About Blood Pressure
Blood Pressure Variations
An individual's blood pressure
varies greatly on a daily and
seasonal basis. It may vary by
30 to 50 mmHg due to various
conditions during the day. In
hypertensive individuals variations
are even more pronounced.
Normally, the blood pressure rises
while at work or play and falls to
its lowest levels during sleep. So,
do not be overly concerned by the
results of one measurement.
Take measurements at the same time every day using the procedure
described in this manual to get to know your normal blood pressure.
Regular readings give a more comprehensive blood pressure history.
Be sure to note the date and time when recording your blood pressure.
Consult your doctor to interpret your blood pressure data.
