The not eating wouldn't be a problem but not moving................
Well to be accurate the instructions say:
'To take a measurement, you need to be relaxed and comfortably seated, under comfortable room temperature. No eating, smoking or exercising 30 minutes before taking a measurement.'
I just noticed that the instructions also say that the values that can be used as a guide to high blood pressure for measurements taken at home are:
Systolic Blood Pressure - Above 135 mmHg
Diastolic Blood Pressure - Above 85 mmHg
Since last August I have only had one systolic reading over 135 (136), mostly they are in the 120s or lower.
And I've only had 2 diastolic readings over 85 (86), Most have been between 66-81.
