Variations in Blood Pressure
Blood pressure is influenced by many factors and can change from moment to moment. Normally,
blood pressure is lowest during sleeping periods and rises during the day. The graph below
epresents variations in blood pressure shown over a day with measurements taken every 5 minutes.
The dotted line represents the sleep
period. The rise in blood pressure at 1
p.m. (A in the graph) corresponds to a
stressful occurrence and at 7 p.m. (B in
the graph) a period of exercise.

Why Monitor Your Blood Pressure at Home?
A visit to a physician’s office can be a stressful situation for a patient. And, anxiety is a known factor
in raising blood pressure. This temporary occurrence of elevated blood pressure at the physician’s
office is commonly referred to as “white coat syndrome”.
Whether or not you experience “white coat syndrome”, home blood pressure monitoring provides
you with the opportunity to supplement your physician’s office measurements. These home
readings, when taken over a period of time, can show an accurate indication of change.
Furthermore, your records can assist your physician in evaluating your health and in making
important decisions in the diagnosis and treatment of your condition. Because of this, it is
important to take consistent, daily measurements of your blood pressure.
The variations in your individual readings should only be interpreted by your physician or a trained
health care professional.
WHO Blood Pressure Classifications
Standards for assessment of high or low blood pressure have been established by the World Health
Organization (WHO) as shown on the following chart:
This chart is only a general guideline. Contact your physician or trained healthcare professional to
determine your NORMAL blood pressure.
