New smart/ fitness watch BP rise

i never noticed but with the new watch I can be sitting (resting) and my BP can be at 60 to 70. but as soon as I get up, it jumps to 90 or higher. Also, when im driving, it goes up to 120s and i live in a rural area and no traffic.
I wear it at night and when I get up in the middle of the night and go to the bathroom, my BP goes from 50 to 90+

I was
sweeping the driveway and looked
at my watch and the BP was at 160

Question is why?

Is this a BP rise or HR rise? Either way this is perfectly normal

When you move your BP and pulse will increase it is normal.

Sorry, Not BP but pulse.

When I’m on the treadmill my pulse normally at 130 to 140. thats why my concern here. As not working so hard as sweeping a driveway to have it that high or just driving.

Driving is VERRY stressful and raises your HR. So is sweeping especially if you haven’t warmed up before you started. Nothing to worry about

thanks
