The brain is the grand conductor of the symphony of our selves. The brain leads mind and body, and the brain heeds mind and body. The brain plays a role in every thought, feeling, and body sensation we experience. That includes every twitch, every blink, every strum of a guitar, and even every orgasm. That also includes every dream, passion, fear, joy, and deepest desire.
Every memory you consolidated last night while you slept, each micro-movement used to brush your teeth this morning, every smoothie you tasted, step you took, daydream you pondered, daydream you snapped out of, work you intently focused upon, yawn you took, anxiety you felt, drop in blood sugar you experienced, was a manifestation of lots of talking. A plethora of dialogue went on inside of you today, and you need to know it.
Quick Brain Basics:
The brain and the spinal cord make up the nervous system, composed of billions of nerve cells (i.e. neurons) that speak back and forth between the brain and body. What’s the conversation like? Well, the nervous system is at least bilingual, and speaks both electrically and chemically. When neurons (the brain’s cells) are stimulated, an electrical impulse, called an action potential, is created. This eventually leads to the transmission of chemical substances called neurotransmitters, like norepinephrine, dopamine and serotonin, which we know play a huge role in our mood functioning, among a lot of other things.
Why is it so important to know how much chatter the brain is doing? Because to be mindful of the orchestration of our internal states (some in reaction to the external) is to be mindful of the essentiality of nourishing our brains.
The latest scientific research shows that neuroplasticity, the idea that new neurons can be created, makes it very possible for lifestyle to play a big role in maintaining and improving brain function. Of course, as always, nature and nurture dance an exquisite but complex dance, and so there is never one solution or one cause and effect paradigm when it comes to your wellness. Yet, there is something each of us can do to help our brains stay vital:
1. Reduce your stress levels by practicing mindfulness meditation.
Although stress is a temporarily adaptive response to a threat, when it is chronic it becomes maladaptive and can wreak havoc on the central nervous system (CNS). Stress-reduction and relaxation techniques are important for a healthy brain. A widely used relaxation-inducing technique is meditation. Mindfulness meditation has been shown to be particularly effective. Studies have indicated that the amygdala, known as our brain’s “fight or flight” center and the seat of our fearful and anxious emotions, decreases in brain cell volume after mindfulness practice. Mindfulness meditation has been shown to help ease psychological stresses like anxiety, depression, and pain. Research is still parsing out the exact mechanisms, but many agree that on a cognitive level, mindfulness’s ability to cultivate attention on purpose, in the present moment, and non-judgmentally, helps reduce the stress elicited by past and/or future oriented thinking.
2. Get your blood pumping through exercise.
Exercise is a life force, and there are many reasons why it is a crucial part of basic brain hygiene. One reason is that exercise actually raises serotonin levels (most antidepressants focus on the production of serotonin). That’s just the tip of the iceberg though with regards to exercise’s benefits, which is why it is always in my top three recommendations to clients who want to thrive cognitively as they age.
3. Use it, so you don’t lose it, by engaging in mental stimulation.
Lifelong students have the right idea when it comes to staving off age-related brain decline. Continued learning actually promotes brain health, and might actually create new neural connections. This kind of neuroplasticity is a handy defense against future cell loss. So in essence, taking a stab at a crossword puzzle, or enrolling in a continuing education course can help build cognitive reserves. The biggest bang for the brain are tasks that are challenging, varied, and novel.
4. Nourish your body and brain with balanced nutrition.
Our brain’s health is dependent on our many lifestyle choices that mediate gut health, including most notably diet i.e., reduction of excess sugar and refined carbohydrates, and increased pre and probiotic intake. Poor gut health, elicited by dysbiosis (a shift away from “normal” gut microbiota diversity), may contribute to disease, and has been implicated in neurological and neuropsychiatric disorders like multiple sclerosis, autistic spectrum disorders, Parkinson’s disease, and even Alzheimer’s disease. Further, there is now research that suggests that depression and anxiety are mediated by poor gut health as well.
5. Stay positively connected to yourself and others by socializing.
Joining a community center, or even a meet-up group adventure is actually an investment in your future. Research continues to support the positive impact of social interaction on the brain. So much so, that studies even go so far as indicating that social interaction is a key to warding off dementia, including the Alzheimer’s. Even basic exchanges with people keep our brains stimulated as it searches for thoughts and a way to organize them into appropriate communication bytes. Also, let’s not forget that being part of a social network often elicits healthy behaviors, most notably joining a walking group, or engaging in other group exercise. So, keep your friends and family close to help maintain cognitive processes.

Running half-marathons barefoot in the snow. Climbing mountains while wearing only shorts. Standing in a cylinder filled with 700 kilograms of ice cubes.
Self-proclaimed “Iceman” Wim Hof, claims that he can do all of these things by influencing his autonomic nervous system (ANS) through concentration and meditation. The “Wim Hof Method,” is an intensive meditative practice that includes focused concentration, cold water therapy, and breathing techniques. Until recently, the idea that anyone could influence their autonomic nervous system was thought impossible given its assumed “involuntary” nature. The ANS is the system that controls all of our internal organs and regulates body functions like digestion, blood flow, and pupil dilation.
Our brains also use the ANS to communicate to our immune system, which might explain another of the Iceman’s recent feats: suppressing his immune response after being dosed with an endotoxin (a bacteria), which in most people leads to flu-like symptoms and high levels of inflammation in the body. When researchers looked at the Iceman’s inflammatory markers after being exposed, they discovered the markers were low, and his immune response was 50% lower than other healthy volunteers. Basically, he showed very few signs of infection.
Hof is definitely a statistical outlier, though one recent study followed students trained in his method. Apparently, they replicated Hof’s results and experienced no symptoms after being injected with Escherichia coli, a bacteria that normally induces violent sickness.
So, outlier though he may be, researchers are intrigued by the mounting evidence showing that mindfulness has a positive impact on our immune system.
The Floating Brain: Our Best Defense
The immune system is one of the most critical purveyors of our physical wellness. It’s our defense system, our armed forces that work to protect us from foreign invaders like viruses or bacteria. It is so precisely designed that it can distinguish between harmful unwanted pathogens and our own healthy cells and tissue.
It is so wise that the immune system has even been referred to as our “floating brain,” aptly named for its ability to communicate with the brain through chemical messages that float around inside our body. This means that if our immune system is weakened, perhaps as a result of chronic stress or invading pathogens, our whole body system won’t operate as usual. When our immune system struggles, it’s like a welcome sign for infection and disease.
Mindfulness and the Immune System
Beyond the Iceman’s superhuman experiences, there is increasing evidence that mindfulness meditation does impact our immune system.
A recent and groundbreaking review looked at 20 randomized control trials examining the effects of mindfulness meditation on the immune system. In reviewing the research, the authors found that mindfulness meditation:
- Reduced markers of inflammation, high levels of which are often correlated with decreased immune functioning and disease.
- Increased number of CD-4 cells, which are the immune system’s helper cells that are involved in sending signals to other cells telling them to destroy infections.
- Increased telomerase cell activity, the cells that help promote the stability of chromosomes and prevent their deterioration (telomerase deterioration leads to cancer and premature aging).
These results need to be replicated with more rigorous methodology, but they are promising, and potentially pave the way for using mindfulness-based techniques to boost the immune system, enhancing our defense against infection and disease.
And this isn’t the only study showing positive results. In another eight-week study, researchers at UCLA had 50 HIV-positive men meditate daily for 30-45 minutes. Doctors found that, compared with a control group, the more training sessions the men attended the higher their CD-4 cell count at the conclusion of the study (remember, CD-4 cells are the immune system’s helper cells). This study links mindfulness with a slowing down in CD-4 cell count drop, which is associated with healthier immune system functioning.
Richard Davidson, esteemed professor at the University of Wisconsin-Madison, also conducted a study investigating whether mindfulness meditation could alter brain and immune function.
In his study, people were injected with the flu vaccine and were either part of a group receiving mindfulness training or a control group. After eight weeks, the mindfulness group showed greater levels of antibodies available to respond to, and prevent, potential illness.
Mindfulness Meditation and Possible Mechanisms of Increased Immunity
It’s tempting to get carried away by the implications of the research suggesting that mindfulness can help improve immune functioning. However, the question still remains as to the exact mechanisms involved in the mindfulness-immune system connection. Ask any researcher and they’ll tell you they don’t know yet. Some possibilities have been suggested, and it is likely that a convergence of all of these play a role. Here I present three possible ideas:
- Decreased Stress, Increased Emotional Regulation: It has been confirmed through research that what we think and feel impacts our immune system via chemical messages from the brain. Therefore, stress, negative thinking styles, and certain emotional states can have a negative impact upon our immune system, creating an environment increasingly susceptible to disease. Mindfulness’s mechanisms toward greater well-being are complex and multifold, but practice is implicated in decreased stress, decreased rumination, and increased ability to deal with difficult emotions. In this way, practicing mindfulness might stave off impaired immunity.
- Targeted Brain/Immune System Communication: Another link between mindfulness and the immune system is mindfulness’s direct impact upon brain structures responsible for talking to the immune system. More specifically, research indicates that mindfulness meditation increases activity in the prefrontal cortex, right anterior insula, and right hippocampus, the areas of the brain acting as our immune system’s command center. When these parts are stimulated through mindfulness, the immune system functions more effectively.
- Activation of the Second Brain (the Gut): Mindfulness can boost immunity via the gut microbiota. As per a previous article I wrote here on Mindful, the human body is comprised of trillions of micro-organisms, most of which reside in the gut, which are called the gut microbiota. It turns out that the gut microbiota are key players in the development and maintenance of the immune system; the bacteria in the body that helps distinguish between intruder/foreign microbes vs. those that are endogenous. Studies have shown that stress tips our microbial balance, putting us at risk for dysbiosis, (a shift away from “normal” gut microbiota diversity), stripping us of one of our prime defenses against infectious disease, not to mention the cascade of reactions that ensue, which potentially wreak havoc on the central nervous system (CNS). Mindfulness-based stress reduction impacts our immune system by helping to maintain healthy gut microbiota diversity that is often upset by stress.
No matter the exact mechanisms, there is viable evidence that practicing mindfulness meditation helps boost our defense against disease, and fosters wellness. And while we are a long way from this becoming a mainstream treatment practice—given possible egregious side effects if not done properly and the fact that very few of us can be an Iceman—this research paves the way for the addition of a new wellness adage: “Meditation each day keeps the doctor away.”

I am so grateful that my review regarding the mechanisms behind mindfulness’s positive impact upon psychological well-being was recently published by Dove Medical Press (with a video included!)

There is a lot of research conveying mindfulness meditation’s positive impact upon psychological well-being. In fact, a vast literature of controlled studies has found that mindfulness meditation is related to improved mental health across a variety of disorders, including different anxiety disorders, depression, eating disorders, substance abuse, and chronic pain symptom reduction.
Yet, the idea of mindfulness has become a buzzword of sorts, and despite research regarding positive outcomes, specific mechanisms associated with mindfulness and psychological well-being are unclear. (Additionally, the ambiguity in the term mindfulness, and how it’s approached in research, makes it difficult to parse out particular mechanisms responsible for clinical outcomes.)
Mindfulness and Attention Mechanisms
Despite these limitations, many research studies seem to indicate that cultivating different aspects of attention is a feasible and consistent starting point to bridging mindfulness practice and psychological well-being.
The question remains: How can cultivating multiple aspects of attention through mindfulness meditation account for psychological well-being?
This blog post is based on a review that supports a previously suggested idea that cultivating all aspects of attention through mindfulness leads to greater well-being by decreasing rumination.
Attention Networks
Like mindfulness meditation itself, attention is not easily defined. Over two decades ago, researchers conveyed a conceptualization of attention as a multifaceted construct made up of the three unique and differentiated, yet overlapping networks called Alerting, Orienting, and Executive Attention—the latter includes regulatory processes like conflict-monitoring and metacognition.
Attention Regulation
Attention is also described in terms of the way it is regulated. In fact, meditation practices are usually described by the degree to which they entail “Focused Attention (FA)” and “Receptive Attention (RA).” Although sometimes likened specifically to RA, mindfulness practice is distinguishable by its utilization of both FA and RA.
Focused Attention: When our attention is focused, it is restricted to a specific object, which is commonly the neutral sensory experience of the breath going in and out.
Ideally, attention is sustained, but as thoughts, and/or feelings and/or physical sensations arise, a conflict is presented; different stimuli are pulling for attention.
Receptive Attention: After consistent practice, there is often less need for a specific object of focus (the breath), and we broaden the focus of our attention so that it is receptive to our entire field of awareness, including whatever thoughts, feelings and sensations arise in the moment.
Rumination: Rumination has been defined as a passive dwelling upon negative thoughts and/or emotion and is negatively correlated with aspects of psychological well-being.
As mentioned, this review supports mindfulness meditation’s role in improved psychological well-being, through the mechanism of reducing rumination via attentional processes.
The question remains as to how this actually plays out.
Distraction and Decentering
Rumination is decreased through a two-step process including distraction and decentering. These steps correspond to the attention regulation styles inherent to mindfulness meditation.
Early on in one’s mindfulness meditation practice, when it entails focused attention, attention is sustained on the neutral sensation of the breath. While this skill is being cultivated, ruminative thought processes likely interrupt the effort to sustain this attention.
The ability to monitor conflicts of attention, however, ensures that one is constantly distracting oneself from ruminative thoughts through the redirection of attention from rumination back to the breath.
According to the research, distraction is a healthier response to stress than rumination and entails a deliberate direction of attention away from ruminative thoughts onto a pleasant or neutral stimulus. Yet, research also indicated that although distraction is important, it only serves as temporary relief, because with distraction, avoidance is taking place.
In the long term, avoiding and pushing away thoughts through distraction is as inefficient as clinging to them through rumination. So, there is a process beyond distraction. Mindfulness meditation utilizes the benefits of distraction, but then goes beyond it in cultivating a more adaptive response to distress.
This is enabled through receptive attention, during which attentional focus is broadened and one is encouraged to be aware of all experiences. One now has the space to actually notice patterns of over-engagement in negative thoughts as opposed to suppressing them through distraction.
The ability to cultivate a broader range of awareness also cultivates the ability to decenter, which is enabled through enhanced metacognition, and allows for a stepping back from any possible secondary elaboration of ruminative thoughts.
This means that thoughts are nonjudgmentally accepted as just thoughts that come and go. When thoughts are seen as transient, one is more likely to feel disconnected to them.
How Mindfulness Meditation Creates a Shift
The idea inherent in both distraction and decentering is that a shift is taking place. During the former, one’s ability to distract and redirect attention away from rumination and to sustain attention on the neutral breath is a literal shift in attention that cultivates regulatory processes intrinsic to psychological well-being. During the latter, one has the opportunity to figuratively shift attention from the content of a thought toward the process of having one. That vantage point allows for a more objective and less judgmental perspective. This perspective is more adaptive and reflected in greater psychological well-being. Ultimately, engaging in mindfulness meditation cultivates our ability to both focus and broaden our attention, which is a practical way to elicit psychological well-being.

Not too long ago, most of us thought that the brain we’re born with is static—that after a certain age, the neural circuitry cards we’re dealt are the only ones we can play long-term.
Fast-forward a decade or two, and we’re beginning to see the opposite: the brain is designed to adapt constantly. World-renowned neuroscientist Richie Davidson at the Center for Investigating Healthy Minds at the University of Wisconsin-Madison, along with this colleagues, want us to know three things: 1) you can train your brain to change, 2) that the change is measurable, and 3) new ways of thinking can change it for the better.
It’s hard to comprehend how this is possible. Practicing mindfulness is nothing like taking a pill, or another fix that acts quickly, entering our blood stream, crossing the Blood Brain Barrier if needed in order to produce an immediate sensation, or to dull one.
But just as we learn to play the piano through practice, the same goes for cultivating well-being and happiness. Davidson told Mindful last August that the brain keeps changing over its entire lifespan. And he thinks that’s very good news:
We can intentionally shape the direction of plasticity changes in our brain. By focusing on wholesome thoughts, for example, and directing our intentions in those ways, we can potentially influence the plasticity of our brains and shape them in ways that can be beneficial. That leads us to the inevitable conclusion that qualities like warm-heartedness and well-being should best be regarded as skills.
Davidson adds that research on neuroplasticity gives neuroscientists a framework for tracking meditation research. And CIHM is beginning to see that “even short amounts of practice,” like 30 minutes of meditation per day, “can induce measurable changes in the brain” that can be tracked on a brain scanner.
Based on recent research, I’ve chosen to share four ways your brain may change when you practice mindfulness:
• Anterior Cingulate Cortex: Increased grey matter changes were noted in the anterior cingulate cortex (ACC), which is a structure located behind the brain’s frontal lobe. It has been associated with such functions as self-regulatory processes, including the ability to monitor attention conflicts, and allow for more cognitive flexibility.
• Prefrontal Cortex: Increased grey matter density was also found in areas of the prefrontal lobe, which are primarily responsible for executive functioning such as planning, problem solving, and emotion regulation.
• Hippocampus: Increased cortical thickness in the hippocampus has also been noted. The hippocampus is the part of the limbic system that governs learning and memory, and is extraordinarily susceptible to stress and stress-related disorders like depression or PTSD.
Decreased Amygdala Size:
Studies have shown that the amygdala, known as our brain’s “fight or flight” center and the seat of our fearful and anxious emotions, decreases in brain cell volume after mindfulness practice.
Diminished or enhanced functionality in certain networks/connections:
Not only does the amygdala shrink post mindfulness practice, but the functional connections between the amygdala and the pre-frontal cortex are weakened. This allows for less reactivity, and also paves the way for connections between areas associated with higher order brain functions to be strengthened (i.e. attention, concentration, etc.).
Reduced activity in the Brain’s “Me” Center:
Mindfulness practice has been implicated in the decreased activation and the stilling of our Default Mode Network (DMN), which is also sometimes referred to as our wandering “Monkey Minds.” The DMN is active when our minds are directionless as it goes from thought to thought, a response that is sometimes likened to rumination and not always adaptive with regards to overall happiness.
The impact that mindfulness exerts on our brain is borne from routine: a slow, steady, and consistent reckoning of our realities, and the ability to take a step back, become more aware, more accepting, less judgmental, and less reactive. Just as playing the piano over and over again over time strengthens and supports brain networks involved with playing music, mindfulness over time can make the brain, and thus, us, more efficient regulators, with a penchant for pausing to respond to our worlds instead of mindlessly reacting.

Celebrated March 16-22.
Why is the Brain important?
The Brain is the grand conductor of the Symphony of Our Selves! That’s right. The Brain leads mind and body, and the Brain heeds mind and body. The Brain plays a role in every thought, feeling, and body sensation we experience. That includes every twitch, every blink, every strum of a guitar, every orgasm. That also includes every dream, passion, fear, joy, and deepest desire.
The Brain is the big boss and on top of that, it has a lot of nerve too!
Seriously speaking, the brain and the spinal cord make up the Nervous System, composed of billions of nerve cells (i.e. neurons) that speak back and forth between the brain and body. What’s the convo like? Well, the Nervous System is at least bilingual, and speaks both electrically and chemically. The latter refers to neurotransmission of substances like norepinephrine, dopamine and serotonin, which we know play a huge role in our mood functioning, among a lot of other things.
The neuro-nutshell is really just THIS: Miraculous.
Every memory you consolidated last night while you slept, each micro-movement used to brush your teeth this morning, every smoothie you tasted, step you took, daydream you pondered, daydream you snapped out of, work you intently focused upon, yawn you took, anxiety you felt, drop in blood sugar you experienced was a manifestation of lots of talking. A plethora of dialogue went on inside of you today, and you need to know it!
Why is it so important to know how much chatter the brain is doing?
To be mindful of the orchestration of our internal states (some in reaction to the external, some not) is to be mindful of the essentiality of nourishing our brains.
How do we nourish the Brain?
The latest scientific research shows: Neuroplasticity, the idea that new neurons can be created, makes it very possible for lifestyle to play a big role, no matter your age, in maintaining and improving brain function. Of course, as always, nature and nurture dance an exquisite but complex dance, and so there is never one solution or one cause and effect paradigm when it comes to your wellness.
Yet, there is something each of us can do to help our Brains stay vital:
- Reduce your stress levels (and SO much else) by practicing Mindful Meditation
- Get the blood a pumpin’ around up there via Exercise
- Use it, so you don’t Lose it, by engaging in Mental Stimulation
- Literally nourish your brain with Balanced Nutrition
- Stay positively connected to yourself and others by Socializing
