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.
