How to Support Immune Health Naturally This Cold Season
If you want to support immune health naturally this cold season, start with the basics: wash your hands, improve indoor air quality, prioritize sleep, eat whole foods, stay hydrated, and reduce unnecessary chemical exposures.
There is no magic supplement that can replace those habits. For our family, supporting immune health is about creating a strong foundation and making simple, thoughtful choices every day.
Here is what our cold-season routine looks like.
1. Wash Your Hands With Plain Soap and Water
Handwashing is one of the simplest ways to reduce the spread of germs, and you do not need antibacterial soap to do it.
The FDA says there is not sufficient evidence that over-the-counter antibacterial soaps are more effective than plain soap and water at preventing illness. In 2016, the FDA also removed triclosan and several other ingredients from consumer antiseptic wash products that could be marketed without premarket review.
For everyday use, I prefer a simple soap with an ingredient list I recognize. If you want a scented option, look for one that uses essential oils rather than unnecessary synthetic fragrance.
The most important thing is not the label on the bottle. It is washing your hands thoroughly and consistently.
Focus on washing:
- Before eating or preparing food
- After using the bathroom
- After coughing, sneezing, or blowing your nose
- After being in public places
- Before and after caring for someone who is sick
- After handling trash or other dirty materials
2. Choose Your Hand Sanitizer Carefully
Soap and water are always my first choice, but hand sanitizer is useful when there is no sink nearby.
The CDC recommends using an alcohol-based hand sanitizer containing at least 60% alcohol when soap and water are unavailable.
I also pay attention to the rest of the ingredient list. When there are comparable options, I prefer to skip unnecessary synthetic fragrance and other additives.
Think of sanitizer as the backup plan, not a replacement for handwashing.
3. Pay Attention to Indoor Air Quality
The cold season means more time indoors, which makes indoor air quality worth considering.
The EPA recommends three main approaches to improving indoor air: source control, ventilation, and filtration. Portable air cleaners can be useful as part of that strategy by reducing airborne particles.
Air purifiers help filter particles from the air in our home. However, I do not think it should be treated as a magic shield against getting sick. When outdoor conditions allow, opening windows and bringing in fresh air is still important. I also try to reduce pollution at the source by being mindful about fragrances, smoke, cleaning products, dust, and other things we introduce into the home.
Cleaner air starts with what you put into the room in the first place.
4. Do Not Skip the Basics
Before adding another supplement to your routine, consider what you are already doing every day.
Sleep. Food. Hydration. Movement. Time outside.
These habits may not be exciting, but they form the foundation of overall health.
Protect your bedtime whenever possible. Get outside during daylight hours. Drink enough water. Build meals around whole foods, adequate protein, fruits, and vegetables.
You do not need a perfect wellness routine. It’s important to create habits you can actually maintain.
5. Be Thoughtful About Supplements
Supplements can have a place in a healthy routine, but more is not automatically better.
For our girls, we use Llama Naturals gummies. I like that they are made from whole fruit, contain no added sugar, and that the company shares information about its third-party testing.
That transparency matters to me when I am choosing something to give my kids.
And, perhaps just as importantly, my girls actually like them.
Still, I consider supplements exactly that: supplements. They are not a replacement for a balanced diet, adequate sleep, or appropriate medical care.
If you or your child has specific nutritional needs, takes medication, or has an underlying health condition, talk with your healthcare professional before adding a supplement.
6. What About Elderberry Syrup?
Elderberry is another popular cold-season remedy, and we like keeping elderberry syrup around during the colder months.
The NIH’s National Center for Complementary and Integrative Health says preliminary studies suggest elderberry may help with symptoms of some respiratory infections. I think of elderberry as an optional addition to a healthy routine. You can go to my elderberry syrup recipe from this week.
7. Do Not Confuse “Clean” With “Chemical-Free”
When cold and flu season arrives, it is easy to feel like you need to disinfect everything in your home. More cleaning products. More sprays. More disinfectants.
Because we spend so much more time indoors during the colder months, it is worth paying attention to what we are adding to the air we breathe every day.
For everyday cleaning, I prefer simple products and use the least aggressive option that makes sense for the job. I also try to avoid unnecessary synthetic fragrance, especially in products that are used frequently or sprayed into the air.
As we focus on keeping our homes clean during the cold season, we should also ask another question: What else are we putting into the air we breathe every day?
8. You Do Not Need a Germ-Free Home
There is one more thing worth remembering during the cold season: supporting immune health does not mean eliminating every germ from your environment.
Kids are going to touch things. They are going to play outside. They are going to get dirty. That is normal.
The goal of a non-toxic lifestyle is not to create a sterile bubble. It is to reduce unnecessary exposures and create an environment that supports health without turning everyday life into a constant cleaning project.
Our Cold-Season Immune Health Checklist
If I had to simplify everything into one routine, it would look like this:
- Wash hands: Use plain soap and water whenever possible.
- Use sanitizer when needed: Choose one with at least 60% alcohol.
- Clean up your indoor air: Reduce pollution sources, ventilate when possible, and use appropriate filtration.
- Choose cleaning products thoughtfully: Avoid unnecessary fragrance and use the least aggressive option that makes sense for the job.
- Prioritize sleep: Protect a consistent sleep routine.
- Eat real food: Focus on whole foods and adequate protein.
- Stay hydrated: Make water part of your daily routine.
- Get outside: Make daylight and movement a priority.
- Be selective with supplements: Look for quality and transparency.
- Treat elderberry as another option.
You can do everything “right” and still catch a cold. What we can control is the foundation we build around it.
Frequently Asked Questions About Immune Health
What is the best way to support immune health naturally? Start with the basics: adequate sleep, a balanced diet, hydration, regular movement, good hand hygiene, and a healthy indoor environment. Supplements can complement these habits but should not replace them.
Is antibacterial soap better than regular soap? No. The FDA says there is not sufficient evidence that consumer antibacterial soaps are more effective than plain soap and water at preventing illness.
What should I look for in hand sanitizer? When soap and water are unavailable, the CDC recommends an alcohol-based hand sanitizer containing at least 60% alcohol. You can also look for a simple ingredient list and avoid unnecessary fragrance and additives.
Can an air purifier help during the cold season? Air purifiers can help reduce airborne particles indoors, but they should be considered one part of a broader indoor-air strategy that includes source control and ventilation.
