When Maya turned 47 she blamed the extra pounds on late nights and too much chai. By day she taught high school biology; by night she scrolled through lesson plans and then—because she’d “only” have 30 more minutes—her phone. For months the scale crept up, her jeans fit tighter around the middle, and most nights she woke at 3 a.m., hot and restless. At first she told herself it was stress. Then a friend said, “Have you thought about perimenopause?” and a conversation that had seemed decades away suddenly had an urgent, very modern soundtrack: sleep apps, TikTok threads, and a string of people searching “why can’t I sleep during menopause?”
Disrupted sleep is a really common issue during perimenopause and menopause – and it’s a symptom I get asked about a lot , including during a phone-in I did recently on @thismorning.
The hormones oestrogen and testosterone both have important effects on your brain, including helping the quality and duration of sleep. Low oestrogen levels can lead to sleep problems but also cause fatigue, difficulty concentrating, headaches, weight gain, and mood changes, and a lack of sleep can further exacerbate these symptoms.
Replacing the hormones oestrogen, progesterone, and (if needed) testosterone, helps many women sleep better as taking HRT deals with the hormonal cause of the insomnia and reduces the symptoms that might wake you up, for example, night sweats, stress and anxiety, or frequent urination. Women often notice they can fall asleep quicker and wake up during the night far fewer times, or even sleep through the night.

Maya’s story isn’t rare. For many midlife women, sleep troubles, shifting weight, and mood changes arrive together — and together they make everything feel harder to handle. This piece pulls the science into a human story and gives practical steps that actually help.
What’s actually happening: the biology in plain English
As women move through perimenopause into menopause, ovarian hormone production (especially estrogen and progesterone) becomes irregular and then declines. Those hormones do a lot more than regulate periods — they help keep body temperature steady, support restorative sleep, and influence where the body stores fat. That hormonal roller coaster can trigger hot flashes, night sweats, mood swings, and insomnia — and those sleep disturbances are tightly linked to weight gain and changes in body composition during midlife.
Key numbers to hold on to:
- Large reviews estimate about half of menopausal or postmenopausal women report clinically meaningful sleep problems (a pooled prevalence around 51% in some meta-analyses).
- Many studies show women often gain roughly 1–1.5 pounds (≈0.5–0.7 kg) per year during midlife, with roughly 20% gaining 10+ pounds through the transition — and abdominal fat tends to rise even if total weight change is modest.
Those aren’t just numbers: they’re the population version of Maya’s jeans suddenly feeling snug.
How poor sleep fuels weight gain
Sleep and metabolism talk to each other constantly. Short or poor sleep alters hunger hormones (raising ghrelin, lowering leptin), increases cravings for calorie-dense foods, impairs glucose metabolism, and reduces the energy and motivation many people need to exercise. Experimental and population studies link short sleep with a higher risk of obesity and future weight gain, so repeated nights of fragmented sleep during perimenopause can tilt the energy balance toward weight gain.
A dramatic lab study even showed that one night without sleep produced measurable changes in hormones and signals that favor fat storage and muscle breakdown — a reminder that sleep loss works on the body quickly.
The “menopause puzzle”: it’s rarely only hormones
It’s tempting to say “hormones did it” and move on, but the real picture is layered:
- Hormonal changes (hot flashes, night sweats) directly disrupt sleep.1
- Aging itself reduces muscle mass and basal metabolic rate, making it easier to gain fat and harder to hold on to lean mass.2
- Lifestyle shifts — less time for structured workouts, busier work/family life, and stress — compound the effect.
- Mental health: anxiety and depression both worsen sleep and appetite regulation; they’re more likely in midlife for many people.3
So the solution rarely looks like a single pill. It’s a multi-front approach.
Evidence-backed strategies that help (what Maya actually did)
1. Treat the sleep problem directly (not “wait and see”)
If sleep is consistently poor for weeks or months, it’s worth treating the sleep disorder itself. Cognitive Behavioral Therapy for Insomnia (CBT-I) is the first-line, non-drug approach with strong evidence. For women whose sleep disruption is driven mainly by hot flashes, menopausal hormone therapy (when appropriate and prescribed) can meaningfully improve sleep quality. Clinical reviews and trials show hormone therapy reduces vasomotor symptoms and improves sleep for many women with these symptoms. Always discuss risks/benefits with a clinician.45
2. Prioritize “sleep hygiene” that actually matters
This isn’t about making a Pinterest bedroom — focus on high-impact behaviors: consistent sleep/wake times, limiting caffeine after midday, keeping the bedroom cool (helps with night sweats), and avoiding heavy meals and alcohol close to bedtime. For many women, reducing evening alcohol and late-night screen use reduces awakenings and next-day hunger.
3. Rebuild strength, not only cardio
Resistance training helps preserve muscle mass (which tends to decline after 30) and boosts resting metabolism. Even twice-weekly strength sessions can slow the change in body composition that happens during midlife.6
4. Use food strategies that work with hormonal shifts
Aim for protein at each meal, prioritize fiber and whole foods to support satiety, and beware of “calorie creep” from nighttime snacking after poor sleep. Small, practical changes beat dramatic but unsustainable diets.
5. Address mental health and stress
Anxiety and poor mood both worsen sleep and increase emotional eating. Mindfulness, therapy, and social support can reduce the burden of symptoms and improve sleep continuity.
6. Medical options — discuss with a clinician
For some women, hormone therapy, certain antidepressants that reduce hot flashes, or (in select cases) weight-loss medications are appropriate. These have benefits and trade-offs; medical decisions should be individualized. Recent conversations in medicine also include GLP-1 drugs (like semaglutide) for weight management in midlife women — promising for some, but not a universal fix.7
Quick, evidence-based checklist to try this month
- Keep a 2-week sleep log: bedtime, wake time, awakenings, naps, alcohol, caffeine.
- Make the bedroom ≤ 19–21°C (65–70°F) if night sweats wake you.
- Cut caffeine after 2 p.m.; stop screen time 60 minutes before bed.
- Add two 25–30 minute resistance sessions per week (bodyweight, bands, or gym).
- If hot flashes + insomnia persist → book a consultation with a clinician to discuss options (CBT-I, hormone therapy, or other meds).8
When to seek help — and what to expect
If poor sleep lasts more than a month and affects daytime functioning (work, mood, concentration), don’t wait. Primary care and gynecology providers can evaluate for specific causes (sleep apnea, thyroid disease, mood disorders, medication effects, or vasomotor symptoms). Treatments range from behavioral therapies and sleep specialists (for CBT-I) to targeted hormone or non-hormone medical therapies when appropriate. The recent large surveys of perimenopausal women show many feel unprepared and under-supported — asking for help early changes outcomes.910
Back to Maya: small changes, real results
Maya started by tracking sleep and symptoms for two weeks — she realized the nights she drank wine and graded papers late were her worst. She added a 20-minute resistance routine three times a week, turned her bedroom thermostat down, and asked her doctor about CBT-I. Within two months her night awakenings dropped and her midsection stopped expanding. The scale didn’t magically reverse, but she slept longer, felt less hungry between meals, and had more energy to walk after work. She calls it “boring changes that added up.”
Takeaway: sleep is not optional — it’s part of midlife care
For many women, perimenopause brings a convergence of symptoms that make sleep and weight management harder. But evidence shows sleep problems are common (affecting roughly half of women in the menopausal transition), sleep loss promotes weight gain, and treating sleep — whether with behavioral therapy, targeted medical options, or lifestyle changes — can meaningfully improve quality of life and metabolic health. If sleep is the weak link in your chain, fixing it can help everything else fall into place.11
