The Real Reason Kids Get Sick in the Fall—and How to Build True Resilience

It might seem early to talk about fall when we’re still in August—but in life, we always harvest what we’ve planted in the season before. That means the habits, routines, and choices we make right now will determine the level of health our families experience in the months ahead.
One of the biggest myths we continue to challenge in our office is the outdated and overblown germ theory—the idea that exposure to germs is the primary reason people get sick.
You’ve probably heard it (or said it!) before:
“I got sick because the kids went back to school.”
“I caught something babysitting the grandkids.”
“That cold went around the office—we all had it.”
But let’s pause and think critically.
If germs were the only factor, wouldn’t everyone exposed get sick? Why does the family doctor who sees sick patients all day stay healthy? Why is the teacher surrounded by 30 runny noses not constantly sick? Why did only 2 people get sick after Thanksgiving dinner, even though all 12 were exposed to the same sneezing toddler?
The answer lies in a more current and accurate model of health: the terrain theory.
This theory says it’s not the presence of germs that determines whether we get sick—but the strength and resilience of the host. In other words, the terrain matters more than the germ. A strong immune system and balanced nervous system are our best defense, not isolation or fear of microbes.
So, why do kids get sick more often in the fall? It has less to do with invisible bugs and more to do with changes that weaken their terrain. Here are some real (and often overlooked) contributors:
- Less sunlight and vitamin D
- Reduced time outdoors and fresh air
- More emotional stress (rushed mornings, school anxiety, overscheduled evenings)
- Poorer nutrition (processed “grab-and-go” snacks high in sugar and seed oils)
- Disrupted sleep (early wake-ups + late nights from extracurriculars)
- Mental/emotional strain (school, sports, peer pressure)
To keep your kids well, your focus shouldn’t be on avoiding germs—it should be on building resilience. Here’s how:
- Prioritize outdoor time, even in cooler weather
- Simplify the weekly schedule and reduce overstimulation
- Support your child’s nutrition with whole, home-cooked foods
- Prioritize consistent, restful sleep
- Supplement with vitamin D, if needed
- And crucially, support their nervous system with regular chiropractic care
We see it time and time again—kids under chiropractic care tend to be more balanced, adaptable, and resilient, especially during high-stress seasons like the fall. If your children aren’t yet getting adjusted, now is the perfect time to start.
