The short version
Why nights get harder in midlife
A hot flash is a sudden rush of heat to the face, neck and chest that lasts from a few seconds to several minutes. When one comes during sleep and leaves you damp with sweat, it is usually called a night sweat. ACOG also lists the sleep changes that come with perimenopause: trouble falling asleep, and waking long before your usual time.
The order is not always what it seems. The National Institute on Aging notes research suggesting that waking may itself set off a hot flash. And the NHS puts the usual run of menopause symptoms at 7 to 9 years, sometimes longer, which is why it is worth getting the bedroom and the habits right rather than waiting it out.
Before your appointment
Two weeks of notes say more than a tired summary
The National Institute on Aging suggests noting what sets off your hot flashes and how much they bother you. Write down bedtime, wake time, each waking and whether a flash or a sweat came with it, and rate each symptom as mild, moderate or severe. A doctor can work with that.
- Bedtime, wake time and how many times you woke
- Each hot flash or night sweat, with the time and how bad it was
- Alcohol, caffeine and late meals on the evenings before
- Any new medicine, and the day you started it
How we work
Why you can check everything here
Sources you can open
Every health fact links to the page it came from: the NHS, the National Institute on Aging, ACOG, The Menopause Society, NICE, or a published study. If we cannot link it, we leave it out.
No treatment advice
We explain what the health services say and what to ask. Decisions about hormone therapy, medicines and supplements belong with your doctor, so we do not recommend any. Our editorial policy sets out the rest.
