Snoring is one of those problems that sounds trivial until you are the one lying awake next to it — or the one waking yourself up with the noise. It is also more common than most people admit, and it usually has a mechanical cause that can be improved without surgery.
This guide covers why snoring happens, the fastest practical fixes, and when it is time to see a doctor. If you want better sleep for you and whoever shares the room, start here.
Why you snore
Snoring happens when airflow through your mouth or nose is partially blocked during sleep. The tissues in the airway vibrate as you breathe, producing the sound. Common causes include:
- Nasal congestion. A blocked nose forces you to breathe through your mouth, which increases vibration.
- Sleeping on your back. Gravity pulls the tongue and soft palate backward, narrowing the airway.
- Excess weight. Extra tissue around the neck can press on the airway.
- Alcohol or sedatives before bed. These relax the throat muscles too much.
- Aging. Muscle tone in the airway decreases over time.
Not all snoring is harmless. Loud, chronic snoring can be a sign of obstructive sleep apnoea, a condition where breathing repeatedly stops and starts during the night. If you wake up gasping, have morning headaches, or feel exhausted despite a full night in bed, see a clinician.
First-line fixes that work for most people
1. Sleep on your side
Back sleeping is the most common positional trigger. Use a body pillow or wedge pillow to make side sleeping comfortable. If you keep rolling onto your back, try sewing a tennis ball into the back of an old T-shirt — it is low-tech but effective.
2. Open your nose before bed
A saline rinse, nasal strips, or a short steam shower can reduce congestion and help nasal breathing. If allergies are the cause, treating the allergy usually fixes the snoring.
3. Skip alcohol within three hours of bed
Alcohol relaxes the throat and makes airway collapse more likely. The effect is strongest in the first few hours of sleep.
4. Elevate your head
Raising the head of the bed by 10–15 centimetres, or using a wedge pillow, can reduce airway collapse by using gravity to your advantage.
5. Maintain a healthy weight
Even a modest reduction in neck circumference can reduce snoring for people whose weight contributes to airway narrowing.
When to get checked
See a doctor or sleep clinic if snoring is:
- Loud enough to be heard through a closed door
- Paired with pauses in breathing, gasping, or choking
- Causing daytime sleepiness, high blood pressure, or morning headaches
These can be signs of sleep apnoea, which needs proper diagnosis and treatment.
Putting it together
Start with side sleeping, nasal opening, and no alcohol at night. Most simple snoring improves within a week or two.
