Science-backed tips for optimizing you, your family’s immune system

Science-backed tips for optimizing you, your family’s immune system


Immune system – With most schools back to seminormal operations across the country — that is, in-person classes with standard COVID-19 precautions) — families have to think about how to keep everyone safe at home and in their respective day-time environments.


Ways to optimize your own immune system and your kids’.



1. Follow local public health guidelines

First and foremost, keep up with standard COVID-19 precautions.

Your community has guidelines in place for a reason; and following them will help you keep yourself and your kids — and others — as healthy as possible.


2. Get your vaccine as soon as possible

The best way to avoid contracting COVID-19 is to get vaccinated against the disease.

With vaccine doses now widely available; this is one simple step you can take to protect yourself and your family.


3. Make sure your kids are up-to-date on routine vaccines

Children under the age of 16 aren’t yet cleared to get the COVID-19 vaccine; but as a parent, you can make sure they’re current on all of their other routine vaccinations, including the flu shot.

This ensures their immunity isn’t compromised due to the presence of another pathogen.


4. Continue with regular health appointments

Dr. Emily Hu, chief medical officer at Evernow, says she’s dismayed at how many people decided to forgo regular health appointments and check-ups during the pandemic.

She and her children kept up with their normal appointments, and because of that, Hu feels she was able to keep her family as healthy as possible.

If you haven’t had a physical in over a year, now may be the time to do so.

Yearly physicals are the best way to catch early signs of disease and adjust your lifestyle or medications accordingly.


5. Get outside daily

You probably already know that vitamin D is important for your overall health.

Vitamin D profoundly affects your immune function, and evidence shows that low vitamin D is linked to an increased risk for COVID-19; says Dr. Alexandra Kreps, primary care physician for Mount Sinai Doctors at HealthQuarters and assistant professor at Mount Sinai Health System.


Evidence is patchy, but the connection is strong enough to warrant a daily dose of sunshine.


Supplementing with vitamin D is a different story, and research is conflicting. Some studies say high doses of vitamin D don’t seem to have a protective effect or any impact on severe COVID-19, while others suggest they do.

For now, getting some fresh air certainly can’t hurt.

6. Daily physical activity

Exercise is one super simple thing you can do to enhance the functioning of your immune system.

It doesn’t have to be structured or boring — get outside with your kids for a round of kickball or go on a family walk.

Just 30 minutes of light activity each day can make a big difference.


7. Get enough sleep

“There are some fairly simple things that you (and your kids) can do to keep your immune system in its best shape,” says Dr. Kim Boyd, HealthQuarters medical advisor.

“To start, getting adequate sleep is very important for optimal immune function.

Studies have shown that people who don’t get adequate sleep are more likely to get sick after being exposed to a virus.”


8. Address stress levels

Stress increases the body’s hormone cortisol.

High levels of cortisol over time impair our immune response, Boyd says. “Interestingly, the immune implications of stress go beyond just an increased likelihood of becoming ill,” she says.

Prolonged stress also impacts your ability to develop antibodies after getting a vaccination, according to several studies.

“The good news is that stress-reducing interventions that anyone can do, even youngsters, have been shown to help immunity,” she adds.

Techniques like basic mindfulness, meditation, journaling and making time for rest can all help.




9. Minimize sugar intake

Sugar is an inflammatory agent. Reducing your sugar intake; and that of your kids can reduce overall inflammation, Kreps says, thus improving general health.

Chronic overconsumption of sugar can lead to chronic low-grade inflammation; which leads to a number of diseases.

Not only that, but doctors say eating too much sugar can temporarily weaken your immune system.


10. Evaluate caffeine consumption

If you overdo it on the caffeine, you might be unknowingly impairing your immune system.

Caffeine raises cortisol levels, and prolonged cortisol imbalances can negatively affect your immune system.

mild amount of caffeine can actually benefit your immunity; and drinks like tea and coffee contain high amounts of antioxidants.

Just remember, too much of a good thing can turn into a bad thing.
