Before I'll feel comfortable giving an answer beyond what's already been shared (all of which, I would fully vouch for, btw), I'd need to know more of the symptoms, versus your normal. For example, are you normally warm? Or do you run cool? Is your body normally on the moist side? Or do you have dryer skin? Do you already have asthma or other lung problems? How is your heart? Obviously, these aren't necessarily questions to answer publicly, but beyond what's been suggested already, they're important to know before recommending anything with more intense effects.
That said, I remember another thread about helping the lungs through the wildfires, last year. I'll see if I can find it, and link it, here.
P.s. Check out the 'similar threads list, below, for more info.
