That sudden wave of heat, flushed face or waking up drenched at night are called vasomotor symptoms — the most common signs of perimenopause and menopause. They happen as fluctuating oestrogen affects the brain's temperature control. There are real options that may help, from lifestyle to herbal support to medical care.

What causes a hot flush?

Your brain has an internal thermostat in the hypothalamus. During perimenopause, shifting oestrogen makes that thermostat more sensitive, narrowing the comfortable temperature zone. Picture a thermostat that used to tolerate a wide range suddenly overreacting to a tiny change — it triggers the body to dump heat fast through flushing and sweating. At night, the same process wakes you drenched, which is why sleep so often falls apart in this stage of life.

Why do they vary so much between women?

Frequency and intensity differ enormously. Some women barely notice them; others have many a day for years. Triggers like heat, spicy food, alcohol, caffeine and stress can set them off, and Singapore's climate can make them feel worse. Because the experience is so individual, it's worth tracking your own patterns rather than assuming yours will match anyone else's.

What does the evidence say about herbal support?

Herbal options such as black cohosh and phytoestrogens are popular, and the evidence is genuinely mixed. Some guidance and studies suggest certain extracts may modestly help hot flushes and night sweats, while a large Cochrane review found insufficient evidence overall. In short: research suggests they may help some women, but they're not guaranteed and results vary. A botanical blend like Herbal Harmony: Meno Rebalance is designed as gentle support to try alongside lifestyle steps — not a replacement for medical treatment.

What else can ease hot flushes and night sweats?

Practical habits genuinely help. Dress in light layers, keep your bedroom cool, and use breathable bedding. Notice and reduce personal triggers such as alcohol, caffeine and spicy food. Regular movement, stress-reduction techniques and steady sleep routines can all lower the load. And importantly, talk to your doctor: for many women, menopause hormone therapy is a safe and effective option, and there are non-hormonal prescription options too. Supplements are one tool among several, not the whole toolbox.
