Why hay fever is worse this spring
Hay fever now affects almost one in four Australians, up from one in five in 2018, with this spring season proving particularly severe due to a mild, wet winter causing plants to flower up to a month earlier than usual. Sneezing is a reflex action that expels air at speeds up to 160km/h to clear irritants such as pollen, dust and viruses from airways. Thunderstorm asthma season poses additional risks as moisture breaks grass pollens into micro fragments that can trigger amplified symptoms, particularly for people with existing asthma or hay fever.
