Interesting!

I bet it is similar in the basic idea of getting the gunk out. How it gets out is likely best left up to experts.

What I noted was that feeling when one takes a deep breath did not extend down as far as it normally would. And repeated ones would dislodge some gunk, and often I would gak that up.

When I inverted, I had someone lightly pummel my back, open heel of the hand, just thump, thump, thadathump! Just a rapid rhythm while I took my lungs to their extremes, full inhale, full exhale, then cough and gak it out. And I used a cycle.

Get rested, feeling good, then invert, work the process and when something shakes loose, there is a lot of coughing, and one can't really do that upside down without getting a major league headache, so I had my spotter rotate me head up and I would work the gunk, until it came out, or I reached a steady state where it's just not happening. Rest, repeat.

Took about an hour.

And the aftermath was a few days of sudden gakking stuff up too. It's like everything got shook loose, and often hunks of tar and other mucus would come up and out. Other times it would just be a fit of coughing and then nothing.

What I did notice near immediately after doing all this was a deep breath triggered that feeling much lower. There were areas doing air exchange without so much crap in the way.

Combustible cigarettes near immediately inflame lung tissue, blood pressure goes up and a whole lot of other things happen. Over time, our response to all that becomes more aggrevated and our ability to recover is reduced due to wear and tear with no effective rest. Like say someone gets too much smoke during some fire or other.

It's bad, but when they are away from all that, they are getting normal air and the body processes can do what they do and they heal. Some damage is done of course, and the healing is less than perfect, but the outcome is often good, unless someone crosses some line or other, like near death type crossing.

After I quit, I noticed improvements in a week. And sometimes little regressions, like after intense exercise. Coughing up chunks of this and that got me to thinking the body is probably responding in those areas and maybe that strain on it all inhibits the healing that would otherwise happen.

In the end, all I know is an hour spent working the problem got a bunch of crap out of my lungs that really didn't need to be there. Perhaps the body would absorb it, or it ends up coming out over time, or I think the more likely scenario is it's just there and the body deals with it.

Nothing hurt, and there was no blood. It honestly felt like clearing out like what might happen after a particularly bad flu or pneumonia.

It has been years now, and I still feel improvement every summer. Some of that is just our normal healing and re-invigoration that happens when one gets outdoors for an extended time. And that's most of it. But, each year the peak lasts longer. I get through more of a less active winter before feeling like I really need some sun, good air, and exercise.

Speaking of which... There is a lot of rain where I live and our outings are delayed. Mrs and I both feel it big time! Hoping for more of a summer to happen soon, or we might just have to take a bigger trip and go somewhere we can get after all this anyway.

We just love our spot. Have been going since we were married.
