I've now taken my blood pressure around 29,000 times since 1998, or about 7 times per day.
During all of those numerous Blood Pressure readings, I have seldom taken my blood pressure more than once at a time. In rare instances, where I KNOW that the first reading was bonkers, I'll take it more than once, but I would separate the readings by at least 15 minutes.
I don't want successive compression of my artery
to distort my blood pressure readings; and I want to be very consistent with how I take my blood pressure so that I can have confidence and consistency in the readings.
I don't know why successive Blood Pressure readings are lower than the first reading, but I have a feeling that it has something to do with the compression of the artery and how fast the artery recovers from the initial compression.
I avoid the worry and fear of High Blood Pressure by taking positive steps, such as going on a very healthy diet, exercise, the most effective medication for my unique health problems, and avoiding the irritants that I have found to cause my blood pressure to go up.
Regards..... and best of luck and health!
