The Real Reason Why You Have Allergies
In this video, Kurzgesagt – In a Nutshell explores the surprising evolutionary origins of allergies, proposing they are an accidental byproduct of humanity's success in eradicating parasitic worms. Historically, our immune systems developed aggressive defenses, like IgE antibodies and mast cells, to combat constant worm infections. With modern hygiene, these worms largely disappeared, leaving an overzealous immune system that now misidentifies harmless substances like pollen or food as dangerous invaders, triggering violent allergic reactions. The video explains the cellular mechanisms behind these reactions and discusses the global rise of allergies, linking it to improved sanitation.
