Sleep also plays an important role in maintaining healthy blood sugar levels.

Many women already notice a significant deterioration in their sleep during perimenopause. Diplom-Oecotrophologin Susanne Liedtke explains the role that hormones, blood sugar, and nutrition play in this — and which measures can demonstrably improve sleep quality.
Many women find themselves waking repeatedly during the night in menopause or struggling to fall asleep in the evenings. They often put it down to stress, but sleep disturbances can be among the first signs of hormonal changes. In their book Somebody told me, graduate nutritionist Susanne Liedtke and Dr. Christina Enzmann explain why nutrition can be a key factor in achieving greater well-being, energy, and better sleep during menopause.
In this interview, Susanne Liedtke, founder of the platform NOBODYTOLDME, discusses the causes of sleep problems and which measures can genuinely help women.
Do sleep disturbances begin as early as perimenopause?
Sleep disturbances can occur in some women very early in menopause, even before other typical symptoms such as hot flashes or mood swings appear. For some women, they may even be the very first sign that hormonal changes have begun.
In the early stages of menopause, known as perimenopause, women often struggle to fall and stay asleep. The troublesome night sweats typically appear later and further disrupt sleep.
However, hormonal changes are not the only factor affecting sleep. Sleep architecture also naturally changes as we age. The deep sleep and REM phases — during which sleep is most restorative — decrease, while the time it takes to fall asleep grows longer. Notably, this process affects men as well.
Anyone who suffers from sleep disturbances during menopause should not be too quick to blame hormones alone. A range of factors play a role and need to be considered in order to achieve restful sleep again.
A holistic approach is essential, as good sleep forms the foundation of health and well-being — particularly during this demanding phase of life.
Progesterone deficiency is often cited as the cause of sleep disturbances.
Contrary to widespread belief, it is not progesterone deficiency that triggers sleep disturbances during perimenopause. If that were the case, all women of reproductive age would experience sleep problems during the first half of their cycle, when progesterone levels are physiologically low. The exact causes have not yet been fully established, but research suggests that other factors play a more significant role.

Experts suspect that peaks in FSH — follicle-stimulating hormone — or the sharp fluctuations in hormone production that occur during menopause may be responsible for disrupting sleep quality.
Ovarian function undergoes significant changes during this phase of life, which can affect the entire body. The reason oral administration of bioidentical progesterone improves sleep in many women is that it is converted to allopregnanolone in the liver.
This metabolic byproduct can promote sleep by binding to GABA receptors in the brain. GABA is a neurotransmitter that induces relaxation.
Declining estrogen levels during menopause can also negatively affect sleep. For one thing, estrogen deficiency promotes hot flashes and night sweats.
These sudden temperature spikes can significantly disrupt sleep, causing frequent awakenings — and many women find it hard to fall back asleep afterward.
Frequent interruptions take a serious toll on sleep quality, leading to fatigue and difficulty concentrating during the day. Hot flashes and night sweats are therefore among the most common causes of sleep disturbances during menopause.
On the other hand, estrogen plays a key role in the production and breakdown of neurotransmitters such as serotonin and dopamine. When estrogen levels drop, this delicate system is thrown out of balance.
This can result in mood swings, low mood, and sleep disturbances. Melatonin levels are also affected by estrogen deficiency, which further contributes to difficulty falling asleep.
How are blood sugar levels and sleep connected?
Sleep plays an important role in maintaining a healthy blood sugar level. Getting restful sleep can help lower unhealthy blood sugar levels. Poor sleep — which affects many women during menopause — can have a direct impact on blood sugar levels. Among other things, sleep deprivation raises cortisol levels, which in turn drives blood sugar levels up.
Sleep deprivation has even been linked to diabetes. Compounding this, declining estrogen levels lead to increased insulin resistance. This means two factors are simultaneously driving blood sugar levels in the wrong direction: poor sleep and falling estrogen levels.
Just as sleep influences blood sugar levels, blood sugar levels can also affect sleep quality. A study of people with type 2 diabetes found that those with higher blood sugar levels tend to sleep worse.
Another study found that people with blood sugar levels in the prediabetes range are more likely to sleep poorly — 62% compared to 46% of people with normal blood sugar levels.
It is therefore important, by menopause at the latest, to step up everything that can help reduce elevated blood sugar levels — such as an anti-inflammatory diet, mindfulness, and exercise. Through the Body Reset courses you will learn how to prevent blood sugar spikes by making the right food choices.
What treatment options are available?
Hormones can be a helpful treatment option for sleep disturbances during menopause, but there is no one-size-fits-all solution. Every woman responds differently to hormone therapy, so it is important to try different approaches and find the right fit for each individual.
Orally administered bioidentical progesterone can have a sleep-promoting effect in women. This is because it is converted to allopregnanolone in the liver, which has a calming and sleep-inducing effect on the brain.
Are there alternative treatment methods?
Yes. Acupuncture, a traditional Chinese healing practice, can, for example, help regulate hormone balance and improve sleep quality. Homeopathy also offers a range of remedies that can be selected based on individual symptoms.
Many herbal remedies can also offer gentle and effective relief for sleep disturbances during menopause. Valerian, hops, lemon balm, passionflower, skullcap, chamomile, and California poppy have all proven their worth. These medicinal plants have a calming, relaxing, and sleep-promoting effect. Essential oils from lavender or lemon can also help promote relaxation.
Likewise, teas made from lemon balm, passionflower, St. John's wort, or black cohosh can help promote relaxation in the evening and make it easier to fall asleep.
Herbal sleep aids are not a quick fix, however: they can take some time to kick in and have a positive effect on sleep. There are also no scientific studies on their effectiveness to date.
Can diet alleviate sleep disturbances?
The right diet and a sleep-friendly lifestyle can help counteract sleep disturbances during menopause. Good sleep hygiene is a key factor in achieving restful sleep.
First and foremost, this means a cool, well-ventilated sleep environment. The ideal room temperature is between 16 and 18 degrees Celsius. Those prone to night sweats may find relief by wearing lightweight, breathable clothing made from natural materials.
Anyone who sleeps poorly should try reducing their caffeine intake for a period of time. For some women, even a single cup of coffee in the morning can negatively affect their sleep.
Fortunately, there are now many alternatives, such as decaffeinated coffee or cacao-mushroom blends. Tea, however — whether black, green, or white — also contains caffeine, so it is not a true alternative to coffee.
In the evenings, light meals with complex carbohydrates and some protein are recommended — for example, vegetable soups with legumes or quinoa with steamed vegetables.
A handful of cashew nuts can also help. They contain not only magnesium, which has a relaxing effect, but also tryptophan, which is needed for melatonin production. Pairing carbohydrates with tryptophan-rich foods at dinner is therefore a great combination for supporting the body's own melatonin production — and a solid foundation for a good night's sleep.
Adequate intake of vitamins and minerals is also important. Vitamin B6, B12 (taken in the morning), and magnesium(particularly magnesium glycinate taken in the evening) support healthy nervous system function and promote relaxation, while vitamin D contributes to normal muscle function.
When should you see a doctor?
If sleep disturbances persist over an extended period and affect your quality of life, it is worth seeing a doctor. A gynecologist or general practitioner can help identify possible causes and discuss appropriate treatment options.
