Caffeine can temporarily affect blood pressure in some people.
Why it matters
For more comparable readings, follow clinical instructions and avoid measuring immediately after caffeine.
A practical routine
- Record recent caffeine when a reading is unusual.
- Keep timing consistent.
- Discuss personal sensitivity with your healthcare professional.
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.
