Yes, very much so and management of it is very important for various reasons, even for people who don't have a blood pressure problem, let alone someone who does. I took the liberty of looking it up for you so I could give you a more informative answer, as I feel this subject warrants it and this is want I found:
"In a challenging situation the brain prepares the body for defensive action—the fight or flight response by releasing stress
hormones, namely, cortisone
. These hormones raise the blood pressure and the body prepares to react to the situation. With a concrete defensive action (fight response) the stress hormones in the blood get used up, entailing reduced stress effects and symptoms of anxiety
When we fail to counter a stress situation (flight response) the hormones and chemicals remain unreleased in the blood stream for a long period of time. It results in stress related physical symptoms such as tense muscles, unfocused anxiety, dizziness
and rapid heartbeats."
The site I got this from had a small article on it, which is where this bit of info came from. In case you are interested in reading it yourself to see it if applies to you or what you can learn, I'll list it below.
