Myths And Facts About Boosting Your Immune System

Boosting your immune system is one of the key strategies for safeguarding your health, aging more gracefully, and preventing chronic illnesses.

While there is a lot of faulty health advice out there (much of it not based on science or fact) in this blog we’ll bust a few myths. We will share what we know from the most recent science and clinical trials as functional nutritionists in Tulsa, OK.

Let’s look at a few of the most common myths and truths about your immune system, what you need to do to stay healthy all year round, and what to avoid.

1: Eating more fruits and vegetables can keep your immune system strong

Fact. It is not simply an old wive’s tale that eating your fruits and veggies will keep you strong. Studies have shown that people who eat them regularly tend to be healthier than those who do not. They offer a range of nutrients that can help your immune system fight viruses and bacteria.

Try to eat organic fruit and vegetables of all the colors of the rainbow every day. This way, you can ensure you’re consuming a variety of antioxidants and phytochemicals, or plant-based nutrients, to fight off disease.

2: Vitamins and supplements can help ward off illness and make you feel better faster

This is partly true. A good daily multivitamin can help fill in any gaps in an otherwise healthy diet. However, you can’t supplement your way out of a poor diet. Supplements can, however, help with nutritional deficiencies, but this only works if you have high-quality supplements. Use only medical-grade supplementations that are third-party tested and vetted by medical professionals. Discount and even health food store vitamins don’t always contain what they promise and there is no way to vet the quality.

We suggest supplementing under the guidance of a practitioner who is trained in functional or integrative medicine. They give guidance on the proper supplements based on your actual nutritional deficiencies. They advise you on any interactions, and let you know which vitamins should be taken short-term or which ones are safe to take long-term.

3: Getting enough sleep can boost your immune system

True. There’s a strong link between sleep and a healthy immune system. The main point to remember is that it should be high-quality sleep—that is, deep sleep that offers the body and mind refreshment. During deep sleep, BDNF or brain-derived neurotrophic factor is naturally released which regenerates brain cells.

Most studies agree that the average adult needs 8 hours a night. However, recent studies have also shown that sleeping too much can have a negative effect on your health.

Occasional insomnia should not be an issue, but if it becomes chronic, you should take steps to improve the quality and duration of your sleep. Otherwise, sleep deprivation can make you feel run down, weaken your immune system and lead to cognitive and even gut issues.

Get into a good sleep routine of regular bedtimes and rising times, and see what a difference it can make to your health.

4: Covering your mouth when you cough can keep germs at bay

False. This can help you stop the spread of illness, but do little to help you ward off illness unless everyone in your household and immediate environment does the same.

Don’t forget that viruses like cold and flu germs can also survive on a range of surfaces such as doorknobs, phones, countertops and more. Wash your hands often and avoid touching your face. Especially avoid touching your nose, mouth, and eyes while sick and when around sick people.

5: A positive mindset can boost your immune system

True. A good outlook may be good for your health. One study of law students showed that their immune system was directly affected by their thoughts about their studies.

If they felt things were going well, they had a better immune system. As functional nutritionists in Tulsa, OK, we tell our clients it is not just about what we put into our bodies.  Thinking positively is also good for your mental health as well as your physical health. A positive mindset also means positive emotions which can lower internal stress and keep the stress hormone cortisol in check.

Now that you’ve separated myth from fact in relation to your immune system, you can use what you’ve learned to help strengthen your immune system and ward off illness.
