BESIDES being stuck inside while the sun is shining, office workers are likely to be surrounded by sneezing, sniffling colleagues over the next few months, suffering from what has been predicted to be a particularly allergy inducing spring.
An infectious diseases and immunology researcher, Jason Sercombe, said recent wet weather has created perfect conditions for hay fever.
''When we have a lot of rain and then a dry, warmer period, it creates a lot of plant growth,'' said Mr Sercombe, who is from the University of Sydney. ''Plants are now flowering profusely and therefore there's a lot of pollen in the air.''
But the most problematic plants were not those with obvious flowers and pollen.
''Because those plants are mainly pollinated by insects, the pollen they produce is designed to be sticky so that it can be better carried by bees and doesn't float in air,'' he said.
''But some trees, weeds are shrubs that have evolved so that their pollen floats through the air and remains airborne for a long period of time. That is what usually causes the most problem for people.''
Grasses also produced their pollen in the spring, he said, which was why lawn-mowing could become torturous for some.
The weatherzone.com.au site says pollen in the atmosphere is highest on hot days with a dry wind or when there has been light rain overnight or early morning.
