6 Ways to Reduce the Effects of Viruses and Strengthen Your Immune System

POSTED January 8, 2024 IN
“Cover your mouth!” We heard this growing up when you cough or sneeze. During the  COVID-19 pandemic, sneezing or coughing in public is often viewed as someone with the black plague.

Many symptoms such as coughing and sneezing come from viruses, which can disrupt how the body works. The immune system acts as an army to keep that virus from harming the body, which is why you run a fever.  Increased body heat from fevers can inactivate many viruses.[1]

Scientists call viruses microscopic parasites, meaning that viruses are usually much smaller than bacteria and need a host to reproduce and thrive. Otherwise, they cannot survive. [2]

Once a virus infects a cell, it can then direct that cell to create more viruses.[3] In other words, the virus hijacks that cell into a virus-making machine. This continues until the immune system can stop the virus.[4]

Once your body is infected with a virus, modern medicine has no pill or drug that can stop the virus. We’ve all heard the term, “it had to run its course.”

That is why having a strong immune system is so vital to recover from a virus. The immune system is the first and only line of defense against a virus.

COVID-19: Understanding A New Virus

A virus creates a certain illness. For instance, the influenza virus creates the flu.[5] Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the coronavirus that has led to chaos, isolations, and fear.[6]

Coronavirus itself is not new, and many types exist. However, COVID-19 was a new coronavirus because it hadn’t been previously seen in humans.[7]

COVID-19 Affects Everyone Differently

Research has made some observations about how COVID-19 affects people:

  • The risk of developing harmful symptoms from COVID-19 increases for those with chronic, pre-existing health issues.[8]
  • Being obese can increase your risk for being hospitalized with COVID-19.[9]
  • A recent study from Boston University found that people who are deficient in vitamin D have a 54% higher risk of acquiring COVID-19.[10]
  • One in four who had Pfizer Covid jabs experienced unintended immune response[15]

6 Ways to Reduce the Effects of Viruses and Strengthen Your Immune System

While viruses can impact everyone differently, you have plenty of ways to keep your immune system strong and work with your body to help fight viruses.

People with a strong immune system are better equipped to fight viruses and prevent infection. The choices you make every day can go a long way to protect you against COVID-19 and other infections.

  1. Eat immune-supporting foods. What you eat will impact the strength of your immune system. A colorful array of plant foods including leafy and cruciferous vegetables as well as low-sugar fruits provide vitamin C and Zinc and many other nutrient-rich foods to keep your immune system strong.
  2. Maintain your ideal weight. Obesity is a risk factor for COVID-19, regardless of other conditions such as age. Being obese can impact how your lungs function, the body’s immune response, and much more. Consider a keto diet to find and keep your healthy weight.
  3. Exercise regularly. Exercise of moderate-intensity can lower your risk of infections like COVID-19 while supporting the immune system.[13] HIIT training and Burst Training programs give you a powerful full-body workout in under 20 minutes, in the comfort of your own home.
  4. Manage stress. Stress can increase feelings of anxiety or worry, change your sleep patterns, and worsen mental or physical health conditions.[14] All of those things can take their toll on your immune system. Learn 16 ways to lower stress here.
  5. Get great sleep. It’s no coincidence that you get sick more often when you don’t sleep well. Your body can better fight off viruses and other infections with solid, uninterrupted sleep. Aim for eight hours every night. Our Sleep Formula can help you safely fall and stay asleep.
  6. Get the right nutrients. Being low in even one vitamin or mineral, such as vitamin D, may increase your risk of infections such as COVID-19.  Supporting your immune system has never been more critical than during a pandemic like COVID-19. Supplements to consider to boost your immune system are:
  • Zinc +. Deficiencies in this essential mineral can lower the function of the immune system. Ours has 30 mg of highly absorbable zinc as well as other immune-supporting nutrients, all in just one capsule every day.
  • IM Support. We’ve combined top immune-supporting nutrients – including echinacea, elderberry, medicinal mushrooms, and arabinogalactan – in this powerful formula.
  • Vitamin C. The Rolls Royce of vitamin C supplements. We’ve combined this powerful immune-supporting vitamin with citrus bioflavonoids and quercetin, which support vitamin C’s immune-boosting effect.
  • Vitamin D3 + Probiotics. Being low in vitamin D and the healthy gut bacteria we call probiotics can increase your risk of getting sick. Very few foods provide good amounts of these nutrients, which makes this supplement critical for immune health.
