It is estimated that millions of people in the UK suffer from pollen exposure every year, according to the UK Health Security Agency (UKHSA).
Hay fever season begins around March when blossoming trees release pollen - but there are overlapping pollen phases that can extend hay fever symptoms into October and early November. Grass pollen wreaks havoc on hay fever sufferers from May through July, while weed pollen - like dock and mugwort - begins in June and can cause symptoms until near the end of the year. Other common weed pollens are nettles, ragweed, and ribwort, says Allergy UK .
These are most active in September and October - particularly ragweed, which can trigger sneezing and itchy eyes. Approximately 75 percent of those allergic to pollen are sensitive to ragweed, according to Kleenex . Due to climate change, the pollen season can now begin as early as January or February depending on weather patterns, says UKHSA, meaning that spring hay fever can start shortly after autumn hay fever subsides.
