Today I spoke to a guy who is a keen supporter of a system called Wim Hof.He suggested that this method would be most beneficial to any person with COPD.I did do a google search of this and discovered that it seems it does improve the symptoms of COPD.I mention this for 2 reasons,one to bring this to your attention if you were unaware of this system and two to find out if any members here are aware of Wim Hof and have actually practised it,to discover if its claims to improve the lives of COPD patients.
