Sleep often changes during perimenopause. Frequent awakenings, night sweats, and insomnia can appear even in women who never experienced sleep problems before. Hormonal fluctuations, stress, and circadian rhythm disruption all play a role.

Why sleep changes during perimenopause

Estrogen and progesterone levels fluctuate irregularly, directly affecting the sleep center in the brain and thermoregulation. Lower hormone levels make body temperature control less stable, leading to night sweats and awakenings.

Progesterone promotes relaxation and sleep onset: its decline contributes to insomnia. Lower melatonin and higher evening cortisol levels further fragment sleep.

The most common sleep disorders: use them as a checklist

- Maintenance insomnia: frequent nighttime awakenings.  

- Difficulty falling asleep: racing thoughts, anxiety.  

- Unrefreshing sleep: tiredness despite sleeping hours.  

- Restless legs syndrome: involuntary leg movements.  

- Sleep apnea: may emerge or worsen after menopause.

Effects of poor sleep

Sleeping less than six hours regularly increases risk for hypertension, metabolic changes, mood swings, and cognitive decline. According to the Harvard Women’s Health Study (2022), chronic insomnia in perimenopause nearly doubles the risk of depression.

Evidence-based strategies to improve rest

1. Reset your circadian rhythm

Go to bed and wake up at consistent times. Avoid blue light and screens in the evening to encourage melatonin release.

2. Manage temperature and comfort

Keep the bedroom between 18–20 °C. Use breathable fabrics and lightweight bedding to minimize night sweats.

3. Nutrition and supplements

Reduce caffeine, alcohol, and sugar in the evening. Foods rich in magnesium, vitamin B6, and tryptophan promote serotonin and melatonin production.

4. Hormonal or non-hormonal support

The North American Menopause Society (2024) notes that hormone therapy can improve sleep by reducing vasomotor symptoms. Non-hormonal options like phytoestrogens and mindfulness have also shown benefits.

5. Stress management

Breathing techniques, yoga, and mindfulness help lower evening cortisol. *Frontiers in Psychology (2024)* found that eight weeks of mindfulness training significantly improved sleep quality in midlife women.

When to see a doctor

If insomnia persists for more than a month, affects mood, or coexists with intense symptoms, seek medical evaluation. A specialist can assess hormonal, metabolic, or respiratory causes and recommend tailored interventions.
