Reader's Digest UK|February 2020
According to the european academy of allergy and clinical immunology, more than 150 million europeans suffer from chronic allergic diseases—and they predict that by 2025, half of the entire eu population will be affected. But why are allergies on the increase, and how can we stop them developing further?

Why Are Allergies On The Rise?

Let ’s start at the beginning: what exactly qualifies as an allergy? “It’s a reaction modulated by your immune system, where it recognises something as foreign and reacts to it with a high degree of reactivity,” says Dr Adrian Morris, Adult and Paediatric Allergy Consultant. Allergens can come in many shapes and forms, from food and pollen to fur and dust. “Normally your body tolerates these things and nothing happens,” Dr Morris continues, “but if your immune system thinks something dangerous is attacking it, it’ll react and try to fight it.”

The rise in allergies has been swift in recent years—according to research by Mintel, around 44 per cent of British adults now suffer from at least one allergy, the numbers growing by roughly two million between 2008 and 2009 alone. But allergies have actually existed for a long time; it’s thought that rashes, red eyes and runny noses could even date back as far as Ancient Greece. Scientific progress into allergies only really began to advance in the 19th century; the first known recording of hay fever was made in 1819 by Liverpudlian doctor John Bostock, and it was another 50 years until Dr Charles Blackley connected it to pollen. So it’s perhaps truer to say that allergies became far more diagnosable around the beginning of the 20th century, and the continual discovery of new allergens makes them more ubiquitous than ever.
