Health tips for students facing seasonal allergies and infections

As the school season begins and seasonal weather changes occur, children face increased risks of cross-infection and respiratory or skin sensitivities. Medical research highlights the importance of the gut barrier, noting that over 70% of immune cells are concentrated in the intestinal mucosa. A compromised gut barrier can lead to systemic reactions, including eczema and respiratory allergies, via the gut-skin and gut-lung axes.

To support immune health, experts suggest focusing on specific probiotic strains rather than high-quantity multi-strain products, which may cause nutrient competition. Lactobacillus reuteri DSM 17938 is noted for its high survival rate in the digestive tract and its ability to inhibit harmful bacteria without disrupting beneficial flora. Additionally, combining probiotics with Vitamin D may help strengthen the intestinal epithelial junctions to prevent allergen invasion.
