7. Some Useful Information about Blood Pressure
Why is it a Good Thing to measure Blood Pressure at Home?
Many factors such as physical activity,
anxiety, or the time of day, can
influence your blood pressure. A single
measurement may not be sufficient for
an accurate diagnosis. Thus it is best to
try and measure your blood pressure at
the same time each day, to get an
accurate indication of any changes in
blood pressure. Blood pressure is
typically low in the morning and
increases from afternoon to evening. It
is lower in the summer and higher in the winter.
