Top 12 Immune Support Strategies to Prevent Illness
Your immune system is a complex system that protects you from viruses, bacteria, parasites, and other pathogens. It is a complex system that’s essential for your health and survival. Optimal immune support is important for your health at all times. However, currently, as we are facing the COVID-19 pandemic, dealing with flu season, and experiencing a stressful time in our world, immune support strategies have become even more critical to support your body and to prevent illness.
In this article, you will learn more about the immune system and the importance of supporting a balanced immune response. I will share my top 12 immune support strategies to prevent illness and to protect your health.
What is the Immune System
Your immune system is absolutely essential for your health and survival. Your immune system keeps you healthy and protects your body from viruses, bacteria, parasites, fungi, and other pathogens.
If you want to understand your immune system, imagine a network of cells and tissues spread throughout your body involving your cells, tissues, and organ. Your immune system is on a constant lookout for invaders and ready to attack and protect you through a so-called immune response. It is your defense system and inner-army of protection (1, 2, 3, 4).
Parts of the Immune System
White blood cells, or leukocytes, are some of the main characters in your immune system. They are found in various lymphoid organs, including your thymus, spleen, bone marrow, and lymph nodes. They circulate across your body through blood vessels and lymphatic vessels. They are on the look-out for pathogens, and when noticing one, they multiply and urge others to do the same.
There are two kinds of leukocytes. Phagocytes, including mast cells, monocytes, macrophages, and neutrophils, absorb and break down pathogens by eating them. Lymphocytes recognize previous invaders and attack them if they show up. B lymphocytes make antibodies and let the T lymphocytes know when pathogens show up. T lymphocytes kill compromised cells and alert other leukocytes for help (1, 2, 3, 4).
Immune Response Process
Antigens are any substances that are considered to be an invader. They prompt an immune response. They include viruses, bacteria, fungi, toxins, or other foreign materials. When your B lymphocytes, or B cells, spot an antigen, they release antibodies. Antibodies are part of the immunoglobin family and are a type of protein that can lock antigens.
Each antibody has a special function and can help to protect you from a specific antigen. For example, you have different antibodies for the common cold than for the flu or pneumonia. One of the problems we are facing today with the novel coronavirus (COVID-19) is that because it is a new virus, we do not have antibodies against it. Antibodies attach to antigens and mark them as cells called phagocytes in order to kill them.
T lymphocytes, also called T cells or Th cells help to coordinate the immune response. They communicate with cells, prompt B cells to produce antibodies and phagocytes to kill antigens. Killer T cells or cytotoxic T lymphocytes can also fight other cells and are especially important for fighting viruses and destroying cells infected by a virus (1, 2, 3, 4).
Types of Immunity
Once your body creates an antibody it stays in your body forever. This storage is the reason why you cannot get the chickenpox twice and helps your body fight other infections and illnesses. This protection from your immune system is called immunity.
There are several types of immunity:
- Innate immunity: This is the immunity you are born with that allows your body to fight pathogens until you develop adaptive immunity.
- Adaptive immunity: This form of immunity is also called acquired immunity. It is a library of antibodies that your body develops through being exposed to and fighting off pathogens throughout your life.
- Passive immunity: This is a form of immunity that includes a baby’s protection through the placenta or breast milk and lasts for a certain period to protect the body until it can defend itself.
- Immunization: Immunization exposes your body to antigens and weakened pathogens to protect your body from specific infections and illness in the future.
Immune System Problems
Your immune system is a very complex system, hence there are various ways it can get out of balance and become compromised.
You may develop an immunodeficiency that means that one or several parts of your immune system cannot function optimally. Immunodeficiencies may develop for a variety of reasons, including genetic defects from birth, age, obesity, malnutrition, infections and alcoholism. AIDS is a form of immunodeficiency acquired from an infection with the HIV virus.
You may develop autoimmunity or an autoimmune condition. This means that your immune system attacks and destroys cells in your body mistaking them for pathogens or compromised cells. Autoimmune conditions include Celiac disease, Hashimoto’s disease, rheumatoid arthritis, type 1 diabetes, and lupus.
Hypersensitivity means that your immune system overreacts to something and damages healthy cells. Anaphylactic shock due to an allergen is one example of this.
Even if you don’t have any of these immune system problems, unhealthy lifestyle and dietary choices, toxins, and stress can weaken your immune system and thus compromise your immune system response making you more vulnerable to illness and making recovery more difficult.
Supporting a Balanced Immune Response
Your immune system is a complex entity that works hard every moment of every day to protect you from infections and illnesses. When it is out of balance, suppressed, or overstimulated, it cannot function optimally.
Your T cells help to coordinate immune regulation and kill compromised cells. However, T cell function decreases as you age and lowers immunity, especially in older adults. This is why respiratory infections, influenza, and pneumonia cause more risk and are among the leading causes of death in those over 65. Unhealthy lifestyle choices, including an inflammatory diet, lack of exercise, smoking, inadequate sleep, chronic stress, and improper hygiene can also compromise your immunity and make you more prone to disease.
Supporting a balanced immune response is critical for your health and well-being. The good news is that it is never too late to start making dietary and lifestyle changes to support proper T cell function and immune regulation (5, 6, 7, 8).
Top 12 Immune Support Strategies
Supporting your immune system is important no matter what. You want your body to be strong and healthy so that it can protect you from infections, illness, and disease. Now as we are dealing with the novel coronavirus or COVID-19 pandemic and the flu season both while experiencing an uncertain time in our world, immune support strategies are critical for protecting your health.
Be Grateful & Positive
Chronic stress can be detrimental to your immune system, increase inflammation, and make you more vulnerable to infections and illness. Being grateful and keeping a positive mindset is more important than ever before to lower your stress level and protect your immune system. Keep a daily gratitude journal. Stop several times a day to be thankful for the good things. You can even set a timer on your phone to remind you to practice a moment of gratitude.
Engage in uplifting activities, such as dancing in your living room, playing with your kids or pets, watching a comedy, listening to music, or reading your favorite book. Say a prayer or practice any spiritual activities that feel right for you. If you need help in developing a positive mindset, seek help from a counselor, therapist, or life coach. Many are available online.
Prioritize Good Sleep For Immune Support
Getting poor sleep on a regular basis can lead to increased stress, high inflammation, and lower immunity. Make sleep a priority. Make sure to go to bed and wake up around the same time each day to help your circadian rhythm. Develop a nighttime routine that supports relaxation.
Avoid electronics and instead try board games, reading, relaxing music, crossword puzzles, crafts, coloring, meditation, and journaling. Make sure your bedroom is a safe sanctuary with a comfortable bed, bedding, and pillows (9).
Avoid Sugar & Processed Foods
Sugar and processed foods are extremely inflammatory to your body. Chronic inflammation can lead to poor immune function which increases your risk of infection and disease.
Avoid processed foods and foods that are high in refined sugar, refined oils, gluten, conventional dairy, artificial ingredients, coloring, and additives. Choose an inflammatory diet rich in greens, vegetables, fruits, clean protein, and healthy fats (10).
Practice Intermittent Fasting For Immune Support
Intermittent fasting is a strategy that involves fasting (not eating) for a period of time followed by a period of feasting (eating). Intermittent fasting increases autophagy, cellular rejuvenation, immune system function, and genetic repair. It reduces inflammation and the risk of disease.
I recommend that you start out with a Simple Fast that involves 12 hours of fasting including your overnight sleep. Slowly increase your fasting time and graduate to Strong Fast or 16:8 Fast with a 16-hour fasting window. I explain different fasting strategies and how to get started with intermittent fasting in this article. To learn more about the benefits of fasting, read this article (11, 12, 13, 14, 15, 16, 17, 18, 19).
Consume Immune-Supportive Foods
Eat an immune-supporting, anti-inflammatory, nutrient-dense diet. Focus on organic greens including chard, kale, and spinach, vegetables, including cucumber, celery, and broccoli, herbs and spices including turmeric, ginger, basil, and mint, low glycemic index fruits including lemon, lime, and berries, healthy fats including avocado, coconut oil, extra virgin olive oil, grass-fed butter, and ghee, clean protein including grass-fed beef, free-range poultry and eggs, wild-caught fish, and wild boar, fermented foods including kimchi, sauerkraut, and kefir, and medicinal mushrooms including reishi, cordyceps, and turkey tail.
Choose home-cooked meals whenever possible. As we are spending more time at home during the COVD-19 pandemic, it may be a great opportunity for you and your family to start cooking more and to try new recipes that support the immune system. My recipe directory is full of delicious, immune-supporting options that you and your family will love (10).
Fresh Air, Sunshine, and Grounding
Being outdoors has endless benefits. Being in the sunshine can increase your vitamin D levels which are important for optimal immune function. Sunshine can also improve your mood, reduce stress, and elevate depression and anxiety. Breathing the fresh air helps to clear your lungs. Grounding, standing or walking on dirt, grass, or sand, can help you connect you to the earth and improve your physical and mental health (20, 21).
I know that at this current time of the COVID-19 pandemic, your time outdoors may be limited. However, step outside to your garden, yard, balcony, or street in front of your house or apartment as much as you can. Open the windows to let the fresh air in. Grow some plants to allow nature to be present inside. Go for a walk or a jog while keeping the recommended social distance in order to uplift your spirit and improve your immune system during this time.
Regular Movement & Exercise
Regular movement and exercise are particularly important for a healthy immune system. It improves your lung function, cardiovascular health, mood, and energy levels while reducing inflammation and building strength and muscle. Make sure to exercise 20-30 minutes a day.
Mix up cardiovascular exercises, such as walking, running, biking, or dance, as well as resistance and strength training including weight lifting, CrossFit, TRX, and pilates. High-intensity interval training (HIIT) provides the benefits of both (10).
Even if you have to stay at home while we fight the COVID-19 crisis you may find many free workouts online and on youtube which you can follow at home, including yoga, pilates, HIIT, Zumba, kettlebell, TRX, weight lifting, and other types of workouts. Make sure to stay active throughout the day. Even if you are home, make sure to take time throughout the day to stretch, do a yoga sequence, walk around the room, dance for your favorite songs, or if possible, go outside for a short walk or try gardening.
Good Hydration & Drink Herbal Teas
Good hydration is essential for a healthy immune function. I recommend that you drink 8 to 10 glasses of clean water minimum a day. If you are exercising, spend time outside in the sun. If you are recovering from an illness or infection, or otherwise feeling dehydrated, drink more. Listen to your body.
I recommend systems like iSpring or the Berkey system for low cost filtration. The best water is the Synergy Science hydrogen water which is what I use at home as it is powered by molecular hydrogen which reduces oxidative stress in the body and improves immune function. Add a slice of lime for some extra flavor. Additionally, I recommend drinking herbal tea as well. Echinacea, ginger, and peppermint are fantastic options for immune support (10).
Optimize Vitamin D Levels
Vitamin D is essential for healthy immune function. While the sun is your best friend for boosting vitamin D, chances are you don’t spend enough time outside in the sun to meet your needs.
Vitamin D-rich foods, including fatty fish, beef liver, and egg yolks offer some support, but not enough to optimize your vitamin D levels. To boost your vitamin D levels, I recommend that you take a daily Vitamin D3/K2 supplement for immune support (22).
Take Probiotics & Digestive Enzymes
Your gut health and immune health are interconnected. Keeping your gut microbiome balanced is absolutely critical for a healthy immune system. For digestive support, I recommend Super D-Zyme, a powerful digestive enzyme that benefits your digestion, enhances nutrient absorption and helps the breakdown of lactose and polysaccharides.
Take it daily with each meal. For microbiome balance and probiotic support, I recommend SBO Probiotics for maximum probiotic support. Take it daily for optimal gut and immune health benefits (23, 24).
Use Vitamin C & Zinc For Immune Support
Vitamin C and zinc are both essential for immune health. Vitamin C-rich foods include lemon, lime, oranges, mandarins, grapefruits, guava, strawberries, papaya, pineapples, kiwi, sweet green pepper, broccoli, and brussels sprouts.
Foods that are rich in zinc include spinach, pumpkin seeds, salmon, and grass-fed dairy. Additionally, I recommend that you supplement with Super C and Zinc Charge for optimal immune support (25, 26, 27, 28).
Use an Infrared Sauna For Immune Support
Infrared saunas have countless health benefits. They support detoxification, improve immune health, reduce stress, and improve energy. To learn more about the benefits of infrared saunas, read this article.
For optimal immune support and health benefits, I recommend an infrared sauna by Synergy Science as a great affordable option with safe, deep penetrating, detoxifying, and immune-supporting benefits (29, 30, 31, 32).
Bonus Strategy: 3-Day Fast or Partial Fast
If you are not feeling well or simply want an extra immune system boost, I recommend that you do a 3-day fast or a partial fast. If you are embarking on a 3-day fast, I recommend reading this article to learn about the benefits and best strategies. I only recommend 3-day water fasts if you are already experienced with and do well on longer intermittent fasting strategies.
If you are not yet physically or mentally ready for a 3-day fast, a partial fast is a fantastic alternative. You may choose to do a 3-day green juice fast, as explained here, or a bone broth fast, as discussed here. Make sure to follow an immune-supporting, nutrient-dense diet as well as immune-supporting lifestyle strategies after your fast (33).
Final Thoughts on Immune Support
As we are facing the COVID-19 pandemic, dealing with flu season, and experiencing a stressful time in our world, immune support strategies are becoming more important than ever before. Follow my top 12 immune support strategies to prevent illness and to protect your health.
The Gut Health Roundtable
Here’s the truth, in this unprecedented and frightening time, there are a few powerful things you CAN do. One of the most important is supporting your body’s BUILT-IN immune system.
Is your gut a battlefield? Yes, and you may not be winning.
Yes, the human body is a healing machine. It is designed that way. But with today’s ever-increasing level of toxicity and stress, your gut is constantly under attack.
And with EIGHTY percent of your immunity living in your gut, that’s an immediate beginning. Your gut is your 1st response zone – before the virus hits your family and IF it hits your family.
There is a one-cell thick layer of gut lining that protects your body from toxins, bacteria, undigested food particles and things we have to google, like lipopolysaccharides … and of course… viruses.
And that gut lining? It replaces itself every 7-10 days (sometimes sooner).
So you CAN impact your health … and quickly.
