IMPORTANT INFORMATION
NORMAL BLOOD PRESSURE FLUCTUATION
All physical activity, excitement, stress, eating, drinking, smoking, body posture and many
other activities or factors (including taking a blood pressure measurement) will influence blood
pressure value. Because of this, it is mostly unusual to obtain identical multiple blood pressure
readings.
Blood pressure fluctuates continually ----- day and night. The highest value usually appears in
the daytime and lowest one usually at midnight. Typically, the value begins to increase at
around 3:00AM, and reaches to highest level in the daytime while most people are awake and
active.
Considering the above information, it is recommended that you measure your blood pressure
at approximately the same time each day.
Too frequent measurements may cause injury due to blood flow interference, please always
relax a minimum of 1 to 1.5 minutes between measurements to allow the blood circulation in
your arm to recover. It is rare that you obtain identical blood pressure readings each time.
