Part of our guide: Perimenopause sleep problems and night sweats

You're exhausted by the evening. You get into bed, switch off the light, and your mind switches on. An hour later you're still awake, doing the math on how much sleep you'll get. If this happens night after night, you may be dealing with perimenopause insomnia.

This article covers why falling asleep can get harder in perimenopause, when trouble sleeping counts as chronic insomnia, the treatment US guidelines recommend first, everyday sleep habits, and what to know before trying sleeping pills. If your main problem is waking in the early hours rather than getting to sleep, see our guide to waking at 3am in perimenopause.

The short answer: falling progesterone, night sweats and a busier, more anxious mind can all make it harder to fall asleep in perimenopause. When trouble sleeping happens at least three nights a week for more than three months, it's called chronic insomnia. The American College of Physicians recommends cognitive behavioral therapy for insomnia (CBT-I) as the first treatment, before sleeping pills, and the American Academy of Sleep Medicine strongly recommends it too.

Why perimenopause insomnia happens

Sleep problems are common in the menopause years. In a 2024 survey by the American Academy of Sleep Medicine, half of women aged 45 to 64 said menopause sometimes, often or always disrupted their sleep. Several changes can stack up at bedtime.

Falling progesterone. The Office on Women's Health says low levels of progesterone can make it hard to fall asleep and stay asleep. As ovulation becomes less regular in perimenopause, progesterone levels fall and fluctuate.

Hot flashes and night sweats. A flash as you're drifting off can jolt you back awake. Sleep specialists at the American Academy of Sleep Medicine note that hot flashes and night sweats can make it hard to fall asleep and stay asleep. Our guide to perimenopause night sweats covers them in more detail.

A racing, anxious mind. New or stronger anxiety is common in perimenopause, and bedtime is often the first quiet moment of the day. There's more on this in our guide to perimenopause anxiety.

Habits that grow around bad nights. After a run of poor sleep, it's natural to go to bed earlier, lie in or nap. These can make it harder to feel sleepy at bedtime.

Other causes. Stress, caffeine, nicotine, alcohol, some medical conditions and some medicines can all get in the way of sleep. The National Heart, Lung, and Blood Institute says women's risk of sleep apnea rises during and after menopause, and that sleep apnea and menopause can share symptoms such as insomnia, headaches and fatigue.

When does it become chronic insomnia? Short-term insomnia usually lasts days or weeks and is often tied to stress or a change in routine.

The National Heart, Lung, and Blood Institute describes chronic insomnia as trouble sleeping that happens three or more nights a week, lasts more than three months, and can't be fully explained by another health problem. It notes that chronic insomnia can affect memory and concentration.

Insomnia isn't a willpower problem. It's a pattern your brain has learned, and patterns can be relearned.

CBT-I: the first-line treatment for perimenopause insomnia

In 2016, the American College of Physicians recommended that all adults with chronic insomnia receive cognitive behavioral therapy for insomnia (CBT-I) as the initial treatment. The American Academy of Sleep Medicine's clinical guideline also makes a strong recommendation for CBT-I in adults with chronic insomnia.

CBT-I is a structured, short-term program, typically delivered over four to eight sessions, according to the American Academy of Sleep Medicine. It usually combines several parts.

Stimulus control. This means going to bed only when sleepy and getting up if you can't sleep, so your brain relinks bed with sleep.

Sleep restriction. For a while, you limit time in bed to roughly the time you're actually sleeping. It sounds harsh, but it builds sleep pressure so you fall asleep more easily. It's done with guidance from a trained clinician.

Relaxation and cognitive work. You learn ways to calm your body and question the worried thoughts that keep you awake.

The American Academy of Sleep Medicine advises that sleep hygiene tips alone shouldn't be used as the only treatment for chronic insomnia. Ask your doctor about a referral to a clinician trained in CBT-I. The Menopause Society also recommends CBT for hot flashes, so this kind of therapy may help on more than one front.

Sleep habits, alcohol and caffeine

These habits won't fix chronic insomnia by themselves, but they support everything else.

Keep a steady wake-up time. Get up around the same time every day, even after a poor night. Lying in usually makes the next bedtime harder.

Get up if you can't sleep. MedlinePlus suggests that if you can't fall asleep within 30 minutes, you get up and move to another room. Do something calm in dim light and go back to bed when you feel sleepy.

Watch the caffeine. Coffee, tea, cola and energy drinks all contain caffeine. MedlinePlus advises avoiding caffeine in the evening, and you may find an earlier cutoff helps.

Rethink the nightcap. Alcohol may make you drowsy, but it can disturb sleep later in the night, and MedlinePlus advises avoiding it in the evening. Some women also find it triggers night sweats.

Wind down away from screens. MedlinePlus advises against watching TV or using a computer near the time you want to fall asleep, and the American Academy of Sleep Medicine suggests keeping the bedroom quiet, dark and cool.

A caution about sleeping pills

The American College of Physicians recommends that doctors consider adding medicine only when CBT-I alone hasn't worked, after talking through the benefits, harms and costs of short-term use.

In 2019, the FDA added its most prominent boxed warning to eszopiclone (Lunesta), zaleplon (Sonata) and zolpidem (Ambien) after rare but serious injuries and deaths linked to complex sleep behaviors, such as sleepwalking and sleep driving. The FDA advises not drinking alcohol before taking these medicines.

Over-the-counter options aren't automatically safer. Melatonin is sold as a dietary supplement in the US, and the National Center for Complementary and Integrative Health says there isn't enough strong evidence to recommend it for chronic insomnia. A 2023 study found that 22 of 25 melatonin gummy products were inaccurately labeled. Check with a pharmacist or your doctor before taking any sleep aid, especially alongside other medicines.

If night sweats are what's keeping you up, treating them may help. The Menopause Society calls hormone therapy the most effective treatment for bothersome hot flashes, and easing them may improve sleep. Our article on hormone therapy for perimenopause sets out the evidence.

When to talk to a doctor

See your doctor if trouble sleeping lasts more than a few weeks and affects your work, mood or relationships. Also see your doctor if a partner notices loud snoring, gasping or pauses in your breathing, if you wake with headaches, or if you feel sleepy while driving.

Talk to your doctor too if you feel low, flat or hopeless most days, as sleep problems can be part of depression. If you have thoughts of harming yourself, call or text 988 (the Suicide & Crisis Lifeline). Call 911 in an emergency.

Frequently asked questions

Can perimenopause cause insomnia?

Yes. The Office on Women's Health says low progesterone can make it hard to fall and stay asleep, and hot flashes and night sweats can disrupt sleep too. If poor sleep is affecting your days, talk to your doctor.

How can I fall asleep faster in perimenopause?

Go to bed when you feel sleepy, not at a set early time. If you can't fall asleep within about 30 minutes, get up and do something calm until you're sleepy. Cutting evening caffeine and alcohol can help too.

Does melatonin help perimenopause insomnia?

The National Center for Complementary and Integrative Health says there isn't enough strong evidence to recommend melatonin for chronic insomnia. It's sold as a supplement, so products can vary. Ask your doctor or pharmacist before trying it.

Is CBT-I better than sleeping pills?

The American College of Physicians recommends CBT-I as the first treatment for chronic insomnia in adults, and suggests considering medicine only if CBT-I alone hasn't worked. CBT-I works on the habits and thoughts that keep insomnia going, rather than sedating you for the night.

Your next step

Starting tonight, keep a simple two-week sleep diary: when you went to bed, roughly how long it took to fall asleep, how often you woke and when you got up. It turns a vague sense of bad nights into a clear pattern you can share with your doctor. Our guide to talking to your doctor about perimenopause can help you plan the appointment.
