Best Sleeping Position for Snoring: Side, Back or Stomach?
If you snore, the way you lie down may matter more than any gadget. Here is what studies show about side, back and stomach sleeping, how much raising your head helps, and practical ways to stay off your back all night.
Why position changes snoring
Snoring is the sound of relaxed tissue in the throat vibrating as air squeezes through a narrowed airway. When you lie on your back, gravity pulls the jaw, tongue and soft palate backward, and the space behind the tongue gets smaller. On your side, those structures fall sideways instead, and the airway tends to stay more open.
That is why position is often the first thing sleep specialists ask about. It costs nothing to change, and for many people it is the main reason snoring comes and goes from night to night.
The best sleeping position for snoring: on your side
The clearest evidence comes from a sleep-lab study of 72 habitual snorers who had a full overnight sleep study (polysomnography). Among people who snored but did not have sleep apnea, most snored less on their side, both in how long they snored and in how loud it was. People with obstructive sleep apnea were more mixed: some of them kept snoring even on their side.
So for simple snoring, side sleeping is the best sleeping position for snoring you can try tonight. The Sleep Foundation also lists side sleeping as the position that tends to cause the fewest breathing problems at night, and the one most often recommended during pregnancy.
Left or right side?
For snoring, there is no strong evidence that one side beats the other. Pick the side that is comfortable for your shoulders and neck. A pillow that fills the gap between your shoulder and head keeps your neck straight, and a pillow between the knees makes the position easier to hold.
Back, side or stomach: how they compare
| Position | Effect on snoring | Good to know |
|---|---|---|
| Side | Usually the least snoring | Can strain shoulders; a supportive pillow helps |
| Back, flat | Usually the most snoring | Also worse for reflux and for many people with sleep apnea |
| Back, head raised | Often better than flat | Raise the upper body, not just the head |
| Stomach | Mixed research | Twists the neck; not ideal for most people |
Stomach sleeping keeps the tongue from falling back, but research on it is mixed and it forces your head to turn to one side for hours. Most people are better off learning to sleep on their side.
Is your snoring positional?
Many people snore mainly on their back. In sleep apnea this pattern is so common that it has its own name, positional obstructive sleep apnea: breathing problems on the back are at least twice as frequent as in other positions. In a 2025 analysis of 1,870 people from a large community study, 62% of those with sleep apnea had this positional pattern.
You can check your own pattern in a few ways:
- Ask your partner whether the snoring stops when you roll over.
- Record a few nights with a phone app and note which way you fell asleep.
- Notice whether you wake with a dry mouth after nights on your back.
If your snoring is loud in every position, position alone will probably not fix it. That is a reason to look at other causes, such as a blocked nose, alcohol before bed or sleep apnea.
Raising your head: how much and how
If you cannot sleep on your side, the next best option is to sleep on your back with your upper body slightly raised. In a study of 52 people with sleep apnea, raising the head of the bed by just 7.5 degrees lowered the median number of breathing events per hour from 15.7 to 10.7, without changing sleep structure. The study looked at sleep apnea, not simple snoring, but the mechanism is the same: less of the airway collapses backward.
- Raise the whole upper body. Blocks under the head end of the bed, a wedge pillow or an adjustable base all tilt the torso.
- Avoid a tall stack of pillows. It bends the neck forward and can narrow the airway instead of opening it.
- Start small. A gentle angle is easier to sleep on and may be enough.
How to stay on your side all night
Falling asleep on your side is easy. Staying there is the hard part, because most people change position many times a night without knowing it.
- Use a body pillow behind your back or in front of your chest so rolling over feels less natural.
- Try the tennis ball trick, with realistic expectations. A ball sewn into the back of a shirt makes lying on your back uncomfortable. It can work in the short term, but in one follow-up study only 6% of people were still using it about two and a half years later, mostly because it was too uncomfortable.
- Consider a positional device. Small worn devices that vibrate gently when you roll onto your back are a more comfortable version of the same idea. Ask your doctor if your snoring is linked to sleep apnea.
- Train the habit. Some people in the tennis ball study stopped using it because they had learned to avoid their back. Repetition helps.
Position is one of several changes that can help. For the full list, including nasal strips, mouth exercises and mouthpieces, see our guide on how to stop snoring or the comparison of anti-snoring devices.
When position is not enough
If you snore loudly on your side as well as your back, if your partner notices pauses in your breathing, or if you are very sleepy during the day, position changes may only hide the problem. Learn the difference in snoring vs sleep apnea, and talk to a doctor about a sleep study.
Not just tape.
A mouth band that understands your night.
The hard part of positional snoring is that you never know when you rolled onto your back. Zzip is being developed to hear snoring as it starts and respond with a gentle vibration designed to nudge you to change position without waking you.

- Keeps your mouth closed, comfortablyA flexible silicone body with an integrated, skin-friendly adhesive, shaped around the mouth.
- Follows every breathA thermistor near the nose counts each breathing cycle directly from the warm and cool air of your breath.
- Hears snoring and respondsA microphone detects snoring; a gentle vibration is designed to encourage you to change position without waking you.

If you are curious about mouth taping, Zzip is worth following: it is the version that shows you whether it actually works for you.
Zzip is a prototype in development. Features and measurement performance are being tested. It is not a medical device and does not diagnose or treat sleep apnea or any other condition.
Frequently asked questions
What is the best sleeping position to stop snoring?
For most people, sleeping on the side. Studies show that people who snore without sleep apnea usually snore less, and more quietly, on their side than on their back.
Why do I only snore on my back?
On your back, gravity pulls the tongue and soft palate toward the back of the throat and narrows the airway. If the snoring stops when you roll over, your snoring is likely positional.
Does sleeping with your head elevated help snoring?
It can. Raising the upper body slightly with a wedge or bed blocks reduced breathing events in a study of people with sleep apnea. Avoid stacking pillows, which bends the neck.
Does the tennis ball trick work for snoring?
It can keep you off your back, but most people stop using it because it is uncomfortable. Long-term use was very low in follow-up research.
Is sleeping on your stomach good for snoring?
The research is mixed. It may keep the airway more open for some people, but it strains the neck. Side sleeping is usually the better choice.
