Here's the article from earlier last year: <a href="https://www.colorado.edu/today/2021/06/29/5-minute-breathing-workout-lowers-blood-pressure-much-exercise-drugs" rel="nofollow">https://www.colorado.edu/today/2021/06/29/5-minute-breathing...</a>
I'd refer to this as a "submarine article" or whatever, but that would mean that there was an actual link to the product somewhere in TFA...which if there is, I didn't find it:<p><a href="https://www.powerbreathe.com" rel="nofollow">https://www.powerbreathe.com</a><p>US$40 and up. My wife has high blood pressure, but I don't. However, as a distance runner, this part interested me, so perhaps I'll get one or two:<p><i>"Craighead, whose personal marathon best is 2 hours, 21 minutes, says he has incorporated IMST as part of his own training."</i>
The breath training they are referring to is breathing through a device with flow resistance, making it harder to pull in the air. (30 times per day for six weeks).<p>Strengthening the breathing muscles is what improves the blood pressure, according to the article.
