Let me just first state that I am not a medical doctor. The experiments I have carried out on this site were carried out to satisfy my own curiosity, as I do have scientific training. I do not recommend you try any of these yourself – consult your doctor if you have blood pressure problems.
My idea for these experiments was to look at various factors that have been reported as affecting blood pressure. For those of us with hypertension (high blood pressure), this type of information if very important.
When I started these experiments, my own blood pressure was around 140/100. Through carefully watching my diet, and increasing the level of exercise, my blood pressure dropped to normal levels. In fact, its not unusual for my blood pressure to be now be around 100/60.
For all of these experiments, I used a home blood pressure monitor, with the upper arm cuff. I did test the accuracy of this when I first started using it by comparing the readings with those taken by my doctor.
