Interesting. I’m currently trying to lower blood pressure naturally and have found typical “in through nose, out through mouth” breathing exercises will drop mine a few points. Also, hand weights- 2 reps of 10 in each arm- will drop significantly. I have a lingering concern though that these are just ways to hack the test. In me, the drop has been temporary- by the afternoon it’s back up if that’s all I do. It is encouraging that this study seems to say there are long term benefits, but I still wonder if that’s because the treatments are allowing for better traditional cardio. In the video he kind of hints at that.
