What is blood pressure?

The blood pressure is the pressure the blood is exerting on the walls of the
arteries. The blood pressure in the arteries is subject to continuous variation
during a heart cycle. The highest pressure within this cycle is called 'systolic
pressure' (SYS), the lowest pressure is called 'diastolic pressure' (DIA). With
these two blood pressure values, a doctor can determine a patient's blood
pressure. Your blood pressure may be influenced by many different factors
as physical effort, anxiety or the time of the day etc. Generally, blood pres-
sure is low in the morning and raises in the afternoon towards the evening.
In summer, blood pressure is lower than in winter.
Why is it a good thing to measure blood pressure at
home
Having one's blood pressure measured by a doctor in a hospital or clinic
environment tends to stimulate nervousness in a patient and may lead to a
higher blood pressure. Blood pressure varies in accordance with a variety of
conditions and so judgment is not always possible on the basis of a single
measurement. Blood pressure measured first thing in the morning after get-
ting up, before eating, and keeping still, is known as the fundamental blood
pressure. In practice it is rather difficult to record the fundamental blood
pressure but measurement at home in the right environment aids this.
