10 Simple Steps to a Healthy Brain

10 Simple Steps to a Healthy Brain

1. Regular Sleep

Approximately one in three Americans is chronically sleep deprived, sleeping less than seven hours per night. Sleep is one of four physical requirements for life, along with air, water, and food. Yet far too many people fail to provide their brain and body with adequate sleep.

Chronic sleep deprivation is devastating to brain health. Without regular adequate sleep brain function is impaired, particularly the part of the brain in which we attend, focus, organize, plan, self-restrain, calm self and modulate mood.

Chronic sleep deprivation results in higher activation of the brain stress circuits, with subsequent increase in inflammation and oxidative stress – cellular damage to body and brain. This increases the risk for illness of brain and body such as, diabetes, obesity, depression and dementia.

A healthy brain requires regular sleep.

2. Regular Exercise (Both Physical & Mental)

According to the Centers for Disease Control, more than one third of US adults (35.7%) are obese.

Obesity is a high inflammatory state that reduces quality and length of life and results in accelerated aging and loss of brain tissue. A combination of a high sugar, high saturated fat diet and lack of regular exercise are primary contributing factors to obesity.

Regular exercise not only results in better physical health, and generally better weight profile, but also causes a cascade of beneficial events for the brain. Regular exercise causes the muscles to produce powerful anti-inflammatory cytokines that reduce inflammation. Exercise increases blood vessel growth in the brain improving oxygenation. Additionally, regular exercise causes the brain to produce proteins that stimulate the brain to make new neurons and increase the growth neuron-to-neuron connections. People who exercise regularly are at lower risk for dementia. Finally, exercising the brain itself by engaging in mentally stimulating activities, puzzles, Bible study, learning a new language etc. activates growth factors that promote brain health. If you don’t use it, you will lose it – so exercise regularly!

3. Hydration

Water is the single largest component of your body comprising well more than half of your body weight. Every cell of the body requires water. Water is essential for the functioning of our cells and the removal of waste products of metabolism.

Dehydration shrinks the cells of the body and their function becomes impaired. This results in increased oxidative stress and inability to clear toxins, which results in greater damage to our cells, including our brain. Concentration, memory and general alertness can be negatively affected by dehydration.

An average adult should drink eight 8-ounce glasses of water each day, and more if exercising vigorously, or working in hot humid environments in which sweating profusely.

4. Healthy Diet

You have probably heard the old adage we are what we eat. Well there is much truth in this saying. What we eat provides the nutrients and building blocks from which the tissues of our bodies are made.

Diets high in sugar and saturated fats increase inflammation and oxidative stress accelerating the aging process and decline in brain function. Conversely, diets high in fruits, nuts, grains, vegetables, cold-water fish, olive oil, provide antioxidants, which reduce inflammation and slow the aging process.

In general, the more highly processed the food the less healthy and more damaging to body and brain. The less processed the food the healthier for body and brain.

5. Avoid Toxins

It doesn’t take much brain power to figure out that tobacco, heavy alcohol use, and illegal drugs are damaging to body and brain and accelerate the aging process. But one toxin often missed is high caffeine use. While one or two caffeinated beverages may not confer great risk, higher amounts do increase inflammation, interfere with sleep, reduce blood flow to the brain and increase oxidative stress on the brain.

Other potential toxins, for which we have concern, but not solid evidence, include the myriad of man-made chemicals infused into our society. Read the labels on many household items and you will discover a long list of man-made chemicals, to which we are daily exposed. Only time and research will tell the full impact on physical and mental health these substances are having.

6. Forgive

Grudge holding, bitterness, resentment are toxic emotions that activate the brain’s stress pathways causing activation of inflammatory factors. Failure to resolve such feelings results in increased oxidative stress and damage to physical, mental and relational health. Forgiving those who have offended us does not mean what they did was okay, but relieves us of carrying the toxic emotions of anger and resentment everywhere we go and over time ruining our own health.

7. Develop Healthy Relationships

Relationship conflict activates the brain’s stress circuits, which turns on the immune system causing increase levels of inflammatory factors. Chronic relationship conflict also interferes with regular sleep. The combined effect of increased inflammation and sleep deprivation accelerate aging and undermine brain health. People with chronic relationship problems have higher rates of mental and physical health problems.

Conversely, healthy relationships are protective and reduce the incidence of both physical and mental health problems. Adolescents who grow up in homes in which they have one adult who is a close confidant perform better in school, get more awards, have less depression and lower rates of drug problems.

8. Be a Giver

Multiple studies have demonstrated that persons who are involved in any form of regular volunteerism have better physical health, lower blood pressure, are on less medicines, maintain independence longer in life and have lower rates of dementia.

Loving other people is healthy for the brain.

9. Minimize Theatrical Entertainment

Brain research has demonstrated that theatrical entertainment (but not education programming) alters the brain structure, resulting in decreased development of the prefrontal cortex (higher brain where we plan, organize, self-restrain, attend, have good judgment), and over development of the limbic system (lower brain where we experience fear and irritability). This occurs in a dose dependent fashion, meaning the more TV watched the more damaged done. This imbalance increases the risk for attention problems as well as anxiety and mood problems.

Minimizing theatrical entertainment is protective for the brain.

10. Build relationship with God of Love

Individuals with a healthy spirituality, focusing on a God of love, have reduced anxiety, stress and overall more meaningful and satisfied life. Research shows healthy spirituality reduces rates of suicide, increases life satisfaction scores, and general results in healthier relationships and lifestyle.

Conversely, God constructs that incite fear are associated with increased anxiety, dread, worry, relationship conflict and a general sense of life dissatisfaction, all of which increase inflammation and are unhealthy for the brain.

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!

My husband is a pastor and I listen to your lesson almost every week. Thank you for helping me in my study life and to help me love the “real” God more.

Testimony 18

The Healing the Mind DVD set tarted me on a journey that has changed my relationship with our loving God more significantly than any other study, and brought me to your book and Bible study podcasts, which I now listen to daily, thanks to the availability of archived content on your site and on iTunes.

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!

Testimony 21

I am absolutly on fire with the message at Come and Reason! I can’t get enough! I’ve read your book, blog, and articles. I’ve listened to your Bible study podcasts, your radio show, and your series – all excellent! It wasn’t until the past couple of years that I have I like I’m becoming “healthy,” with more to share with others than just beasts and commandments! I used to be a Bible worker and preached when the pastors were gone until I had had enough. I didnt realize at the time what the problem was, but i know now… the message wasn’t properly focused. Now my flame is rekindled. All of your little examples are so perfect in explaining something “complicated” and making it easily understood! Now I’m trying to shape it into a life changing evangelistic series! Thank you!

Testimony 20

I just wanted to personally thank you for your teachings and insight into scripture. I came across your website via my cousin who suggested I look into “Healing the Mind” information. My youngest daughter has been struggling over the last couple of years and it all came to a head this spring. When I started listening to the “Healing the Mind” lectures my own life began to be transformed. I began sharing with all my daughters the concepts you laid out so clearly. I ordered your book and soaked it up. I just want to say “Thank You!” My walk with the Lord has been refreshed and renewed. Your obedience to the Lord is a blessing to so many.

Testimony 75

Thank you so much for everything you do! Because of all these truths, I’m excited to be with Jesus! I always pray everyday, “COME TODAY, JESUS.” Before finding C&R, I was always praying for delays, “NOT TODAY OH GOD. I AM NOT READY.” I just need to share more, talk more bout this truth, so everybody will be excited for Jesus.

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)

Testimony 58

I have been watching your videos in The Power of Love seminar and I must say these have liberated me and have improved my relationship with the Lord. I am no longer terrified of him as I was before following your teachings.

Testimony 54

I had a lot of pressure, as a pastor’s kid, to conform and be “good.” I was good at being “good.” I thought my life was going along well until it all started falling apart and I could not figure out why! In my search for “why is this happening to me, God?” I came across your book, “Could it be this Simple,” and God started revealing to me the many distortions I held about His character, His principles, and how He has designed His universe to operate. I remember thinking, “Wow, I have had this all backwards.” I was happy and angry all at the same time. Happy to have the light of truth break through the darkness, revealing a wonderful, beautiful way of understanding God and His plan for His children, and angry, because I felt deceived and cheated by the church, my family, and myself!

My heart thrills when I listen to your bible study lessons. Literally I have gone from death to life. It is a journey I look forward to every day, as God reveals areas this distortion affects. Praise GOD! I will ever be grateful to God for this ministry and your cooperation with the Spirit!

I have been really blessed reading your response to the various questions on your site.

Testimony 34

I was introduced to Come and Reason Ministries by accident, via a passing comment made in a bible study class we were visiting. I checked this website out and my life was changed. The understanding of the truth of God’s character, and how we apply it, is so right. The tricky part is consistently applying which “lens” to look through. As I began to understand, I started sharing the basics of this understanding with a discussion group I was leading and, suddenly, a lot of things started to make sense that never used to. At the same time, I enjoyed an amazing opportunity. I was able to conduct a full bible study at WORK! What an amazing experience! It is such a joy to share the truth about God and to share how it all fits in the war between God and Satan. So many people benefit when we have a correct understanding about how God works and who He really is! Thank you for this transformational understanding. Keep up the good work! God Bless you!

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.

Testimony 35

I am so pleased with the response your message is receiving at my church from the middle-aged to the young adults. I have given out 100 copies of the first two seminars and there are more request every week. One of my [class members] came to me after viewing the series, grateful and impressed with how easy the message was retained. He had been a Seventh-day Adventist in fear all his life, and felt like the scales were removed from his eyes after viewing the seminars. I am so impressed by the change I see in members who have received this message, we are in one accord. However, I am sadden by the negative response of the older people. I am verbally attacked anytime I talk about imposed laws, but I believe my mission is to enlightened everyone I can. I watch your Bible Study Class on YouTube every Friday night and I feel like I am apart of the class. All of you are in one accord and I am so blessed to have found you. I pray that all of you continue to spread this message and I am committed to doing my part.

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.
