Climate change will double hay fever allergies

A new study by researchers at the University of East Anglia and colleagues, found that for just one type of pollen, that of the ragweed Ambrosia artemisifolia, the number of people likely to suffer will more than double from 33 million to an estimated 77 million around 2050. The study claims to be the first to consider the big picture of how climate change affects a human pollen allergy, from a plant’s distribution to the health effects on populations.

Put simply, hay fever is a common allergic reaction that occurs at particular times of the year. It is known as seasonal rhinitis, sharing symptoms with perennial (year-round) allergic rhinitis, but it occurs as a reaction to pollen from grass, trees, and weeds during the early spring and summer months. It can affect both adults and children.

Grass pollen is the most common allergen (May to July), but tree (February to June) and weed (June to September) pollen can also cause hay fever. In perennial allergic rhinitis, the symptoms sometimes continue all year round and are usually linked to indoor allergens like house dust mites, pets, including birds, or moulds.

With temperatures also predicted to increase, it is no secret that more people will be investing in air conditioning systems than ever before. Speaking of which, a lot of people use air conditioning systems as a way to keep their homes cool without needing to allow allergens to make their way into their homes through open windows and doors.
