Hi leslie757, and thanks for your post. I see my colleague, John, has already provided a good response for your concern.
Since you are not new to asthma, you are probably aware that asthma affects all patients differently. As well, triggers can vary widely from patient to patient.
Having said that, for some people dry air can provide them with great comfort (for their breathing), while for others, the very same conditions may act as a trigger.
Although you may be on target (for yourself), that the conditions you identified provided a challenge for your condition, it also may be associated (and therefore coincidental), with other triggers that may have affected you on these days.
Naturally, you are the one who knows yourself and your condition best. And so, you may be 'spot on' with your analysis as to what happened to you. Again, you may want to discuss this further with your physician.
We're glad to have you as a (new) member in our asthma.net community. Please know that you are always welcome here!
All the best,
Leon (site moderator asthma.net)
