Q

  Why is the blood pressure measured at home different from that 

measured by the physician or at a hospital?

A

  Your blood pressure may vary due to exercise, the ambient temperature 

or your mental state. When you have a physician or nurse measure your 
blood pressure, the pressure value is likely to be 10 to 20 mmHg higher 
than usual due to anxiety and/or stress. Knowing what affects your blood 
pressure helps you to better monitor your health.

Q

  Why does the blood pressure obtained vary with measurement?

A

  Our blood pressure is adjusted by automatic nerve function. Blood 

pressure differs with every heart beat. We are likely to think that our 
blood pressure is constant, but it varies if you take measurements 
in repetition. Blood pressure is susceptible to the time of day, such 
as morning and afternoon, season and atmospheric temperature. In 
addition, blood pressure is easily affected by mental stress or emotional 
ups and downs. It tends to increase when you feel tension or decrease 
when you are relaxed.

Q

  What is the benefi t of measuring my blood pressure at home?

A

  Blood pressure measurements taken at home give reliable data as they 

can be taken when you are in a stable and relaxed condition. Physicians 
place considerable importance on blood pressure measurements taken 
at home. You should measure your blood pressure at the same time 
each day and record the variations in your blood pressure.

Always consult your physician for an interpretation of your 
blood pressure readings and to determine the proper 
treatment.
