De nitions and Classi cations of Blood Pressure Levels
Measure your blood pressure at the same time each
day.
* Your blood pressure changes all the time. This means that data
gathered over a long period has far more signi cance than data
from just one measurement. For this reason, you must measure your
blood pressure on a daily basis. Ideally, you should measure your
blood pressure at the same time each day, wherever possible.
