Have you considered if you change the way you breathe, your QOL could be increased not marginally but quite dramatically? Look away now if you are convinced the best path is to follow what the medics tell you and the rest is just mumbo jumbo.
Book review:
I have just read the new instant best selling book Breath by James Nestor mrjamesnestor.com and have already acted on some points with early positive results. I have heard the point about improving breathing before but what makes this book so impressive is the convincing way it conveys the potential with clear explanations of issues, including those relevant to AFers.
Essentially, it is all about changing habits to breathe through your nose only, less breaths per minute and the importance of chewing whatever your age. Many of us evidently use our mouths too much & take too many breaths due to stress levels. I made some brief notes when reading which I hope are accurate:
Overbreathing is the reason why our body can't deal with many chronic & other issues & how it depletes important elements e.g. Magnesium & Potassium Mouthbreathing may be causing sleep apnea & too many bathroom visits (clearly explained why). He goes on to provide the best description of the Parasympathetic & Sympathetic systems I have read & how left & right nostril breathing affects these; left connected with parasympathetic before meals can also improve digestion. Nasal breathing releases through the sinuses a huge boost of nitric oxide (not the case through your mouth), which in turn delivers more oxygen to cells and increases circulation. Exhaling properly causes you to loose more weight; of 10lbs lost 8.5 comes from the lungs and 1.5 from sweat/urine.
I hope the above gives you some idea about this book. If just half the suggestions work that will be a huge result for me and I suspect many other AFers.
Caveats: Please take care and consult your doctor first if you plan to try any of the author's suggestions and understand I am not endorsing them. It also occurs to me if he is right on most of the issues one needs to take care when changing breathing habits, select only those your doctor thinks are safe/appropriate and implement them slowly over months as powerful changes overdone in the short term may have detrimental effects.
