I know I'm probably known more for jokes and comments to other peoples posts. But I do take my Asthma and all thoracic issues very seriously.
I will one day post what I find most efficacious in terms of activity, lifestyle and exercise,
But as a taster two things. Firstly, I used to teach Tai Chi, more especially the health giving side known as Chi Gong (healthy movement). I would commend -Tai Chi breathing as a simple and effective exercise. I can describe it if you are interested. Plenty on YouTube, some worth looking at. Secondly, I subscribe to a number of US medical sites. They tend to be less secretive closed user, more open in discussing R&D. Recommend this site Medical News Today email@example.com as one worth contacting if you are interested in the medical side-written by Scientists and Drs for their peers. I had no problems in getting their weekly news letter emailed. Piece today on COPD and diet. This time it comes with benefit of peer reviews.
