Blood pressure variations during the day
August 27, 2008 by Andy · 2 Comments
In this first of many blood pressure experiments, I used a home blood pressure monitor (upper arm cuff), to measure my blood pressure during my waking day.
The readings were not taken at specific intervals, and I have made no attempt to show on this graph when I ate food, did exercise, drank coffee, or anything else that might affect blood pressure. The whole point of this experiment was just to see how my blood pressure varied throughout the day.
Here are my results:

Average Blood pressure over the day: 129/82
Here is the chart of this data:
The fluctuations were not as big as I anticipated, but one thing I have noticed is that my blood pressure does tend to reduce as the evening progresses.
We have to be careful to draw any conclusions from this blood pressure data, but clearly, there is some variation during the day.
I will be looking at specific influences in other experiments, and how they affect my blood pressure, so look out for those. They will be listed down the left of this page.
