How does a change in weather affect asthma?
I've been having some problems with my asthma the past few weeks and people keep telling me, "It's the change in the weather." So, I'm wondering, how can the change in weather affect my asthma? I don't live in a cold climate. I live in the south, where we have been transitioning from summer/fall/winter all in one.
Thanks.
Thanks.

The general thoughts are that it is due to changes in humidity (moisture in the air) and air pressure, not SO much due to temperature changes, although for an asthmatic going out into the cold air can certainly shock the lungs too. But that is usually temporary. Just HOW these changes in humidity and air pressure impact the airways, the mucus and the cells in the lungs is not very well understood, but there are likely small effects to activate certain cells that make your asthma symptoms worse.

answered Jan 06 at 04:34PMWe need to know more about your particular triggers to answer this well. You might look at the work of Arundel on how humidity effects nasal problems; and the triggers for asthma seem to be identified by the nasal immune system. Arundels work is on line at http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1474709/?tool=pubmed. See especially his graph on page 358. As he points out optimal humidity is in the 40% range. That range is not common in our comfortable heated and cooled environments. My experience with a nasal spray containing xylitol which compensates for our unhealthy environments is covered in my book, NO MORE ALLERGIES, ASTHMA OR SINUS INFECTIONS.
Hope this helps. Good luck. -
0Votesanswered Jan 06 at 06:42PMThank you both for your answers! Given the weather at the time, it makes a lot of sense...85, sunny and dry for a day or two, 65 and rainy the next couple days. The weather was like that for several weeks and I was having problems controlling my asthma during that time. Thank goodness the seasons have finally changed.
