Our immune system is responsible for fighting diseases. A weak immune system can make us more prone to infections and can affect our health in the long run.

Unfortunately, many people unknowingly cling to misconceptions that can harm the immune system.

Today, let’s clear some facts about the immune system to steer you clear of such misleading myths.

1. You Need Lots Of Supplements To Help Support The Immune System

While some people believe supplements can help boost your immunity, others have contradictory opinions.

If you are deficient in vitamins or minerals, supplements can make up for the deficiency and help boost your immune system.

However, if you are a perfectly healthy person, they are pointless.

Many people believe that taking more supplements will help support the immune system even more which is not true.

Consuming more than the prescribed dose of a vitamin or mineral in a day can lead to side effects like constipation, vomiting and even hyperglycemia in case of Vitamin D overdose.

Make sure to stick to your dosing recommendations and take only the supplements your physician prescribes you.

2. Exercising All The Time Will Improve My Immune System

Exercising improves health. Moderate amounts of exercise have also been proven to stimulate our immune systems.

Studies have shown that people who exercise regularly are less susceptible to diseases and have better heart health.

However, intensive exercise has the opposite effect on your immune system.

After vigorous exercise, the body produces hormones that temporarily lower immunity levels. People who do several exercise sessions per day experience post-exercise immune function depression.

This results from increased levels of stress hormones which suppresses the activity of white blood cells.

It is recommended not to overwork your body and practicing moderate exercise sessions will keep your body and immune system healthy.

3. Sleep Has No Connection With The Immune System

Sleep plays a vital role in the proper functioning of your immune system.

Getting enough sleep helps maintain immune system balance and improve your body’s defenses.

When you sleep, your body releases certain hormones called cytokines which fight against infections, stress and inflammation.

When a person suffers from an infection or gets sick, he is advised to get good sleep since cytokine levels increase during sleep.

If you don’t get quality sleep, it can weaken your immune response which in turn can increase your body’s susceptibility to threats and infections.

4. Your Oral Health Has Nothing To Do With Your Immune System

A weak immune system can lead to bad oral health since it fails to keep the bacteria in your mouth in check.

High levels of bad bacteria in your mouth can lead to problems like tooth decay and gum disease.

On the other hand, taking care of your teeth and mouth can help strengthen your immune system and keep out harmful bacteria that would otherwise gain easy access into your body.

Oral probiotics can help increase the population of good bacteria in your mouth and keep a check on the growth of bad bacteria. This also helps build your natural immune defenses.

Smile Brilliant is one of the best oral probiotic brands in the market. Their probiotic supplement is backed up by clinical studies and research. It works on replenishing your oral microbiome and in turn, strengthens your immunity.

5. Losing Weight Is Good For The Immune System

Losing weight in itself isn’t a bad thing. But trying to lose a lot of weight quickly through extremely restrictive eating measures or overexercising can weaken your immunity system.

You can lose weight without compromising on nutrition and keep your immune system healthy.

6. Antibacterial Foods Help Your Immune System

No scientific studies support the theory that antibacterial foods have immunity-boosting properties. That’s why relying on antibacterial foods to cure your diseases instead of proper medicines isn’t recommended.

We can’t say these foods don’t help at all but they shouldn’t be your first line of defense.


If you suffer from specific health problems, consult your physician before taking any immunity-boosting supplements.

If you are unsure how your diet or exercise affects your immune system, take professional advice from a fitness expert.

Remember, your immune system will face the tune if you take drastic measures and shortcuts to get in shape.
