BP control is important for everyone, regardless of what illness or defect they are living with. One thing I know for sure, losing weight is the best way to get it down, in most cases. Salt is something I am not convinced is a problem, unless one is really overdoing it. Seems like a scapegoat in many cases.
I agree with the stress part, but then, even when I know I am stressed, as in a job interview, or when I look at the future and see nothing but darkness, yet under those conditions, I take my BP and its quite good, so I am not sure what to make of that.
Some time ago, my doctor wanted me to take a anti depressant, and he warned me that for a week or so, I might have panic attacks, but they would pass. I got the pills, and didn’t take them. Who wants a panic attack? I never had one, but it doesn’t sound like fun. Still, I had other problems so I took them for a few days and my doctor was right. Now I know what a panic attack is, and after it was over, I flushed the pills down the toilet. As I lay on the bed thinking death was near, I managed to check my BP, and it was just fine, even tho I would have thought it to be 250/150 based on how I felt.
Another long post… BP control matters no matter what. The question to ask would be, how low can you go before you have other issues? If I meditate for fifteen minutes just before bedtime, I can read my BP in the range of 80’s/50s compared to a more usual 120/65. My diastolic seldom rises with stress and anxiety. The systolic does climb when I am active, or feeling pressure.
