Snot serves as a critical barrier against pathogens and pollutants while providing visual health clues through its color and texture. Researchers are leveraging nasal mucus to develop diagnostic tools for diseases ranging from asthma to neurodegenerative disorders. A recent study demonstrated that transplanting healthy snot reduced respiratory symptoms by 40% in chronic patients. Scientists are now mapping the ‘ideal snot microbiome’ to create nasal probiotics that could enhance immunity and vaccine response. With new microsampling technologies and AI analysis emerging, experts predict snot will become central to personalized medicine.
