How to Prevent the Cold & Flu Naturally
We are in the middle of the peak of flu season, and I’ve received several questions in The Myers Way® Facebook Community about how to prevent the cold and flu and stay well this winter. This is an important question as avoiding the cold and flu is vital to limit the stress on your immune system or risk a flare up of other chronic illnesses.
Getting a cold or the flu can also often lead to taking antibiotics which can damage your gut. Antibiotics work by blocking bacterial processes. They either kill the bacteria or stop them from multiplying. Unfortunately, antibiotics cannot tell the difference between the “bad” bacteria causing an infection and the “good” bacteria that belongs in your gut. It’s the beginning of a bad relationship between antibiotics and gut health.
Before we get into tips for natural cold and flu prevention and supporting your immune system during the cold winter months, let’s take a look at the differences between a cold and the flu.
The Difference Between a Cold and the Flu
It’s important to understand that both the flu and the cold are respiratory illnesses, but are often caused by different types of viruses.1 The symptoms are very similar and it can be difficult to tell the difference between a cold and the flu, or even Covid-19. However the one key difference between the cold and the flu is the severity and how quickly symptoms occur.
Flu symptoms are usually abrupt, meaning that one day you may feel healthy and the next day you feel awful. Flu symptoms are usually accompanied by a fever and body aches, which are rare or mild with the common cold.2 Flu symptoms can include:
- A dry, hacking cough
- Moderate to high fever
- Sore throat
- Severe body aches
- Stuffy and runny nose
- Severe fatigue
- Nausea and vomiting
In contrast, cold symptoms will gradually onset and are milder. It is rare to have a fever or chills. If you have a cold, you are more likely to have a runny or stuffy nose. Common cold symptoms include:
- Sore throat
- Headache or mild body aches
- Mild fatigue
Now that you understand the difference between cold and flu symptoms, which is critical for cold and flu prevention, here are my top 10 tips for natural ways you can support your immune system through cold and the flu season
Wash Your Hands Frequently and Thoroughly
The number one way to prevent the flu and other respiratory infections is to wash your hands frequently. The good news is that more people are washing their hands more than ever due to the Covid-19 pandemic.
You should scrub your hands thoroughly with soap and water for at least 20 seconds in order to kill viruses. Cold and warm water are equally effective in killing germs.3 Twenty seconds is about how long it takes to sing the ABC’s one time through. Avoid touching your eyes, nose, or mouth without washing your hands first.
Repair Your Gut
Your gut is the foundation of your whole body’s health because 80% of your immune system is located there. Without a healthy gut, you can’t have a healthy immune system. Without a healthy immune system, you’re open to infections, viruses such as the cold and flu, inflammation, and autoimmune disease.
Therefore, it is critical to reestablish a healthy balance of beneficial bacteria in your gut to prevent the cold and flu.
When we are in optimal health, we live symbiotically with the bacteria in our bodies. If balanced, they promote optimal digestion and immunity, both of which are crucial to every aspect of your overall health and wellness. Taking a probiotic supports an optimal balance of synergistic bacteria to optimize your digestive health.
Reduce Sugar and Alcohol Consumption
You may have indulged in some sweets and a few cocktails during the holiday season. Now that the holidays are over, and the cold and flu season rages on, it’s a good time to cut back the sugar and alcohol to optimize your immune system function and prevent the cold and flu.
Consuming too much sugar can suppress your immune system and make it more difficult for your body to fight off infections, including the flu virus. It also leaves you open to gut infections such as Candida and SIBO, which suppress your immune system and cause leaky gut. Even moderate alcohol consumption suppresses your central nervous system, and therefore your immune system.
Reduce Your Stress
As I mentioned earlier, 80% of your immune system is found in your gut! So what does that have to do with reducing your stress? Stress can make your intestinal barrier weaker and allow gut bacteria to enter the body and create an imbalance between good and bad bacteria.4 Your immune system takes care of most of these bacteria, however that means that it’s constantly in overdrive which can lead to chronic illness and even autoimmunity.
There are many ways to reduce stress to prevent cold and flu, including meditation, yoga, or acupuncture. Some of my favorite ways to relieve stress include getting in my infrared sauna; going on a hike with my husband, my daughter Elle, and our dogs; or taking a relaxing bath with homemade bath salts.
Get Optimal Sleep Every Night
Studies show that people who don’t get enough sleep are more likely to get a cold or the flu. This is because sleep deprivation lowers the body’s production of cytokines, which are essential to fighting off infection and inflammation. They also aid in your body’s response to stress.5
- Eat foods rich in tryptophan and magnesium
- Eliminate fatty foods, heavy metals, caffeine and alcohol
- Get tired naturally by establishing a regular sleep schedule and creating a bedtime routine, exercise, and by using herbal supplements.
If you’re looking for a place to start, I recommend Rest and Restore Max™, a physician-formulated combination of melatonin, valerian root, and targeted amino acids and minerals designed to support deep relaxation and a healthy night’s rest.
Get Plenty of Exercise
Exercise can boost your immune system by increasing your blood circulation. Increased circulation allows antibodies to travel throughout your bloodstream faster, making it easier for your immune system to fight off viruses and infections. Exercise can also support your immune system by relieving stress and slowing the release of stress hormones in the body.
I’ve been doing a lot of at-home workouts I find on YouTube, swimming in my lap pool, and doing yoga and bodyweight workouts.
Support Your Inflammatory Response
Antioxidants are very important for your immune function. Glutathione is the chief antioxidant in your body, responsible for enhancing your immune system and helping your liver with detoxification.
Curcimin is a compound found in turmic that fights free radicals in the body to support its inflammatory response. As great as curcumin is for you, there are a couple factors to consider when determining how best to consume it:
- Turmeric is not easily absorbed by your body. 7 Research has shown that only 1% is absorbed through the digestive system.
- You’d have to eat two pounds of turmeric root to reap the full benefits of curcumin that clinical trials have demonstrated.
- Most turmeric supplements contain very little curcumin.
That’s why I formulated my own curcumin supplement. Liposomal Curcumin provides hundreds of times more bioavailable curcumin than many turmeric based supplements.
Drink Bone Broth
You probably remember your mother or grandmother giving you chicken soup when you were sick, and how it always seemed to help you feel better. It’s not just folklore! Bone broth is actually extremely beneficial for your immune system. In fact, a study published in the journal Chest showed that eating chicken soup during a respiratory infection reduced upper respiratory symptoms, as well as the number of white blood cells (the immune cells responsible for cold and flu symptoms). These benefits are thought to be from bone broth’s ability to reduce inflammation, thanks to amino acids such as proline and glycine. 8
You can make your own bone broth at home by using chicken or turkey bones and vegetable scraps and simply boiling them for about 8 hours (a slow-cooker comes in handy here). Or, if you want the benefits of bone broth without the messy cleanup, try Chicken Bone Broth Collagen or Beef Bone Broth Collagen.
Both are a delicious, savory collagen bone broth sourced from USDA certified organic chickens or grass-fed cows. When mixed with hot water, it instantly creates a delicious, healthful sipping broth that supports whole-body health.
Support Your Immune System
As a functional medicine practitioner and a medical doctor, I know how important it is to support your immune system function. Supporting your immune system is dependent on supplying your body with all the vitamins, minerals, and phytonutrients it needs.
These days, added stress and environmental toxins mean our bodies require more immune-supporting nutrients than ever before. And to make matters more complicated, many of those same immune-supporting nutrients are incredibly difficult to get from diet alone.
Supporting your immune system, strengthening your gut health, and remaining rested and stress-free are not only the keys to preventing the cold and flu, but they also are an integral part of The Myers Way®, and will keep you on the path to optimal health.
