Physical activity temporarily changes heart rate and circulation.
Why it matters
Unless given different instructions, allow time to recover and return to a calm resting state before a routine reading.
A practical routine
- Do not measure while breathing hard.
- Sit quietly with supported posture.
- Record recent exercise when comparing results.
Make the record useful
Use a correctly fitted upper-arm cuff, sit quietly with supported posture, and record paired readings when recommended. Add a short note when illness, pain, poor sleep, stress, exercise, meals, or medication timing adds context.
