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.
