Perimenopause is the official transition into menopause, but for many women, it’s a time of significant physical and emotional challenges. During this phase, hormones start fluctuating unpredictably, affecting nearly every bodily function—especially sleep. Studies suggest that between 39% and 72% of women experience sleep issues related to perimenopause, such as waking up suddenly at night, hot flashes, or anxiety. Fortunately, there are ways to manage these symptoms, according to certified menopause specialist Dr. Christina Enzmann, who explains what happens during perimenopause and how to achieve restful sleep.
How Perimenopause Affects Sleep
As perimenopause begins, hormone production in the ovaries becomes irregular, starting with progesterone and later estrogen. These gradual changes disrupt key processes tied to the sleep-wake cycle. For instance, falling estrogen levels can impair the body’s ability to regulate temperature, leading to nighttime hot flashes and sweats that interrupt sleep. Additionally, hormonal shifts often increase cortisol, the primary stress hormone, which can disrupt the HPA axis (hypothalamic-pituitary-adrenal axis) and further disturb sleep. Many women feel exhausted in the evening but find themselves wide awake in bed, a state Dr. Enzmann describes as “tired but wired,” often accompanied by racing thoughts, stress, or restlessness.
Blood sugar also plays a role; significant fluctuations due to diet or stress can keep insulin levels high, raising cortisol and creating a cycle that severely impacts sleep quality. In summary, progesterone, estrogen, cortisol, and insulin interact closely during perimenopause, and even minor imbalances can greatly affect sleep.
Hormones and Their Roles
Progesterone acts as a natural sedative, calming the central nervous system and aiding sleep, but its decline reduces this effect. Estrogen helps maintain deep sleep and REM phases, stabilizes mood, and assists with temperature control. When these hormones drop or fluctuate, issues like difficulty falling asleep, nighttime awakenings, and sweats arise, often alongside higher cortisol and unstable blood sugar. These changes mean many women face significant sleep challenges during perimenopause.
When to Seek Help
It can be hard to tell if sleep problems are due to perimenopause or just stress. Dr. Enzmann advises taking sleep issues seriously if they last three to four weeks and interfere with daily life, such as causing concentration problems, emotional instability, or feeling overwhelmed. She emphasizes that sleep disturbances are often early signs of hormonal imbalance or chronic stress, not just a normal part of aging.
Common Mistakes
Many women turn to dietary supplements to improve sleep, but Dr. Enzmann cautions that not all sleep disorders are the same, and solutions vary. While magnesium (300 mg as glycinate), taurine (3 g), and a B-vitamin complex might help some, others may need targeted support like adaptogens (e.g., ashwagandha) for restlessness or anxiety. It’s important to consult a doctor for proper analysis and advice before trying any supplements.A common mistake is turning to sleeping pills. “Not only can they be addictive, but they can also reduce sleep quality,” Enzmann cautions. Having a glass of wine in the evening to unwind isn’t wise either: “While alcohol may help you fall asleep faster, it’s been shown to disrupt deep sleep stages, often leaving you feeling more tired the next morning.”
What truly helps
According to the expert, there are much better and longer-lasting ways to improve sleep during perimenopause. Medically, bioidentical hormone therapy (HRT), such as taking progesterone at night, can promote sleep for many women, especially if they’re also experiencing irregular cycles, mood swings, or hot flashes. “It’s just as important to stabilize cortisol levels through exercise, meditation, mindfulness, and proper nutrition,” Enzmann adds.
Establishing consistent evening habits like warm foot baths, using lavender, journaling, breathing exercises, or meditation can be beneficial. Avoiding late meals, alcohol, sugar, and screen time before bed also supports the body’s natural melatonin production. “Regular outdoor activity helps regulate your body clock, and an anti-inflammatory diet that keeps blood sugar steady is key for better sleep,” Enzmann points out.
Certain supplements, such as magnesium glycinate, taurine, L-theanine, or herbal adaptogens like rhodiola, may also be useful. But sometimes simple changes make a big difference: “A dark room or a sleep mask can work wonders,” Enzmann suggests. Similarly, setting aside electronic devices in the evening is helpful.
Perimenopause and melatonin
What about melatonin, often linked to good sleep? It can be especially effective if sleep issues are due to a disrupted sleep-wake cycle. “However, it should be taken in small doses; 0.3 to 1 mg is often enough,” Enzmann emphasizes. “Taking too much can ironically cause nighttime awakenings.”
Herbal remedies like valerian, passionflower, hops, or ashwagandha may also provide support, particularly for stress or inner restlessness. The right choice and combination depend on the individual.
Remember, “sleep problems during perimenopause aren’t a sign of weakness—they’re a signal that your body is adjusting,” Enzmann says. So it’s worthwhile to explore the underlying causes rather than just treating symptoms. Understanding how hormones, cortisol, blood sugar, and lifestyle interact allows you to make effective changes. This can have a broader impact: “When sleep improves, many other perimenopause and menopause symptoms often ease on their own,” Enzmann notes.
