | Red, especially at the sides, with a yellow coating |
Heart and Kidney yin deficiency | Waking often; night heat or sweating; dry mouth at night; a sense of inner restlessness | Red with little coating |
Heart and Spleen deficiency | Light sleep; waking easily and struggling to drift back; tiredness through the day; dream-filled sleep | Pale and slightly swollen |
Two people can wake at the same hour for different reasons. I ask about dreams, temperature, thirst, mood, and digestion, rather than treating the clock alone as an answer.
What an acupuncture visit involves
Your first visit starts with listening. I ask when you wake, how long you stay awake, what helps, and what else is happening with pain, digestion, mood, and energy.
Intake: a detailed history of your sleep and general health, plus any medicines or supplements you take.
Tongue and pulse: I look at the tongue and feel the pulse at both wrists, as TCM uses these to help identify a pattern.
Treatment: very fine, sterile, single-use needles are placed gently at points chosen for your pattern, and you rest while they are in place.
Plan: we agree on a tailored plan and review how your sleep changes over time.
Research offers some encouragement. A 2025 systematic review in Frontiers in Neurology, with 757 people in 10 trials, found that acupuncture improved subjective sleep quality, reduced time spent awake after first falling asleep by about 18.5 minutes on average compared with sham acupuncture, and improved sleep efficiency.
Two things you can try at home
Press Shenmen (HT7). Find the crease across the inside of your wrist. On the little-finger side of that crease, feel for the thick cord that runs up your forearm; the point is in the small hollow on the thumb side of that cord, right on the crease itself, not a finger-width above or below it. Press firmly for 2 to 3 minutes, with some aching or tenderness but no pain, and check that you can feel the dip under your thumb. Skip this point if the skin there is peeling, blistering, broken, rashy, red, swollen, warm, or has pus.
Leave the bed if sleep does not return. If you have been awake for about 15 minutes and feel no closer to sleep, get up, go to another room, and return to bed only when you feel sleepy.

When to see a doctor
Broken sleep is common, but some signs need prompt medical attention. See your family doctor or registered practitioner if any of the following apply:
Your breathing stops and starts at night, or you make gasping, snorting, or choking noises, wake a lot, or snore loudly.
You regularly wake with soaking wet sheets, or you have night sweats and are losing weight for no reason.
You are peeing more than usual.
Changing your sleeping habits has not helped, you have had trouble sleeping for months, or broken sleep is making daily life hard to cope with.
Call 911 straight away if you have chest discomfort or pain with sweating, nausea, light-headedness, or shortness of breath.
Do not stop or change sleep medication, or any other prescribed medicine, without talking to the prescriber first.
If waking up at night has become your normal, you do not have to sort it out alone. We can look at your TCM pattern together and talk through whether acupuncture may help — you can book a consultation here.
