“I used to be a morning person. Now I wake up already tired.” If that sounds familiar, keep reading.
By Jin Choi, Acupuncturist· Sydney, NSW·8 min read
In my clinic in Randwick, there’s a conversation I have almost every week. A woman in her early-to-mid 40s sits down across from me, and within the first few minutes she says something like: “I don’t know what’s wrong with me. I’m not doing anything differently, but I’m exhausted all the time.”
She’s usually sleeping the same hours she always did. She’s not running a marathon or working three jobs. But the tiredness she’s describing is different — heavier, harder to shake. Coffee helps for an hour. Then it doesn’t.
This is one of the most common presentations I see in women between 38 and 52, and the frustrating part is that it often flies under the radar in standard health checks. Iron levels come back fine. Thyroid is “normal.” The GP says to rest more and reduce stress.
But nothing changes.
So let’s actually talk about what’s going on.
It’s Not Just “Stress” — Your Body Is Shifting
The most significant thing happening in a woman’s body in her 40s is a gradual but real shift in hormone levels. Oestrogen and progesterone don’t drop off a cliff overnight — they start fluctuating years before menopause in a phase called perimenopause. This can begin as early as the late 30s and last a decade.
These hormonal fluctuations affect far more than just your cycle. They directly influence:
Sleep architecture — you may fall asleep easily but wake at 2 or 3am
Cortisol rhythms — your stress response becomes harder to regulate
Blood sugar stability — energy crashes more easily after meals
Mood and motivation — low progesterone can feel like low-level depression
Thyroid function — can be indirectly affected, even when TSH reads “normal”
Inflammatory response — the body becomes subtly more inflamed
None of these are catastrophic on their own. But stacked together, day after day? The cumulative effect is profound exhaustion — and it’s entirely real, not in your head.
From the clinic
“I often describe it to patients this way: your body is running three software updates simultaneously. It’s not broken — it’s occupied. The tiredness is a signal, not a flaw.”
The 5 Reasons This Exhaustion Feels Different
1. Sleep that doesn’t restore
Falling asleep isn’t the problem. It’s the quality of sleep. Low progesterone reduces deep, slow-wave sleep — the kind that actually repairs your nervous system. You wake up after 7 or 8 hours and still feel like you haven’t slept. This isn’t insomnia in the traditional sense; it’s unrefreshing sleep.
2. Adrenal load from years of “just pushing through”
Most women I see in their 40s have been carrying significant demands for years — careers, children, households, ageing parents. The adrenal glands, which manage your stress hormones, have been working overtime. When ovarian hormone production starts to decline, the adrenals are also asked to pick up the slack. Something has to give.
3. Iron that’s “technically fine” but functionally low
Standard blood tests check serum iron and haemoglobin. But ferritin — the stored form of iron — can sit at the very low end of “normal” (say, 12–18 μg/L) and still cause significant fatigue. Many practitioners won’t flag this. If you haven’t had a specific ferritin check, ask for one.
4. Blood sugar swings you don’t notice
Declining oestrogen reduces insulin sensitivity. This means your blood sugar becomes more reactive — spiking after meals and then dropping sharply. That mid-afternoon wall? The brain fog after lunch? Often this is blood sugar crashing, not laziness.
5. The mental load doesn’t show up in blood tests
Cognitive fatigue is a real, physiological state — not weakness. Carrying the mental load of a household, managing anxious thoughts, or simply being emotionally responsible for everyone around you burns neurological resources. Your brain uses roughly 20% of your total energy. When it’s constantly “on,” that’s energy your body never gets to use for repair.
“Exhaustion in your 40s isn’t a character flaw or a sign that you’ve done something wrong. It’s your body asking — clearly and loudly — for something to change.”
A Traditional Chinese Medicine Perspective
In Chinese medicine, the pattern I most frequently see in women presenting with this kind of exhaustion is what we call Kidney Yin deficiency — sometimes combined with Liver Qi stagnation.
That might sound abstract, so here’s what it means in practice:
TCM perspective
In TCM theory, the Kidneys are considered the root of all vitality — they store your deepest reserves of energy, and they naturally decline from midlife onward. When Kidney Yin (the cooling, nourishing, restorative energy) becomes depleted, the body starts to run “hot and dry” — you feel wired but tired, wake in the night, feel warm in the evenings, and find it hard to wind down. The Liver, meanwhile, governs the smooth flow of energy through the body. When it becomes stagnant from stress, the result is irritability, tension, and a kind of stuck, frustrated exhaustion.
These patterns don’t mean something is irreversibly wrong. They’re simply a way of describing where the body needs support — and they guide which acupuncture points and, if needed, herbal formulas might be most helpful.
What Can Actually Help
The honest answer is: there is no single fix. But there are things that make a real difference — and they tend to work best when done together.
1. Check the things that are often missed
Before anything else, get your ferritin checked (not just iron), ask about free T3 and T4 alongside TSH, and consider a full hormone panel including oestradiol, progesterone, and DHEA-S. A good integrative GP or naturopath can help interpret these in context, rather than just flagging anything inside the reference range as “normal.”
2. Protect sleep quality, not just duration
Eight hours of shallow, disrupted sleep is not equivalent to seven hours of deep sleep. Prioritise a consistent sleep-wake time, keep the room cool (lower oestrogen means your thermoregulation is less stable), and consider magnesium glycinate in the evening, which supports both sleep quality and the nervous system.
3. Stabilise blood sugar through the day
Eating protein at breakfast — not just toast or fruit — has a surprisingly significant impact on energy stability through the day. Avoiding long gaps between meals, and including fat and protein with every meal, helps prevent the afternoon crash that so many women in their 40s describe.
4. Move, but not always hard
This is counterintuitive: high-intensity exercise every day may actually be making things worse if your cortisol is already elevated. The adrenals interpret hard training as stress. For many women in this phase, a mix of moderate walking, swimming or yoga — with one or two harder sessions per week — tends to restore energy rather than deplete it further.
5. Acupuncture for nervous system regulation and hormonal support
Acupuncture won’t replace sleep or fix a thyroid issue — and I always say that clearly to patients. What it can do, based on both clinical experience and a growing body of research, is support the body’s own regulatory systems. This includes helping to regulate the HPA axis (the system governing cortisol and stress response), supporting sleep quality, and addressing the specific TCM patterns of depletion that present in perimenopause.
In practice, most patients I treat for this kind of fatigue start with weekly sessions for four to six weeks, then move to fortnightly as we see improvement. Results are usually gradual — not a sudden switch — but by week three or four, most women report sleeping more deeply, waking less in the night, and finding the mid-afternoon crash less severe.
Frequently Asked Questions
How do I know if what I’m experiencing is perimenopause or just stress?
Often it’s both — and they feed each other. The clearest signs that perimenopause is a factor are changes to your cycle (shorter, longer, heavier, or irregular), sleep disruption that’s new for you, and a type of tiredness that doesn’t fully recover with rest. A hormone panel can give you useful information, though results should always be read alongside symptoms rather than in isolation.
Can acupuncture help if I’m not yet perimenopausal?
Yes. Fatigue in the 40s has multiple contributing factors, and many of them — adrenal load, poor sleep quality, nervous system dysregulation — respond well to acupuncture regardless of hormonal status. We always treat the whole picture, not just the hormones.
Is acupuncture covered by private health insurance in Australia?
Many private health funds in Australia do cover acupuncture under Extras cover, typically under the “natural therapies” or “traditional Chinese medicine” category. The rebate amount varies by fund and level of cover. It’s worth calling your fund directly to ask what’s included in your policy before you book.
How many sessions before I notice a difference?
Most patients notice some shift within three to five sessions, though this varies depending on how long the fatigue has been building and what else is going on. Acupuncture works cumulatively — each session builds on the last. We typically review progress at the six-week mark and adjust the treatment plan from there.
