What Is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of
the arteries. Systolic pressure occurs when the heart contracts;
diastolic pressure occurs when the heart expands. Blood pressure
is measured in millimeters of mercury (mmHg).
What Affects Blood Pressure?
Blood pressure is affected by many factors: age, weight, time of
day, activity level, climate, altitude and season. Certain activities
can significantly alter blood pressure. Walking can raise systolic
pressure by 12 mmHg and diastolic pressure by 5.5 mmHg.
Sleeping can decrease systolic blood pressure by as much as 10
mmHg. Taking your blood pressure repeatedly without waiting an
interval of 5 to 10 minutes between readings, or without raising
your arm to allow blood to flow back to the heart, can also affect it.
In addition to these factors, diet beverages containing caffeine or
alcohol, certain medications, emotional stress and even tight-
fitting clothes can make a difference in the readings.
What Causes Variations In Blood Pressure?
An individual’s blood pressure varies greatly from day to day and
season to season. In hypersensitive individuals, these variations are
even more pronounced. Normally, blood pressure rises during work
or play and falls to its lowest levels during sleep.
