SYMPTOM · PERIMENOPAUSE
Night sweats
You wake up drenched, with sheets and pyjamas to change, sometimes several times a night: night sweats are the night-time version of hot flushes and one of the main causes of broken sleep in perimenopause.
Why it happens
Just like daytime hot flushes, night sweats come from an internal thermostat that has become more sensitive to small changes in temperature because of falling oestrogen. At night, that abrupt cooling reaction tends to wake you with a start.
What tends to trigger a night sweat
- A bedroom that's too warm or poorly ventilated.
- Alcohol or a heavy evening meal.
- A duvet or pyjamas that are too warm.
- Stress built up during the day.
In the moment
- Keep a change of clothes and a towel by the bed.
- Air the room quickly or use a fan.
- Breathe slowly so you can drift back to sleep more easily after waking.
Day to day
- Choose bedding and nightwear made from natural fibres, they breathe better.
- Keep the bedroom cool, ideally between 17 and 19°C.
- Cut back on alcohol in the evening if you notice it's linked to your episodes.

If several of these symptoms ring true, it's no coincidence.
Menopause isn't just about hot flushes. Symptoms can begin years before your last period and affect sleep, mood, energy, memory, weight and intimate health.

Brain fog
You search for words, reread the same sentence twice, lose the thread mid-conversation. Nothing to worry about: your brain is simply running slower, with less glucose to fuel it as oestrogen levels fall.
Sleep problems
Asleep in ten minutes yesterday, wide awake at 3 a.m. today, for no reason. Progesterone, which helped you switch off at night, is in shorter supply, and deep sleep takes the hit straight away.
Anxiety
Stress that spikes over an email, a meeting, running ten minutes late. Oestrogen affects serotonin: when it yo-yos, everything feels heavier to carry than before.
Joint pain
Knees that creak as you stand up, hands that feel stiff in the morning. Cartilage loses its best anti-inflammatory ally as oestrogen falls, and you feel as if you are rusting up all over.
Hot flushes
A wave of heat rising from the chest to the face, lasting one to five minutes. Deprived of oestrogen, the thermoregulatory neurons in the hypothalamus narrow the thermal neutral zone: a few tenths of a degree are enough.
Palpitations
Your heart suddenly races, with no effort and no reason. Oestrogen also influences the nervous system that sets your heart rhythm. Alarming in the moment, rarely serious.
Mood swings
You laugh, and thirty seconds later you could cry or tell everyone where to go. Hormones rise and fall faster than before, and your mood follows, without warning.
Weight gain
Your tummy rounds out even though nothing on your plate has changed. Oestrogen redirects fat storage towards the abdomen, and your metabolism runs a little slower than before.
Low libido
Desire takes longer to arrive, or barely arrives at all. Oestrogen and testosterone fall, and sensitivity with them. The desire is still there; it just takes longer to get going.
Vaginal dryness
A feeling of dryness, sometimes a little discomfort day to day. Tissues lose their natural moisture as oestrogen falls. It is a common symptom, and still too rarely talked about.
Irregular periods
One cycle shorter, another dragging on, a month skipped altogether. Ovulation becomes less regular as the ovaries slow down. It is often the very first sign of perimenopause.
Pain during sex
Discomfort, sometimes real pain, during or after sex. Tissues thin as oestrogen falls, and what never used to be a problem can become sensitive.
Dry skin
Skin that feels tight, marks more easily and seems to have lost some of its bounce. Collagen declines with oestrogen, by up to 30% in the first few years after menopause.
Chronic fatigue
Tiredness that will not lift, even after a good night. Broken sleep, falling hormones: your body runs less efficiently, and you feel it from morning to night.
Hair loss
More hair in your brush, a parting that seems to be widening. Oestrogen used to extend its growth phase. Without it, the cycle shortens and each strand gets finer.
