But, let’s say there are many bears coming after you, and they decide to organize to each takes turns chasing you, so that every hour of everyday, you need to run from a bear with little or no break from the stress. In this case, when stress goes on for too long, your system gets depleted. Stress hormones like cortisol that are raised for too long will start to suppress your immune system. While this bear scenario might be far-fetched, for someone who has a lot of work stress, is taking care of sick family members, and is worried about money—it is as if they are running from many bears all the time. Their immune system will get depleted and stop the ability to fight. Then, when a nasty virus like the COVID-19 virus comes along, their body just can’t cope. While the fear response is helpful in the short term, it hurts our immune system in the long term.
Seven Steps to Calm Your Mind and Strengthen Your Immunity
So, what can you do to help calm your mind and strengthen your immunity? While there is no one magic bullet that will take care of it, I have found a regimen my patients can follow which clearly calms their mind and will boost the immune system at the same time:
1. Get Enough Sleep: Sleep is the important time your body and brain clean out and fix things. Not getting enough sleep alone creates a powerful stress response. Good sleep enhances immune function.
2. Exercise and Yoga: When you are running from the bear, you are making and braking down stress hormones. But if you are stressed and not moving your body, the stress hormones will ravage your body, making you feel stressed, and squashing immune function in the process. Yoga is especially beneficial. Practitioners of yoga enjoy its proven ability to both lower stress hormones and prevent the negative immune changes that comes with stress. Whatever exercise you choose, it can be gentle as as you need—any movement will have benefit.
3. Get Into Nature: one of the best ways to soothe your body and jump start your immunity is spending time in the natural world. We co-evolved with nature, and our genetics are made to respond positively to fresh air, trees and plants. Studies clearly show people who spend time in nature breathe in molecules called phytoncides which get into the blood stream to have positive effects throughout the body. People who spend time in nature see decreases in psychological stress while enjoying simultaneous boosts in immune cells called natural killer cells.
4. Work with a Therapist and Think Positively: one of the reasons the stress response can be chronic is because thoughts in our head can habitually keep going and going, without stopping. What we are telling ourselves (like “ I am not competent” or “life is a struggle”) can keep the bears coming. The thoughts we create in the thought center of our brain (called the prefrontal cortex) tells the stress center of our brain (called the amygdala) to create a stress response. And this has been shown in research—for example, a study of 124 first year law students clearly showed that just having optimism about their school had positive changes in the immune system’s ability to work. Talking to a therapist about your stress and using techniques like cognitive behavioral therapy (CBT) are proven to stop that cycle, and calm the stress response while foster positive thinking. This change in thought will help the immune system remain function at full competence.
5. Eat Healthy Food: a very recent trial showed conclusively what your grandmother already knows—when you eat healthy foods your brain works better and there is less chance of anxiety and depression.  Studies on eating a Mediterranean Diet (little meat, some fish, lots of vegetables and healthy olive oil) also show people will have less anxiety. and will lower inflammation, allowing an optimal immune response when needed.
6. Meditate: whether it is meditation, or some kind of relaxation work, it is important to send a signal to your body every day that there isn’t a bear coming at you and that you are in a safe place. Studies in mindfulness meditation not only calms the body, but is being shown to lower inflammation, strengthen immune response, and even decrease cell and immune aging.
7. Take the Right Supplements: When you take a supplement, you are taking in a natural substance like an oil or plant to help stimulate your body to heal. Here are three natural supports that can both increase immunity and help lower stress response at the same time:
- Ashwaganda: This is an herb from Ayurvedic medicine known for thousands of years for its ability to bring vitality to the body. It is also known for its ability to raise GABA (gamma amino butyric acid), a calming neurotransmitter in the brain, as well as stop immunosuppression. Please visit my past post on this herb.
- Fish oil: Fish oils directly support nervous system and immune function by helping to build the cell membranes nerve and immune cells need to function their best. One study on medical students showed how fish oil can help lower anxiety and balance the immune system by lowering inflammation.
- Melissa officinialis: This is an herb well-known by botanical medicine practitioners. It serves as both a soothing and immune-enhancing plant. Studies have shown how it possesses potent immune refreshing activities. A trial on patients with chronic angina has even shown how it can help significantly promote sleep, lower anxiety and stress response, and even decrease depression in those patients.
The mind is very powerful and can either enhance immune function or stop it from working properly. Fortunately, there are many natural ways to help send signals to shift both your mind and immune power to help you feel less stressed, and create a better immune system.
