Too low of BP can be dangerous…
When I was in the hospital after my heart attack, my blood pressure at one point dropped down into the 70s, Now that I’m home, I monitor it every day, A few times it dropped down into the upper 80s, which is too low. What I do is lay down try to elevate my legs above my heart and drink plenty of liquids and keep an eye on it to make sure it’s going up.
I tend to run with a low blood pressure normally that ranges around 117 but since I’m still recovering from my heart attack if my blood pressure is above 100 I’m happy
