Blood pressure fluctuation and variation
Human blood pressure fluctuates and will vary 24 hours a day. Blood
pressure measurement can be affected by the measurement position,
posture, and physiologic condition as well as factors such as eating,
bathing, exercising, smoking, drinking alcohol, stress, mental tension,
breathing, conversation, movement, temperature or humidity change,
etc.
Obtaining reliable measurements
In order to obtain reliable measurements, follow recommendations
below:
1. Keep taking and recording blood pressure measurement consistently
at the same time every day to establish your blood pressure pattern.
2. Wait at least thirty minutes after eating, bathing, smoking, exercising,
or ingesting caffeine or alcohol before measurement.
3. Remove constricting clothing or ornaments from your arm and
ensure the range of cuff circumference is applicable to you.
4. Be seated and relax for at least five minutes in a quiet and
comfortable place prior to measurement.
5. Wait at least five minutes between measurements, so that your blood
vessels can return to the state they were in before measurement.
Rest between repeated measurements.
