What lifestyle consideration should be observed before blood pressure self-monitoring?

Before engaging in blood pressure self-monitoring, it is essential to rest for 5 minutes. This recommendation is based on the need for the body to be in a stable state before measurements are taken, as physical activity, stress, or recent consumption of food or stimulants can temporarily affect blood pressure readings. By allowing the body to rest, a more accurate and reliable measurement can be obtained, reflecting the individual's typical baseline blood pressure.

Other lifestyle factors, such as avoiding nicotine or caffeine, are generally advised when monitoring blood pressure, but the most crucial step is ensuring a period of rest prior to taking the reading. This resting period helps to minimize variability in blood pressure due to immediate physiological changes associated with activity or consumption. Standing while measuring can lead to an inaccurate reading due to postural changes affecting blood pressure, and eating a heavy meal may also cause fluctuations in blood pressure, further emphasizing the importance of resting before monitoring.
