If you’re waking at night, struggling to fall asleep, or feeling wired but exhausted in the evening, you’re not alone.
Sleep problems are one of the most common symptoms of perimenopause, and they are caused by hormonal changes in the brain — not by bad sleep habits.
Many women don’t want, or can’t take, hormone replacement therapy — so the question becomes:
What actually works without hormones?

Why Perimenopause Breaks Sleep
Perimenopause causes:
-
Fluctuating oestrogen
-
Falling progesterone
-
Rising cortisol
-
Reduced melatonin
Oestrogen normally supports:
-
Serotonin (which converts to melatonin)
-
Body temperature regulation
-
Blood flow to the brain
Progesterone normally:
-
Activates GABA (the brain’s calming neurotransmitter)
-
Converts into natural sedative compounds
When these fall and fluctuate, the nervous system becomes over-alert at night, causing:
-
Difficulty falling asleep
-
Night waking
-
Racing thoughts
-
Anxiety
-
Shallow sleep
This is why sleeping pills don’t solve the problem — the issue is neuro-hormonal.
What “Non-Hormonal” Support Actually Means
Non-hormonal support doesn’t mean ignoring hormones.
It means supporting:
-
Neurotransmitters
-
Blood flow to the brain
-
Stress hormones
-
Oestrogen signalling
-
Gut-hormone recycling
This is exactly what PERI was designed to do.

How PERI Supports Perimenopause Sleep Without Hormones
🧠 Neurotransmitter support
L-Tryptophan
Builds serotonin, which converts into melatonin for sleep.
Inositol
Calms racing thoughts and nervous system overactivity.
L-Glutamine & L-Glutamic Acid
Support stable brain energy and nerve signalling.
🌸 Oestrogen-buffering plant compounds
Red Clover & Soy Isoflavones
Provide gentle phytoestrogens that smooth oestrogen drops that trigger night waking.
Dong Quai & Maca Root
Support hormonal signalling and cycle stability.
Resveratrol
Supports oestrogen receptor function in the brain.
🧠 Blood flow & brain oxygen
Ginkgo biloba
Improves cerebral circulation for deeper, more restorative sleep.
L-Arginine
Improves nitric oxide and blood flow.
🌿 Stress and cortisol control
Siberian Ginseng
Helps prevent cortisol surges that keep you awake.
🦠 Gut-hormone support
Lactobacillus acidophilus
Supports healthy oestrogen recycling so levels don’t crash overnight.
🌿 Foundational plant nutrients
Irish Sea Moss & Alfalfa
Support thyroid, minerals and metabolic balance that influence sleep.

FAQs
Can you manage perimenopause sleep problems without HRT?
Yes. Supporting neurotransmitters, oestrogen signalling and stress hormones can significantly improve sleep.
Why do I wake up anxious at night?
Fluctuating oestrogen increases cortisol and reduces calming brain chemicals.
Are herbal and nutritional approaches effective?
When targeted to the correct pathways, they can be very effective.
Is Arbor PERI suitable for non-hormonal sleep support?
Yes. PERI was designed to support hormone-brain balance without adding synthetic hormones.
Key Takeaway
Perimenopause sleep problems are not caused by poor habits.
They are caused by:
-
Oestrogen fluctuation
-
Progesterone loss
-
Cortisol spikes
-
Neurotransmitter imbalance
Non-hormonal, targeted support like Arbor PERI helps restore balance so sleep can return naturally.
