What you should know about blood pressure
D
1. Systolic and diastolic blood pressure values
2. Why you measure different values
3. Why should you measure blood pressure regularly?
The cardiovascular system has the important function of supplying all
organs and tissues in the body with sufficient amounts of blood and of
transporting metabolites. To do so, the heart contracts and expands at a
regular rate of about 60 to 80 times per minute. The pressure of the flow-
ing blood on the artery walls caused by the heart contracting is termed
systolic. The pressure in the ensuing relaxation phase, when the heart re-
fills with blood, is termed diastolic. During daily measurement you deter-
mine both values.
Even the time of day has an effect on your blood pressure. The values are
at their highest during the day. In the course of the afternoon and in the
evening, they drop slightly. They are low while you are sleeping, but rise
again relatively quickly once you get up.
Our blood pressure responds to internal and external influences like a
sensitive measuring instrument. Affected by mental, physical and envi-
ronmental influences, it varies all the time and never remains constant.
Reasons for fluctuating blood pressure values can be: moving, speaking,
eating, consuming alcohol or nicotine, nervousness, inner tension, emo-
tions, room temperature, recent urination or bowel movements, environ-
mental influences such as movements and sounds, etc. Even changes in
the weather and climate can have an effect on your blood pressure. This
explains why values measured at the doctor are often higher than those
you obtain at home in your usual environment.
One-off and irregular measurements therefore say little about your actual
blood pressure. A reliable assessment is only possible when measure-
ments are taken regularly. Discuss the measured values with your doctor.
