B747-400 drivers
I'm pretty new here but had a quick question......I've noticed on some, not all, flights, after 4-5 hours it gets a bit difficult to take a large breath without getting a funny feeling(almost borderline wheez/winded) in my chest....if I take a real deep breath, I cough.....I've heard it may be due to the lack of moisture in the air but am not positive.
Has anyone else experienced this and if so, what countermeasures, if any are there?
Thanks

PS...this has nothing to do with HK's air so no joking from this side.
