Snoring in Women — Common, Under-Reported, Nothing to Hide

If you’re a woman who snores, the first thing to know is that you are in very large company. Roughly a tenth to a quarter of women snore habitually, and about half of all adults snore at least occasionally.^[1][2] The second thing to know is that women’s snoring is systematically under-reported, under-discussed and under-diagnosed — and that has real consequences for women’s health.

Snoring has long carried a lazy cultural image: it is something middle-aged men do. The research tells a different story. Women snore almost as often, and almost as loudly, as men — they are simply far less likely to say so. This article looks at what the evidence actually shows about snoring in women, why hormones, menopause and pregnancy matter, and what to do about it.

Women snore almost as much as men — they just don’t say so

A 2019 study in the Journal of Clinical Sleep Medicine recorded 1,913 patients referred to a sleep clinic and compared what their microphones picked up with what patients said about themselves. The gap was striking: 88% of the women objectively snored, but only 72% reported being snorers. Men, if anything, slightly over-reported — 93.1% said they snored, while 92.6% actually did.^[3][4]

Nor was women’s snoring daintier. Women’s mean maximum snoring intensity was 50 decibels against men’s 51.7 — a difference of less than two decibels. Judged against the study’s severity bands (mild snoring at 40–45 dB, very severe at 60 dB and above), 49% of the women had severe or very severe snoring.^[3]

The researchers’ conclusion was blunt: women under-report snoring, probably because of social stigma. That matters, because “do you snore?” is one of the first questions a doctor asks when screening for sleep apnoea. If women answer no when the true answer is yes, the whole diagnostic pathway can stall at the first step.

Why women’s sleep apnoea gets missed

Snoring is the most common symptom of obstructive sleep apnoea, a condition in which the airway repeatedly narrows or closes during sleep. A major review by Franklin and Lindberg found sleep apnoea (defined as five or more breathing events per hour) in roughly 22% of men and 17% of women — a much smaller gender gap than the stereotype suggests. One population study found OSA in up to 50% of women aged 20–70.^[5]

Yet women are diagnosed far less often than men. Part of the reason is the reporting gap above. Another part is that women with sleep apnoea frequently present differently: instead of the textbook picture of loud snoring and witnessed pauses in breathing, women more often describe fatigue, insomnia and low mood.^[5] Those symptoms are easily attributed to stress, depression or “just life” — and the sleep disorder underneath goes unexamined.

The practical lesson: if you are persistently exhausted, sleeping badly or struggling with your mood, and you snore (or a partner says you do), sleep-disordered breathing belongs on the list of explanations to rule out. Our guide to when to see a doctor about snoring explains how assessment works.

Hormones: why oestrogen and progesterone seem to protect

Why do women snore less than men before mid-life, and more afterwards? A large part of the answer appears to be hormonal.

A 2022 analysis of 774 women aged 40–67 from the European Community Respiratory Health Survey measured sex hormones in blood and matched them against snoring. The findings pointed the same way at every turn: a doubling of estrone (an oestrogen) was associated with 19% lower odds of snoring, and a doubling of progesterone with 9% lower odds. Among women who did snore, higher oestrogen levels were associated with 17–23% lower odds of irregular breathing during sleep.^[6]

In other words, female sex hormones seem to help keep the upper airway stable during sleep. When they decline, the airway becomes more collapsible — which brings us to menopause.

Menopause and snoring

Two landmark studies show what happens when hormone levels fall.

Bixler and colleagues, in a large population study published in 2001, found sleep apnoea in 3.9% of men and 1.2% of women overall — but the female figure concealed a dramatic split. Among premenopausal women, prevalence was just 0.6%. Among postmenopausal women not using hormone replacement therapy (HRT), it was 2.7% — more than four times higher. Postmenopausal women who did use HRT looked like premenopausal women, at 0.5%.^[7]

The Wisconsin Sleep Cohort reached a similar conclusion in 2003: peri- and postmenopausal women were more likely to have elevated levels of sleep-disordered breathing, and the effect held independently of age and body habitus — that is, it wasn’t simply ageing or mid-life weight change doing the work.^[8]

None of this means HRT should be taken to treat snoring — that is a decision to make with your doctor for broader reasons. But it does mean that new or worsening snoring around menopause is a recognised physiological change, not a personal failing, and it is worth taking seriously rather than hiding.

Snoring in pregnancy

Pregnancy is the other time in life when snoring commonly appears out of nowhere. Hormonal changes and nasal congestion play a role,^[10] and snoring is particularly common in the final month.^[2]

In a University of Michigan study of more than 1,700 pregnant women, about a quarter began snoring frequently during pregnancy. That would matter little if it were purely cosmetic — but it isn’t. Pregnancy-onset snoring was associated with roughly double the risk of gestational hypertension (new high blood pressure in pregnancy), and the researchers estimated that up to 19% of hypertensive disorders of pregnancy might be attributable to sleep-disordered breathing.^[9][11]

The encouraging news is that pregnancy-onset snoring usually reflects temporary changes. But because of the blood-pressure link, it is one of the clearest cases where “just snoring” deserves a mention to a professional.

What women who snore should do

Everything in our complete guide to stopping snoring applies to women just as much as men. A few points deserve emphasis:

• Say it out loud. Tell your GP you snore, if you do. Given how much hangs on that one question, accuracy beats modesty. If you sleep alone and aren’t sure, a recording app can tell you (see our FAQ).
• Don’t let atypical symptoms fool you. Fatigue, insomnia and low mood are common presentations of sleep apnoea in women.^[5] If they persist, ask about sleep-disordered breathing — our guide to seeing a doctor covers the screening questionnaires and sleep studies involved.
• Address the general risk factors. Alcohol near bedtime, back-sleeping, nasal congestion and weight all affect snoring in women exactly as in men.^[12][13] See what causes snoring and lifestyle changes that help.
• In pregnancy, tell your midwife. As above — a one-sentence disclosure is all it takes.

Nothing to be embarrassed about

Perhaps 88 in every 100 women referred to a sleep clinic snore.^[3] Snoring is a mechanical fact about airflow and soft tissue, influenced by anatomy, hormones and life stage — not a comment on femininity, attractiveness or self-discipline. The women best served by that fact are the ones who treat snoring the way they would treat any other symptom: worth mentioning, worth investigating, and very often fixable.
