Natural Ways to Support Your Immune System

Your immune system is working for you every single day—even when you aren't thinking about it.

It helps identify and respond to viruses, bacteria, and other potential threats while also knowing when not to overreact. And that last part is important.

We often hear about wanting to "boost" the immune system, but I prefer to think about supporting healthy immune function and regulation.

Because we don't necessarily want an immune system that's doing more.

We want one that's doing its job well.

And while there isn't one magical food, herb, supplement, or acupuncture point that makes you invincible during cold and flu season, there are many things we can do to support the systems our immune health depends on.

Why Do Some People Seem to Get Sick All the Time?

This is something patients frequently ask me.

One person catches every bug that comes through the office, while another barely gets a sniffle.

There isn't always one explanation.

Sleep, chronic stress, nutritional status, diet, age, underlying health conditions, medications, exposure, gut health, activity level, and other factors can all influence how effectively the immune system functions.

This is why I like to look at the bigger picture.

If someone tells me they're constantly getting sick or taking a long time to recover, I'm interested in why.

Are they sleeping enough?

Are they eating enough protein and nutrient-dense foods?

Are they under constant stress?

Are there nutrient deficiencies?

How is their digestive health?

Are they allowing themselves enough time to recover?

Sometimes immune support starts with surprisingly basic things.

1. Prioritize Sleep

If I could put sleep in a supplement bottle, I would probably prescribe it to almost everyone.

Sleep is one of the most important foundations of immune health.

While you sleep, your body isn't simply "turned off." It's carrying out repair, regulating hormones, consolidating memories, and coordinating important immune processes.

Consistently getting too little sleep can affect the body's immune response and may leave you more susceptible to getting sick.

Most adults should aim for approximately 7–9 hours of sleep each night, although individual needs vary.

And if you're constantly exhausted despite spending enough time in bed, that's worth investigating rather than simply accepting fatigue as normal.

2. Eat Enough Nutrient-Dense Food

Your immune system requires nutrients to function.

Protein is especially important because amino acids provide building blocks used throughout the immune system.

I encourage my patients to build meals around a quality source of protein along with colorful vegetables, fruits, healthy fats, and fiber-rich carbohydrates appropriate for their individual needs.

Some of my favorite foods to include regularly are:

• Eggs

• Chicken and turkey

• Fish and seafood

• Greek yogurt

• Citrus fruits

• Kiwi

• Berries

• Red bell peppers

• Leafy greens

• Broccoli

• Garlic

• Ginger

• Nuts and seeds

And don't forget the foods your grandmother probably would have given you when you were sick.

Soup and broth still deserve a place in the kitchen.

Chinese medicine figured out a very long time ago that warm, cooked, nourishing food can be incredibly supportive when the body is depleted.

3. Don't Forget About Protein

This deserves its own section because I see so many people—particularly women—not eating enough of it.

Protein isn't just for building muscle.

Your body needs amino acids for enzymes, hormones, tissue repair, antibodies, and many other processes involved in maintaining health.

If breakfast is coffee, lunch is a handful of crackers, and dinner is the first substantial protein you've eaten all day, we probably have some room for improvement.

Try incorporating a meaningful source of protein at each meal rather than attempting to catch up at dinner.

4. Manage Chronic Stress

We can't eliminate stress.

If you've discovered how, please call me.

But we can work on how our bodies respond to it.

Short-term stress is a normal physiological response. The problem is when the body spends day after day acting as though an emergency is happening.

Chronic psychological stress can affect sleep, digestion, appetite, hormone signaling, and immune regulation.

This is one reason nervous-system regulation is such an important part of the work I do.

Walking, spending time outside, exercising, journaling, meditation, breathing exercises, yoga, hobbies, social connection, and simply creating more recovery time can all be helpful.

And this is also one area where I frequently use acupuncture.

5. Consider Acupuncture

In Chinese medicine, supporting the body's defenses has been part of maintaining health for thousands of years.

One concept we use is Wei Qi, often described as the body's defensive Qi.

Rather than waiting until someone is sick, Chinese medicine traditionally places a great deal of emphasis on strengthening and maintaining the body so it is better prepared to adapt to changes in the environment.

Acupuncture may also influence nervous-system and immune signaling, which is one reason it continues to be studied for its potential immunomodulatory effects.

One of my favorite acupuncture points for overall health and vitality is ST-36, Zusanli, located on the lower leg.

It's one of the most famous points in Chinese medicine and has traditionally been used to strengthen Qi, support digestion, and build resilience.

But acupuncture treatments aren't based on one "immune point."

As always, I treat the person and the pattern.

6. Support Your Gut

Your digestive and immune systems are closely connected.

A large amount of immune activity occurs along the gastrointestinal tract, where the body is constantly deciding what should be tolerated and what requires a response.

That doesn't mean every immune problem starts in the gut.

But digestive health deserves attention when someone is experiencing symptoms such as chronic bloating, diarrhea, constipation, food reactions, or other ongoing gastrointestinal problems.

Supporting the gut may include looking at food quality, fiber intake, protein, digestive function, bowel regularity, stress, medications, and other individual factors.

This is another place where Chinese medicine and functional medicine can complement one another beautifully.

7. Check for Nutrient Deficiencies

More supplements aren't necessarily better.

But correcting an actual nutrient deficiency can be very important.

Some nutrients involved in normal immune function include vitamin D, zinc, vitamin C, vitamin A, selenium, iron, B vitamins, and others.

Vitamin D is one nutrient I commonly evaluate because deficiency is relatively common.

Rather than automatically taking large doses of everything labeled "immune support," I prefer a more individualized approach.

Test when appropriate.

Look at the diet.

Correct what needs correcting.

Your kitchen cabinet does not need to look like the supplement aisle at Whole Foods.

8. Use Chinese Herbal Medicine Appropriately

Chinese herbal medicine has a long history of being used both during illness and as part of maintaining health.

But there isn't one "immune formula" that's right for everyone.

A formula I might choose for someone who feels depleted, catches every cold, and has low energy could be completely different from what I would use for someone experiencing an acute illness with fever, sore throat, congestion, or thick phlegm.

One traditional formula frequently associated with supporting the body's defensive Qi is Yu Ping Feng San, often translated as Jade Windscreen Powder.

It's traditionally used for people who tend to be susceptible to external illnesses and show an underlying pattern of Qi deficiency.

But herbs work best when we choose them according to the individual.

This is why I don't believe everyone should take the same herbal formula simply because it's cold and flu season.

9. Keep Moving

Regular movement supports far more than your muscles.

Physical activity is associated with numerous benefits for metabolic, cardiovascular, mental, and immune health.

That doesn't mean you need to do an intense workout every day.

Walking counts.

Strength training counts.

Yoga counts.

Gardening counts.

Find ways to move your body consistently.

And when you're actively sick, remember that rest is productive too.

Sometimes the healthiest workout is the one you skip because your body is asking you to recover.

10. Get Outside

Fresh air and sunlight don't get nearly enough credit.

Spending time outside encourages movement, helps support your circadian rhythm, can improve mood, and provides an opportunity for sunlight exposure.

Morning outdoor light is particularly helpful for reinforcing the body's sleep-wake cycle.

And since good sleep is important for healthy immune function, you can see how these seemingly separate pieces start connecting.

Health rarely comes down to one thing.

A Chinese Medicine Perspective on Immune Health

Chinese medicine has always placed tremendous emphasis on prevention.

Rather than waiting for the body to completely break down before paying attention, we look for smaller patterns that suggest the body is struggling.

Maybe you're more tired.

You're sleeping poorly.

Your digestion has changed.

You're feeling unusually stressed.

You're getting sick more frequently.

Your recovery takes longer.

Chinese medicine asks us to notice those changes.

The goal is to nourish the body, support balance, and strengthen areas of weakness before they become bigger problems.

That's one of the reasons I love this medicine so much.

Dr. Stephanie's Tip: If you want to support your immune system, start with the foundations before buying another supplement.

Look at your sleep.

Look at your protein intake.

Look at the quality and variety of your diet.

Look at your stress.

Look at your digestion.

Look at how much you're moving.

Then, if something still seems off, that's when I want to dig deeper.

Supplements and herbs can be incredibly useful when they're addressing something your body actually needs.

But they work best as part of a strong foundation—not instead of one.

Supporting Immune Health Naturally

Immune health isn't something we should think about only when everyone around us starts coughing.

It's part of our everyday health.

Sleep, nourishing food, adequate protein, movement, stress regulation, digestive health, nutrient status, acupuncture, and Chinese herbal medicine can all be pieces of a comprehensive approach.

At New Direction Natural Medicine in Altamonte Springs, I combine acupuncture, Chinese medicine, nutrition, and functional medicine to look beyond individual symptoms and understand the bigger patterns affecting your health.

Because the best time to support your health isn't only when you're sick.

It's also while you're well.
