Blood pressure is a measurement of the force of blood owing
against the walls of the arteries. Arterial blood pressure is
constantly changing during the course of the cardiac cycle. The
highest pressure in the cycle is called the systolic blood pressure,
the lowest is the diastolic blood pressure. Both pressure readings,
the systolic and the diastolic are necessary to enable a physician
to evaluate the status of a patient's blood pressure. Many factors
such as physical activity, anxiety or the time of day, can inuence
your blood pressure. Blood pressure is typically low in the
morning and increases from the afternoon to the evening. It is on
average lower in the summer and higher in the winter.
Medical practitioners generally recommend the “Rule of 3”, where
you are encouraged to take your blood pressure three times in a
row (at 1 minute interval), three times a day for three days. After
three days you can average all the results and this will give you
an accurate idea of what your blood pressure really is.
