Stay Healthy During COVID With These 6 Immune System Boosters

Even if we’ve been lucky enough to avoid the worst consequences of the pandemic, life has  gotten harder. Many of us simply never expected to homeschool our kids and take care of our  older family members all while pulling 12-hour remote workdays… but to our own shock, we’re  doing it. And that means we need to stay healthy.

So how do we take care of ourselves first so we can be well enough to care for others? One big  piece of the puzzle involves tending to your psychological health, says Dr. KaMala Thomas,  clinical health psychologist and psychoneuroimmunology specialist at Orange County Health  Psychologists. “We know that uncontrolled stress can really do damage to the immune system  through inflammation and increased susceptibility to colds and viruses,” says Thomas.

What you eat can boost your immune system, too. Studies show that foods and supplements  that contain certain vitamins and minerals can help lower your risk of illness and fight infection.

Below are some of the best natural immune-boosting strategies. But just to be clear: While  these tips can help your immune system function at its best, there is no way to prevent COVID-19 other than social distancing and other hygienic precautions recommended by the CDC.

1. Reduce fear and anxiety

We all experience fear and anxiety at one time or another — and our bodies are prepared to  deal with it. The problem is when fear and anxiety linger.

Our natural physiological response to fear (known as “fight, flight, or freeze”) is designed for  short-term stressors. But when stress becomes chronic, that response remains activated, which  can then be harmful, according to research. So what can we do about it?

“If you can control stress, this will have a positive impact on the immune system,” says Thomas.  One study even suggests that happier people have better immune function. Of course, the  advice to “just be happy” can feel like it’s easier said than done.

First, try therapy to examine stressful issues and improve your life satisfaction. Our providers at  Orange County Health Psychologists offer many types of treatment, from cognitive behavioral  therapy to integrative approaches that include powerful evidence-based techniques such as  EMDR.

Meditation, or the practice of focusing on the present moment, can also improve mental clarity  and promote calm. In fact, more than 200 studies have proven that mindfulness-based  therapies, which include meditation, reduce anxiety.

2. Improve your relationships

Those of us who feel lonely may also have lower immune function, says the APA. Like anxiety,  loneliness prolongs the fight-or-flight stress response that ends up weakening the immune  system.

To combat loneliness, especially during the pandemic, remember that “social distancing” really  just means physical distancing. Make an extra effort to reach out to loved ones you’ve lost touch  with over email, text, or Zoom. Online groups, such as on Facebook or other social media, also  make it easy to get together with others around a common interest. You might even think about scheduling regular outdoor meetings with friends or going for walks in the park or around the  neighborhood. And remember, you can also get support via online counseling right from your  home.

3. Laugh more

Yup, you read that right. Laughter has been shown to decrease the presence of stress  hormones like adrenaline and cortisol. And as we already know, controlling stress is key to  improving our immune system.

Not only that, but laughter can promote the function of immune cells and antibodies. While  sources such as Harvard Medical School claim the increased risk of COVID-19 in those over 65  is due to a decrease in T cells, laughter has been shown to increase T cells. T cells are one of  the main components of the immune system that help us fight off viral infection.

So, don’t wait — it’s time to have some fun! Get the family together and watch funny movies.  Spend more time playing with your kids or grandkids. Take regular breaks and find things that  make you giggle.

4. Focus on good nutrition

Overall, eating a balanced diet boosts your immune system health — but specific amino acids  found in protein will especially help your T-cell function. Foods with lots of protein include meats,  poultry, seafood, eggs, beans, nuts, and seeds.

What’s more, research shows that having low levels of vitamin D can increase susceptibility to  upper respiratory tract infection as well as influenza. If you think you might be vitamin D  deficient, one of the best sources of vitamin D is fatty fish, such as trout, salmon, tuna, and  mackerel.

Zinc can also shorten the duration of colds by up to 40% depending on the dosage and what it’s  combined with. One study also claims it can reduce risk or shorten the duration of  coronaviruses. If you want to add more zinc to your diet, you can take it as a supplement or look  for it in oysters, lean meats, fish and seafood, whole grains, beans, nuts, and seeds.

Finally, if you need more ideas or a customized nutrition plan to help you meet your mental  health goals, be sure to see one of our nutritional psychologists: Susan McIntyre, LMFT or Dr.  Desiree Delagarza.

5. Exercise

Regular exercise has so many benefits, so it’s no surprise that it can help boost your immune  system. Not only will it help your immune response, but according to one scientific review, it can  also lower your illness risk.

According to the U.S. Department of Health, healthy adults need 150 minutes of moderate  aerobic activity per week (or if you exercise moderately to vigorously, then 75 minutes).  Obviously, this is hard during a pandemic when most of your day may consist of sitting at home  working! But our bodies’ needs haven’t changed, so if you want to stay healthy, you must get  moving.

By comparison, kids aged 3 to 5 should be physically active on and off throughout the day, and  those aged 6 to 17 should get 60 minutes of moderate-to-vigorous exercise per day, says the  American Heart Association. If it’s tough to inspire them to get off their screens, try scheduling a  daily walk, socially-distanced hike, or even a family living room dance party to get those hearts  pumping!

6. Get better sleep

Did you know you could be more likely to catch a cold if you sleep less than six hours a night as  an adult? To support your immune system, be sure to get the recommended amount of sleep for  your age. Generally, adults should get 7 to 9 hours per night, teens need 8 to 10 hours, and  children under age 14 need more than 10 hours.

There are many ways you can improve your sleep. The National Sleep Foundation shares some  great ideas, including keeping the room temperature at around 65 degrees (it helps signal to  your body that it’s time for sleep) and exposing yourself to natural light (or a lightbox) early in  the morning to regulate your circadian rhythm. And if you want to track your sleep in addition to  getting better rest, an app might help — check out the ones we reviewed in this post (scroll  down to “Apps for Sleep”).
