Why Do People Snore? Causes, Solutions & What Actually Helps

Snoring is one of the most common sleep complaints in the world. In fact, millions of adults snore regularly — and many don’t even realise how disruptive it can be until a partner tells them.

So why do people snore? What actually causes it? And more importantly — what can you realistically do about it?

Let’s break it down in simple terms.

Why Do People Snore?

Snoring happens when air can’t move freely through your nose and throat during sleep. When airflow is partially blocked, the surrounding tissues vibrate — and that vibration creates the sound we call snoring.

The more restricted the airway, the louder the snore.

Snoring can be occasional (after a late night or a cold) or chronic (most nights). The key is understanding why it’s happening.

Common Causes

There isn’t just one cause. Snoring usually happens because of a combination of factors:

1 Relaxed Throat Muscles

When you fall asleep, the muscles in your tongue, soft palate and throat relax. Sometimes they relax too much and partially block the airway.

Common trigger: Alcohol before bed. Sleep hygiene improvements like avoiding alcohol near bedtime (supported by Mayo Clinic)

2 Sleeping on Your Back

When you lie on your back, gravity pulls the tongue backward, narrowing the airway.  Side-sleeping vs back-sleeping benefits. (Healthline)

This is one of the most common causes of snoring.

3 Nasal Congestion or Blocked Nose

Allergies, sinus infections, a deviated septum or a cold can restrict airflow through the nose, forcing you to breathe through your mouth — increasing snoring.

4 Being Overweight

Extra tissue around the neck can narrow the airway and increase vibration.

5 Mouth & Jaw Structure

Some people naturally have:

• A smaller jaw
• Enlarged tonsils
• A long soft palate

These structural factors can increase snoring.

6 Sleep Apnea

Loud, chronic snoring combined with gasping or pauses in breathing may be obstructive sleep apnea (OSA) — a medical condition that requires professional evaluation.

If someone feels exhausted during the day despite “sleeping,” it’s worth checking.

Snoring Solutions

Now the part everyone really wants — what works?

There’s no single magic fix. The best solution depends on the cause.

Let’s look at the most common options, plus their pros and cons.

1 Sleeping on Your Side

Changing sleep position can reduce snoring caused by back-sleeping.

✅ Pros:

• Free
• Immediate effect for positional snorers
• No devices required

❌ Cons:

• Hard to maintain all night
• Doesn’t help structural snoring

2 Weight Loss

Even moderate weight loss can reduce neck tissue pressure on the airway. Certain lifestyle factors can also contribute to snoring. For example, diet and late-night eating habits may worsen airway relaxation. You can read more about this in our guide on [foods to avoid before sleep to reduce snoring]

✅ Pros:

• Improves overall health
• Can significantly reduce snoring
• Long-term benefit

❌ Cons:

• Takes time
• Not effective for thin snorers
• Requires lifestyle change

3 Nasal Strips or Nasal Sprays

Helps open nasal passages.

✅ Pros:

• Easy to use
• Good for congestion-related snoring
• Affordable

❌ Cons:

• Won’t fix throat-based snoring
• Temporary solution
• Doesn’t help jaw-related airway collapse

4 Do Mouthpieces Work?

These are one of the most effective non-surgical solutions for many people. For people whose snoring is caused by jaw relaxation or airway obstruction, anti-snoring mouthpieces are often one of the most effective non-invasive solutions.

They work by gently holding the lower jaw slightly forward, which keeps the airway open and reduces vibration.

There are two main types:

🔹 Boil and Bite Mouthpieces

These are softened in hot water and then moulded to your teeth for a semi-custom fit. Products like SnoreMeds are designed to gently move the lower jaw forward during sleep to help keep the airway open.

✅ Pros:

• More affordable
• Custom fit at home
• Good balance between comfort and effectiveness
• Widely available

❌ Cons:

• Fit depends on proper moulding
• Less precise than dentist-made versions
• Can feel bulky initially

🔹 Adjustable Mouthpieces

These allow you to gradually move the lower jaw forward using a screw or adjustment system. Products like SnoreRX are designed to gently move the lower jaw forward during sleep to help keep the airway open.

✅ Pros:

• Customisable jaw advancement
• More precise adjustment
• Can improve comfort over time
• Often better for moderate snoring

❌ Cons:

• More expensive than boil & bite
• May require gradual adjustment period
• Slightly more complex to use

Which One Is Better?

It depends.

• Mild to moderate snorers often do well with boil and bite.
• Those who need more control over jaw positioning may prefer adjustable models.

Both have their place — and both can be effective when fitted correctly.

5 Sleep Apnea and CPAP

CPAP delivers continuous air pressure to keep the airway open.

✅ Pros:

• Gold standard for sleep apnea
• Highly effective
• Medically proven

❌ Cons:

• Requires prescription
• Expensive
• Some people struggle with comfort

6 Surgery

In some cases, excess tissue can be surgically reduced.

✅ Pros:

• Permanent structural change
• May reduce severe snoring

❌ Cons:

• Expensive
• Invasive
• Not guaranteed to work
• Recovery time required

What Actually Works Best?

For most people:

✔ Lifestyle changes help
✔ Position changes help
✔ Treating nasal congestion helps
✔ Mouthpieces are often the most practical long-term solution

The “best” solution depends entirely on the cause of your snoring. Snoring in women can sometimes have different contributing factors, which we explore further in our article on [why women snore and how to stop it]

If it’s jaw or tongue related — mouthpieces like SnoreMeds are usually very effective.
If it’s congestion — treat the nose.
If it’s weight-related — address lifestyle.
If it’s sleep apnea — seek medical advice.

Final Thoughts

Snoring isn’t just noise — it’s airflow restriction.

The good news? There are multiple solutions, and most people can significantly reduce or stop snoring without surgery.

The key is matching the solution to the cause.

And sometimes, a combination approach works best.

Please Note: If you experience loud, chronic snoring with pauses in breathing or daytime sleepiness, a medical evaluation is recommended, as these can be signs of sleep‑related breathing disorders.
