Thinking Outside the COVID-19 Box: 10 Ways to Boost Immune Function

Over the past 18 months, I’ve heard a lot about masking, hand washing, and social distancing to protect yourself and others from coronavirus. Sadly, I’ve also heard about many immunocompromised people dying from the virus. But I haven’t heard top health officials talk much about boosting immune function. Have you? Doesn’t it make sense that we should all be working to strengthen our immune systems now more than ever?

Immunity is our first line of defense, meaning, more than anything else, it works to keep us healthy regardless of what’s going on around us. But it’s up to each of us to provide this mighty defender with good fuel and take other beneficial steps to enhance its efforts. You will find below 10 of my best ideas to accomplish just that.

  • Hydrate, hydrate, hydrate. In addition to drinking plenty of mineralized water, eat lots of (home-cooked & organic, if possible) soups, suggests Gina Bria, co-author of Quench: Beat Fatigue, Drop Weight, and Heal Your Body Through the New Science of Optimum Hydration. Also, I’ve read from many sources, daily green smoothies with (organic if possible) fruits and veggies are deeply hydrating, as well as nutrient-rich. Think apples, oranges, pears, mangoes, grapes, blueberries, avocados, celery, cucumbers, sprouts, cilantro, Italian parsley, spinach, red leaf kale, spirulina, cinnamon, cardamom, fresh ginger, chia seeds, and turmeric with fresh-ground pepper. (Shoot for using more veggies than fruits.) Any combination is tasty, and will gift your body with perfect, structured plant water. Anthony William, the New York Times Bestselling Author of Liver Rescue, says your hydration level (or lack thereof) can be a pivotal factor between getting sick and staying healthy.

  • Exercise moderately several times a week. A study published in the British Journal of Sports Medicine found that participants who did aerobic exercise 5 days a week reduced upper respiratory tract infections over a 12-week period by 43%. Exercises in that category include brisk walking, running, cycling, swimming, and other cardio pursuits sustained for an extended period. An article on states exercise helps highly specialized immune cells—such as natural killer cells and T cells—find pathogens (like viruses) and wipe them out.
  • Consume natural probiotic food & drinks such as (organic & raw, if possible) kombucha, sauerkraut, kimchi, and miso soup. Stanford University of Medicine researchers Justin & Erica Sonnenburg, PhDs, say their family gets a different natural probiotic food or drink each day to diversify the population in their microbiomes as well as those of their kids. Studies show that diversity in the gut is a major key to staying healthy.

  • Eat fewer pre-processed foods, including fast foods and junk foods, and more high-fiber whole vegetables, including beans and lentils, as well as prebiotic foods such as onions, garlic, dandelion greens, and asparagus. Again, all in service of a microbiome that can promote good immunity.
  • One more tip for the microbiome, from Dr. Zach Bush, a physician specializing in internal medicine, endocrinology and hospice care. A healthy microbiome, according to Dr. Bush, consists of between 20,000 and 40,000 species of bacteria. (Which explains why you should not eat the same foods all the time.) Spending time outside and in multiple ecosystems (for example, a rainforest, beach, desert, waterfall, lake, and river) can diversify your gut’s bacteria. And, if you’re far enough away from others, take off your mask! (Unless that is prohibited in your area.)

  • Diffuse essential oils inside your home, which is the next best thing to being outside. Dr. Josh Axe, Certified Doctor of Natural Medicine, says that many essential oils are antibacterial, anti-fungal, and antiseptic. He suggests eucalyptus, peppermint, oregano, lemon, and cinnamon for immunity. Add a few drops of some or all of them to your diffuser, vaporizer, or humidifier, if it offers that function, to purify the inside air that you breathe.
  • Even though you are practicing social distancing, make emotional connections. Phone or text a loved one, just to check in. According to Dr. Dean Ornish, Clinical Professor of Medicine at the University of California, San Francisco, those societies and cultures over the past several hundred thousand years who learned to take care of each other were more likely to survive than those who did not. Our species has a primal need to feel cared for.
  • Practice expressing gratitude for your life and your blessings. Your feelings and beliefs have a strong impact on your biology, according to Gregg Braden, 2020 Templeton Prize Nominee. Your cells are always listening in on your thoughts, Braden says. Therefore, immune function is directly affected by your state of mind.

  • Take a break from watching or reading the news. Non-stop negative reports about the pandemic, environmental degradation, violence, dirty politics, etc., can result in a fearful mindset, constantly activating the fight-or-flight mode in our bodies. This can result in biological conditions that suppress immune function. Check in on the news only once or twice a day, or maybe even skip a day (unless you feel more anxious as a result.) Instead of spending so much time sitting on the sofa watching or reading the news, get outside to walk, do some yoga, or other enjoyable activity. (Since exercise and time in Nature are also good for immune function, this one idea offers three times the benes for your hard-working immune system!)
  • And finally, get enough sleep that you awake feeling rested. With so much ongoing illness around us, our biological functions may be working harder than usual to keep us well. You may find your need for sleep has increased. Listen to your body.

I hope this list empowers you to become healthier and diminishes your fears of the virus. It is important to continue following the many protocols in place. But it is also critical, in my opinion, to do all you can to boost immune function at this time when illness abounds.

Blessings for Immunity,

  1. Nice work Lisa. I have been looking at the science of crystallography within our DNA structure. It’s being developed by the Dept of Molecular Biology, Science and Technology at Nara Institute of Science, Japan. Perhaps, you’ll have the time to research and write about crystallography too as I find it’s esoteric origins lie within Yoga? But Im no expert.

    1. Hi, Alec, thank you for reading & commenting. I can’t say that I’ve heard of DNA crystallography. Maybe if you wrote a post on it, sharing some of what you’ve been learning, I would be inspired to learn more! Have a great weekend! 🌞


    1. 💜 Red Wine and Laziness Works (pun intended) too EveryOne; in The Mediterranean and Nearby Territory Drinking Red Wine ALL Day (in the absence of driving and operating dangerous machinery of course) along with Siesta ARE a Way of Life and increase Longevity…there is a Peculiar Preoccupation in The ‘First’ World with Creating Stress and Pressure via UnNecessary ‘Work’ and Trivial Tràváìl; as Spock puts it, “Fascinating”

  2. An excellent list – especially the one on tuning out the news. Note I have found it interesting to really understand the word moderate in the context of “exercise moderately”. Due to my aggressive hobbies (which you are aware of) I’ve always been intrigued by the science on too much exercise and the effects on immunity, cell regen etc. and it is all over the board from what I can tell even to the point of banding (exercise for this amount okay, go beyond that into the next band and its is bad, but then go past that and it is good from adaptive purposes). Regardless, totally with you with regards to building up our own immunity.

    1. Hi, Cindy! I am grateful for your kind comment. I’ve read a lot about coffee, some really good stuff and some really bad, so I’m not sure where I stand on it. As for cookies, if they’re made with all good stuff & no dairy or high fructose corn syrup, I’d say they’re good for the gut’s microbiome! Have a beautiful week, my friend! 🌞

  5. Such a powerful, insightful, and loving post, dear Lisa. I adore this post, and agree wholeheartedly with all of your suggestions. The last couple are particularly impactful, I think, such as taking care of ourselves emotionally, getting enough sleep, turning off the tech…so true. Have a lovely week! 🤗

  6. I am becoming lazier day by day. Thanks to the university for opening the campus for the students.

    I’m attending online classes, can’t join offline. I need regular exercise and a light daily schedule.

    Hoping to write some amazing posts for you. Take care. 😊👍

  7. Lisa, though this post was written some time ago, it still gives good advice. I am grateful for the vaccine I received, but with breakthrough infections and varients, I have put my mask back on. The advice on hydration, nutrition, and exercise is good advice in any era. ❤ all the best!

  8. Fantastic post! I don’t know why almost nobody is talking about this. Boosting the immune system is important and be done without any harsh side effects. Less stressing, less fear, more sleep, more taking care of ourselves. So important to get this across for now and into the future. We don’t do enough in this world to teach people about proper holistic health. Love your approach here!
