How to Stop Snoring: The Complete Evidence-Based Guide

If you’re reading this at 2am — elbowed awake, banished to the sofa, or lying next to someone who sounds like a chainsaw — you want a straight answer, not a sales pitch. Here it is: snoring can almost always be reduced, and often stopped, but no single remedy works for everyone. The right fix depends on why you snore.

The good news is that the research is clearer than the adverts suggest. A handful of approaches have solid evidence behind them — side-sleeping, weight loss if you’re carrying extra weight, cutting evening alcohol, mouth exercises, dental devices and (for sleep apnoea) CPAP. Plenty of others, from chin straps to essential oils, have little or none.

This guide walks through all of it: what to try tonight, the long-term changes that matter most, a comparison of every option, and how to match a fix to your particular kind of snoring. If you want the background first, start with what causes snoring.

One principle underpins everything that follows. Snoring is the sound of air vibrating past relaxed, sagging tissue in a narrowed upper airway — so every genuine remedy works in one of two ways: it widens the airway (weight loss, position change, nasal treatment, devices, surgery) or it firms up the tissue so it vibrates less (mouth exercises, avoiding alcohol and sedatives). Anything that does neither is unlikely to help, however persuasive the advert.

Start tonight: three changes with evidence behind them

You don’t need to buy anything to make a difference tonight.

1. Sleep on your side. When you lie on your back, your tongue and soft palate fall backwards and narrow the airway. The NHS specifically recommends side-sleeping for snorers, and suggests practical aids such as a special pillow or bed wedge to help you stay there.^[1] A 2024 systematic review of nine studies found that snoring was longest and most severe when people slept on their backs, and least severe on their sides.^[2] Our sleeping position guide covers the techniques in detail.

2. Skip alcohol in the evening. A 2020 meta-analysis confirmed that alcohol worsens snoring and sleep apnoea, raising the number of breathing disturbances per hour and lowering overnight oxygen levels.^[3] Alcohol relaxes the very muscles that hold your airway open and blunts the brain’s arousal responses to obstructed breathing.^[4]

3. Raise the head of your bed. In the same 2024 review, elevating the head of the bed by 30 degrees reduced snoring time from 17.3% to 12.5% of the night, and even a modest 7.5-degree tilt produced roughly a 7% relative reduction.^[2] A wedge pillow or risers under the bed head can achieve this.

Two things to note about these quick wins. They only work on the nights you actually do them, so treat them as habits rather than one-off experiments. And they reduce snoring rather than cure its cause — think of them as immediate relief while the longer-term fixes below take effect.

The big three long-term fixes

Lose weight, if you’re carrying extra

For snorers who are overweight, this is the most powerful lever there is — ENT UK describes weight loss as the most effective treatment for snoring.^[5] Extra tissue around the neck and throat narrows the airway directly, which is why the relationship between weight and snoring shows up so consistently in the research.

The landmark Wisconsin Sleep Cohort study put striking numbers on it. A 10% weight gain predicted roughly a 32% increase in the apnoea-hypopnoea index (AHI — the number of breathing disturbances per hour of sleep) and a six-fold increase in the odds of developing moderate-to-severe sleep-disordered breathing, while a 10% weight loss predicted a 26% decrease in AHI.^[6] More recent trial data show a dose-response effect: the more weight lost, the greater the improvement.^[7] You don’t need to reach an “ideal” weight for your airway to notice the difference — the gradient works in your favour from the first kilos.

An honest caveat: this only applies if you’re carrying extra weight. Slim snorers usually snore for anatomical or nasal reasons and should focus elsewhere — see what causes snoring. Our lifestyle changes guide goes deeper on all three of these fixes.

Drink less, especially before bed

Beyond skipping tonight’s nightcap, reducing overall alcohol intake matters — meta-analysis evidence links consumption with worse snoring and disordered breathing, with more breathing disturbances per hour and lower overnight oxygen levels.^[3] Because the mechanism is muscle relaxation while alcohol is in your system,^[4] evening drinks are the ones most worth cutting; but a lower weekly total helps too, and the NHS includes avoiding excess alcohol in its self-help advice for snorers.^[1]

Stop smoking

A 2023 meta-analysis found smokers have higher AHI scores and worse overnight oxygen levels, with a dose-dependent relationship — the association was clearest at 20 pack-years and above.^[8] Encouragingly, this appears reversible: ex-smokers’ snoring has been observed to fall to never-smoker levels within about four years of quitting.^[9]

Every option compared

Here is the full menu, rated by the strength of the evidence.

Two notes on reading the table. First, “best-evidenced” isn’t the same as “best for you” — a MAD is excellent for tongue-based snoring and useless for a blocked nose, which is why the matching section below matters more than the rankings. Second, within the device categories quality varies: for oral appliances, for example, clinical guidelines recommend custom, dentist-fitted, titratable devices over cheap boil-and-bite versions.^[11]

And a note on that last row: acupressure rings and essential oils have no good clinical evidence behind them, and when researchers formally tested a chin strap on its own, it failed to improve either snoring or sleep apnoea.^[18] Our natural remedies review and mouth taping guide take an honest look at the popular alternatives.

Match the fix to the cause

Snoring is a symptom with several possible causes, and mismatched remedies are why so many people conclude “nothing works”.

If your nose is the problem

Congestion, allergies or a deviated septum force you to breathe through your mouth, which promotes snoring. Start by treating the congestion — intranasal steroid sprays improve sleep disturbance in allergic rhinitis^[14] — and consider nasal strips or dilators, which may help how your snoring sounds even though they don’t treat sleep apnoea.^[13]

If you only snore on your back

You’re likely a positional snorer, and you’re in luck: positional therapy — from the classic tennis-ball trick to modern vibrating trainers — has decent evidence and costs little.

If you’re carrying extra weight

Weight loss is your highest-value move,^[5][6] ideally combined with side-sleeping and less alcohol while you work on it. See lifestyle changes.

If your snoring is loud, nightly, and comes with pauses or gasping

Stop experimenting and get assessed. This pattern suggests obstructive sleep apnoea rather than simple snoring, which carries real health risks and has effective treatments — CPAP above all,^[15] plus oral appliances, and now tirzepatide for people with obesity. In its trials, tirzepatide cut breathing disturbances by roughly 55–63% versus minimal change with placebo, alongside 18–20% weight loss.^[19]

Assessment is more straightforward than most people expect: screening questionnaires, and often a home sleep test rather than a night in a sleep lab. Our when to see a doctor guide walks through the whole pathway, from the Epworth Sleepiness Scale to what a sleep study involves. We also have dedicated guides to snoring in women and snoring in children — a snoring child in particular warrants its own conversation with a GP.

The bottom line

Work from cheap and easy to specialist. Tonight: side-sleeping, no evening alcohol, and a raised bed head. This month: tackle weight, drink and cigarettes if they apply to you, and consider starting mouth exercises — they need around three months of daily practice to judge fairly. If snoring persists, a mandibular advancement device is the best-evidenced purchase you can make. And if anything points to sleep apnoea, skip the gadgets and see a doctor — that’s not a failure of self-help, it’s the correct fix for that particular cause.

However loud things are right now, this is a solvable problem for the vast majority of people. Pick the fixes that match your cause, give them a fair trial, and recruit your bed partner as your progress monitor — our partner’s guide will keep them onside while you work on it.
