The most effective way to stop someone from snoring depends on what’s causing it, but the simplest starting point is getting them off their back. Sleeping on the side reduces snoring time by roughly 60% in position-dependent snorers. Beyond that, solutions range from lifestyle changes and oral devices to medical treatment for more serious cases.
Snoring happens when air flows past relaxed tissues in the throat, tongue, and soft palate during sleep. As you move from light to deep sleep, these muscles go slack, partially narrowing the airway. The narrower the passage, the more forcefully air moves through it, and the louder the vibration gets.
Start With Sleep Position
Back sleeping is the single biggest positional contributor to snoring. When someone lies face-up, gravity pulls the tongue and soft palate backward, narrowing the airway more than any other position. Switching to side sleeping cuts the total snoring rate roughly in half, based on sleep lab measurements showing a drop from about 37% of the night spent snoring to around 16%.
For someone who rolls onto their back during the night, a few tricks help maintain a lateral position. The classic approach is sewing a tennis ball into the back of a sleep shirt, which creates enough discomfort to trigger a roll without waking the person. Wedge pillows designed for side sleeping work similarly. For persistent cases, vest-type positional devices with inflatable chambers keep the sleeper on their side throughout the night and have been shown to reduce snoring without significant side effects.
Lifestyle Changes That Make a Real Difference
Neck circumference is one of the strongest predictors of snoring severity. Extra tissue around the throat physically compresses the airway, and men with necks larger than 17 inches (16 inches for women) face significantly higher risk of loud, habitual snoring. Losing even 5 to 10% of body weight can decrease both snoring frequency and intensity. For someone weighing 200 pounds, that’s 10 to 20 pounds, often enough to noticeably thin the tissue pressing on the airway.
Alcohol is another major trigger. It relaxes throat muscles beyond their normal resting state, making the airway more collapsible. The timing matters: stopping all alcohol at least four hours before bed gives the body enough time to metabolize it so the sedative effect doesn’t reach the throat muscles during sleep. This alone can eliminate snoring in people who only snore after drinking.
Nasal congestion from allergies or a cold forces mouth breathing, which directs all airflow over the soft palate and amplifies vibration. Treating the underlying congestion with saline rinses, allergy medication, or a humidifier in dry climates can reduce or stop snoring that’s nose-related.
Over-the-Counter Devices
Nasal dilators come in two forms: external strips that stick to the outside of the nose and internal clips or cones that sit inside the nostrils. Both widen the nasal passages to improve airflow. In a head-to-head comparison of 41 snorers, both types significantly reduced snoring time and improved sleep quality, but internal dilators worked for a larger number of people and produced better sleep quality scores overall. These devices only help when the snoring originates from nasal obstruction. If the vibration comes from the throat (which is more common), nasal dilators won’t do much.
Mandibular advancement devices, sometimes called anti-snoring mouthpieces, push the lower jaw slightly forward during sleep. This opens up the space behind the tongue where most snoring vibration occurs. Custom-fitted versions from a dentist offer a more precise fit and adjustable advancement, while boil-and-bite versions sold online are cheaper but less comfortable. Many users report less snoring, better sleep quality, and reduced daytime fatigue. Jaw soreness and excess saliva are common in the first week or two but usually fade.
When Snoring Signals Something More Serious
Not all snoring is benign. Obstructive sleep apnea (OSA) involves the airway completely collapsing during sleep, cutting off breathing for seconds at a time, sometimes hundreds of times per night. Clinicians screen for it using a set of eight risk factors: loud snoring (audible through closed doors), daytime tiredness or fatigue, observed pauses in breathing during sleep, high blood pressure, elevated BMI, age over 50, large neck circumference, and male sex. The more of these that apply, the higher the likelihood of sleep apnea rather than simple snoring.
The key warning signs that separate sleep apnea from ordinary snoring are gasping or choking sounds during sleep and excessive daytime sleepiness despite a full night in bed. If the snorer wakes up feeling unrefreshed no matter how long they sleep, or if a bed partner notices actual pauses in breathing, a sleep study is the next step. Left untreated, OSA raises the risk of heart disease, stroke, and type 2 diabetes.
Medical Treatment for Persistent Snoring
CPAP (continuous positive airway pressure) is the standard treatment when sleep apnea is confirmed. The machine delivers a gentle stream of air through a mask, keeping the airway open and eliminating both the breathing pauses and the snoring sound entirely. It works from the first night. The challenge is comfort and compliance: some people struggle to tolerate the mask, though modern designs are smaller and quieter than older models.
For snoring without sleep apnea, or mild sleep apnea where CPAP feels like overkill, surgical options exist. Laser-assisted uvulopalatoplasty trims and reshapes the uvula and soft palate to reduce the tissue that vibrates. It’s performed in stages under local anesthesia as an outpatient procedure, with an 85% success rate for reducing or eliminating snoring across studies of over 450 patients. Recovery involves a sore throat for one to two weeks. More extensive surgery (uvulopalatopharyngoplasty) removes additional throat tissue and is typically reserved for more severe obstruction.
What the Bed Partner Can Do Right Now
While working on longer-term solutions, the person sharing the bed needs sleep too. Foam or silicone earplugs carry noise reduction ratings between 22 and 33 decibels. Since snoring typically ranges from 40 to 70 decibels, earplugs won’t block it completely, but they can bring it below the threshold that triggers waking. For stronger coverage, pairing earplugs with a white noise machine helps mask the irregular, rumbling quality of snoring that makes it so disruptive. Pink noise, which filters out the harsher high-frequency sounds and resembles steady rainfall, tends to be more pleasant for sleeping than pure white noise.
Gently nudging the snorer onto their side often produces immediate, if temporary, relief. A light touch on the shoulder or hip is usually enough to trigger a position change without fully waking them. Over time, combining this with a positional sleep aid removes the need for nightly nudging.
