Parents should learn how to have a better immune system to protect their young ones’ health. A healthy, functioning immune system is the key to our well-being. Unfortunately, most of us defend it with drugs that have a range of side effects. The good news is that there are ways to boost your immune system, and they don’t involve medicine. Life Advancer shows you what they are.

How the Immune System Works

An immune system is a connected group of cells, tissues, and organs that protect the body against invading bacteria, parasites, and fungi. The body is an ideal environment for microbes, and it’s the job of the immune system to prevent them from making themselves at home.

When this rather complex system suffers damage, complications result. These include allergies, infections, and illnesses. When they surface, millions of cells within the system will gather to respond to them.

Scientists are still researching the cells which trigger an immune response. They are discovering the ones that destroy infections and tumors. This means making the immune system stronger.

How to Boost Your Immune System with These Natural, Science-Backed Methods

No one wants a cold, cough, or allergy to set in just because of a handshake. It’s vital to keep the immune system ready to fight infections.

Dr. Timothy Mainardi, an immunologist from New York City, recommends lifestyle habits that we can be incorporated into our daily routines.

These are not hard to cultivate and will make a significant difference in our well-being:

1. Keep to a nutrient-packed diet

First of all, ensure that your meals are full of wholesome goodness. It’s a task to prepare well-balanced meals all the time. However, the well-being we get in return for our effort is worth it.

Dr. Mainardi isn’t the only expert who advocates a healthy diet. Harvard Health also suggests that we should eat plenty of fruits and vegetables to keep our immune system at it’s best performance.

2. Exercise Regularly

Dr. Mainardi also supports having a regular workout routine. Exercise does more than keep us slim; it’s also critical for maintaining our immune systems.

A study by the Appalachian State University and the University of North Carolina, published in the British Journal of Sports Medicine covered 1002 adults over 12 weeks. Those who exercised didn’t report illnesses.

Of course, working out alone is boring. Recruiting a workout buddy or joining a fitness class will raise its fun factor.

3. Sleep

The endless rat race may make us prioritize work over shuteye. But there may be ramifications for our health if we do so consistently.



Dr. Mainardi explains that medical residents who worked 100-hour work weeks risked not only contracting diseases but reactivating those they had before. Commonly reactivated infections include the chicken pox and shingles.

4. Washing Hands

Everyone knows that washing our hands is the best way to prevent infections, But we don’t do this very well.

Many of us use antibacterial soaps, but they aren’t good for our immunity in the long run. Dr. Mainardi suggests using regular ones that we’re comfortable with instead. Furthermore, the Food and Drugs Administration (FDA) indicates that ordinary soaps are the only ones that are necessary.

5. Use a Sanitizer

Hand sanitizers are a must have for camping trips, when there aren’t many places where we can stop to wash our hands. Dr. Mainardi recommends Purell, a sanitizer used in hospitals. The Center for Disease Control (CDC) supports this view and advises how to use them correctly.

6. Take Probiotics

Moreover, Dr. Mainardi suggests having the right bacteria in the gut because the wrong ones may prevent the body from fighting infections.

He suggests that fermented foods such as kimchi have healthier bacteria than other foods. Probiotic supplements and recipes that include probiotics work well when to boost the immune system.

7. Take the right supplements

Finally, it’s wise to scrutinize the supplements you’re taking. Vitamin supplements aren’t always necessary because we can get nutrients from our food. Dr. Mainardi suggests that Vitamins A, D, E, and K are dangerous in high doses.

In all, a little common sense is the best answer to how to get the immune system in order. These best practices will strengthen them and ensure your well-being.
