Sleep research has historically focused on male subjects, and clinical presentations of sleep disorders in women are often different enough from the textbook description that they are frequently missed or misdiagnosed. Women are more likely to have their sleep complaints attributed to stress, anxiety, or depression before a sleep disorder is considered. And yet sleep disorders in women are common, clinically significant, and highly treatable when properly identified.
This article explains how sleep disorders present differently in women, which life stages carry the highest risk, and what to ask for if you suspect a sleep problem has been overlooked. If you are concerned about your sleep, a clinical consultation with a sleep medicine physician is the right starting point.
How Sleep Changes Across a Woman’s Life
Women’s sleep is influenced significantly by hormonal changes across the lifespan. Each major hormonal transition, the menstrual cycle, pregnancy, perimenopause, and menopause, brings characteristic sleep disruptions that range from mildly inconvenient to severely impairing.
These transitions also change the risk profile for sleep disorders. A woman who had no sleep problems in her twenties and thirties may develop significant OSA or insomnia during perimenopause. Understanding this progression helps ensure that symptoms are not dismissed as a normal part of aging.
The Menstrual Cycle
Sleep quality tends to change across the menstrual cycle. Many women report more disturbed sleep and more fatigue in the late luteal phase, the week before menstruation, when progesterone levels drop. This is also when premenstrual symptoms are most prominent. Additionally, restless leg syndrome symptoms worsen during this phase in some women, making it harder to fall and stay asleep.
Pregnancy
Pregnancy affects sleep at every trimester. Early pregnancy brings fatigue and frequent waking. Later stages bring physical discomfort, frequent urination, and significantly elevated risk of obstructive sleep apnea. Pregnancy-related OSA is often missed because the standard clinical picture, overweight older male, does not fit. However, the upper airway changes that accompany pregnancy, including increased neck circumference and mucosal swelling, create real OSA risk regardless of a woman’s baseline weight or age.
Snoring during pregnancy is common and should not be dismissed. If a pregnant patient is snoring, excessively fatigued, or observed to have pauses in breathing, a sleep assessment is appropriate. Untreated OSA during pregnancy is associated with adverse outcomes including gestational hypertension and preeclampsia.
Perimenopause and Menopause
The perimenopausal transition is one of the highest-risk periods for sleep disruption in women. Hot flushes and night sweats fragment sleep directly. Declining estrogen and progesterone alter sleep architecture. Mood changes and anxiety, which are common in perimenopause, further compound insomnia.
Sleep apnea risk also rises significantly after menopause. Before menopause, women are substantially less likely than men to have OSA. After menopause, that gap narrows considerably. Yet postmenopausal women with OSA are still less likely to present with the classic complaint of snoring and gasping. They more commonly report fatigue, insomnia, and mood disturbance, symptoms that are routinely attributed to the menopause itself rather than to a breathing disorder that is disrupting sleep.
If you are perimenopausal or postmenopausal and have unexplained fatigue or insomnia that has not responded to standard treatment, a diagnostic sleep test is worth discussing with your physician.
Why Women Are Underdiagnosed
The textbook presentation of obstructive sleep apnea, loud snoring, witnessed apneas, excessive daytime sleepiness in an overweight middle-aged man, does not describe how OSA typically presents in women. Women with sleep apnea more commonly report:
- Insomnia or difficulty maintaining sleep
- Fatigue and low energy rather than overt sleepiness
- Mood changes, depression, or anxiety
- Morning headaches
- Frequent nighttime awakening
These symptoms are more readily attributed to stress, mental health conditions, or hormonal changes than to a breathing disorder. As a result, women are more likely to receive a mental health diagnosis before a sleep disorder is considered. Many receive treatment that partially helps but does not fully resolve symptoms, because the underlying sleep disorder remains unaddressed.
If your sleep symptoms have persisted despite mental health treatment, or if insomnia has been difficult to resolve, ask directly whether a sleep disorder assessment would be appropriate. A sleep medicine physician will take your symptoms seriously regardless of whether they fit the male-typical presentation.
Getting the Right Assessment
A sleep medicine physician who understands how sleep disorders present in women will take a full history that includes hormonal history, reproductive health, and life stage. They will not require that you match a specific symptom profile to proceed with investigation.
To get a referral to a sleep medicine physician, speak with your family doctor, nurse practitioner, or gynecologist. In Ontario and British Columbia, the referral must come from a physician or nurse practitioner. A referral from another specialist, such as an endocrinologist, cardiologist, or psychiatrist, is also appropriate in most provinces.
Diagnostic sleep testing is the same for women as for men, either a home sleep test or an in-lab polysomnography depending on clinical presentation. A trained sleep technologist conducts in-lab studies and ensures data quality throughout the night. The data is then interpreted by a sleep medicine physician who will explain what the results mean and what treatment options are available.
MedSleep has community sleep clinic locations across Alberta, British Columbia, New Brunswick, Nova Scotia, and Ontario. If you are unsure where to start, contact a location near you to find out what is available in your area.
What Treatment Looks Like
Treatment depends on the specific disorder identified. For sleep apnea, options include CPAP therapy, an oral appliance, or positional therapy depending on severity and clinical profile. For insomnia, cognitive behavioural therapy for insomnia (CBT-I) is the evidence-based first-line treatment. For restless leg syndrome, treatment may involve addressing underlying deficiencies, lifestyle changes, or medication.

Frequently Asked Questions
Can hormone therapy help with sleep during menopause?
Menopausal hormone therapy (MHT) reduces hot flushes and night sweats, which are a direct cause of sleep fragmentation. For some women, MHT meaningfully improves sleep quality. It does not, however, treat an underlying sleep disorder. If OSA or another sleep disorder is also contributing to poor sleep, it needs to be assessed and addressed separately. A clinical consultation can help clarify whether a sleep disorder is present alongside menopausal symptoms.
I don’t snore. Can I still have sleep apnea?
Yes. Many women with OSA do not present with prominent snoring. The absence of snoring does not rule out a breathing disorder. If you have persistent fatigue, unrefreshing sleep, or unexplained mood and cognitive symptoms, a sleep assessment is warranted regardless of whether snoring is present.
Is insomnia more common in women?
Yes. Women are approximately twice as likely as men to experience insomnia. The reasons are multifactorial, hormonal, psychological, and social factors all contribute. Importantly, insomnia in women is also more likely to be undertreated. CBT-I is effective regardless of gender and should be discussed with your sleep medicine physician or family doctor.
My doctor says my poor sleep is just menopause. What should I do?
Menopause does affect sleep, but it does not explain all sleep problems in perimenopausal or postmenopausal women. If your sleep has not improved with standard menopausal management, or if your daytime fatigue is out of proportion to what you would expect, ask for a referral to a sleep medicine physician for a formal assessment.
At what age should women start thinking about sleep disorder risk?
There is no single age threshold. However, the transitions that carry the highest risk, pregnancy and perimenopause, typically occur between the late twenties and early fifties. Sleep problems that emerge or worsen during these periods are worth investigating rather than attributing entirely to hormonal changes. A sleep assessment at any age is appropriate when symptoms are persistent and affecting daily function.
