Key Highlights
- Poor sleep in menopause usually has a physical cause — and often more than one
- Thyroid problems are one of the most common causes of insomnia in women, and most go undiagnosed
- A gene variant called MTHFR can reduce how much melatonin your body makes
- Blood sugar drops at night can wake you up just as effectively as a hot flash
- Your stress response and your body temperature are more connected than you think
- Most women are low in key nutrients that directly affect sleep — and have no idea
You Are Not Imagining It
You go to bed exhausted. You wake up at 2am and your mind is going. Or you sleep eight hours and feel like you slept three. You have tried everything — no screens before bed, magnesium, melatonin, going to bed earlier. Nothing sticks.
And so you assume it is just part of getting older. Or that you are more stressed than you realize. Or that your body has just changed and this is what sleep looks like now.
Here is what I want you to know after 22 years of working with women in menopause: that is almost never the full story. There are specific, physical reasons your sleep has fallen apart. Most of them are identifiable. Most of them are fixable. And most of them are never checked.
I see women who have been managing broken sleep for years — sometimes a decade or more — who had no idea there was something underneath it that nobody had ever looked for. Once we find it and address it, sleep changes. Sometimes within weeks.
These are the six things I look at first.
1. Your Thyroid
Insomnia is one of the most common symptoms of thyroid problems in women. And a very high percentage of women with subclinical hypothyroidism — meaning their thyroid is underperforming but not severely enough to show up on a basic test — never know they have it. It never gets found. It never gets treated.
I have spoken to women who have not slept through the night in years. Years and years. And when we look more carefully at their thyroid, there it is. Sometimes that is the only thing wrong. The sleep problem had one cause, and nobody had ever looked closely enough to find it.
A standard thyroid test gives you a very limited picture. A more complete evaluation tells a different story entirely. If your sleep has been off for a long time and you have never had a thorough thyroid workup, that is one of the first places I would look.
2. Your Stress Response
When your body is under stress — even the kind you do not consciously feel — it responds. And one of the ways it responds at night is through temperature dysregulation.
A heightened stress response can trigger a rise in body temperature while you sleep. That can cause a night sweat that wakes you up. This is why some women have night sweats that are not purely hormonal — the stress response is driving them, sometimes triggered by something as simple as a blood sugar drop in the middle of the night.
This is not about being a stressed-out person. It is about what your body is doing while you sleep, and whether your nervous system is calm enough to let you stay there.
3. Blood Sugar
When your blood sugar drops during the night, your body sends out an alarm signal to bring it back up. That signal wakes you up — often with a racing heart, a jolt out of a sound sleep, or a sudden feeling of alertness at 2am when you should be deeply asleep.
In menopause, blood sugar becomes less stable. What you eat at dinner, whether you had alcohol, how long it has been since you last ate — all of it can affect whether your blood sugar holds steady through the night or drops and triggers that wake-up call.
Women who wake up at the same time every night feeling alert and activated rather than groggy often have this going on. It is one of the first things I look at.
4. MTHFR Status
MTHFR is a gene variant that affects how your body processes certain B vitamins. It is very common — many women have it and have never heard of it.
Why does it matter for sleep? Because it can reduce how much melatonin your body is able to produce. Melatonin is what signals your brain that it is time to sleep. If your body cannot make enough of it, falling asleep and staying asleep becomes genuinely harder — not because of anything you are doing wrong, but because of how your body is built.
This is something that can be checked and specifically addressed. It just rarely makes it onto anyone's radar.
5. Nutrient Deficiencies
Sleep does not happen on its own. Your body needs specific nutrients to produce the hormones and brain chemicals that make sleep possible. When those nutrients are low, the whole system gets wobbly.
Most women in menopause are running low on at least a few key ones without realizing it. They are eating well, doing the right things, and still not sleeping — because a deficiency they do not know about is quietly working against them in the background.
This is not about taking a general multivitamin and hoping for the best. It is about finding out specifically what your body is missing and addressing it directly. When you do, the difference in how you sleep — and how you feel overall — can be significant.
6. Screens and Light Exposure
Your body uses light as its primary signal for when to be awake and when to wind down. When the sun sets, your brain is supposed to start producing melatonin. But light from your phone, your TV, or bright overhead lights in the evening tells your brain it is still daytime. Melatonin gets suppressed. Your body stays alert when it should be preparing for sleep.
Most people know this already. The difference in menopause is that your body is already working against you in other ways — and adding light disruption on top of that compounds everything. If you are dealing with any of the other five things on this list and also getting a lot of screen time in the evening, you are making a hard situation harder.
Protecting your light environment in the two hours before bed is one of the simplest, most accessible things you can do that actually makes a real difference.
A Patient Story
A 57-year-old woman from Portola Valley came to see me after struggling with sleep for close to four years. She was waking up every night between 1 and 2am, lying there for an hour or two, and then dragging herself through the next day. She had been to her doctor. Her labs came back normal. She was told it was probably stress and maybe perimenopause.
When I looked at her more carefully, I found two things: her thyroid was underperforming in a way the standard test had not caught, and she had an MTHFR variant that was limiting her melatonin production. Nobody had ever checked either one.
We addressed both. Within about a month she was sleeping through the night consistently for the first time in years. Not because we did anything dramatic — because we finally found what was actually wrong.
Details have been changed to protect patient privacy. The clinical outcome is real.
What This Means for You
If you have been struggling with sleep and feel like you have tried everything, the problem is most likely not that you are doing something wrong. The problem is that nobody has looked at the right things yet.
Most women I see with poor sleep in menopause have more than one of these six factors working against them at the same time. When we identify which ones are present and address them, sleep improves. And when sleep improves, so does everything else — your energy, your weight, your mood, your ability to think clearly.
You do not have to keep white-knuckling your way through tired days. There is usually a reason this is happening, and there is usually something we can do about it.

Frequently Asked Questions
Why do I wake up at the same time every night?
A consistent wake time — especially between 1am and 4am — almost always has a physical cause. The most common ones are a blood sugar drop that triggers your body's alarm response, or a stress response that spikes during the night. Both are identifiable. Both are addressable. The consistent timing is actually a clue, not just a frustrating coincidence.
Will hormone therapy fix my sleep?
It helps some women significantly, especially when hormones are the primary driver. But it does not address thyroid function, blood sugar, MTHFR status, nutrient deficiencies, or your stress response. Women who are still not sleeping well on hormone therapy usually have one of these other pieces that has never been identified.
Why am I exhausted even when I get 8 hours of sleep?
Hours in bed are not the same as quality sleep. If your thyroid is underactive, if you are low in key nutrients, or if your body is briefly waking itself up and going back to sleep without you fully knowing it, you can spend a long time in bed and still feel terrible. The number of hours is not the problem — what is happening during those hours is.
What supplements actually help with sleep in menopause?
It depends entirely on what your body is specifically missing. There is no universal answer. A supplement that makes a significant difference for one woman does nothing for another because the underlying cause is different. Finding out what your body actually needs is more useful than trying things randomly and hoping something works.
