Why do people snore during sleep?

During sleep, the muscles of the throat and tongue relax. If the airway becomes narrow, air flowing through it makes the soft tissues vibrate, and that vibration is the sound of snoring.

Common causes

  • Excess weight, especially around the neck.
  • Sleeping on the back, which lets the tongue fall backwards.
  • Alcohol, sleeping pills and sedatives that relax the throat muscles.
  • Nasal blockage from allergy, a cold or a deviated septum.
  • Large tonsils or adenoids, particularly in children.
  • Smoking, which irritates and swells the airway lining.

Simple steps that can help

  • Sleep on your side.
  • Lose excess weight.
  • Avoid alcohol and sedatives in the hours before bed.
  • Treat nasal congestion and allergies.
  • Stop smoking.

When snoring is more than a noise

Snoring with pauses in breathing, gasping, daytime sleepiness or high blood pressure may indicate obstructive sleep apnea. In that case, a sleep study is advised.

Frequently asked questions

Is snoring always a sign of sleep apnea?

No. Many people snore without sleep apnea. But loud snoring with breathing pauses or daytime sleepiness should be checked.

Should children who snore see a doctor?

Yes, if snoring is regular. In children it is often due to enlarged tonsils or adenoids and can affect sleep, behaviour and growth.
