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). One's natural
blood pressure is represented by the fundamental pressure, which
is measured first thing in the morning while one is still at rest and
before eating.
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-filling 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 pronounced. Normally, blood pressure rises during
work or play and falls to its lowest levels during sleep.
About Blood Pressure
What is Hypertension and How is it Controlled?
Hypertension, an abnormally high arterial blood pressure, if left
unattended, can cause many health problems including stroke and
heart attack. Hypertension can be controlled by altering lifestyle,
avoiding stress, and with medication under a doctor's supervision.
To prevent hypertension or keep it under control:
U Do not smoke
U Exercise regularly
Li
Reduce salt and fat intake
U Have regular physical checkups
U Maintain proper weight
Why Measure Blood Pressure at Home?
Blood pressure measured at a clinic or doctor's office may
cause apprehension and can produce an elevated reading,
25 to 30 mmHg higher than that measured at home. Home
measurement reduces the effects of outside influences on blood
pressure readings, supplements the doctor's readings and
provides a more accurate, complete blood pressure history.
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 consideration and may affect these
figures. Consult with your physician for an accurate assessment-
