If you’ve noticed your partner’s snoring getting louder or more frequent during the colder months, you’re not imagining it. Snoring often worsens in winter due to a combination of dry indoor air, temperature changes, and seasonal illnesses. Understanding why this happens can help you reduce those nightly disruptions and improve sleep quality for both of you.

Dry Air and Central Heating

When the temperature drops, heating systems come on—and while they keep homes cosy, they also dry out the air. This lack of moisture irritates the tissues in the nose and throat, leading to inflammation and vibration that make snoring more likely. Adding a humidifier or keeping a glass of water by the bed can help keep airways hydrated.

Winter Colds and Sinus Congestion

Colds, flu, and sinus infections are more common in winter and can all block the nasal passages. When airflow through the nose is restricted, the body compensates by breathing through the mouth, which increases the chance of snoring. Steam inhalation or saline sprays may help, but persistent congestion could indicate a sinus or nasal issue that needs medical assessment.

Allergies and Indoor Air Quality

Many people spend more time indoors during winter, where dust mites, pet dander, and mould spores can build up. These irritants can trigger nasal inflammation and worsen snoring, particularly in older or poorly ventilated properties. Regular cleaning and air filtration can make a noticeable difference.

Lifestyle and Sleep Habits

Alcohol consumption and weight gain over the festive period can also contribute to snoring. Alcohol relaxes the throat muscles, while extra weight can narrow the airway. Reducing alcohol before bedtime and maintaining a balanced diet are simple but effective steps.
For those exploring short-term relief, anti-snoring devices can help some people minimise noise or open airways. Independent reviews of the latest options can be found on Which? Best Anti-Snoring Devices.

When to Seek Professional Help

If snoring is persistent, disrupts sleep, or is accompanied by choking, gasping, or fatigue, it could be a sign of sleep apnoea or an underlying airway obstruction. At London ENT, our specialists can assess your symptoms, perform nasal and throat examinations, and recommend treatments ranging from lifestyle advice to minimally invasive procedures.

For ongoing snoring or throat discomfort, book a consultation with an experienced throat specialist in London. A proper diagnosis is the first step toward quieter, more restful nights.
