Allergic diseases, including asthma, allergic rhinitis, and atopic dermatitis, have increasingly become a global health concern, with their prevalence rising sharply over the past few decades. This surge in allergic conditions has long baffled scientists and medical professionals, prompting ongoing research into potential causes and solutions.
