What Primary Snoring Is
Snoring is the sound produced by the vibration of upper airway structures during sleep — primarily the soft palate and uvula, but also the base of the tongue, the lateral pharyngeal walls, and, less frequently, the epiglottis. Primary (or simple) snoring is defined as habitual snoring without evidence of obstructive sleep apnea (AHI <5/h on polysomnography) and without sleep fragmentation or daytime hypersomnolence.
Snoring habitually affects 44% of men and 28% of adult women. Aggravating factors include: obesity (especially cervical adiposity), supine position, alcohol and sedative consumption at night, nasal obstruction, hypothyroidism, and smoking. Although primary snoring does not cause direct cardiovascular risk (unlike OSA), its impact is significant: compromised sleep quality of the partner, marital conflict, social embarrassment, and sleepiness in the affected person who shares a bedroom.
Conventional Treatments
Primary snoring is treated with lifestyle modifications, mechanical devices, and, in selected cases, surgery. Unlike OSA, CPAP is not indicated for snoring without apnea.
TREATMENTS FOR PRIMARY SNORING
| INTERVENTION | MECHANISM | EFFICACY |
|---|---|---|
| Lateral positioning | Prevents tongue / palate from falling back | Moderate; positional vests or pillows |
| Weight loss | Reduces pharyngeal adiposity | High — 10% weight reduction lowers snoring by 30–40% |
| Reduce nighttime alcohol | Alcohol relaxes pharyngeal musculature | Simple and effective if main cause |
| Intraoral appliance (IOA) | Protrudes the mandible → opens the pharynx | Good efficacy; cost; variable tolerance |
| Palatal surgery (LAUP/UPPP) | Resects/remodels palate and uvula | Effective in 50%; irreversible; possible long-term worsening |
| Palatal radiofrequency | Stiffens the palate via controlled fibrosis | Less invasive; temporary effect (1–2 years) |
How Acupuncture Works in Snoring
Acupuncture acts on primary snoring through a mechanism of increased tone of the palatopharyngeal musculature — especially the tensor veli palatini and the muscle of the uvula — reducing the amplitude of vibration during sleep.
Mechanism of Action in Snoring
CV-24 — Hypoglossal Nerve and Genioglossus
Local somatosensory stimulation in the mentolabial region → brainstem reflex modulation of hypoglossal motor output → increased tone of the genioglossus during sleep; reduces the posterior fall of the tongue that narrows the oropharynx.
ST-9 / LI-18 — Palatal Musculature
Lateral cervical stimulation → pharyngeal nerves (IX and X) → increased tone of the tensor veli palatini and the muscle of the uvula → lower amplitude of palatal vibration.
LI-20 — Nasal Decongestion
Reduction of nasal resistance → improved nasal flow → reduced mouth breathing during sleep → less vibration of oropharyngeal structures (snoring is more intense with mouth breathing).
ST-36 + SP-6 — Metabolic Regulation
Improved insulin sensitivity and modulation of lipid metabolism → reduction of peripharyngeal adiposity in the long term → less extrinsic pharyngeal compression.

Modern Approach: Medical Acupuncture in Snoring
CLINICAL PROTOCOL IN PRIMARY SNORING
| PARAMETER | SPECIFICATION | NOTE |
|---|---|---|
| Main points | CV-24 + LI-20 + ST-36 bilateral | Hypoglossal + nasal + metabolic |
| Auxiliary points | SP-6 + ST-9 (with caution) | Metabolic + palatal |
| Frequency | 2 sessions/week for 8 weeks | SnoreLab for monitoring |
| Maintenance | 1 session/month | Reinforcement of palatal tone |
| Combination | + weight loss + positioning | Synergistic multimodal effect |
| OSA ruled out | Mandatory before starting | Polysomnography or screening oximetry |
When to See a Medical Acupuncturist
Indication for Acupuncture
- Confirmed primary snoring (OSA ruled out)
- Impact on the couple — partner with fragmented sleep
- Refusal or intolerance of the intraoral appliance
- Before considering palatal surgery (reversible)
- Snoring worsened by recent weight gain
Investigate Beforehand
- Polysomnography or oximetry to rule out OSA
- Excessive daytime sleepiness: OSA likely
- Witnessed apneas: OSA until proven otherwise
- Resistant hypertension + snoring: severe OSA highly likely
Frequently Asked Questions
Frequently Asked Questions
Acupuncture reduces snoring while treatment is active and for a few weeks afterward, but it does not produce a permanent structural change like surgery. Monthly maintenance sessions are needed to preserve the benefit. For a permanent result, surgery or intraoral devices are more definitive.
On average 8 to 10 sessions over 5 weeks. Perceptible improvement usually occurs after the 4th or 5th session. Use of a recording app (SnoreLab, for example) allows objective tracking of the progress.
Acupuncture is a less intimidating option than polysomnography or surgery, and can be the first step to engage the partner in treatment. However, it is important that the medical acupuncturist perform a basic OSA screening before starting — untreated apneas have serious cardiovascular consequences.
Snoring is common in pregnancy due to nasal congestion and weight gain. Acupuncture can be performed during pregnancy by an experienced medical acupuncturist, with adapted technique and avoiding traditionally contraindicated points (LI-4, SP-6, BL-60, BL-67, GB-21, lower-abdomen points) — safety depends on individual evaluation and on agreement with the obstetrician. Specific evidence for snoring in pregnancy is limited, and snoring of abrupt onset or worsening in the 2nd–3rd trimester requires screening for preeclampsia and gestational OSA before starting symptomatic treatment.
