Why Am I Getting Hot Flushes and Night Sweats in Menopause?

Jan 31, 2026

If you suddenly feel waves of heat, drenching sweats, flushing in your face and chest, or wake up soaked at night, you are not ill — you are in menopause.

Hot flushes and night sweats are caused by low and unstable oestrogen, not by anxiety, weight or temperature.

What Actually Causes Hot Flushes?

Oestrogen plays a critical role in controlling the brain’s temperature centre (the hypothalamus).

When oestrogen drops:

The brain becomes hypersensitive to small temperature changes
Blood vessels suddenly widen
Sweat glands switch on
The body releases adrenaline

This creates the classic:

Sudden heat
Red face
Palpitations
Drenching sweats
Chills afterwards

This is not random — it is a faulty temperature signal caused by oestrogen loss.

Why They Often Get Worse at Night

At night:

Core body temperature naturally rises
Cortisol changes
Melatonin falls
Oestrogen is at its lowest

This makes hot flushes much more likely to trigger, causing:

Night sweats
Repeated waking
Soaked bedding
Exhaustion

FAQs

Are hot flushes caused by low oestrogen?
Yes. Oestrogen loss disrupts the brain’s temperature control centre.

Why do I sweat so much in menopause?
The nervous system becomes hypersensitive due to hormone changes.

Can supplements help hot flushes?
Targeted plant compounds and nervous-system support can significantly reduce frequency and severity.

Is Arbor MENO designed for hot flushes?
Yes. MENO contains herbs and phytoestrogens specifically selected for thermoregulation and menopausal symptoms.
