There is still so much unknown about the coronavirus, but having a healthy, functioning immune system will always be helpful in reducing the effects of the virus, if contracted, and, could possibly be helpful in prevention of even contracting the virus at all.
Here are a few tips on how to strengthen your immune system naturally:
Vitamin C is arguably the most essential nutrient for immune function — it produces white blood cells (the first line of defense against viruses and infections) and gives an overall boost to your body’s immune system. While oranges and other citrus fruits are most commonly associated with vitamin C, there are several surprising foods that are top sources of this essential vitamin.
Sweet potato, butternut squash, mango, papaya, pineapple — basically all orange, yellow and red fruits and veggies will fulfill your daily quota of Vitamin C. A cup of chopped red bell pepper actually contains nearly three times more vitamin C than an orange. Broccoli is another winner — just a half cup of cooked broccoli will fulfill 84% your RDI (Recommended Dietary Intake) of vitamin C. Chestnuts, chili peppers and kiwi are also good sources.
Eucalyptus oil has been used for hundreds of years to treat respiratory problems, but its medicinal uses have been gaining more attention recently in conventional medicine — so much so that you’ll find it in many of the over-the-counter medicines you likely already have in your home.
Eucalyptus oil is a bronchial dilator (increases airflow to the lungs) and is thus used for treating everything from cough, cold, running nose & sore throat, to asthma, nasal congestion, sinusitis & bronchitis. “Its main component is 1,8-cineole, an expectorant & anticatarrhal that reduces mucus production,” explains Gina Flores, Certified Clinical Aromatherapist and instructor in our Continuing Education program at Swedish Institute. “It has amazing anti-bacterial & anti-viral actions, as well as antiseptic & stimulant properties.”
Laurel is another powerful antiseptic aid that Gina recommends for respiratory illnesses due to its high amounts of 1,8 cineole — especially for colds with catarrh & chronic bronchitis.
Clinical studies have indicated that regular massage not only helps alleviate pain and stress, but also increases the activity level of the body’s white blood cells that work to combat viruses.
“Massage therapy has been shown to naturally increase the immune system’s cytotoxic capacity (the activity level of the body’s natural “killer cells”) and decrease the number of T-cells, which improves the body’s immune functioning overall,” explains Ericka Clinton, Dean of Massage Therapy at Swedish Institute. Studies out of Cedars-Sinai* have shown regular massage therapy sessions to have a direct impact on the body’s immune markers — such as increased levels of lymphocyte (one of the three subsets of white blood cells in the immune system which play a large role in defending the body from disease), as well as significantly improved function of NK-cells, which provide rapid responses to viral-infected cells.
From cold-water immersion to frigid air exposure, cryotherapy has been around in one form or another for ages —from Roman frigidariums to modern day ice baths. But sitting in a tub of water chilled to 50° isn’t exactly pleasant for most people.
Enter cryotherapy. Cryotherapy involves short exposure to extreme cold via a cryochamber – a human-sized tank filled with liquid nitrogen-cooled air. You sit or stand for 2-3 minutes as the temp plummets to as low as -300°F. This burst of intense cold triggers the production of a low dose of stress that keeps your cells on their toes. It elicits an adaptive response & activates white cells. Your bolstered immune system can then fight off viruses & disease factors.
A regular exercise routine helps keep your immune system functioning at top levels. Exercise increases blood flow and circulation of immune cells. Exercise also helps to recruit highly specialized immune cells such as natural killer cells and T cells, which find pathogens (like viruses) and wipe them out.** When you’re physically active, you can keep pathogens out of your lungs and airways, minimizing illness.
If you are already doing regular exercise, then keep it up! If not, you can start by walking a couple of times a week and then over time add in more cardio workout and strength training.
Not only is getting the right number of hours of sleep a night important (7-8 hours) but also making sure you are getting quality sleep as well. Studies show that people who do not get quality sleep or enough sleep are more likely to get sick after being exposed to a virus, such as a common cold virus. Lack of sleep can also affect how fast you recover if you do get sick. This is because when you sleep, your body produces protective cytokines that help fight off infectious diseases.
🔵 Break Unhealthy Habits
Smoking and drinking excessive amounts of alcohol can also attribute to having a vulnerable immune system. Studies have shown that excessive alcohol consumption leads to compromised immune systems and an increase in respiratory infections. For example, in the lungs, alcohol damages the immune cells and fine hairs that are supposed to clear pathogens out of our airway.*** According to the U.S. Dietary Guidelines for Americans, alcohol consumption should be up to one drink a day for women or two per day for men.
Similar to drinking alcohol, smoking also damagers the immune system and can weaken the body to fight off diseases. Quitting smoking improves circulation, increases oxygen levels, and lowers inflammation — all of which give your immune system a boost, so it’s easier to fight off colds and other illnesses.
