Can heat and humidity cause an asthama episode? I am thinking of both internal heat and humidty (a hot and stuffy room) or external heat and humidity (an August day where it is 90 degrees and 90% humidity.). I am not talking about mold from the internal source or the ozone from the external source. I mean just the heat and humidity themselves--can these cause an asthma epsiode?
I was figuring it was the warm nature of heat and humidity themselves that brought on asthma. It's July, for example, with temps and humidity in the 90's, and the stifiling air affected asthmatics' breathing. I didn't think of them containing allergens that bring on the asthma.
It actually can happen, that heat and humidity all by themselves can bring on an attack. For me, it's a minor trigger. For example, during pollen season, I have to be careful not to steam up the bathroom when I shower.
I know one woman who has heat as her PRIMARY asthma trigger, however.
Asthma triggers are so individualized. I have several friends whose asthma is highly triggered by heat & humidity, but mine loves hot humid weather. What sets me off is cool humid weather for some reason.
Correct. And they may also give you a bronchialdialator to see if it opens the airways.
So what is the actual thing/source/etc. they are giving you to see if the airways constrict?
If your airways do not constrict, does that means you do not have asthma? Or do they make the you have/don't have asthma diagnosis after they do the bronchialdialator? Also if the airways do not constrict, do they still give the bronchialdialator?
Typically they measure your lung function, then give you a drug called methacholine. That's why it's called a methacholine challenge test. After you take the drug, they measure your lung function again, to see if it decreased.
They try it several times at different doses. If you have asthma, unless it is a very mild occasional thing and not acting up at all that day, you should react.
