Why Snoring Gets Worse in Winter (and How Side-Sleeping Can Help)

If your snoring seems louder in the winter — or your partner insists it is — you’re not imagining it.

Cold air, dry indoor heating, congestion, late-night holiday meals, and alcohol can all irritate your airway and make winter one of the worst seasons for snoring. The good news? A few small adjustments — especially learning to stay comfortably on your side — can make a real difference.

In this guide, we’ll explore:

• Why winter is such a “perfect storm” for snoring
• Why sleep position matters so much
• Practical winter tips to reduce snoring
• A 30-second quiz to find your ideal side-sleeping setup

Why Snoring Often Gets Worse in Winter

1. Cold, dry air and indoor heating

Cold outdoor air and dry furnace heat irritate the nose and throat. When airway tissues become dry or inflamed, they vibrate more easily — which produces louder snoring. You may also notice more mouth breathing, dry mouth, or morning sore throat.

2. Colds, flu and winter allergies

Congestion forces more breathing through the mouth, which increases snoring dramatically. Even mild nasal blockage can turn light snoring into heavy snoring during the winter months.

3. Holiday meals, weight changes and alcohol

Large evening meals, holiday treats, and seasonal drinks all influence snoring. Extra weight around the neck can narrow the airway, and alcohol relaxes throat muscles — both of which worsen snoring, especially when lying on your back.

4. Back-sleeping becomes the default

When you’re tired, congested, or full, it’s easy to roll onto your back. Unfortunately, back-sleeping is the worst position for snoring because gravity pulls the tongue and soft tissues backward, narrowing the airway.

Why Side-Sleeping Is So Helpful for Snoring & Positional Sleep Apnea

Sleep specialists often recommend side-sleeping for snoring and positional sleep apnea — a type of sleep apnea that becomes much worse on the back. When you sleep on your side:

• The tongue is less likely to fall back and block the airway
• The throat stays more open and stable
• Vibration of throat tissues is reduced
• Many people snore less and wake feeling more rested

The challenge? Most people roll onto their backs during the night. That’s why positional therapy tools exist — to gently keep you on your side without discomfort.

Your Winter Snoring Checklist

1. Improve bedroom air quality

• Use a humidifier if your home is dry
• Keep the bedroom slightly cooler
• Air out the room briefly for fresh airflow

2. Reduce nasal congestion

• Try saline sprays, warm showers, or nasal strips
• Follow medical guidance for decongestants
• Support nasal breathing as much as possible

3. Adjust meal and alcohol timing

• Avoid heavy meals 2–3 hours before bed
• Limit alcohol in the 3 hours before bedtime
• Give your airway more time to stay open and relaxed

4. Make side-sleeping your default

Try body pillows, placing a pillow behind your back, or using purpose-built positional therapy tools that comfortably prevent rolling onto your back.
