The circulatory system has the important task of supplying all
organs and tissues in the body with sufficient 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 flow on the artery walls when
your heart contracts is referred to as systole. The pressure in
the subsequent relaxation phase when the heart fills 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 influenc-
es like a sensitive measuring instrument. Affected by mental,
physical and environmental 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, emotions, room temperature, recent urination or
bowel movements, environmental influences such as move-
ments 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 high-
er than those you obtain at home in your usual environment.
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.
1. The systolic and diastolic blood pressure value
2. Why you measure different values
3. Why should you measure blood pressure regularly?
One-off 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.
