Does anyone know of a map of the UK which indicates the areas where asthmatics are most likely to breathe more easily? I grew up in a city and my chest was very troublesome; I lived abroad for a year and my asthma disappeared; I moved to Kent 5 miles in land amidst farmers' fields and my chest is even more troublesome that when I lived in the middle of a city, although it might be because I'm in a valley. I'm now in a position where I am foot-loose and fancy-free and would happily relocate to anywhere in the UK if it meant easier breathing and fewer chest infections. However, no one seems willing to commit to saying which areas might be better. Moving house costs at least Â£10,000 and spending that amount of money to 'try out an area' would be too big a financial risk. If I knew of a few really likely areas, I wouldn't mind selling up and renting for 6 months to see how things went before buying. But where do I start? The UK's a big place! Any ideas would be welcome.
