Back-to-School Immune Support: What to Do Before, During and After Illness
September can feel a little like Oprah hosting the world’s worst giveaway show. 🤦♀️😂
“You get a cold! And YOU get a cold! EVERYBODY gets a cold!”
Every year when school starts, it can feel almost inevitable.
The runny noses start, coughs make their rounds, someone spikes a fever, and parents start wondering when it's going to make its way into their house.
And yes, when children go back to school, there's more proximity and exposure but there are many other factors at play that determine what happens with those encounters.
There's something I want parents to know:
You aren't completely powerless in this process.
There are things we can do to support our children's and our own bodies before symptoms ever appear, strategies we can use at the earliest signs to help prevent symptoms from developing or worsening when possible, and ways we can support the body throughout an illness and into recovery.
Because immune health doesn't begin when your child wakes up with a fever.
It begins with the health of the body in the first place.
Immune Health Is About More Than Avoiding Germs
We tend to talk about cold and flu season as though the entire story begins and ends with germs.
Someone coughs in the classroom. A virus makes its rounds. Your child gets exposed. Now you wait to see what happens.
But when I think about immune health, I'm mostly interested in the body encountering that experience.
What resources does that body have available? Has it been adequately nourished? Is that child sleeping well? What's happening in the gut? Is the body carrying a significant amount of physiological stress? Are there nutrient deficiencies, environmental exposures or other health issues already asking something of the body?
These aren't separate conversations to me.
The immune system doesn't exist in its own little box, disconnected from everything else happening in the body. It is multiple systems of the body, constantly communicating and interacting with other systems, which is why I've never approached immune health as simply avoiding germs or finding the right thing to give someone once they're already sick.
I want to support the body that's doing the responding.
Your Child's Immune System Was Working Before the First Sniffle
Most of us don't think very much about the immune system when everyone feels great.
Then someone gets sick and suddenly we're pulling out the vitamin C, elderberry, thermometer, tissues and chicken soup.
But your child's immune system didn't suddenly clock in for work that morning.
It's always working.
The immune system is an extraordinarily complex network of cells, tissues, organs, signaling molecules and physical barriers that continually interacts with the world around us. It identifies potential threats, coordinates responses and communicates with other systems throughout the body.
So when I think about supporting immune function, I'm not looking for one magical “immune booster.”
I'm looking at the conditions in which that immune system is being asked to function.
That's a very different conversation.
Build the Foundation Before You Need It
One of the biggest shifts I want families to make is to stop thinking about immune support as something we pull out of the cabinet when the first cough appears.
I want us thinking about it on the ordinary Tuesday when everyone feels perfectly fine.
What has that child's body been receiving consistently?
Maybe breakfast is rushed every morning and when they do eat it's sugar disguised as cereal. Maybe bedtime has slowly crept later while the alarm still goes off at the same time. Maybe digestion hasn't been quite right for months. Or maybe another seemingly unrelated complaint has been showing up, but nobody has connected it to the bigger health picture.
This is why I keep coming back to foundations.
Good nutrition provides the raw materials the body needs. Sleep gives the body time for processes that simply don't happen the same way when we're chronically not getting enough sleep. Movement, time outdoors, hydration, healthy digestion and nervous-system regulation all become part of the environment in which the immune system is doing its job.
None of that guarantees you or your child will never get sick.
That's not what I'm promising.
I'm talking about giving the body the resources it needs to do the work it was designed to do.
And while there is research supporting many of these individual pieces—including the relationship between sleep, nutrition, physical activity and normal immune function—I don't need a study telling me that the body works as a whole before I'm willing to nourish it like one.
My Approach to "Flu Season" Is Different Too
There's another way my approach to immune health differs from the conventional one.
I personally do not use or recommend annual flu vaccination as part of an immune-health strategy.
My focus is on supporting the body's own foundations for healthy immune function and looking at the larger terrain in which that immune system is functioning. That includes nutrition and gut health, but it also includes sleep, movement, stress regulation, environmental factors and the rest of that person's health story.
I know vaccination is a deeply personal—and sometimes deeply polarizing—topic. My goal here isn't to tell you what decision to make for your family. It's to encourage you to become informed, understand both the benefits and risks of the options you're considering, ask questions and make the decision that aligns with your family's circumstances and values.
For my own family and in the way I approach immune health, I choose to focus on supporting the body rather than relying on annual flu vaccination as our primary strategy.
That philosophy goes far beyond influenza.
I don't want families moving through "cold and flu season" believing there is only one thing they can do to protect their health. There is so much we can do to support the body we're asking to carry us through it.
You may have noticed that I've been putting quotation marks around “cold and flu season.” That's intentional. There isn't actually a switch that flips in September and suddenly makes our bodies susceptible to illness. There's a much bigger story behind why respiratory illnesses increase during certain times of year—and I'll be diving into that in an upcoming article.
And Yes, We Need to Talk About the Gut
If you've been in my world for any length of time, you probably knew I wasn't going to make it through an immune-health article without bringing up the gut. 😊
There's a reason for that.
Your digestive tract isn't simply a tube where food goes in and waste comes out. It's one of the body's major interfaces with the outside world, and the gut microbiome, intestinal barrier and immune system are in constant communication with one another.
70% of your immune system is actually in your gut.
That's why I care about digestion even when someone's primary complaint doesn't sound digestive.
If a child seems to catch everything that goes around, I don't just want to know which immune supplement they're taking. I want to know what's been happening in that child's body over time.
Maybe constipation has been considered “normal” because it's been happening for years. Maybe they're frequently complaining of stomachaches. Maybe their diet has become increasingly limited, or certain foods seem to correspond with other symptoms. Maybe sleep is poor and nobody has connected that with what's happening during the day.
Those patterns matter.
Symptoms are clues. And sometimes the clue we're looking for isn't where the symptom appears.
Pay Attention When Something Feels “Off”
Parents often know something is brewing before there's an obvious illness.
You pick your child up from school and something is just...off.
Maybe they're quieter than usual or suddenly exhausted. They don't want dinner. They mention that their throat feels funny. There's the beginning of a sniffle. Or your child, who normally needs seventeen reminders to stop doing cartwheels through the living room, voluntarily curls up on the couch.
Pay attention to that.
This isn't the point when I shrug and think, Well, I guess we'll see how sick you get.
This is when I become more intentional.
I may shift the evening plans, encourage more rest, pay closer attention to hydration and nourishment, and reduce things that don't need to add to the body's workload right now. This is also when I may begin using some of the targeted nutritional, herbal and other holistic strategies I keep available.
There are strategies we can use at the earliest signs to help prevent symptoms from developing or worsening when possible.
That doesn't mean we can stop every illness. Sometimes we do everything “right” and our kids still get symptoms. Children's immune systems are developing throughout childhood, and encountering microbes is part of that process. The goal was never to create a child who never gets sick.
But not being able to control every outcome doesn't mean there's nothing we can do.
That's the difference between control and support.
I'm not trying to control every interaction my child's immune system has with the world.
I'm trying to support the body having that interaction.
What If the Symptom Isn't the Enemy?
This is one of the biggest shifts I want parents to make.
When symptoms appear, our first reaction is usually:
How do I make this stop?
A fever appears, so we want the number to come down. A child starts coughing, so we want the cough gone. Their nose starts running, so we want to dry it up.
Of course we don't want our children to be miserable. But I want to understand why the body is producing it in the first place.
Fever is a beautiful example of this.
Fever isn't simply the body malfunctioning. Raising body temperature is part of the coordinated physiological response to infection. Even conventional pediatric guidance recognizes fever as part of the body's response to illness rather than an illness itself.
Mucus and coughing have functions too. Mucus helps trap material within the respiratory tract, while coughing helps move mucus, irritants and other material through and out of the airways.
I don't automatically assume the body is doing something wrong simply because what it's doing is uncomfortable.
The body is innately smart.
When it produces a symptom, I want to understand what it's trying to accomplish before automatically deciding that the symptom itself is the problem.
That one shift can completely change the way we approach illness.
Work With the Body, Not Against It
When an adult or child is sick, my goal isn't to force the body to behave as though it isn't.
I want to pay attention to what the body is asking for and support that process while also watching how the illness is progressing.
Sometimes what the body needs isn't complicated. A child who normally has endless energy may suddenly need an afternoon on the couch. Appetite may decrease temporarily. They may sleep more. They may want simpler foods and more fluids.
I don't see those things as inconveniences I need to immediately override so we can get back to our normal schedule.
The body is doing work.
There are also nutritional, herbal, food-based and other holistic supports I may choose depending on what I'm seeing. Those are the practical strategies I go into much more deeply in my Advanced Immune Support Guide.
But even then, I'm not trying to throw twenty things at the body simply because someone has a cold.
I'm asking what makes sense for this person, at this point in the process.
That's a very different way of thinking about immune support.
When to Get Additional Support
This article is for educational purposes and isn't medical advice. There are times when getting medical attention is warranted, particularly with things like difficulty breathing, significant dehydration, seizures, unusual difficulty waking, or a child who appears seriously ill.
If you're already working with a holistic or integrative practitioner, this is also a good time to check in with someone who knows your child's history, health patterns and individual needs.
Supporting the body's natural healing processes doesn't mean we never need additional support. It means we use our tools appropriately and know when it's time to bring someone else in.
Recovery Is Part of Healing
Then comes the part that tends to get forgotten.
The fever breaks. Your child's energy comes back. They're bouncing around the house again and asking when they can go see their friends.
And mentally we check the box:
Done.
But I don't think of recovery that way.
The body has just spent time and resources responding to an illness. The disappearance of the most obvious symptoms doesn't necessarily mean everything instantly returns to baseline.
So I keep supporting the body.
That may mean extra rest, continuing to emphasize nourishing foods and fluids, giving digestion some extra attention or not immediately jumping back into every activity on the calendar.
I want to pay attention to the child in front of me rather than deciding that because the fever is gone, their body must be finished recovering.
Healing has a rhythm. We don't always need to rush it.
This Is Why Immune Health Can't Be Reduced to a Supplement
At times, I use supplements, herbs and other targeted strategies, and I teach families about many of them.
But I never want someone leaving my work believing that immune health comes down to buying the right bottle. If a child isn't sleeping well, their digestion is struggling, their diet isn't providing what their body needs, or other imbalances are asking for attention, another gummy isn't going to address the whole picture.
A supplement may be helpful. It may even be exactly what the body needs at that moment. But it is still one piece of a much larger health story.
That's why we connect the dots.
Supporting immune health means understanding the body as a whole and looking at what this particular body needs to function as well as it can. Sometimes that leads us to a supplement or targeted strategy. Other times, the most important clue leads us somewhere completely different.
And that's where individualized, whole-body care becomes so valuable.
Want to Understand Immune Health on a Deeper Level?
If you've spent years hearing about immune health primarily in terms of avoiding germs, getting vaccinated and reaching for something once you're already sick, I want to help you see the bigger picture.
Because immune health starts long before the first symptom.
In my free immune-health masterclass, I walk you through the different pieces that influence immune health and help you understand how they connect.
This isn't another random list of “immune boosters.”
It's an opportunity to understand the body you're actually trying to support.

Want the Practical Tools I Use Before, During and After Illness?
Understanding why we support the body this way is one piece.
But when your child walks in from school looking a little off, you also want to know:
Okay...what can I actually do?
That's why I created my Advanced Immune Support Guide.
I wanted families to have practical, holistic strategies they could turn to before symptoms begin, when those first subtle signs appear, throughout an illness and during recovery—without having to start researching everything from scratch every single time someone gets sick.
Because the middle of the night when your child isn't feeling well isn't when you want to discover that the thing you wish you had on hand is still sitting in your online shopping cart.

The Next Time Oprah Comes to Town... 😂
Back-to-school season brings plenty we can't control, and I'm not interested in pretending we can somehow create a life in which our children are never exposed to viruses or never get sick.
That's not what immune health means to me.
I want to raise children whose bodies are well supported before illness arrives, whose early signals we know how to pay attention to, and whose symptoms we can approach with curiosity rather than automatically assuming their bodies are doing something wrong.
When illness does happen, we can work with the body through it. And when the obvious symptoms are gone, we can remember that recovery deserves support too.
We may not control every exposure or every outcome, but that is very different from being powerless.
So when September rolls around and it feels like Oprah has taken over your child's school—you don't have to sit at home with a box of tissues simply waiting for your family's turn. 😂
You can understand what's happening in the body, pay attention to what it's communicating and have tools available to support it along the way.
Your body wants to heal.
And the more you understand how it works, the better equipped you become to support it.
To your family's health,
💖 Dr. Beata “Bye Oprah!” Harasim
Frequently Asked Questions
How can I support my child’s immune system during back-to-school season?
Start with the foundations that support healthy immune function all year long. Nutrient-dense food, adequate sleep, healthy digestion and gut function, movement, time outdoors, hydration and nervous-system regulation all contribute to the environment in which the immune system is functioning.
Immune support doesn't need to begin when your child gets sick. Supporting the body consistently—and paying attention when something starts to feel “off”—gives you an opportunity to respond before symptoms are fully underway.
What can I do at the first signs my child is getting sick?
When I notice the first subtle signs that something may be brewing, I become more intentional about supporting the body. That may include prioritizing rest, hydration and nourishment, reducing unnecessary demands on the body, and using targeted nutritional, herbal or other holistic strategies when appropriate.
There are strategies we can use at the earliest signs to help prevent symptoms from developing or worsening when possible, although no approach can guarantee that an illness won't progress.
Is getting sick always a sign of a weak immune system?
No. Getting sick doesn't automatically mean that your immune system is weak. Exposure is part of life, and children's immune systems continue developing throughout childhood.
If someone seems to get sick unusually often, has difficulty recovering, or has other ongoing symptoms, however, I want to look at the bigger health picture rather than focusing only on each individual illness.
Are fever, mucus and coughing part of the immune response?
They can be. Fever is part of the body's coordinated response to infection. Mucus helps trap material within the respiratory tract, and coughing helps move mucus, irritants and other material through and out of the airways.
Understanding the purpose of a symptom can change the way we respond to it. Symptoms are clues, and I want to understand what the body is trying to accomplish rather than automatically assuming every symptom is something the body is doing wrong.
Does gut health affect the immune system?
Yes. The gut and immune system are closely interconnected. The intestinal barrier, gut microbiome and immune system continually communicate with one another, which is one reason I pay attention to digestive health when looking at immune health.
Constipation, frequent loose stools, stomachaches, food reactions and other digestive patterns can provide useful information about the larger health picture.
Do immune supplements actually help?
Some supplements, herbs and targeted nutrients can be useful depending on the individual and the situation, but immune health can't be reduced to finding the right supplement.
A supplement is still one piece of a much larger health story. Sleep, nutrition, digestion, stress, nutrient status and other underlying factors can all influence the environment in which the immune system is functioning. That's why we connect the dots.
How can adults support their immune systems too?
The same foundational principles apply to adults. Supporting your body with nourishing food, adequate sleep, movement, healthy digestion, hydration and appropriate stress regulation matters long before symptoms appear.
Adults can also pay attention to those early signs that something feels “off” and adjust accordingly rather than waiting until they're completely run down before giving their bodies additional support.
When should I seek medical care for my child?
There are times when medical attention is warranted, particularly with difficulty breathing, significant dehydration, seizures, unusual difficulty waking or a child who appears seriously ill. This article is educational and isn't medical advice.
If you're working with a holistic or integrative practitioner, you can also check in with someone who knows your child's history, health patterns and individual needs.
