Most pollen-related asthma health issues in children occur in the colder part of the year, while adults are affected in the warm season, according to a study of pollen levels and hospitalisations in South Australia. The researchers looked at 15 years of grass, weed and tree pollen counts alongside hospital and ambulance data and found that for children, the riskiest period for grass pollen-related attacks was autumn (May). The authors say that they found peaks of asthma occurring in both late summer-autumn and in late winter-spring, which suggests a need for asthma vigilance across the year rather than just focusing on spring.
