If you cannot remember the last time you woke up feeling genuinely rested, this is for you. Your children may still be waking at night, or they may have been sleeping through for years – yet you still feel exhausted, and your sleep is light You may be having night sweats, brain fog, or heavy periods so you are wondering if this is early perimenopause.

This article will help you understand what is actually going on – and what you can do about it.

Chronic sleep deprivation and burnout are modern epidemics, and they affect women disproportionately. This is not surprising – most mothers are simultaneously raising children, sometimes also caring for elderly parents, working, running a household, and holding everything together – all on broken sleep and very little genuine support. 

My own experience

Between my three children, I spent seven years either pregnant, breastfeeding, or both – with no family support nearby. By the time my third baby, who woke over ten times each night, was six months old, my immunity was low and I developed dramatic swelling in my feet. My GP ran tests and…everything came back ‘normal’. When I ran my own DUTCH test, the picture became clear – my cortisol was dysregulated. Not a dramatic diagnosis, but a useful insight into what was really driving my symptoms: long-term lack of sleep and chronic stress.

This is the most common pattern I see in practice. And it is almost always missed in conventional medicine – both in testing and in treatment.

This is not just about mothers of babies.

Postnatal depletion and burnout from lack of sleep, if left unaddressed, can persist for years. You may be experiencing postnatal depletion even if your youngest is already ten years old. It affects everything – the immune system, hormones, the gut, and the brain.

Women often come to me assuming they are in early perimenopause – the symptoms of burnout look remarkably similar: disrupted sleep, fatigue, gushing periods, anxiety, brain fog, recurrent infections. But quite often the deeper picture is one of long-standing postnatal depletion and dysregulated cortisol that was never properly addressed. This is why I test where possible. Time and again I see women with all reproductive hormones in a good range – but completely dysregulated, often floored cortisol and low melatonin. Understanding what is actually driving your symptoms changes everything about how we approach your recovery.

What is actually happening in your body:

Cortisol is your primary stress hormone. In the right amounts it is essential – it gets you out of bed in the morning, helps you respond to daily demands, and manages inflammation. But it was never designed to be chronically dysregulated, and years of broken sleep do exactly that.

What suffers most in the process is progesterone – your calming, neuroprotective hormone that supports deep sleep, steadies mood, and buffers against stress and anxiety. It is one of the first hormones to drop under sustained pressure – which is why so many women feel not just exhausted, but emotionally raw and unable to wind down. This is why so many women feel dramatically better on progesterone creams (and this is exactly why these are becoming so popular) – the relief is real, but it does nothing to resolve the underlying pattern.

When cortisol is dysregulated, you may experience:

• Fatigue that sleep doesn’t seem to fix
• A constant background hum of anxiety
• Wired but tired – unable to wind down even when desperate for sleep
• Irritability and emotional rawness that affects your relationships
• Brain fog
• Poor immunity – frequent UTIs, yeast infections, or cold sores
• Puffy feet and oedema
• Digestive problems and new food sensitivities
• Heavy or irregular periods
• Low libido, low mood, low motivation – low everything

These symptoms are not a malfunction. They are a message.

Fatigue in particular is your body’s intelligent adaptive response – a signal to stop and to rest. This is not the time to override that message with coffee on an empty stomach, energy supplements, or the latest biohacking products. They may give you a short burst of energy, but they drive the body harder precisely when it needs to be nourished and restored.

Real, lasting energy comes from real food, real sleep, and real rest. Unfortunately, there are no shortcuts.

Lack of sleep also accelerates ageing, and accelerates the onset of menopause, and – through sustained inflammation – can become a driver of serious illness over time, including autoimmune conditions such as Hashimoto’s thyroiditis. It is no coincidence that Hashimoto’s so frequently surfaces around six months postpartum, when sleep deprivation is at its most sustained and the immune system at its most vulnerable.

What’s causing your brain fog?

While you sleep, your brain runs its own nightly cleaning cycle through the glymphatic system – clearing waste products via cerebrospinal fluid movement. When sleep is chronically fragmented, this process is significantly impaired – and the result is a literal accumulation of neurological debris in brain tissue. 

This is not “just motherhood.” Nature never designed mothers to have brain fog – mothers need optimal cognitive function to be able to care for their children. 

Sleeping on your left side where possible supports the glymphatic system to work more efficiently than sleeping on your back. Even when lying awake, or during a daytime nap, try to stay on your side.

Real healing has to be holistic.

Recovery from chronic sleep deprivation and burnout is not about finding the right supplement. It has to be holistic – physical, emotional, and energetic.

I often find with clients that until we address sleep, nothing else shifts in a meaningful way.

What I use and recommend.

Morning light and nature. No amount of supplements can overcome the power of circadian biology – and sunlight is its most powerful anchor. Morning light regulates your cortisol rhythm and supports melatonin production at night, acting as a direct nutrient for your mitochondria – the energy centres of every cell. Even fifteen minutes outside in the morning, changes the chemistry of your day.

Carve time for yourself. Fifteen minutes every day – sitting, walking, having a bath, just being without anyone needing anything from you – is a clinical recommendation, not a luxury. It cannot be replaced by any supplement.

Your sleep environment matters. Modern LED lighting spikes in the blue light range, suppressing melatonin. Dim your lights after 8pm, stay off screens for at least two hours before bed, and consider swapping bedroom bulbs for low blue light amber or red alternatives. Blue light blocking glasses are a great solution when screens are unavoidable. Turn the WiFi router off at night too as EMFs from devices may further interfere with melatonin production. We heal during sleep, so the environment in which we sleep matters enormously.

Get to bed before 10.30pm. Sleep before 11pm is significantly more restorative than the same hours after midnight. The Traditional Chinese Medicine body clock supports this – in TCM, the gallbladder begins its restorative work at 11pm so if you are still awake during that time your body will not be able to restore optimally.

Swap HIIT for gentle movement. Intense exercise – running, high-intensity training, heavy lifting – further depletes already low cortisol reserves. I see many exhausted mothers pushing themselves harder, believing it will help with energy or weight. During burnout and postnatal depletion, low-intensity movement is genuinely therapeutic – walking in nature, yoga, Pilates, gentle swimming. These support cortisol recovery, calm the nervous system, and rebuild energy rather than spending it. When you begin to sleep better, any excess weight will most likely come off too.

Eat real, nourishing food. Nutrient deficiencies directly contribute to burnout and poor sleep – and this is consistently underestimated. Depleted mothers need the most bioavailable forms of key nutrients – complete protein, B12, iron, zinc, omega-3 fatty acids, and fat-soluble vitamins – found in their most absorbable forms in eggs, good quality meat, oily fish, liver, and bone broth. B12 deficiency alone can cause profound fatigue, disrupted sleep, and neurological symptoms. Most women need significantly more protein than they eat, starting at breakfast – which is not the time for toast or granola. Nutrition needs to be personalised to your life stage, your symptoms, and whether you are breastfeeding.

Drink chamonile, nettle and other restorative calming teas like butterfly pea in the evening.

Magnesium is one of the most important and most overlooked nutrients for exhausted mothers – and most women are deficient, because chronic stress depletes it rapidly. The best food sources are dark leafy greens, pumpkin seeds, dark chocolate, almonds, black beans, and avocado. As a supplement, magnesium glycinate is the most absorbable and gentle form – taken in the evening with food, it supports deep and restorative sleep. Many women need 500mg or more per day. Epsom salt baths are another deeply relaxing way to absorb magnesium through the skin – add one to two cups of salts to a warm bath, stir well, and soak for at least twenty minutes.

Adaptogens work intelligently with your body – drawing on them as and when needed, using only what is helpful. My favourite two adaptogens for depleted, sleep-deprived women are:

• Ashwagandha – its Sanskrit name means “strong as a horse” – is my most-used herb for exhausted mothers. Taken in the morning it builds resilience, taken in the evening, an hour before bed, it quietens mental chatter and supports deep sleep. In Ayurvedic medicine it is one of the primary herbs for rebuilding ojas – the deep reservoir of vitality – rather than simply stimulating energy that isn’t there.
• Shatavari – the Queen of Herbs – is my other go-to for depleted mothers, useful throughout a woman’s entire reproductive life – from postnatal recovery through to perimenopause – supporting mood, sleep, low libido, fatigue, and breast milk production. Ashwagandha and shatavari work beautifully together. Both are safe while breastfeeding.

Homeobotanical remedies – I blend these specifically for each client, working on physical, emotional, and energetic levels simultaneously. My go-to for sleep deprivation and burnout is a blend of Serena and Spectra – supporting restorative sleep, calming the nervous system, and helping you feel genuinely present in your body again. I also blend these for children waking at night due to the effects of a difficult birth.

Where appropriate I use the DUTCH test – which maps cortisol, progesterone, oestrogen, melatonin, and other key hormones across the full day and night, giving us a remarkably clear picture of what is actually happening and why. For some women, testing mitochondrial function or nutrient deficiencies are helpful also.

Recovery from burnout and chronic sleep deprivation is real and possible. But it requires a genuine, holistic, individualised approach – not a list of supplements to push through with.
