Southern Hemisphere v northern

Hi there, my wife is a sufferer and we recently flew form London to Melbourne for a holiday. My wife was dreading the trip as long haul flights to Japan have triggered her attacks. However once in Melbourne the time of the attacks moved from 3-4pm to 7-8am (body clock at work?) but more importantly where much, much milder. When we returned to UK last weekend the attacks returned to normal. Does anyone have a theory of why they subsided so much in Australia? Cleaner air? More UV Rays? Air pressure? Anything greatly accepted. We will try to go there again soon and see if this was a one off event. 

 

Thanks in advance,

Russ

As soon as the engines start before the plane gets push back from the pier i get a cluster. I have now given up air travel and using cruise holidays.

 

an interesting article here about the air is recycled from the engine cooling and it could be the fumes that trigger the attacks

Thanks Duetto but what I am actually trying to find out is if there would be any reason attacks would be more moderate if you were in Melbourne or somewhere else in the southern hemisphere-Does cleaner air and higher UV ray penetration have an influence?My understanding of CH is they are possibly/ probably triggered by environmental stimulus. Any views on this very greatly received!

hi russ welcome to the ouch page,  you could be on to somthing, thers a lot of talk about wether and atmospherc pressure changes that trigger attacks but i cant find any data or reserch in that area, im looking for a certifide barometer for this perpose, but thay cost a lot so useing bbc wether site for this reason, but the bbc not accurate, igot this data from a vergin air craft tecnision,  "the cabin is pressurised between 750-800 milibars,(very stormy on the barometerscale) which is the same altitude of 7000-8000 feet. the time taken to pressurise the cabin is usuly about 7 to 8 minutes depending on rate of climb as this is controlled by computer and adjusted by the rate of climb itself"  im intrested in the rapid changes of pressure on head aches hi and low, so if anyone has accsess to a barmoic chamber or a cole mine as deep as possible let  this cch lab rat know please, we could find some interesting data or set a record for the highest and lowest ch attack, all the best dh
