Your partner has started nudging you at 2am. Or you've woken yourself up with a snort loud enough to be embarrassing.
If you've never made a sound in your sleep before and now you're rattling the windows at 30 weeks, that's a real and common change. Most of the time it's nothing more than swollen airways and extra fluid. Sometimes it's a useful signal, and that's the part worth knowing about.
We'll be upfront: this isn't a symptom to solve with gadgets off the internet. It's one to mention at your next appointment. Here's what to say and why it matters.
Why it starts
We're not clinicians, so here's the general picture rather than us explaining your airway as though we're the authority on it.
Your nose is congested even without a cold. Pregnancy hormones increase blood flow to the tissues lining your nose and throat, and those tissues swell. A blocked nose means mouth breathing, and mouth breathing means snoring.
There's more fluid to redistribute. Blood volume rises substantially in pregnancy. Lie down and some of that fluid settles into the soft tissue around your neck, which leaves a little less room for air.
Everything's more relaxed. Progesterone relaxes smooth muscle throughout the body, including the soft palate and throat, so the airway is more inclined to narrow when you're asleep.
Put those together and a woman who has never snored in her life can start doing it in the third trimester.
Normal, versus worth raising
Most pregnancy snoring is unremarkable:
-
Mild and rhythmic, mostly when you're congested or particularly tired
-
Started gradually in the late second or third trimester
-
Settles when you change position
-
You wake up reasonably rested
These ones are worth mentioning, and not because of the noise:
-
Loud snoring most nights of the week
-
Choking, gasping or snorting that wakes you or your partner
-
Your partner noticing you stop breathing for a moment
-
Heavy daytime exhaustion, or nodding off when you don't mean to
-
Waking with a dry mouth, sore throat, or a headache most mornings
Better Health Channel has information on obstructive sleep apnoea, where the upper airway narrows or closes repeatedly through the night. It's diagnosed with a sleep study, not by reading a blog, which is exactly why this belongs in a conversation with your GP or midwife.
Why your midwife actually cares
This is the part most articles skip, and it's the reason we've written this one.
Habitual snoring that starts during pregnancy has been linked in research to higher blood pressure and to pre-eclampsia. We're not going to overstate the strength of that link, and it's an association rather than a certainty, but it's real enough that clinicians take new snoring seriously as a prompt to check your blood pressure properly.
That's a good thing. It means mentioning your snoring is a low-effort way of getting something useful checked. Nobody is going to think you're wasting their time.
What to say at your appointment
You don't need to make a thing of it. Three details are enough:
-
When it started and whether it's most nights or occasional
-
What your partner has noticed, particularly any gasping, choking or pauses
-
How you feel when you wake up, rested or wrecked
From there your midwife or GP can check your blood pressure, look at the rest of the picture, and refer you for a sleep study if it's warranted. Sleep studies in pregnancy are straightforward and non-invasive.
If you'd rather understand the territory before you go, Monique at The Middee Society is a practising Australian clinical midwife specialist who runs childbirth education classes and covers this kind of question regularly.
Things that help in the meantime
None of these treat sleep apnoea. They make mild congestion-driven snoring a bit better.
Sleep on your side. Lying on your back lets the tongue and soft palate fall back against the airway. Side-lying keeps it more open, and from 28 weeks it's the recommended position anyway. If you keep rolling flat, something behind your back helps: our Pregnancy Pillow has a back wedge for exactly that, and the front and back pieces can be positioned to prop your upper body slightly at the same time.
Lift your head and chest a little. Ten to fifteen centimetres of elevation through the torso, not just the neck. Stacking pillows under your head alone tends to kink your neck and make things worse.
Rinse your nose before bed. A plain saline spray or rinse clears mucus without medication. Non-medicated nasal strips are worth a try too.
Skip the medicated decongestant sprays unless your doctor has said otherwise.
For the wider picture on getting comfortable at night, we've written about pregnancy insomnia and setting up your bedroom.
The short version
New snoring in pregnancy is common and usually down to swollen airways and extra fluid. Sleep on your side, prop your chest a little, rinse your nose. And mention it at your next appointment, particularly if it's loud, most nights, or your partner has seen you stop breathing.
Frequently Asked Questions
Will it stop after the birth?
For most women who only started snoring during pregnancy, it settles in the weeks after birth as hormones and fluid levels return to normal. If it doesn't, that's worth following up.
Can snoring harm my baby?
Light, occasional snoring isn't a concern. Untreated sleep apnoea is a different thing, because repeated dips in oxygen can affect how well the placenta is supplied. That's the reason for getting frequent or loud snoring looked at rather than living with it.
Are anti-snoring sprays safe in pregnancy?
Avoid medicated decongestant sprays unless your doctor has specifically okayed them, since prolonged use can cause rebound congestion. Plain saline sprays and non-medicated nasal strips are the safer options.
My partner says I stop breathing. Is that urgent?
It's not an emergency, but don't let it wait until your next routine appointment if that's weeks away. Ring your midwife or book with your GP and tell them what your partner has observed. That specific detail is the one clinicians most want to hear.
