Another one of Our Beloved Sisters sent me this excerpt concerning the observation and understanding of how the heart communicates with the body and is more influential than the brain. As we plant The Seed of the Word in our hearts, It will impact the rest of the body as FATHER designed. Man is now able to observe physiologically at least to some degree how it works. We simply trusted FATHER to begin with! The spirit of man resides in the heart and then influences the mind and the body through “transformation” to renew our minds and instruct our bodies.
The following is an excerpt and a detailed explanation:

CHAPTER 5
Scientific Discovery and the Heart
…understand with their hearts and turn, and I would heal them. Matthew 13:15
Perhaps one of the world’s more bizarre murder convictions occurred following an eight-year-old girl receiving the heart of a murdered ten-year-old girl. According to prolific writer and best-selling author, Paul Pearsall, Ph.D., the young heart recipient began having detailed and vivid dreams of a little girl being killed. Disturbed and unsure how to help their eight-year-old daughter, the parents took her to a psychiatrist for help. After several sessions, the psychiatrist determined that the girl’s dreams were most likely memories of real events and recommended that the parents contact the police.
Because the typical protocol for a heart transplant includes the sharing of information on the donor’s gender, age, and cause of death, police suspected that the girl in the dreams was the heart donor. Once armed with the knowledge of specific details of the crime from the child’s dreams, (such as the weapon, time, place, clothes worn by the killer, and what was said), police found and convicted the ten-year-old girl’s killer.[7]
Although the protocol for heart recipients entails anonymity for the donor, in many cases, unexplainable changes in the recipient’s personality and behavior cause them to seek out information about their donors. Pearsall investigated seventy-three such cases and published his findings. Each story begged the question: If the heart merely functions as a pump for blood, how can the donor’s memories be transferred to the recipient through a transplant? Although various theories exist, perhaps recent research reveals the answer: The heart does have the capacity for memory. A research group called the HeartMath Institute has the following to say on the topic:
More recent research shows that the neural interactions between the heart and brain are more complex than previously thought. In addition, the intrinsic cardiac nervous system has both short-term and long-term memory functions and can operate independently of central neuronal command.[8]
The fact that the physical heart has a memory provides an interesting precursor to sharing with you the many details that have emerged in the last fifty years of scientific research on the heart. Those details confirm the biblical principle that out of the heart (spirit and soul) flows life! My desired approach in making a case for the foundational role of the heart in one’s health is to give it the old, one, two punch. So, in the last chapter, I looked at the crucial impact of the heart from a biblical perspective. After all, the Bible should be our starting place as Christians. With that as our foundation, I now I wish to delve into the fascinating world of recent, scientific research, which highlights the heart’s ability to either prevent illness in the first place or to cause it. The research also confirms that the emotional state of the heart facilitates recovery or healing once sick.
To prove such claims I must use medical jargon and quote from the experts. Please, do not let that deter you from the simple theme found at the center of it all–the emotional state of your heart impacts EVERY area of your health. That simple understanding provides a critical foundation or starting point on the path of life.
The Lacey’s Foundational Research
During the 60’s era of Vietnam and the Civil Rights movement, a new line of scientific research also emerged that considered the impact of psychology on parts of the body such as the heart and the brain. A unique and pioneering husband-and-wife team–the Laceys–led the way.[9] Born in 1915, John I. Lacey grew up in a century of discoveries. His original interest centered on engineering, but while still a student at Cornell University he sustained an injury on the fencing team, which left him laid up in bed. Not one to idly waste away time, John used the downtime for reading on new subjects. Branching out from his studies as an engineering student, he found fresh interests in books on psychology and biology. Mr. Lacey’s biographers indicate that a new passion resulted from those readings, which eventually led to a change in career direction.[10] After a time serving in the military during World War II, John and his wife, Beatrice (known as Bea), led the way for a new branch of science, known as psychophysiology.
At that time the Laceys asked novel questions that still interest us today and which guided their meticulous experiments and studies for thirty years.
Why do some individuals become ill while others do not when exposed to similar pathogens and situations?
Why are some individuals more or less resilient to the effects of psychological stress?[11]
Have you ever noticed how individuals often respond with great differences to the same exact surgery, procedure, diet, or drug? One person recovers from major surgery in a fraction of the time as another. One individual with stage four cancer somehow survives, while another dies quickly. Now, biological factors certainly play into this, but the Laceys suspected and proved that one’s emotional state has a tremendous impact on one’s physiological response.
To understand how the heart impacts the health of the whole body, let me define a crucial term–the autonomic nervous system (ANS). The ANS controls the subconscious or automatic processes of the body such as digestion, metabolism, heart rate, blood pressure, kidney function, sexual arousal, body temperature, and countless other bodily processes. Obviously then, the ANS is a critical force in the body. With that crucial nature in mind, consider this: If the autonomic nervous system controls so many vital aspects of the human body, anything that influences the ANS will have a power beyond description to impact the overall health of the body.
If you are like most people, you probably assume if something wields power over the autonomic nervous system, it must be the mighty brain. However, the Lacey’s clinical research revealed the brain takes a back seat to the heart. The authors of a book called Science of the Heart–Exploring the Role of the Heart in Human Performance summarize the Laceys’ surprising findings:
As their research evolved, they found that the heart, in particular, seemed to have its own logic that frequently diverged from the direction of autonomic nervous system activity. The heart was behaving as though it had a mind of its own. Furthermore, the heart appeared to be sending meaningful messages to the brain that the brain not only understood but also obeyed. Even more intriguing was that it looked as though these messages could affect a person’s perceptions, behavior, and performance.[12]
More specifically, they discovered a nerve pathway and means by which the heart could either hold back or aid the brain’s electrical activity. In other words, the heart influences and directs the brain, not the other way around! This evidence confirms the words of King Solomon about the heart– for from it flow the springs of life.[xxviii]
While the Lacey team continued their research, another related, scientific branch emerged called neurocardiology. This collaboration of scientists and cardiologists made a remarkable discovery of a little brain in the heart. This heart-brain, as Dr. J. Andrew Armour first called it,contains 40,000 neurons, as well as a network of the same components that make up the brain in the head.
In other words, the heart has its own, independent central nervous system, which is undeniably seen every time a surgeon performs a heart transplant. Professor Salem from Harvard explains this phenomenon:
Normally, the heart communicates with the brain via nerve fibres running through the vagus nerve and the spinal column. In a heart transplant, these nerve connections do not reconnect for an extended period of time; in the meantime, the transplanted heart is able to functionin its new host only through the capacity of its intact, intrinsic nervous system.[13]
The Heart Affects the Autonomic Nervous System
Medical science once assumed that the brain took care of all of the neural processing of information, but with the discovery of the heart-brain, a different picture of body function emerged. The heart-brain may be small, but it influences the autonomic nervous system!
Everyone constantly experiences the impact of the heart-brain on the ANS. Have you ever gone to the doctor’s office and had your blood pressure increase from the anxiety of being there? Or, perhaps you have experienced the common complaint of becoming constipated or having episodes of diarrhea during a time of stress? The examples are endless. The simple explanation for such occurrences is that the heart-brain sends messages about your fear, anxiety, etc. to the parts of the brain that, in turn, stimulate the ANS and, voila; the automatic functions like digestion or heart rate respond accordingly. Although the brain directly messages the ANS, the heart initially kicks the brain into gear.
You might wonder how the heart, as opposed to the brain, can have so much power over the autonomic nervous system. The answer lies in understanding a bit about the way in which the heart and brain communicate. Nerve pathways run up and down through the spinal column and vagus nerve between the heart and the brain. Think of the vagus nerve as major interstate that allows for nerve travel between the brain and the abdomen. Some lanes (fibers) go north and some go south. All along the way, the vagus nerve has exit ramps to other highways so that information can quickly travel from the brain to the other parts of the body.
How neural information travels from the brain to the heart has been known and accepted for some time, but the pioneering neurocardiologists observed something radical. More fibers (lanes) in the vagus nerve are related to the cardiovascular system than to any other organ, which means that the heart sends more information to the brain than the brain sends to the heart.[14] The information from the heart travels up the vagus nerve to several key parts of the brain.[15]
The HeartMath Institute extensively studied the effect of the heart on the autonomic nervous system by measuring the heart rhythms of countless individuals under a multitude of situations. They have focused many studies, specifically on heart-brain interactions, while their subjects experience emotional input. They state, It is well known that mental and emotional states directly affect activity in the ANS. Thoughts and even subtle emotions influence the activity in the autonomic nervous system.[16]
You might be surprised at the following list of conditions associated with the autonomic nervous system, which mere thoughts and subtle emotions can bring about. These include depression, hypoglycemia, panic disorder, sleep disorder, asthma, fatigue, dizziness, nausea, irritable bowel, fibromyalgia, hypertension, chemical sensitivity, premenstrual syndrome, anxiety, migraine, and arrhythmia.[17] To put it simply, those pesky thoughts and emotions that we feed and water constantly have been scientifically proven to cause the heart to send messages that directly impact EVERY area of health through the ANS. Wow! Perhaps that is why the Bible instructs us to take every thought captive to make it obedient to Christ.[xxix]
The Heart Affects Hormones
Without getting bogged down in the complexity of each part of the brain, let me just zero in on two of those parts (first the hypothalamus and then the amygdala) to highlight the crucial nature of the heart’s influence on the body. Since every woman knows the importance of balanced hormones and the suffering that comes when they get out of whack, I will start with the hypothalamus. This almond-shaped portion of the brain functions as the link between the endocrine system and the nervous system. As a result, it impacts a host of hormones in the body. According to Endocrine Web,
The hypothalamus is arguably the most essential of the endocrine system. By alerting the pituitary gland to release certain hormones to the rest of the endocrine system, the hypothalamus ensures that the internal processes of your body are balanced and working as they should.[18]
Obviously then, anything that stimulates or inhibits this part of the brain will have far-reaching health implications. Studies show unequivocally that our thoughts and emotions cause the heart to send out signals to the hypothalamus (either helpful or harmful), which regulate the hormonal system.
So, if your hormones, in particular, create misery for you, you have a very strong indicator that your heart needs attention. Please, do not dismiss this! Hormone supplementation is a band-aid approach to a heart issue. Now granted, changes in life such as pregnancy, menstruation, and menopause, as well as other conditions, will also cause changes in hormones. However, based on research showing the impact of the heart on hormones, the severity of symptoms of hormone imbalance, even at those times, may stem more from an individual’s heart than anything.
As I have previously shared, I know first-hand the phenomenal impact that thoughts and emotions have on the body, and the havoc they wreak on the hormonal system. After the doctor declared me the worst case he had ever seen for hormone imbalances, I began taking a large assortment of prescription and compounded hormones to cover all the bases. Taking those hormones helped me somewhat for a time, but the problems continued. I did not know for years that the root issue causing my severe hormone imbalance was my hurting heart. Oh, how it grieves me to learn of others suffering endlessly from hormonal issues. A better way–a path of life–does exist, and it begins with the heart.
In addition to the heart influencing the hypothalamus, did you know the heart itself produces a number of hormones? Not only do the heart and brain communicate neurologically, but we also now know they communicate biochemically through the hormones that the heart produces and secretes. Many people have a general understanding of the crucial role neurotransmitters (hormones such as norepinephrine, epinephrine, dopamine, and oxytocin) play in brain activity, but most assume that all of these important hormones come only from the brain itself. Such is not the case.[19]
In 1983, scientists discovered that, in addition to the heart’s production of neurotransmitters, it also produces a balancing hormone unique to itself. This critical hormone has some unwieldy names, of which I will use the simplest–atrial peptide (ATP). This amazing hormone affects numerous body functions such as balancing blood vessels, kidney function, the adrenal glands, as well as regulatory centers in the brain.[20] The fact that the ATP released by the heart increases the release of stress hormones demonstrates one simple tie between stress, the heart, and the body. Remarkably, ATP even appears to affect the immune system.[21] Once again we see proved true God’s insight as shared by King Solomon–Keep your heart with all vigilance, for from it flow the springs of life.
Emotions and the Heart
I have touched on how stress affects the heart, and thereby the rest of the body. However, when I say stress, I am talking about an emotional response to one’s circumstances. What makes a particular situation stressful? To me, riding a roller coaster is great fun, but to many people, even the thought of doing a high-speed drop or loop strikes tremendous fear into their hearts. The degree of stress experienced or lack thereof has much to do with our emotional response to a particular situation.
That emotional response comes from the heart, but a very small part of the brain called the amygdala processes those responses. When we encounter a stimulus from our environment, the heart stimulates the amygdala. Remarkably, the amygdala compares stored emotional memories with the incoming environmental information from the senses. It then instantaneously determines the perceived threat level and causes the body to respond accordingly.
For example, when an abused child instantly raises his arm to protect his face every time someone lifts a hand near him, the amygdala is at work. When you smell apple pie, and your whole body relaxes because of the stored memory of your loving grandmother’s apple pie, the amygdala also cued that physiological response. When I miss my turn while driving, my amygdala triggers my heart to race and general panic to ensue because it processes the emotional memory linked to when I missed my turn to Ashville, NC and almost ended up in Nashville, TN. (Or, it could be remembering the time I got lost for two hours at night while making a twenty minute trip home from the mall. Who knows? The memories to choose from are numerous!)
The point is that not only do our current emotions affect our health but so also do our emotional memories. Both the past and the present dictate our physical responses before we even have time to think about them. Doc Childre, the founder of the HeartMath Institute, describes it this way:
Since emotional processes can work faster than the mind, it takes a power stronger than the mind to bend perception, override emotional circuitry, and provide us with intuitive feeling instead. It takes the power of the heart.
The Heart’s Biomagnetic Field
Another aspect of the heart I cannot ignore in a discussion on the impact it has on health is its power to draw other organs into its rhythm. In 1863, Gerhard Baule and Richard McFee first discovered evidence of the heart’s magnetic field by using a magnetocardiogram (MCG). Then in the 1970s, a far superior machine called a superconducting quantum interference device (SQUID) revealed that the heart generates an electrical field one hundred times greater than that of the brain. In fact, the heart’s magnetic field can be detected anywhere on the surface of the body and up to three feet away.[22]
A study by the HeartMath Institute even showed that while sleeping next to each other, couples who have been together for years frequently end up with their heart rhythms in sync during the night. In multiple other studies, the Institute also demonstrated that when an animal is close by its master, the pet’s heart rhythm begins to match his master’s.[23] If the heart’s pull can draw others into its rhythm, imagine its pull on every part of the body, for good or for bad.
The HeartMath Institute also conducted some fascinating studies revealing a direct relationship between heart-rhythm patterns and the heart’s magnetic field. Their studies indicate that a person’s emotional state is encoded in the heart’s magnetic field and is communicated throughout the body and into the external environment.[24] Just consider some of their conclusions quoted below:[25]
wNegative emotions/feelings create disorder in the brain’s regulatory systems and ANS. www
wFeelings such as appreciation create increased order in the brain’s regulatory systems and ANS, resulting in improved hormonal- and immune-system function and enhanced cognitive function.
wPositive emotions are a reliable predictor of better health, even for those without food or shelter, while negative emotions are a reliable predictor of worse health even when basic needs like food, shelter, and safety are met.[26]
wThree 10-year studies concluded that emotional stress was more predictive of death from cancer and cardiovascular disease than from smoking; people who were unable to effectively manage their stress had a 40% higher death rate than nonstressed individuals.[27]
Best-selling author and practicing MD, Don Colbert, states the significance of the heart’s impact in Deadly Emotions:
The fact is, the strongest biological oscillator in the body is the heart. The heart has the ability to pull every other bodily system into its own rhythm, whatever that may be. When the heart is at peace or filled with love, it communicates harmony to the entire body. And conversely, when toxic emotions have triggered the heart to beat in an irregular way, to beat harder, or to beat faster, the heart communicates the very opposite of peace to the other organs of the body.[28]
Tying It All Together
All of this information about the heart clarifies the answers to the foundational questions the Laceys set out to explore. Some individuals become ill, and others do not when exposed to similar pathogens and situations because of the state of their hearts. Individuals are more or less resilient to the physical effects of psychological stress because of the state of their hearts.
Some of us know all too well the miserable state of our hearts, but just need the knowledge and understanding of how this impacts our health to be motivated to address the root issue. If this proves true of you, I urge you to shift your focus from your physical symptoms to your ongoing thoughts and emotions. Begin praying that God will heal your wounded heart. Choose thankfulness, joy, and singing instead of sadness and fear.
If, on the other hand, you have a chronic illness but are not aware of any need in your heart, I encourage you to consider what comes out of your mouth as a mirror of your heart’s true condition. Matthew 12:34 says,For out of the abundance of the heart the mouth speaks. Consider if any of the following scenarios apply to you:
Do you find yourself quick to offer a critical remark or to complain?
Do you find yourself verbally lashing out at others at the slightest provocation?
Do you find yourself frequently talking about the wrongs others have done to you or perhaps verbally expressing your anticipation of worst-case scenarios?
Do you tend to be like Eeyore from Winnie the Pooh and say things negatively or sadly?
These kinds of outward speech reflect the state of one’s heart. Whether or not you have good reason to fit into any of the above-bulleted scenarios matters little. The devastating impact on your health will continue until the heart issue changes. Chapter seven will lay out a biblical and practical way to achieve transformation, but a Christian counselor can also be a tremendous asset.
When my son Caleb was little, sugar and caffeine affected him greatly, and so I monitored his intake closely. One night we hosted a party of some sort and goodies of all kinds lined the bar of our kitchen throughout the evening. While I busily played hostess, Caleb had little supervision under extremely tempting circumstances. When bedtime arrived, I found him groaning in bed and holding his stomach. He readily confessed that my warnings on too much sugar causing tummy-aches now proved true in his experience.
Any time we experience symptoms, whether it is a tummy-ache or a chronic illness, the body attempts to alert us to an imbalance. In Caleb’s case, sugar caused the problem. Unfortunately, too often we attribute all physical imbalances to purely physical causes. However, as we have seen through both Scripture and science, the problem frequently begins with the heart. Perhaps it is time to assess your physical condition with a fresh perspective. Continue the journey with me on the path of life as we discover in the next chapter the key sign-post pointing the way for the heart.
