" Seriously, BP is probably the most important health statistic around.
I'd agree, but it's not something you'd want to measure
continuously because of the procedure you have to go through every time:
- sit up straight,
- arm extended flat on a table,
- feet square on the ground,
- breathe evenly,
- don't talk to anyone,
- don't think about anything "exciting" that would raise your bp.
- don't think of anything, at all.
- don't move
- and then...
- hold-that-pose for 15 secs.
And you're not done yet, you have to repeat the
entire procedure
two more times, with about a minute between each reading.
I measure my bp regularly, and having to do it weekly is a pain. I doubt very much that I'd want to do it more than once a day - so building miniaturized hardware into a device continuously on my wrist seems like overkill.
A separate iPhone-compatible bp cuff is about $100, accurate, reliable and easy.
[EDIT: Wow, I just realized that all of the above steps would fit in
perfectly with WatchOS 3's "Breathe" app. So is that what "Breathe" is
really for? To get us all used to sitting calmly for a few minutes while our BP is measured???]
