Why Do I Snore? How Your Bed and Sleep Position Help

Snoring happens when airflow through the nose and throat is partially blocked during sleep. The tissues in the airway vibrate as you breathe, creating the sound that can range from a soft rumble to a wall-shaking rattle. It's common, but it's not always harmless, and the right sleep setup can sometimes reduce it.

Common causes

• Relaxed throat muscles, especially with age or after alcohol use.
• Nasal congestion from allergies or a cold.
• Sleeping on your back, which lets the tongue and soft palate collapse backward.
• Excess weight, which adds tissue around the airway.
• A naturally narrow airway or enlarged tonsils.

How sleep position changes snoring

Back sleeping is the worst position for snoring because gravity pulls the tongue and soft tissues toward the back of the throat. Side sleeping is usually better because it keeps the airway more open. If you can't stay on your side, a body pillow or a positional trainer can help.

Can a mattress help?

A mattress that supports side sleeping can indirectly reduce snoring by making it easier to stay off your back. A medium to medium-firm mattress with enough pressure relief at the shoulders and hips makes side sleeping comfortable all night. An adjustable base that elevates the head can also help by using gravity to keep the airway open.

When snoring is more than a nuisance

Loud, chronic snoring with pauses in breathing, gasping, or daytime sleepiness can be a sign of obstructive sleep apnea. Sleep apnea is a serious medical condition linked to high blood pressure, heart disease, and stroke. If you or your partner notice these signs, talk to a doctor and ask about a sleep study.

Practical steps to try first

1. Sleep on your side.
2. Avoid alcohol within 3 hours of bedtime.
3. Treat nasal congestion with saline rinses or allergy medication.
4. Elevate the head of the bed by 4 to 6 inches.
5. Maintain a healthy weight if excess tissue is a factor.
