Winston Churchill said, “There is nothing to fear except fear itself.” Have you ever wondered about that famous statement? Imagine walking a four-inch wide balance beam placed securely on the ground, your feet only a few inches from the dirt. Now imagine walking that same beam raised 100 feet in the air. Would your ability to successfully traverse the beam be negatively affected as you look down from such a height? What changed? Fear!

When we are afraid, the brain’s fear circuit (amygdala) activates, which floods the body with surges of stress chemicals (adrenalin and glucocorticoids). We experience the classic “fight or flight” response in which blood is shunted from our internal organs to our muscles and glucose is dumped into the blood stream. This is to bring us to quick attention in the face of an external threat, like the house being on fire. However, chronic fear, fear of failure, fear of rejection, fear of what others think, fear of financial ruin, and chronic worry of any kind keeps the fear circuits firing, which activates the body’s immune system, increasing inflammatory factors that injure our bodies. Under chronic fear, worry, and stress these inflammatory factors damage insulin receptors, increasing the risk of diabetes mellitus, obesity, high cholesterol, heart attacks, and strokes.

Chronic fear also impairs growth of all types. A recent study documented that Iraqi children growing up in war zones were measurably shorter than Iraqi children growing up in rural safe zones. Fear impairs physical growth![i]

Maybe you have known someone with test anxiety or someone who froze when getting up in front of an audience. What happened? Their fear circuits fired, paralyzing their prefrontal cortex (thinking circuits). Intellectual and cognitive growth is impaired when we are afraid.

When something really frightens you, like smelling smoke as someone yells fire in a theater, where does your focus turn? Do you become more concerned with the strangers in the room or more concerned with saving self? The more fearful we become, the more self-focused we become.  Fear impairs relational growth!

When we believe God concepts that incite fear, the ability to grow spiritually is impaired. It is in the prefrontal cortex (located right behind the forehead) where we reason, plan, organize, focus, concentrate, and self-restrain. It is also in the prefrontal cortex where we have our conscience, redirect inappropriate behavior, and worship. A special part of the frontal cortex, called the anterior cingulate cortex (ACC) is our neurological “heart.” It is here where we experience altruistic love and empathy.  The ACC is also the seat of the will, the place we choose right from wrong. The proverb, “As a man thinks in his heart so is he” (Proverbs 23:7) is referring to the ACC.

Amazingly, brain research has demonstrated that people 60-65 years of age who meditated on a God of love, just 12 minutes a day for 30 days, experienced measurable growth in the ACC of their brains. This was directly correlated with reductions in heart rate, blood pressure and a 30% improvement in memory testing  [ii]. Meditating on a God of love reduces fear and is healing to our being. Science confirms what the Bible tells us, “perfect love casts out all fear” (1John 4:18).

But, just as strikingly, brain research confirmed that meditating on angry, wrathful and punishing god concepts did not result in positive growth in the ACC, nor provide the beneficial reductions in blood pressure, heart rate, and improvement in memory. In other words, angry or wrathful god concepts do not heal the brain, improve love, or enhance prefrontal cortex function. Instead, believing such concepts activates the fear circuits of the brain and contributes to impairments in healthy growth, thinking, reasoning, and relationships.

Love acted out is also healing. Research documents that youth who volunteered (love others with acts of altruism) experienced greater academic achievement, civic responsibility, and life skills that include leadership and interpersonal self-confidence than those who didn’t [iii]. And adults who volunteered (after accounting for variables such as education, baseline health, smoking, etc.) lived longer, had less illness, less disability, less depression, less dementia, and lived independently longer than those who did not [iv].

Fear is our enemy, it infects us, drives us toward destructive thinking, living and reacting. Whereas, love is the only power capable of freeing our hearts from fear and bringing genuine healing to our minds, bodies and relationships. So love well. Love always.

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.
