1.5 Common Blood Pressure Questions and Answers
a) Why is my blood pressure reading always different?
Your blood pressure changes constantly. It is quite normal for blood pressure to fluctuate
significantly (50 mmHg to 60 mmHg) throughout the day. Blood pressure is normally lowest at night,
but increases during waking hours when the stress and activities of everyday life are highest.

b) Why is the doctor’s reading different from the reading taken at home?
Your blood pressure can vary due to the environment (temperature, nervous condition). When
measuring blood pressure at the doctor’s office, it is possible for blood pressure to increase due to
anxiety and tension, this is known as “White Coat Hypertension”.
