A blocked nose and allergies

When the nose is the problem: rinses, sprays, strips and a bedroom that's kinder to allergies.

Why a blocked nose leads to snoring

When the nose is blocked, you need to breathe in harder, which pulls the soft walls of the throat inwards, and you are more likely to breathe through your mouth, which lets the jaw and tongue fall back. Both make the airway narrower and more likely to vibrate. In a study of almost 5,000 adults, people with frequent night-time nasal symptoms were more likely to snore habitually 1.

What helps

Key study

Nasal steroids, congestion and sleep

  • 20 adults
  • Allergic rhinitis
  • Placebo-controlled

People with allergic rhinitis used a nasal corticosteroid spray or a placebo, and kept a daily diary of their nose, sleep and daytime sleepiness. Congestion and sleep improved significantly with the steroid spray but not with the placebo; daytime sleepiness improved too, but not significantly.

An allergy-friendlier bedroom

  • Wash bedding weekly in hot water, and use dust-mite covers on pillows and mattress.
  • Keep pets out of the bedroom.
  • Shower before bed in pollen season, and keep windows closed on high-pollen nights.
  • Keep the bedroom dust-free, and consider a humidifier if the air is very dry.
Can allergies cause snoring?

Yes. Allergy-related nasal congestion is linked with habitual snoring and with sleep-disordered breathing 1.

Why do I snore more with a cold?

A cold blocks the nose, so you breathe harder and through your mouth. The snoring usually settles when the cold does.

Do nasal sprays help snoring?

Steroid sprays can help when allergies are the cause 2. Saline is safe every day. Decongestant sprays only for a few days.

Does a humidifier help snoring?

It may ease a dry, irritated nose and throat, which some people find helps. There is little research on snoring itself.
