A lot of things can affect it including your body position, whether you’ve been physically active lately, had caffeine, smoked, or even had a bath.
Recommendations even say to sit in that position for 5 minutes before measuring.

There is no such thing as a Stupid Question!
Don't be embarrassed of your curiosity; everyone has questions that they may feel uncomfortable asking certain people, so this place gives you a nice area not to be judged about asking it. Everyone here is willing to help.
- ex. How do I change oil
- ex. How to tie shoes
- ex. Can you cry underwater?
Reminder that the rules for lemmy.ca still apply!
Thanks for reading all of this, even if you didn't read all of this, and your eye started somewhere else, have a watermelon slice 🍉.

MODERATORS
Yes, typically it runs a little higher when you stand.
Yes, standing vs sitting affects the reading.
In my case, I have a type of dysautonomia where either BP or HR change significantly when sitting vs standing vs laying down.
POTS?
Yes
We’re suspecting my stepdaughter might have it too; seeing a cardiologist in a few weeks
Good luck. Feel free to message me if you need to talk.
I believe the logic for taking blood pressure while sitting versus standing is that it typically produces a more reliable measurement, meaning that measurements taken today, tomorrow, and next week under the same conditions will be as similar as possible
It is an at rest measure ( supposed to be like 10 mins inactivity ) to check your pressure when doing no work. Standing is effort and if they take it just after you stood up woukd show an increase in numbers.
Ah, that's why they call you in from the waiting room after making you wait for at least a half hour point when your appointment was and immediately take it after you've just gotten up and then sat back down.
Maybe some docs do, mine always has me sit in the exam room waiting for doc
I believe it has to do with not obstructing the flow of blood returning from the lower extremities any more than necessary, to give a more accurate pressure reading at rest. If you’re walking or running, alternating muscle contraction helps to pump the blood upward, but if you’re just standing, the general muscle engagement to keep you standing can slow it. But I could be wrong about this.
