Weekly Insight: Stress & Your Immune system
It’s officially full back-to-school season.
Some kids went back a month ago (like mine).
Others are just in their first few weeks.
And that means a lot of things…
But the harsh reality? Back to school comes with more stress and more germs.
A terrible combination if you want to avoid getting sick.
I’ve been learning this lesson firsthand.
On my functional health journey at Stat Wellness, I just got back the results from a blood panel and GI Map.
It turns out my immune system is wrecked.
Here’s what’s interesting: my cortisol was normal (a big win after years of working on nervous system regulation).
But stress leaves fingerprints. Even when cortisol looks good, years of living in fight-or-flight can take a toll.
For me, it showed up in my gut and in suppressed immune function.
How stress impacts your immune system
Chronic stress shifts your body into survival mode.
→ Cortisol suppresses certain immune responses, making it harder to fight off infections.
→ Stress disrupts the gut microbiome, where 70% of your immune system actually lives.
→ Over time, this leads to more inflammation, slower recovery, and a higher chance of picking up whatever bug your kids bring home.
What you can do this fall
Supporting your immune system isn’t about perfection, it’s about stacking small wins:
- Prioritize sleep: 7–9 hours is the most powerful immune booster
- Eat protein with every meal: Amino acids are critical for antibody production
- Load up on micronutrients: Vitamin C, zinc, and magnesium all play immune-supporting roles
- Manage stress daily: Walks, breathing, journaling, prayer, meditation—anything that signals safety to your nervous system
- Gut support: Prebiotics (fiber) + probiotics (fermented foods or supplements) help rebuild balance
- Boundaries: Protect downtime so your body has space to recover.
Back-to-school germs aren’t going away anytime soon.
But when your body feels safe and supported, your immune system is better equipped to do its job.
