Tad put another post up about this, I'm just including here the BLF site search in the community where previous discussions about this have taken place for those interested in reading more about how the temperatures and weather conditions can affect people with lung conditions:
healthunlocked.com/search/p...
You may bring up alternative searches by using the words cold weather and your lungs (search box top right)
Also BLF's own pages on this:
blf.org.uk/Search?query=loo...
Take good care of those lungs one and all.
Any one not been on a PR course try to access one through your GP, this information and much more is usually covered on the course.
Best wishes BC
