Yes, acupuncture commonly makes people feel sleepy, both during and after a session. In a large cross-sectional survey of patient experiences, 24.4% reported tiredness or drowsiness as a direct short-term reaction, while 79.1% reported feeling relaxed. Some people drift into a sleep-like state right on the treatment table. This drowsy, floaty feeling is so well-known among regular patients that it has its own informal name: “acu-stoned.”
Why Acupuncture Triggers Sleepiness
The drowsiness isn’t random. Acupuncture shifts your nervous system away from its alert, stress-ready mode and toward its rest-and-digest mode. Needle stimulation activates a network of brain regions that dial down stress hormones like cortisol while boosting calming chemical signals, including GABA (the same brain chemical targeted by anti-anxiety medications) and serotonin. At the same time, acupuncture activates nerve pathways in the brainstem that increase the activity of the vagus nerve, your body’s main “calm down” signal line. The result is a measurable decrease in your fight-or-flight response and a corresponding increase in the relaxation side of your nervous system.
There’s also a local chemical effect. When needles are inserted and rotated, they cause minor tissue disruption that releases adenosine, a compound your body naturally accumulates throughout the day to build sleep pressure. Researchers at the University of Rochester found a 24-fold rise in adenosine at the needle site during acupuncture in animal studies. Adenosine is the same molecule that caffeine blocks to keep you awake, so a surge of it helps explain the heavy, drowsy sensation many people feel.
On top of all this, acupuncture prompts the brain to release endorphins, your body’s natural opium-like compounds. Endorphins reduce pain perception and produce a warm, sedated feeling that reinforces the overall sleepiness.
What the Sleepiness Feels Like
Most people describe the sensation as a deep, pleasant relaxation rather than the grogginess you get from a bad night’s sleep. During the session itself, your limbs may feel heavy, your thoughts may slow, and you might lose track of time. Many patients fall fully asleep on the table and wake up feeling refreshed.
After the session, the feeling typically continues as a calm, slightly foggy state. You may feel like you’ve just woken from a long nap. For some people this lasts an hour or two; for others, it lingers through the rest of the day. First-time patients tend to experience it more intensely, likely because their nervous system isn’t accustomed to the shift. The calming aftereffects can persist for days in some cases, gradually transitioning from drowsiness into a general sense of improved well-being.
Not Everyone Reacts the Same Way
While sleepiness is one of the most common reactions, it’s not universal. In that same patient survey, about a third of people reported feeling energized rather than tired after their session. Which way you respond can depend on several factors: which acupuncture points are used, how stressed or sleep-deprived you were going in, and your individual nervous system sensitivity. Certain points are specifically chosen for their calming properties. The Yin Tang point, located between the eyebrows, is one of the most well-studied sedative points. A clinical trial on children undergoing medical procedures found that pressure on this point alone reduced anxiety by 9% compared to a sham treatment group.
Your practitioner’s goals for the session also matter. A treatment focused on pain relief or energy may use different point combinations than one aimed at calming anxiety or improving sleep, and the post-treatment sensation can vary accordingly.
Acupuncture for Sleep Problems
Because of its sedative effects, acupuncture is frequently used as a treatment for insomnia. The clinical picture here is more nuanced than the in-session drowsiness might suggest. A 2025 systematic review with meta-analysis in Frontiers in Neurology examined whether acupuncture actually improves measurable sleep outcomes in people with chronic insomnia. When researchers compared real acupuncture to sham acupuncture using objective tools like sleep monitors, the difference in total sleep time was not statistically significant. Neither manual acupuncture nor electroacupuncture outperformed sham treatments on that measure.
This doesn’t necessarily mean acupuncture is useless for sleep. The relaxation response is real and measurable, and many people with insomnia report subjective improvements in sleep quality. But the gap between “acupuncture makes me feel sleepy” and “acupuncture cures my insomnia” is wider than you might expect. The drowsiness you feel during and after a session is a genuine neurological event, though translating that into lasting changes in sleep architecture is a different, harder challenge.
Practical Tips for After Your Session
The drowsiness is significant enough that Cleveland Clinic recommends arranging a ride home from your appointments, especially the first one. If driving yourself is the only option, sit in the waiting room for five to ten minutes before getting behind the wheel. Nearly a quarter of patients experience drowsiness that could impair driving, so this isn’t an overly cautious suggestion.
Your practitioner may also recommend taking it easy for a day or two after each session. This doesn’t mean bed rest, just avoiding intense physical or mental demands while your body processes the treatment. Drink water, avoid alcohol, and let yourself rest if your body is asking for it. Many people find that leaning into the sleepiness rather than fighting it produces the best results, particularly if they’re getting acupuncture for stress, anxiety, or sleep-related concerns.
If you have afternoon or evening appointments, the timing can work in your favor. The post-session drowsiness can naturally transition into a good night’s sleep. Morning appointments, on the other hand, may leave you feeling sluggish for a few hours, so plan your day accordingly.
