ABOUT BLOOD PRESSURE

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
one's blood pressure. Walking will likely raise an individual's blood pressure.
Sleeping will likely decrease blood pressure. Not relaxing for several moments
before measurements can influence readings as well.
In addition to these factors, 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. For hypersensitive individuals, these variations are even more pro-
nounced. Normally, blood pressure rises during work or play and falls to its
lowest levels during sleep.

Assessing High Blood Pressure for Adults

The following standards for assessing high blood pressure (without regard to
age or gender) have been established as a guideline. Please note that other
risk factors (e.g. diabetes, obesity, smoking, etc.) need to be taken into con-
sideration and may affect these figures. Consult with your physician for an
accurate assessment.
