Why I prioritise sleep in clinic for my clients going through perimenopause/menopause...

It’s 3am. You’re wide awake. Your heart is beating a little too fast, your mind has already started running through tomorrow’s to-do list, and you’re too warm despite the window being open. You finally fall back asleep around 5am... just in time for the alarm to go off.

This is a common pattern I see in clinic and have experienced myself during this season of life.

Sleep disruption is one of the most common and most debilitating experiences women report during perimenopause.

In clinical practice, sleep is one of the first things I address with perimenopausal clients because it is often an upstream contributing factor to almost everything else presenting. Poor sleep drives fatigue, amplifies stress reactivity, disrupts appetite regulation, impairs metabolic function, reduces recovery leading to injury vulnerability and compounds mood instability. You cannot sustainably support health and wellbeing in a woman who isn’t sleeping. Everything else we do therapeutically is built on this foundation.

Why Perimenopause Disrupts Sleep

Sleep architecture is hormonally regulated. During perimenopause, the fluctuating and gradual decline of oestrogen and progesterone creates a cascade of changes that make restorative sleep significantly harder to achieve.

Progesterone has a direct sedating effect. It acts on GABA-A receptors in the brain, the same receptors targeted by anti-anxiety medications. As progesterone declines in perimenopause (often before oestrogen), this natural calming effect is diminished. Women frequently describe this as a new inability to “switch off” at night, or as waking in the early hours with a sense of anxiety or restlessness that didn’t exist before.

Oestrogen plays a key role in thermoregulation via the hypothalamus. Declining oestrogen narrows the thermoneutral zone (the temperature range in which the body feels comfortable) making women more susceptible to vasomotor symptoms such as hot flushes and night sweats. Even subclinical temperature dysregulation can fragment sleep and reduce slow-wave (deep) and REM sleep.

HPA axis reactivity also increases as oestrogen declines. Oestrogen normally exerts a moderating influence on cortisol output; without it, the stress response becomes more sensitive and harder to downregulate. Evening cortisol that should be low can stay elevated, keeping the nervous system in a state of arousal that directly interferes with sleep onset and maintenance.

The result is a perfect storm: reduced GABAergic calm, temperature instability, and a dysregulated stress response.

A Naturopathic Approach to Sleep during Perimenopause

There is no single intervention that will fix perimenopausal sleep disruption and anyone claiming otherwise is oversimplifying. What works is a layered, consistent approach that addresses the underlying drivers. Here’s where I often start clinically.

1. Sleep Hygiene

Generic sleep hygiene advice

The following are important foundations:

• Keep the bedroom cool. Given the narrowed thermoneutral zone, ambient temperature matters more than ever. Aim for 16–19°C. Breathable, natural-fibre bedding helps considerably.

  
  

• Protect morning light exposure. Bright natural light in the first hour after waking anchors your circadian clock and supports the cortisol awakening response, which in turn supports melatonin production that evening. This is particularly important when HPA dysregulation is in the picture.

  
  

• Create a genuine wind-down window. This is usually the hardest for people to implement along with boundaries around devices. A minimum of 60 minutes before bed without bright overhead lighting, screens, or cognitively demanding tasks. Giving the nervous system a signal that the day is ending, helps shift it out of survival mode into recovery mode.

  
  

• Limit alcohol. Alcohol disrupts sleep architecture significantly, particularly REM sleep and sleep in the second half of the night. In perimenopause, where sleep is already fragile, even one to two standard drinks can meaningfully worsen sleep quality. This is not always what clients want to hear, but the evidence is clear.

  
  

2. Nutrition for Circadian and Sleep Support

What and when you eat has a direct bearing on sleep quality (a connection that is frequently overlooked).

• Eat regular, balanced meals throughout the day. Skipping meals or eating reactively/erratically creates blood glucose instability that dysregulates cortisol, particularly in the evening. A small blood sugar dip at 2–3am is a common driver of the classic perimenopausal night waking. Prioritising protein and fat at dinner can support overnight glucose stability.

  
  

• Include tryptophan-rich foods. Tryptophan is the precursor to serotonin and melatonin. Good sources include turkey, eggs, dairy, nuts, seeds, and oats. Pairing these with a small amount of complex carbohydrate in the evening supports tryptophan transport across the blood-brain barrier.

  
  

• Reduce stimulants after midday. Caffeine has a half-life of approximately five to even 12 hours for many people. A 2pm coffee can still meaningfully elevate circulating caffeine at 9pm, competing directly with adenosine (your sleep-pressure signal). In women with HPA dysregulation, caffeine sensitivity is often heightened.

  
  

3. Exercise

Regular physical activity is one of the most evidence-supported interventions for sleep quality in perimenopausal women. It supports slow-wave sleep, reduces anxiety and HPA reactivity, improves thermoregulation, and supports body composition.

• FIRST - Any movement/exercise is better than none - doing something is better than nothing.

• Morning or early afternoon exercise may support sleep better than late evening training, which can delay sleep onset in some women with already-elevated evening cortisol.

• A combination of resistance training and moderate-intensity aerobic exercise appears most beneficial for both sleep and hormonal health in this cohort.

• Gentle evening movement (a 20-minute walk, yoga, or stretching) can support nervous system downregulation without the cortisol-raising effect of intense training.

  
  

4. Targeted Supplementation

Supplementation works best layered on top of solid foundations, not instead of them. That said, two common things I often recommend that have good evidence and are particularly relevant to perimenopausal sleep include:

• Magnesium glycinate is my most consistently clinically useful supplement for sleep in this population. Magnesium supports GABA activity (directly relevant given declining progesterone), modulates HPA reactivity, and supports muscle relaxation. The glycinate form has superior bioavailability and tolerability compared to other forms. Meta-analyses support magnesium supplementation for improving subjective sleep quality, particularly in adults with low dietary intake. A typical therapeutic dose is 300–400mg elemental magnesium as glycinate, taken 60–90 minutes before bed.

  
  

• Withania somnifera  is an adaptogenic herb with a well-characterised HPA-modulating mechanism, which is directly relevant to the elevated evening cortisol and stress hyperreactivity that can often contribute to perimenopausal sleep disruption. Research has suggested that 600mg of ashwagandha root extract taken daily can significantly improve sleep quality, sleep onset latency, and total sleep time compared to placebo in adults with insomnia. It also has been found to reduce perceived anxiety (addressing the “wired but tired” presentation that is so common). It is well-tolerated for most women at standard doses, though it is worth noting it should be used cautiously in thyroid conditions. Having a chat with a registered herbalist is always a good idea:)

A Note on Menopausal Hormone Therapy (MHT)

For women with significant vasomotor symptoms driving sleep disruption, MHT can be genuinely effective and is worth a conversation with your GP or gynaecologist. MHT isn’t appropriate for everyone, and it isn’t a sleep hygiene replacement but for many women where it is warranted, it removes a significant physiological barrier that makes everything else more effective.

In summary, perimenopausal sleep disruption is not something you simply have to endure. Sleep is a critical pillar for health and needs to be protected and supported.

Key takeaways

• ALWAYS start with and prioritise the the foundations: temperature, light, wind-down routine, and alcohol reduction.

• Layer in regular meals, morning movement, and targeted supplementation.

• And if vasomotor symptoms continue to drive significant disruption, have an honest conversation with your GP about whether MHT is appropriate for you.

If you’ve tried the basics and you’re still struggling, it’s worth working with a practitioner who can assess the full clinical picture including cortisol patterns, nutrient status, and any underlying drivers that a generic protocol won’t reach.
