Hi! Just now i am in Sweden, and yesterday I met one of my relations with asthma. She showed me a gadget she has been given, a tube thing which she is encouraged to breathe through. It provides resistance, and the general idea is that it will help her strengthen her lungs, and also help her clear mucous from her lungs. She told me you can get these without prescription, but, unfortunately, none of the local pharmacies had them. I can't find them online either. I have never seen or heard of these in the UK. Does anyone else know of these? Instinctively they seem a good idea, like playing wind instruments, but that would drive me and neighbours mad. Does anyone have any knowledge of these kind of things?
