Great Tips for Avoiding COVID-19 (The Coronavirus)


Here is our article previously titled "How to Never Get the Flu Again." We thought it would be very timely to feature it again, considering these are great tips for avoiding any virus, including COVID-19. 

As a young person, I was frequently sick. I remember that familiar feeling of the sore throat that inevitably led to the same symptoms three to four times every single year. Each time the seasons changed, my health would take a dive and I would be out of commission for about a week, sometimes with a cough that lingered for a month or more. Sometimes I would just get what we would call a “head cold.” That meant I would get the upper respiratory problems of a runny nose, sore throat, watery eyes, ear aches, and a cough.  Sometimes I would get a fever, body aches, diarrhea and vomiting. This we would call a flu. Often there would be a combination of the two or one would lead to the other. The point is, I was miserable and sick and tired of being sick and tired so often. So around the age of 19, I decided to start reading up on how to strengthen my immune system.  Fortunately, this was also around the same time that I decided to give up eating all animal products, also due to a great deal of reading about health. 

The problem in seeking health information is that everyone has a theory, some based on real science and some not. Some of the science is even not so good. I had to wade through a lot of conflicting information and read a lot of heavy science. There are tons of books, and now websites full of well-meaning advice on how to boost the immune system. Some of the tips I picked up worked, and many did not. But after a short time of putting forth real effort, I managed to keep myself flu-free—for a season, a year, and now, whoo hoo, it’s been 26 years since I have had anything resembling a flu. I have had occasional head colds over the years, but they are very rare now—maybe one every 5 years or so. And, they only occur when I neglect doing the things I have listed below.  This list is a compilation of the things that I have learned work well for boosting the immune system, after many years of study and personal experimentation. I have shared these tips with friends and have successfully kept many others free from sickness for extremely long periods of time also.  Now you can benefit from them too.

  1. Eat an all plant-based diet. Many flu viruses come from poultry, egg (bird flu), pig (swine flu) and other animal farms. The viruses are zoonotic and even if you intend to cook it well, the products from these farms will contaminate your kitchen before you get a chance to fire up the range.

  1. Eat all organic. Pesticides work by breaking down the immune systems of pests. GMOs are widely believed to harm the consumer in many ways. This is backed up by numerous large scientific studies, and that is why many countries have banned them.

  1. Get at least 8 hours of sleep every night. If you work out hard or are dealing with stress, you may need 9 hours. Your body does most of its healing while you are asleep. Give it time to do its job.

(Opp, Mark R., and James M. Krueger. "Sleep and immunity: A growing field with clinical impact." Brain, behavior, and immunity 47 (2015): 1.

  1. Stay warm and moist. It is especially important to keep your torso, head and throat warm. The rhino virus needs your throat temperature to drop below 90 degrees F/ 32 C to replicate. For this reason, I will wear a scarf all day and even to sleep at night when it is chilly and my throat temperature is at risk of dropping below 90 F. Moisturize the insides of your nostrils and ears. When it is cold out, it is also dry. Viruses enter the body through the nose and can enter the bloodstream easily if there are little cracks in your nasal passages. You will also prevent ear aches from the dry air if you moisturize the ear canal. Olive oil or coconut oil are good, natural options that are also anti-viral, anti-fungal and full of antioxidants.

  1. Things to eat more of: onions and garlic, citrus fruits, apples, leafy greens, cherries, blueberries, pineapple, and seaweed. This is not a complete list, but these are items I found to be especially helpful when germs are flying. However, make sure to eat a wide variety of many colors from the produce department, and, avoid processed foods as much as possible.

  1. Put a drop of organic pure oregano oil in your water bottle and drink lots of that water. Hydration is key in beating illness since it gives the body an easy way to eliminate toxins through urine. And oregano oil contains powerful anti-viral, anti-inflammatory, anti-fungal, and antimicrobial properties.

  1. Avoid caffeine. You need to be able to sleep for adequate hours and depth. Caffeine has also been shown to suppress the immune system in many ways.

  1. Avoid alcohol. It depresses the immune system by hurting beneficial gut flora. Healthy gut flora is the key to a strong immune system. Relax with some nice chamomile tea instead of that glass of wine.

  1. Avoid processed sugar. It harms your gut flora while attacking your teeth. However, whole fruit, fruit smoothies, and even a moderate amount of fruit juices provide natural sugars to invigorate the body, combined with loads of antioxidants, vitamins, minerals and electrolytes to hydrate and nourish the body. However, when only the sugar is extracted from a plant and then it is processed with heat and often harsh and unnatural chemicals, it becomes something else all together that harms instead of benefitting the body. The most harmful affect is the spiking of insulin that occurs, giving the body a quick rush of energy. That spike is followed by a fairly quick and hard crash, leaving the body more depleted energetically than before the ingestion of the sugar. That is why nature provides sugars wrapped in a food that contains fiber. The fiber slows the absorption of the sugars, while the plant food also provides needed nutrients for healing and longevity. So while you should avoid processed sugar, as mentioned above in number 5, you should eat plenty of fruit to help boost the immune system.

  1. Don’t get a flu shot. Recent research shows that they do more harm than good.

BONUS:  If you do get sick…

  1. Lemon juice is a natural cough suppressant. If you find yourself in a coughing spell that won’t stop, suck on a fresh lemon and you will be amazed.
  1. Olive oil on a cotton ball inserted into the ear canal instantly stops an earache.
  1. If you get a runny nose or tickle in the throat from post-nasal drip, the best way to get rid of that quickly is to rinse the inside of the nose and throat with saline. This can be done with a neti pot or saline spray.
  1. Do all of the above 10 to boost the immune system for a speedy recovery.
