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 the lowest one usually at midnight. Typically, the value begins to increase at around 3:00 AM, 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 approxi-
mately the same time each day.
Too frequent measurements may cause injury due to blood flow interference, please always relax a mini-
mum 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.
