Sleep diary with blood pressure: what to write side by side
Free printable blood pressure log (PDF)
A sleep diary with blood pressure is a side-by-side record: how long the night was, and what the cuff said after you woke. Clinicians sometimes ask for both because the two are easy to forget separately. Blood Snap can hold them on one phone. It will not tell you that one caused the other.
This is a wellness diary, not a medical device and not a sleep study. You take blood pressure with your own monitor and confirm the numbers. You enter sleep as hours and minutes, or you show a tracker duration from Apple Health or Health Connect. The writing guide below is about what to capture, not about what the numbers "mean."
What to write for the night
In More Health → Sleep log, tap Add sleep. Two fields matter:
- Which morning you woke — that date is the day the night belongs to. You can pick any morning in the past year through today.
- Time asleep — hours and minutes, more than zero and at most 24 hours. This is duration, not the clock time you got into bed and not a sleep-stage breakdown.
If you only remember "about six and a half hours," enter 6 hours and 30 minutes and stay consistent about how you estimate. A diary that uses the same method every morning is easier to read than a mix of exact watch times and wild guesses. If a tracker already recorded the night, Home shows the tracker value instead of the manual one. Keep the manual entry for gaps, not as a second copy you expect the dashboard to prefer.
The Sleep log does not have a box for caffeine, alcohol, or a late meal. If your clinician asked you to remember those, keep them in whatever note you already use for the visit. Do not expect the sleep chart to store them. A named custom reminder can still nudge you to sit for the cuff; it will not fill in the night.
What to write for the morning reading
After you are up, take blood pressure the way you were taught, then log it before the number leaves the monitor screen. The home diary wants the reading you confirmed:
- Date and time of the reading.
- Systolic, diastolic, and pulse.
- The same unit and the same routine from day to day.
Type the digits, speak them, or snap the monitor and confirm before save. The steps are the same as in how to log blood pressure in a home diary. A sleep entry does not pre-fill the cuff, and a cuff entry does not pre-fill sleep.
A side-by-side page you can copy by hand
Use this layout when you want one sheet for a visit. The values are examples of format only.
| Wake morning | Time asleep | Morning blood pressure |
|---|---|---|
| Tue 4 Nov | 6h 20m | 07:40 · 132/84 · pulse 74 |
| Wed 5 Nov | 7h 45m | 07:35 · 126/80 · pulse 68 |
| Thu 6 Nov | 5h 50m | 08:10 · 136/88 · pulse 76 |
In the app, the left column is the Sleep log (or the Home sleep card). The right column is the blood pressure entry in History. They share the calendar day when you log sleep against the morning you woke and take the cuff that same morning. They are not one database row.
How Blood Snap shows the pair
- Home — blood pressure on its card; sleep on its card if Show sleep on dashboard is on. Tracker sleep wins over a manual duration for that day.
- Sleep log → Analytics — manual nights only, for 3, 7, or 30 days: entries, average, longest, shortest, total time, and hours asleep per night.
- Insights — blood pressure over 3, 7, or 30 days. Resting heart rate can appear with it when that metric is on. Sleep duration is not drawn on the blood pressure chart.
- History — blood pressure rows, with a sleep figure for the day when the sleep metric is enabled.
Steps and resting heart rate can join that Home view. They are covered with sleep in steps, sleep, and resting heart rate alongside blood pressure. Weight is a third morning number for some people; keep it in the weight and blood pressure log rather than inside the sleep row.
Questions to take to your clinician
The diary gives you dates. It does not give you the answer. Useful questions are specific:
- "Here are 14 mornings of cuff readings and the hours asleep I wrote down. Do you want me to keep both?"
- "I do not wear a watch. Is a manual duration enough, or do you want a tracker?"
- "Should a very short night change when I take my reading, or do I keep the same seated routine?"
Do not stop a medicine, add a sleep drug, or treat a single high reading from this table. If a reading comes with symptoms your clinician told you are urgent, follow that plan.
What side-by-side logging cannot decide
- It cannot prove that sleep changed your blood pressure.
- It cannot set a personal sleep target. Public pages often mention roughly seven or more hours for many adults. That is general background, not a Blood Snap goal and not your prescription.
- It cannot screen for sleep apnea or measure blood pressure while you sleep.
- Pro export still produces separate files: manual sleep from Sleep log, blood pressure from History.
Write sleep and blood pressure side by side in Blood Snap. Log hours asleep for the morning you woke, and log the cuff reading you confirmed. The diary keeps both. Your clinician interprets them. Not a medical device and not a diagnosis.
Educational information with public guideline citations. Not medical advice and not a diagnosis. Blood Snap is a personal wellness diary — not a medical device, blood pressure machine, glucometer, or CGM. Always follow your clinician's advice.
