I have come to reside in Northern Ireland after living for last 20 years in Denver, Colorado, a mile high altitude, where I was a very active person, I am wondering if coming from such a dry environment, a mile high to sea level in a much more humid environment could have any role in this adult onset of Asthma
I also was diagnosed with Asthma at a similar age, after getting a virus on holiday but I am now living in Oxfordshire which is damp, which doesn't help. Did you catch a bug first?
I don't get symptoms except when I'm ill really or sports. I should think the change of climate hasn't helped. Years ago a health visitor told me that changing counties let alone countries exposes you to new germs so that you catch everything going until your immune system gets used to the new location.
