2. INFORMATIONS
Heart contracts
(pressure increases)
Blood pressure
Blood pressure is the pressure inside the arteries. This pressure is exerted by the blood on the
artery walls, and is expressed in millimeters of mercury (mmHg).
When the heart contracts (systolic or maximum pressure): the pressure suddenly increases in
the arteries, this is the first number that your physician gives you when measuring your blood
pressure. It is normally under 14 (140 mmHg).
When the heart relaxes between beats, the pressure decreases (diastolic or minimum pressure):
This pressure corresponds to the second number your physician gives you when measuring
your blood pressure. It is generally between 5 and 9 (50 and 90 mmHg).
Both numbers provide important information about your health. The harder it is for the blood to
flow through the arteries, the higher these two numbers will be. If the blood pressure is persis-
tently above normal, this is called hypertension.
Blood pressure varies considerably throughout the day, and these variations are even more sig-
nificant in hypertensive subjects. It is lower in the morning and increases in the afternoon and
the evening. When sleeping, it decreases. Blood pressure is lower in summer than in winter, and it
rises noticeably with age. Blood pressure also increases during exercise, sex, pregnancy, stress, etc.
