I scuba dive and fly small unpressureized airplanes.
When I dive, any sign of HA's tend to disappear. I use recreational scuba air and dive depths down to 2 ATM (~130 feet). I don't know if it is the regular breathing or the pressurization at depth.
As for flying, I have noticed that I have been getting a bad CH-attack on the 2nd flight of the day. I usually fly one-time in the AM for a business meeting and return on a 2nd flight that evening. I *think* 5,000 MSL is about .7 ATM, but I am probably wrong.
The O2 doesn't help in this situation, but then O2 doesn't seem to help at sea-level, well 30 feet (I live in Houston).
I have started to wonder if the pressurization difference has any bearing on my CH-situation.
