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 tightfitting 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.
