Keep in mind that your blood pressure can vary naturally throughout the course of a day. Exercise or physical activity has a tendency to raise blood pressure, so refrain from taking a reading afterwards. Stress can influence blood pressure too. In fact, white coat hypertension is a phenomenon where the anxiety of visiting with a doctor can raise blood pressure where it wouldn’t be elevated otherwise.
Make sure that you are measuring your blood pressure on a regular basis and at the same time of day, controlling for as many confounding variables as possible. For these reasons, measuring your blood pressure first thing in the morning works well for some people. Also, because your blood pressure can vary, it’s important to obtain many readings to observe a trend or pattern.
The best way to check your blood pressure is manually through trained medical personnel. The accuracy of automated electronic blood pressure machines can vary depending on the quality of the device. Some machines may need occasional calibration or maintenance too. To determine the accuracy of your home device, take it with you the next time you go to the doctor and have a trained medical person measure your blood pressure manually and then compare it with your device.
