Why Kids Pick Up More Viruses When They Go Back to School — and How to Help Protect Them
The start of a new school term brings fresh pencils, new friends, and plenty of excitement.
Unfortunately, it often brings something else too — runny noses, coughs, and fevers.
If you’ve ever wondered why your child seems to get sick more often once they’re back in the classroom, you’re not alone. Here’s what’s going on, and what you can do to help keep those bugs at bay.
Why Back to School Means More Viruses?
-
Close Contact With Lots of Kids
Children spend hours each day in close proximity to classmates, often sharing books, toys, and even snacks. Viruses that cause colds, flu, and other illnesses spread easily in these settings. -
Immune Systems Meeting New Germs
Every school term introduces your child to a fresh mix of germs their body hasn’t seen before. It’s normal for their immune system to be “training” — especially in younger kids. -
Seasonal Changes
Many school terms start as the weather shifts, which can make certain viruses more common. Cooler air means more time indoors and less ventilation, allowing germs to circulate. -
Shared Surfaces
Desks, doorknobs, playground equipment, and shared supplies are touched by dozens of little hands each day — a perfect way for germs to travel. -
Tiredness and Stress
New schedules, earlier mornings, and after-school activities can tire kids out. Fatigue and stress can lower immunity, making it harder to fight off bugs.
How to Help Protect Your Child
-
Prioritize Handwashing
Encourage regular handwashing with soap for at least 20 seconds — especially before eating and after using the toilet. -
Teach “Catch It, Bin It, Kill It”
Show kids how to sneeze or cough into a tissue (or their elbow if there’s no tissue) and then wash their hands. -
Boost Nutrition
A balanced diet with fruits, vegetables, and immune-supporting nutrients like Vitamin C, Vitamin D, and Zinc helps keep defences strong.
Tip: Daily multivitamins can help fill in nutritional gaps, especially during busy school weeks. -
Prioritize Sleep
School-aged children need 9–12 hours of sleep. Adequate rest keeps immune systems strong. -
Stay Active
Outdoor play and regular exercise support overall health and help kids sleep better. -
Teach No-Sharing Rules (For Certain Things!)
While sharing toys is fine, explain that sharing water bottles, cutlery, or lip balms can pass along germs.
When to Keep Kids at Home
If your child has a fever, is vomiting or just too unwell to be in school it’s best to let them rest at home to recover and avoid spreading illness.
Final Thoughts
Catching the occasional bug is part of building a healthy immune system, but with good hygiene habits, strong nutrition, and plenty of rest, you can help reduce the number of sick days this school year.
A little preparation now means your child can spend more time learning, laughing, and enjoying the school term — and less time curled up with a tissue box.
