Snoring is the sound of your airway partially collapsing while you sleep. Understanding why you snore is the first step to fixing it — because the cause determines the cure.
The Basic Mechanism
When you fall asleep, throat muscles relax. In snorers, they relax enough to narrow the airway, and incoming air vibrates the surrounding tissue.
The Real Causes
- Sleep position. Back-sleeping lets the tongue fall backward into the airway — the single most common, most fixable cause.
- Weight. Extra tissue around the neck crowds the airway.
- Alcohol and sedatives. Over-relax throat muscles.
- Nasal congestion. Forces mouth-breathing and drops airway pressure.
- Anatomy. A long soft palate, large tonsils, or a small jaw all narrow the space.
- Age. Throat muscles lose tone over time.
The Red Flag: When Snoring Isn’t Just Snoring
If your snoring comes with gasping, choking, pauses in breathing, or daytime exhaustion, that can be obstructive sleep apnea — a medical condition. See a doctor, don’t self-treat with a mouthpiece.
The Bottom Line
You snore because something narrows your airway while you sleep — usually position, weight, alcohol, congestion, or anatomy. Identify your main cause and the fix gets obvious.
