Have your heard of this? Resperate [sic] -- not an endorsement, all I know is what's here, just ran into it browsing!
You don’t really need the gimmick black box to do that, although it probably will help some people manage their breathing rhythm. My brother can “manually” control his breathing to noticeably lower his BP on a subsequent test — not sure how long the effect lasts. I don’t seem to have the self control. But since my bp meds are $4 at Walmart I have no big incentive to invest in a method like that (my guess is many people use the device for a few days and then give it up).
Sounds interesting. I believe we are all going to have to turn to alternative methods, treatments, techniques, etc to keep ourselves healthy. Biofeedback is certainly a good way learn to lower you blood pressure...I don’t know what the limitations might be for someone with seriously blocked arteries, etc. I have used biofeedback and did lower my blood pressure with it. Consistently? Not necessarily, but if I had a worse problem, I’d be more inclined to stick with it.
And I’ve become a food saint. Dreadfully boring, but then, I’m in better shape than people 15 - 20 years younger. Not recommending any special diets...you have to experiment.
And then, of course, there’s regular attendance at the gym. Aaaaargh
Oh, yeah. I bought the Resperate machine a few years ago; for me it was way overpriced, and it didn’t work like they claimed. It was a tiresome and boring exercise machine, very expensive; but, hey, I’ve tried lots of things over the years. If just one thing works, it’ll be worth every penny I’ve wasted. Garlic capsules were the first thing I tried; if only it had been that simple!
