When is the best time to measure blood pressure for the most accurate reading?
My blood pressure is unstable, fluctuating between high and low, so I need to measure it regularly. I really want to know, when is the most accurate time to measure blood pressure?
Doctor's answer (1)
The accuracy of blood pressure measurement is influenced by the timing of the measurement. The following are time points that can provide the most accurate blood pressure readings:
1. After waking up in the morning: When you first wake up in the morning, the body has not yet experienced daily activities or eating, and blood pressure measurements taken at this time are relatively stable. After a night's rest, blood pressure levels are closer to baseline values and can provide a more accurate reflection.
2. During a resting state: At least 5 minutes of seated rest is recommended before taking a measurement, and measurements should be avoided immediately after vigorous activity or emotional fluctuations. Blood pressure readings are more accurate when the body is relaxed. Smoking and intake of stimulant foods should also be avoided prior to measurement, as these factors may affect blood pressure levels.
3. Consistent measurement times: Measuring blood pressure at the same time each day helps track trends in blood pressure changes, making it easier for doctors to assess whether abnormalities exist. It is recommended to take measurements once in the morning and once in the evening.
If measurement results are unstable or abnormal, you should consult a doctor.
