Thank you for sharing this and elaborating on what I've seen firsthand. Another thing we've noticed is that an increase in VO 2 Max, which does take quite a bit of time to change, makes a major difference.
Altitude is another factor, due to dry and colder air and lower oxygen -- a double whammy for asthma.
