Welcome to #BritainBreathing! Hay fever & asthma are increasing and we don’t know why! Is it down to our environment- the pollutants or pollens we are exposed to? Is it increased cleanliness and lack of exposure to childhood germs or is it a lack of parasitic worms? Maybe it is a combination of lots of factors? We invite you to come and learn about the biggest science experiment of its kind that will try and find answers to these unanswered questions about allergies and you can even join in the experiment. Together we can learn more about when, where and why allergies occur! See how our lungs work and how they are changed in asthma.
