Early exposure to infections doesn’t protect against allergies, but getting into nature might - The Conversation
Over the past few decades, allergies and asthma have become common childhood diseases, especially in developed countries. Almost 20% of Australians experience some kind of allergy, whether it’s to food, pollen, dust, housemites, mould or animals.
When people suffer from food allergies, hay fever or asthma, their immune system incorrectly believes the trigger substances are harmful and mounts a defense.
The response can range from mild symptoms, such as sneezing and a blocked nose (in the case of hay fever), to anaphylaxis (from severe food allergies or bee stings) and asthma attacks.
