Snoring vs. sleep apnea: how to tell the difference
4 min read · Reviewed 2026-10-06
Short answer
Snoring is the sound of vibrating tissue in a narrowed airway; sleep apnea is when that airway repeatedly closes so breathing pauses. Snoring that is loud, happens most nights, and comes with gasping, observed breathing pauses or daytime sleepiness is a reason to get screened.
Why people snore
During sleep, the muscles of the throat relax. If the airway narrows, air moving through it makes the tissues vibrate — that's snoring. Alcohol, nasal congestion, sleeping on your back and excess weight can all make it worse.
Signs snoring may be sleep apnea
- Snoring is loud and happens most nights
- Snoring stops, then ends in a snort or gasp
- A bed partner notices pauses in breathing
- You feel sleepy or unrefreshed during the day
- You have high blood pressure
What to do next
A free screening takes a few minutes and shows whether your answers point to low, intermediate or high risk. If your risk is elevated, a sleep study is the way to know for sure.
