Night sweats
Also called: waking up soaked, sweating through the sheets, nighttime hot flashes, kicking the covers off at 2 a.m.
Changing a shirt at two in the morning, or sleeping on a towel because it is easier than changing the sheets, is not something anyone warned you about. It is the same event as a daytime hot flash, and it costs more, because it takes the night with it. You do not have a fever and you are not doing anything wrong.
What is actually happening
Same mechanism as a hot flash: estrogen swings narrow the temperature range your brain will accept, a small rise reads as overheating, and your body dumps heat through the skin and sweats. At night it costs more for two reasons. Your core temperature is meant to drop for deep sleep, so the surge lands exactly where sleep is most fragile — and you cannot take a layer off or step outside, so you wake up instead.
How common this is
Night sweats and hot flashes are two forms of the same symptom, and around 80% of women have one or the other during the transition. For many women the night version is the one that does the damage, because of what it takes from sleep.

If you try one thing
A colder bedroom
The cheapest thing on this list, and for night sweats often the most effective.
The surge lands while you are asleep and cannot take a layer off, so the room has to do it for you. It is free, it works the same night, and it is the one thing here you can change before going to bed.
Set the room to 60–67°F (16–19°C) and use layers you can throw off one at a time rather than one heavy duvet. Cotton or linen, not synthetic.
Change the thermostat when you turn off the TV.
On a hard day: Kick one leg out from under the covers. That is a real thermoregulation trick, not a joke.

Asking about hormone therapy
The most effective treatment there is for hot flashes and night sweats. A conversation with a clinician, not something to start on your own.
Hot flashes usually settle within a few weeks of starting. Getting the appointment often takes longer than the treatment takes to work. · Depends on your insurance, your country and the form — ask what it will actually cost before you leave
What to say to a doctor
Say the word "night" out loud. Sweats that wake you tend to be taken more seriously than flashes during the day, and hormone therapy is the most effective option for both. Ask as well about anything that would explain sweating on its own — thyroid, some antidepressants and a few blood pressure medicines all do this.
