Five Steps to Reduce Stress, Improve Immunity, and Decrease Your Risk of Coronavirus Infection

Five Steps to Reduce Stress, Improve Immunity, and Decrease Your Risk of Coronavirus Infection

1. Stay socially connected while socially distancing: While social distancing, which means limiting physical contact with others, is important to prevent the spread of the coronavirus, staying socially connected improves immune function and decreases the risk of being infected.

Studies comparing gene expression in lonely people to socially connected people found 209 genes expressed differently. Specifically, in the lonely group, genes that are associated with inflammation were turned on, whereas genes that have antiviral roles were turned off.[1] [2]

Steps to stay socially connected while staying physically apart, would include:

  • Engaging in activities with members of the household, talking and encouraging each other, playing games, doing puzzles—but also actually connecting and showing interest in each other.
  • Talking with friends and family on the phone, via Skype, or FaceTime
  • Creating online groups of friends or family for discussion, sharing, Bible study, and encouragement

2. Get 8 hours of sleep each night: Multiple studies have demonstrated that sleep is essential for healthy immune response. Those who sleep less than 8 hours each night have immune systems that are less responsive to infection, while those who sleep 8 hours each night make antibodies more effectively and are able to fight infections more readily. This is one factor why vaccines are not as effective in every person. Persons with chronic sleep deprivation do not get the same antibody production and subsequent protection from vaccines when compared to subjects who sleep 8 hours each night.[3] [4]

Steps to improve sleep include:

  • Decrease or eliminate stimulants, such as caffeine
  • Do not use alcohol as a sleep aid
  • >Use the night setting on electronic devices to decrease blue light
  • Don’t eat a heavy meal before bedtime
  • >Ensure a comfortable bed and cool sleeping environment
  • Ensure your room is dark
  • Keep animals out of the room and bed
  • Consider a sound machine or fan to create “white noise”
  • Establish a routine and schedule for going to bed and getting up—and stick to it
  • If sleep problems persist, see your doctor
  • Do not take sleep medications unless directed to do so by your doctor

3. Regular moderate aerobic exercise: Studies show that regular moderate to vigorous exercise of no more than 60 minutes enhances multiple immune functions. However, extreme exercise, such as running a marathon causes immune dysfunction. Regular moderate aerobic exercise improves macrophage activity, circulation of immunoglobulins, anti-inflammatory cytokines, neutrophils, and various lymphocytes. These changes improve the body’s immunosurveillance. Moderate “exercise is now viewed as an important immune system adjuvant to stimulate the ongoing exchange of leukocytes between the circulation and tissues” and improves the body’s immune response to vaccination. [5]

Steps to healthy exercise:

  • See your doctor to get a physical exam and start exercise under your doctor’s supervision
  • Begin low and go slow, gradually increasing duration and intensity
  • Choose an exercise you enjoy
  • Exercise outdoors when possible
  • Examples of aerobic exercise include: walking, running, biking, rowing, swimming.
  • The easiest to engage and maintain over time is regular walking—aim for 30–60 minutes a day, 5 days a week

4. Healthy Nutrition: The goal of healthy nutrition would be to move your diet away from foods that increase inflammation and impair immune response toward foods that decrease inflammation and improve immune response. Plant-based diets have been shown to do just that. A meta-analysis of 29 studies found that plant-based diets decreased a host of inflammatory factors and, thereby, decreased disease risk.[6]

Steps to healthy nutrition include:

  • Eat fruits, nuts, vegetables—the more colors the better as the colors are high in anti-inflammatory factors: berries, carrots, yams, spinach, etc.
  • Get your vitamin D level checked by your doctor and take vitamin D supplements to achieve a level of 75–100 nmol/L. Levels below 25 increase all causes of death, and levels above 140 increase all causes of death.[7] Studies show that normal vitamin D levels improve immune response and may reduce risk of infections, particularly viral infections like influenza and corona.[8] [9]
  • Avoid or minimize junk food as such foods are highly inflammatory

5. Laugh: In 2019, I wrote a blog on the benefits of laughter and will recap some of those benefits here.

Mirthful laughter reduces inflammation, improves diabetes control, and reduces incidence of heart attacks.[10] Other researchers found beneficial effects of laughter on the blood vessel. Nitric oxide is a chemical that the body uses to dilate blood vessels; mental stress was shown to degrade nitric oxide. This means that laughter minimizes the negative effects of stress by reducing the breakdown of nitric oxide, leading to vasodilatation and better blood flow.[11] On average, laughter increased blood flow by 22 percent and stress decreased blood flow by 35 percent. [12]

Laughter has been shown to improve the response of the immune system, which is especially important at this time.[13] In a study performed by Berk LS, et al., they found increased blood levels of interferon-gamma (an immune product that fights infections and cancers) in ten healthy fasting males after being shown a comedy video (p=0.02).[14] As a result, interferons have become a line of pharmacotherapy in viral infections, systemic carcinomas, hepatitis B and C, in addition to the development of antiretroviral drugs.

There are two types of stress: distress (the negative type) and eustress (the positive type, which would include mirthful laughter). Distress increases stress hormones—such as beta-endorphins, corticotrophins, and catecholamines—but laughter (a form eustress) decreases these hormones, fortifies activity of natural killer (NK) cells, activates T cells and B cells, and increases Ig levels. This means that laughter is capable of combating the negative aspects of distress and fortifying the immune system to help fight against various immune mediated illnesses.[15]

Steps to laugh:

  • Check out our Reasonette comics
  • Watch non-vulgar comedy programs or stand-up comics
  • Play interactive games like Pictionary or Balderdash
  • Tell jokes to friends or family
  • Choose to see the humor in life

Testimony 33

I was invited over a friend’s house to see the “God and Your Brain” seminar today. I became [a christian] 36 years ago at the age of 19, but have struggled with the concept of God taking His ‘pound of flesh’ out on His Son to be appeased. Wow. Your seminar has been an incredible revelation and breath of reason and fresh air! I have your book, “The God Shaped Brain,” and it is SO eye opening. Finally, after 36 years enlightenment has come! Praise the Good Lord! What can I say, but that the Real Gospel is truly “Good News!” Thank you for your efforts in giving the Gospel a clear sound!

Paul C.,  Springfield, MA, USA

 

Testimony 36

Thank you and may God continue to bless you as you share with others the intricacies of how we are all “fearfully and wonderfully made”. I must share that you have opened a whole new world to me, and I have found tremendous healing through what you have shared in two of your books, “Could It Be This Simple?” and “The God Shaped Brain.” I praise God for what you shared, what I have learned, and how I have grown and healed! My prayer is that My Precious Jesus will be seen by others in the way I live, act, talk, etc. and they may be encouraged to know He is truly a GREAT God of LOVE, desiring that no one should perish! God Bless you in your continued endeavors to present Him as He really is!

Testimony 43

Two years ago I stumbled upon your book, “Could It Be This Simple,” and then found “The God-Shaped Brain” videos on YouTube, your bible study class, and the ‘Come And Reason’ mobile app. I shared your book with a friend and after nine months of showing love, patience, and kindness this person has been changed by the love of God, too. The same love that healed me, I now express to other women in tangible ways, such as to a Baptist woman with high anxiety and childhood trauma. She was extremely happy and relieved when I shared about the so-called “judgment of God” and burning in hell. She had no desire to serve a God that was so harsh. I have repeated the phrase dozens of times to her. “What we believe has power over us, but we have power over what we believe…”

This message that you are sharing has changed my life. I will continue to serve other women and bring this message of God’s healing love to their lives by sharing your books, YouTube videos, and The Remedy Bible app. Keep up the good work. Don’t be discouraged. God is doing a mighty work in and through this ministry!

Testimony 7

Ok, so last night I listened to “The Law of Liberty” and “How to Achieve Victory: Freedom, Truth and Spirtual Warfare.” These are both MY ABSOLUTE FAVORITES so far! The logic is just soooooo beautiful. I had to re-listen to them a couple of times. I just want to EXPLODE! (<< we assume with joy and happiness)

N. B., Canada

 

Testimony 68

Your message of design law vs imperial law is so uplifting and makes so much sense- it is a game changer for me. The fact that Jesus’s death is not a big payment by an angry God is , quite frankly, a relief.

Laura G., London, Ontario, Canada

 

Testimony 48

I just want to tell you how blessed I have been reading “The Remedy!” It has become a daily part of my devotional relationship with God. In it I have found a God of love and a God that loves me! The bible has come alive for me! It is the first time that I can say that I have felt hope fill my heart as I have read God’s word. This is good news I can share! Thank you, Dr Jennings! Thank you for your heart for others. I can’t put into words how this has set me free! It has strengthened my trust and love for God.

Testimony 52

Your unique way in spreading the truth is what we all need today. Most of us don’t recognize the contamination coming from all the lies and selfishness in the world. Because of our fear of death, we forgot how to live. Lies left and right. I was losing hope and faith, because of so many ideas that are always contradicting each other – so many questions answered by other, more complicated, questions – until I found your channel on YouTube.

You did not just give me answers, you also taught me how to answer new questions that arise in my mind. Now I see things differently. I see God’s mercy, grace, and Love everywhere, in spite of all the chaos that we all have done as humans. I don’t fear death anymore. Accepting the Truth and Love about God is truly a genuine Freedom from all the confusions, sufferings, selfishness, pain, and death.

I just wanted to say, thank you, sooooo much for revealing the real Remedy for our infected life. I have a new hope and now see the world in a different perspective!

Wheinny P., University Place, WA, USA

 

Testimony 10

I personally download and listen to each of Come And Reason Ministries Bible study class lessons and PDF study notes to use when teaching my class. Really appreciate the class especially when Dr. Jennings is teaching. Thank God there are persons like him doing His work and traveling to share His beliefs.

B. L.M., North Plains, OR, USA

 

Testimony 19

I truly believe that to know who God really is the first step to understand ourselves in a balanced and kind way, so the healing can take place. Your approach really makes sense – Thank you for your ministry!

A.M., Pittsburg, PA, USA

Testimony 62

I would like to express my thanks to the C&R team for creating a platform from which people can learn to trust in God and grow. My life is a witness to the effectiveness of this ministry. Without believing the truth about God as you have shown, I don’t know what my life would be like. I had given up on God helping me with certain sins – it was all useless. Given that the scripture is clear and God is so good, how could I have betrayed him so many times? I was a yo-yo christian; spinning up and down. My faith and enthusiasm was driven by discoveries/threats that prophecy is about to be fulfilled. But when I watched your “Healing the Mind” seminar, it was like a light finally went on. I could see God had no plan to hurt me, the danger came from sin, and that He is working to protect me and strengthen me. Thank you for allowing God to use you. The message God gave C&R saved my life!

Testimony 67

I was introduced to Come And Reason by a friend of my mother-in-law, who gave me several CD’s of Dr. Jennings. The clarity of the message and recognition that God’s is a God of love was so clear, advancing beyond Dr. Maxwell’s message. However, grappled with Maxwell saying God used emergency measures for the fallen world. Now after several years of being a regular listener of the Come And Reasoning bible study class and attending Jennings’ meetings in Dallas/Fort Worth, TX, things are becoming clearer for me. Design law versus imposed law has added so much to my personal understanding of theology. This message has really impacted my work in counseling so many people miserable because they are searching for and trusting human governments to create order and peace or believing in a God who says love Me or I will kill you. I am grateful that I have an alternative view to offer my clients that makes sense. I teach a bible study class on a semi-regular basis and I value the materials that Come And Reason so freely offers to aid me in presenting this vital message. Thank you for continuing to provide advancement in our very limited understanding of a Infinite God that is rational and believable.

Dr. Roger D, Arlington, TX, USA

 

Testimony 6

I got the book “Could It Be This Simple?” a few months ago and the reading was wonderful and I was fascinated. I lent the book to a friend at work. She is having a difficult time and the book is helping her to find Jesus and I found this very exciting. She has asked me questions and I can see her life changing.

H. S., Australia

 

Testimony 17

The blessings of clarity and understanding you and your class inspire me to take from the word of God have impressed upon me so greatly the true, loving character of our Creator. I have found amazing freedom and joy through building a stronger, more intentional relationship with Him. What is new is that this is now a relationship built on love, reverence and respect rather than fear and obligation, and as such my eyes have been slammed OPEN as I am continually impressed by the manifestations of God’s true character in His provisions for fallen man.

T.E.H., Salt Lake City, UT, USA

 

Testimony 55

I was born [into the church], then I left it for many years. 10 years ago, I came back, but I could not take the hypocrisy and the lack of answers to the missing pieces. I struggled, but I did not abandon my commitment to know the truth. God is leading me to the simple understanding of his relevance and I am relearning what the church taught me as a youth… that he loves me, that he has led me to a knowledge of him such as I have never known. He is using Dr. Jennings to connect the dots that are now so apparent and hiding in plain sight!

Dean P., Arlington, TX, USA

 

Testimony 22

I have found your Bible study class lectures to be very inspiring and useful as I prepare to teach class every other week. I subscribe to the podcast and download your notes on the weeks I teach. The audio and notes are such a great help in preparing. My own understanding of God’s character has grown as I teach the class. Commendations on the thought-provoking and well-prepared material Come and Reason provides. Personally, I get excited by the tie you make between the spiritual and mental/physical domains.
