Perimenopause Insomnia: Why You're Awake at 3 a.m. and What Actually Helps

When it comes to sleep health, your 40s and 50s present the perfect storm. Many people during this time experience increased mental stress, whether from taking on more responsibility at work or caring for aging parents and kids at the same time. And all this happens at the same time as perimenopause. 

Perimenopause is the period leading up to menopause, the end of having a regular menstrual cycle. It’s marked by fluctuations in hormones, primarily estrogen and progesterone. “As estrogen and progesterone fluctuate and eventually drop, the brain loses important scaffolding it used to maintain sleep health,” explains Susan Zink, MD, a board-certified psychiatrist specializing in reproductive psychiatry and founder of EleMental Integrative Psychiatry, “Layer on the common psychological stress of midlife, and you’ve got a recipe for insomnia.”

Fortunately, there are some effective treatments for when perimenopause and insomnia strike at the same time. So if you find it hard to stay asleep or keep waking up at 3am, this guide can help. Continue reading to learn why sleep troubles are more common in midlife and which  perimenopause insomnia treatments actually work.

What is perimenopause insomnia?

Perimenopause insomnia is when someone has trouble falling or staying asleep due to the hormonal changes in the years leading up to menopause. Perimenopause is a long period of time, lasting four to seven years, on average, and can be as long as 14 years. David Ghozland, MD, FACOG, an OBGYN in LA, says many of his patients report insomnia during the menopausal transition. 

Insomnia can occur during a short, often stressful, period, such as when you’re starting a new job or after the death of a family member. Or, it can be chronic or ongoing. Perimenopause insomnia often falls into the second category, because the contributing factors (hormonal fluctuations) are persistent as well.

The condition looks a little different for everyone. For some, perimenopausal insomnia could mean feeling exhausted all day, then as soon as your head hits the pillow, it’s impossible to sleep. It might mean waking up around 2am, tired but wired. Others in perimenopause may wake up an hour before their alarm, fatigued yet unable to fall back asleep. 

Why does perimenopause cause insomnia?

Perimenopause is marked by a fluctuation in estrogen and progesterone. While these are commonly labeled as “reproductive hormones,” they perform various roles throughout the body, says Dr. Zink. Those duties include providing important scaffolding that makes it easy to fall (and stay) asleep.

Estrogen and sleep regulation

“Estrogen is highly involved in the parts of the brain responsible for temperature regulation,” says Dr. Zink. This is why decreasing estrogen levels during perimenopause brings on hot flashes and night sweats. Additionally, it’s hard to fall or stay asleep when the normal temperature changes that help prepare the body for sleep are disrupted, per a review in Current Opinion in Physiology.

Estrogen also plays a role in the body’s circadian rhythm, which is our sleep-wake cycle that controls how alert or sleepy we feel throughout the day, per a 2022 paper in Seminars in Cell and Developmental Biology. That means that when estrogen levels fluctuate, it may also affect your sleep schedule, independent of night sweats.

Progesterone's sedative effect

Progesterone is the body’s natural calming hormone, says Dr. Zink. Part of its job is to help calm the body down around bedtime. A 2023 review published by the Journal of the Endocrine Society found an association between decreased progesterone and trouble falling or staying asleep. 

Cortisol, hyperarousal, and early-morning waking

Cortisol sometimes gets a bad rep as the “stress hormone,” but we actually need a stable cortisol rhythm to function. It normally rises around the time you wake up, then gradually falls. 

According to Johns Hopkins Medicine, cortisol is also regulated by estrogen. When hormone levels fluctuate during perimenopause, cortisol patterns may also shift. Increased cortisol may mean someone wakes up earlier than intended or their nervous system may struggle to stay asleep. 

Is it perimenopause insomnia or something else?

Insomnia during midlife could be due to multiple factors, not just perimenopause. What’s more, the menopausal transition is also associated with other sleep issues, such as sleep apnea and restless leg syndrome. The table below outlines key differences between four common sleep disorders with overlapping symptoms. 

Some of these conditions may co-occur. For example, if experiencing perimenopause insomnia, anxiety may also play a role, since perimenopause increases the risk of anxiety disorders, per a 2025 article in BMC Women’s Health.

All that to say, only a sleep specialist can diagnose what’s actually to blame for any sleep symptoms.

When sleep apnea may be the missing piece

Insomnia isn’t the only sleep condition that becomes more common during perimenopause. According to a 2022 PLoS One review, there’s an uptick in sleep apnea diagnoses once people reach the menopausal transition. 

“Estrogen and progesterone don’t act just in the brain to maintain sleep. They also support muscle tone, including in the airway,” explains Dr. Zink, “As hormone levels fall, the airway becomes less toned, which is a major reason obstructive sleep apnea rates climb in midlife.”

What’s more, if you have insomnia, you might have sleep apnea too. The National Heart, Lung, and Blood Institute reports that insomnia can be a symptom of sleep apnea in women.

To determine if sleep apnea is at play, Dr. Zink recommends speaking with a healthcare provider about a sleep study. This test assesses various metrics related to how well you sleep. It can be done in a lab, which involves sleeping there overnight. Alternatively, you can get an at-home sleep apnea test through a virtual sleep clinic like Dreem Health. 

Why sleep hygiene advice may not be enough

I love chamomile tea before bed and religiously stick to my 9pm bedtime, but sleep hygiene practices do not fix conditions like chronic insomnia. If you’re experiencing midlife insomnia, sleep apnea, or another sleep condition, consult a sleep medicine specialist, who may recommend visiting a sleep clinic (either in-person or a virtual option like Dreem Health) to figure out what’s going on.

Once the specialist figures out the appropriate diagnosis, they can create a treatment plan. And yes, they may still recommend sleep hygiene tips, like a nighttime meditation or sleeping in a dark, quiet room, but these will be add-ons, not the primary treatment method. 

How is perimenopause insomnia treated?

When Dr. Ghozland talks to a patient struggling to sleep, he emphasizes that this can be normal in perimenopause. But normal, he says, does not mean you have to “put up with it.” There are many effective  perimenopause insomnia treatments. Most fall into one of three camps.

Cognitive behavioral therapy for insomnia (CBT-I)

The first-line treatment for insomnia (no matter the cause) is cognitive behavioral therapy for insomnia (CBT-I). CBT-I is a style of talk therapy focused on challenging thoughts and behaviors around sleep. Per Sleep Medicine Reviews, it’s effective at addressing insomnia and improving overall quality of life. 

When it comes to perimenopause insomnia specifically, a 2024 article in Life found that CBT-I reduced perimenopause insomnia severity and improved overall sleep quality for study participants.  

Menopausal hormone therapy

If someone is experiencing insomnia during perimenopause, menopausal hormone therapy (MHT) may help. Formerly known as hormone replacement therapy or HRT, MHT is an FDA-approved treatment that can help restore estrogen and sometimes progesterone levels. It may help relieve severe perimenopause symptoms, including hormonal insomnia.

A 2025 review in the Journal of Clinical Medicine stated that many people experience an improvement in sleep duration and quality after taking MHT. However, a 2024 review in the same medical journal advised that for insomnia specifically, CBT-I should be considered the first-line treatment, and MHT could be prescribed if CBT-I doesn’t work. 

Non-hormonal prescription options

A healthcare provider may recommend non-hormonal prescription options if CBT-I and MHT are not appropriate or effective. These may include the short-term use of medications for sleep, such as zolpidem or zaleplon. They may also recommend an over-the-counter option, such as melatonin. However, the National Institute on Aging warns that these sleep aids only help in the short-term. They don’t address the underlying causes in the same way that CBT-I and MHT might.

How long does perimenopause insomnia last?

Perimenopause sleep problems, including insomnia, can last as long as the menopausal transition. According to research published in the scholarly journal Women, that could be up to 14 years. Before panicking, note that treatment can shorten how long insomnia lasts — by a lot. 

When the appropriate treatment is in place, insomnia may resolve within a few weeks or months. A  study in the Journal of Clinical Medicine found that some participants' insomnia resolved during their six week course of CBT-I. 

When to see a sleep specialist

If you find it harder to fall or stay asleep night after night, see a sleep specialist. “Perimenopause insomnia is normal, but it doesn’t have to be something they have to endure,” says Dr. Ghozland, “The female body is resilient, but resilience doesn't mean women should be expected to push through months of exhaustion without support.”

Here are some more specific signs when to manage sleep difficulties at home and when to see a specialist. 

Manage at home

• It’s hard to fall asleep occasionally, such as once or twice a year.

• Daytime functioning is not affected.

• You aren’t experiencing other symptoms .

See a sleep specialist

• It’s hard to fall asleep night after night.

• Daytime functioning is affected.

• You experience additional symptoms, like daytime sleepiness or dry mouth upon waking.

If you’re unsure where to find a sleep specialist, there are two easy places to turn. The first is to visit a primary care provider. They can conduct an initial assessment and refer you to the right specialist afterwards. This requires an additional appointment and extra time waiting on the referral, which means more nights spent tossing and turning. 

For a faster route, consider Dreem Health’s virtual sleep clinic. No referral is necessary, and you can attend consultations with a sleep specialist remotely. Plus, Dreem Health works with insurance providers in all 50 states to help cover the cost. Book a consultation to learn more.

The bottom line

Insomnia and other sleep troubles are unfortunately common during perimenopause. If you’re having trouble falling or staying asleep, seek out a sleep specialist, either in-person or through a virtual sleep clinic like Dreem Health. A sleep specialist can order a sleep study to assess what’s going on and use the results to create a personalized treatment plan.

Frequently asked questions (FAQs)

Does insomnia go away after menopause? 

For some people, insomnia may go away after menopause. However, hormonal fluctuations aren’t the only cause of midlife insomnia. The extra life stressors during this time (hello caregiving for your parents and children all at once) and other health conditions may also contribute to insomnia. These could persist after menopause ends and may require a different treatment approach.

How can I get better sleep during perimenopause? 

During perimenopause, it can be hard to get enough quality sleep, even if you follow the classic sleep hygiene tips, like sleeping in a dark room and doing a calming activity right before bed. Many people experiencing perimenopause find their sleep improves with treatment, such as menopausal hormone therapy, a non-hormonal treatment for menopause, and/or cognitive behavioral therapy for insomnia. A healthcare provider can determine the appropriate approach for you.

What is the 15-minute rule for insomnia? 

The 15-minute rule is the concept that if someone is still awake after laying down for fifteen minutes, they should get out of bed. A collection of research in StatPearls has found that participants with insomnia spent less time awake if they followed this rule.
