I have suffered from hayfever for a long time.  My symptoms tend to be quite severe.  I get the usual itchy eyes and sneezing.  However, I also get itchy all over my body.  Worse still, I can't sleep when I have hayfever.  Not even sedating antihistamines like Polaramine help.

I have lived in Auckland and Sydney over the last twenty years.  However, I moved to Perth (Perth, Australia) last year and this year experienced hayfever that was utterly debilitating.  It lasted for five months and I averaged only three to four hours of fitful sleep throughout that five months.

This experience has made me realise that the climate in Perth - which is hot and dry - is not suitable for me.  I have been trying to locate information on the type of climate that would better suit an individual like me.  I gather that tropical climates are better; and I must say that when I holidayed in Singapore from December 2007 to March 2008, I didn't have hayfever.

I've been trying to find something like a register of countries with hayfever 'ratings' on the internet, but so far to no avail.

On a final note, I read in the news that Perth's pollen count was rising to 400 and beyond this year, which I gather is very extreme.

So I want to identify countries that don't experience these extremes - or at least identify more conducive climate 'types' than the type I've experience in Perth!

On a final note, when I lasted tested for allergies - back in New Zealand - the tests revealed allergies to grass pollens and perennial ryegrass.

I would be very grateful for any advice.
