lower than those measured at the doctor's office.
Blood pressure can vary by as much as 30 to 50 mmHg depending on
whether you are nervous or relaxed.
Blood pressure fluctuations throughtout the day.
(Direct measuring method)
Provided by Dr. Osamu Tochikubo of the Second Internal Medicine,
the Faculty of Medicine at Yokohama Municipal University.
Blood pressure values measured at home are sometimes
25 to 30 mmHg lower than those measured at the doctor's
office. This is caused by the fact that you may be nervous
at the doctor's office, but are relaxed at home. It is
important to know your regular normal blood pressure
measured at home.

• Breathing • Exercise • Mental stress • Concern
• Environmental and/or temperature change • Eating
• Urination and bowel movement • Conversation • Taking bath
• Drinking alcohol • Smoking, etc.
Please understand that blood pressure fluctuates easily as shown above.
