Hot flashes: what to record
Hot flashes are among the most commonly reported perimenopause symptoms, and among the most vaguely described. "I get hot flashes" tells a clinician almost nothing about frequency, severity, or trend — three things a dated record answers on its own.
Four fields do the work: when, how long, what preceded it, and how intense. Recorded the same way each time, a week of entries shows a pattern that no single flash can.
What to record
| Field | Example |
|---|---|
| Date and time | Tuesday, 2:15pm |
| Duration | About 3 minutes |
| What preceded it | Coffee after lunch; also just after a stressful call |
| Intensity | Moderate — noticeable to others |
| Context | Fourth this week, most in the afternoon |
A handful of words is enough per entry. The value is in the run of entries, not the depth of any one.
Hot flashes and night sweats are the same symptom
Both are vasomotor symptoms — the physiological event is the same, only the time of day differs. Recording them under one consistent label rather than as two separate things makes the total daily frequency visible, which is usually what a clinician asks about first. See sleep and night sweats for the overnight half of this.
What triggers get recorded, and why they're not conclusions
Common reported triggers include caffeine, alcohol, spicy food, heat, and stress — but triggers vary by person, and some people have none they can identify. Recording what preceded a flash is data, not a diagnosis of cause. Over several weeks a pattern may or may not emerge, and either result is useful to know.
What a clinician asks
- How often, and has that changed recently.
- How long each one lasts.
- How much it affects you — sleep, work, concentration, comfort in social situations.
- When they started, and whether that lines up with other changes (cycle, sleep, mood).
- Anything unusual — sudden severe onset, or symptoms that don't fit the usual pattern.
A dated log answers the first four before you're asked. What to take to your first appointment.
When to seek assessment sooner
Sudden, severe onset; flashes accompanied by an unexplained racing heartbeat outside the flash itself, unexplained weight change, or other symptoms that don't fit; or flashes that continue unusually long past the typical transition are reasons to raise it rather than wait. Your own health service publishes guidance on this, and it is worth reading rather than assuming.
This is general information, not medical advice. HormoneLog is a tracking tool, not a diagnostic or treatment device, and nothing here can tell you whether your symptoms are normal, what they mean, or what you should do about them. Those are conversations for a clinician who knows your history.

About HormoneLog
HormoneLog is an iOS app from Baker Ventures LLC for tracking perimenopause and menopause symptoms and keeping an HRT record: what you took, at what dose, from when, and what changed afterwards. It is built for the appointment, where "it has been bad lately" is worth far less than a dated record of frequency and severity. The app is in development.
HormoneLog is a record-keeping tool. It does not diagnose, does not score you, and makes no claim about symptom relief. The guides on this site link to NICE, the NHS, the Menopause Society and peer-reviewed sources, and say plainly where the evidence is thin. Everything here is free and needs no account.
Questions and answers
What should I record about a hot flash?
When it happened, roughly how long it lasted, what you were doing or feeling just before, and how intense it was on a scale you use the same way each time. Frequency across a week matters more than any single episode.
Are hot flashes and night sweats the same thing?
They are the same underlying vasomotor symptom, distinguished only by whether it happens while you're awake or asleep. Recording both under one consistent label makes the total pattern visible rather than splitting it in two.
How many hot flashes a day is normal?
There is no single normal. Frequency varies enormously between people and across the transition, which is exactly why a clinician wants your own baseline and how it changes, not a comparison to an average.
What would prompt a doctor to investigate further?
Flashes that started suddenly and severely, are accompanied by unexplained weight change or a racing heartbeat outside the flash itself, or persist well past the usual transition are reasons to mention it rather than assume. Your health service publishes guidance on when to seek assessment.
Can HormoneLog tell me if my hot flashes are perimenopause?
No. HormoneLog records what you log. Whether a symptom is caused by perimenopause is a clinical judgement based on your full history, made by someone qualified to make it.
