What you should know about blood pressureWhat you should know about blood pressure

The circulatory system has the important task of supplying all
organs and tissues in the body with sucient blood, and of re-
moving metabolites. The heart does this by contracting and ex-
panding at a regular rhythm of around 60-80 times per minute.
The pressure created by the blood ow on the artery walls when
your heart contracts is referred to as systole. The pressure in
the subsequent relaxation phase when the heart lls with blood
again is referred to as diastole. In your daily measurement, you
will measure both values.
Our blood pressure responds to internal and external inuenc-
es like a sensitive measuring instrument. Aected by mental,
physical and environmental inuences, it varies all the time and
never remains constant.
Reasons for uctuating blood pressure values can be: moving,
speaking, eating, consuming alcohol or nicotine, nervousness,
inner tension, emotions, room temperature, recent urination or
bowel movements, environmental inuences such as move-
ments and sounds, etc. Even changes in the weather and climate
can have an eect on your blood pressure.
This explains why values measured at the doctor are often high-
er than those you obtain at home in your usual environment.
Even the time of day has an eect 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.
1. The systolic and diastolic blood pressure value
2. Why you measure dierent values
3. Why should you measure blood pressure regularly?
One-o and irregular measurements therefore say little about
your actual blood pressure. A reliable assessment is only
possible when measurements are taken regularly. Discuss the
measured values with your doctor.
