I don’t know about helping high blood pressure but these excersises really do work for asthma. About 20 years ago I was in the hospital for a massive asthma attack, doctors couldn’t seem to calm it. They finally sat by my bed for over two hours injecting some crap into my veins and that finally got rid of it. But the woman in the next bed suggested I take shallower breaths and exhale longer. Wow, couldn’t believe the difference. Haven’t had an attack since, unless you count the three times I had aspirin related attacks. Her suggestion wasn’t as scientific as this report, but I think the basics were the same.
Ok in his book “the bulletproof mind” Col Grossman mentioned a breathing technique that was close to what I was taught when I was fighting.
Breathe in thru the nose and count 1 2 3 4
Hold, preferably in the diaphram area 1 2 3 4
Then out thru the mouth 1 2 3 4
Repeat the cycle 3 times.
It really helps calm you down when stressed and trying to do something that takes finer motor skills.
Is it similar to your asthma breathing style?
I am curious.
Wow, that is great.
Funny, we are always told to take deeper breaths. Hmm . . .
