Brain Benefits of Exercise

drstaceynaito Leave a comment

Regular physical exercise is one of the most effective ways to support long-term brain health. Research across neuroscience, aging, and psychology consistently shows that exercise benefits memory, attention, mood, learning, and resilience against cognitive decline.

How Exercise Benefits the Brain

1. Improves Memory and Learning

Exercise increases blood flow to the brain, delivering more oxygen and nutrients. It also stimulates the release of growth factors such as BDNF (brain-derived neurotrophic factor), which helps neurons grow and form stronger connections.

Areas especially affected include the hippocampus, a region critical for memory formation. Studies show that people who exercise regularly often perform better on tasks involving:

  • Learning new information
  • Recall and retention
  • Processing speed
  • Mental flexibility

Even moderate aerobic exercise like brisk walking has been associated with improved memory performance.

2. Helps Preserve Cognitive Function With Age

One of the strongest findings in brain-health research is that consistent exercise helps slow age-related cognitive decline.

Regular physical activity is associated with:

  • Lower risk of dementia
  • Reduced risk of Alzheimer’s disease
  • Better executive functioning in older adults
  • Slower shrinkage of brain volume over time

Exercise appears to protect the brain through several mechanisms:

  • Improved circulation
  • Reduced inflammation
  • Better glucose regulation
  • Enhanced vascular health
  • Increased neural plasticity

The key factor is consistency. The brain benefits of exercise accumulate over years. Sporadic workouts help temporarily, but long-term habits are what appear to preserve cognitive function most effectively.

3. Supports Attention and Executive Function

Exercise strengthens executive functions — the mental skills used for:

  • Planning
  • Decision-making
  • Focus
  • Self-control
  • Multitasking

Physical activity increases activity and connectivity in the prefrontal cortex, which governs these higher-order functions.

This is one reason exercise is often linked to:

  • Better academic performance
  • Improved workplace productivity
  • Greater emotional regulation
  • Reduced mental fatigue

4. Enhances Mood and Mental Health

Exercise affects neurotransmitters involved in mood regulation, including:

  • Dopamine
  • Serotonin
  • Norepinephrine
  • Endorphins

Regular activity can reduce symptoms of:

  • Anxiety
  • Depression
  • Chronic stress

Exercise also lowers cortisol levels and improves sleep quality, both of which strongly influence cognitive performance and emotional resilience.

5. Promotes Neuroplasticity

The brain remains adaptable throughout life, and exercise helps maintain this adaptability.

Neuroplasticity refers to the brain’s ability to:

  • Form new neural pathways
  • Recover from injury
  • Adapt to new experiences
  • Learn new skills

Aerobic exercise in particular promotes neurogenesis — the formation of new neurons — especially in memory-related regions.

This means exercise does not simply “maintain” the brain; it actively supports the brain’s capacity to change and grow.

Why Consistency Matters More Than Intensity

A major misconception is that only intense athletic training benefits the brain. In reality, regular moderate activity performed consistently is extremely effective.

Examples include:

  • Walking
  • Cycling
  • Swimming
  • Dancing
  • Jogging
  • Resistance training
  • Sports with coordination and strategy

The brain responds especially well to routines maintained over months and years.

Consistency matters because:

  • Neural adaptations develop gradually
  • Blood vessel health improves over time
  • Inflammation reduction is cumulative
  • Protective effects against cognitive decline build slowly

Even relatively small amounts of weekly exercise can produce measurable brain benefits when sustained long term.

Exercise and Brain Aging

People who remain physically active throughout adulthood often show:

  • Better preserved white matter integrity
  • Stronger connectivity between brain regions
  • Larger hippocampal volume
  • Better reaction time and reasoning ability later in life

Exercise is increasingly viewed as a foundational preventive strategy for healthy cognitive aging — alongside sleep, nutrition, social engagement, and intellectual stimulation.

Types of Exercise That Benefit the Brain

Different forms of exercise appear to support the brain in complementary ways:

Aerobic Exercise

Most strongly linked to:

  • Memory
  • Cardiovascular support for the brain
  • Reduced dementia risk

Examples:

  • Running
  • Fast walking
  • Cycling
  • Swimming

Strength Training

Associated with:

  • Executive function
  • Attention
  • Functional independence with aging

Coordination-Based Activities

Activities like dancing, martial arts, or racquet sports challenge both body and mind simultaneously, engaging:

  • Spatial awareness
  • Timing
  • Reaction speed
  • Motor planning

Mind-Body Exercise

Yoga and tai chi may improve:

  • Stress regulation
  • Attention
  • Emotional balance
  • Cognitive flexibility

The Broader Brain Health Picture

Exercise works best as part of a broader brain-health lifestyle that includes:

  • Adequate sleep
  • Nutritious diet
  • Social connection
  • Lifelong learning
  • Stress management

Still, among lifestyle interventions, exercise is one of the most consistently supported by scientific evidence for preserving brain function across the lifespan.

A physically active lifestyle does not guarantee immunity from neurological disease, but it substantially improves the odds of maintaining cognitive vitality, emotional resilience, and functional independence into older age.

Scented Candle Love

A new favorite, Bergamot Tangerine from APOTHEKE

Luxury scented candles have a special way of enhancing a space that goes beyond just fragrance. They offer an affordable touch of indulgence—unlike many other luxury items, a well-made candle can be had without breaking the bank, yet it delivers a surprisingly rich sensory experience. As someone who enjoys scented candles from brands such as Voluspa, Archipelago Botanicals, APOTHEKE, and Nest, I know firsthand how affordable they are, as well as how much joy they bring me.

When lit, scented candles create an immediate shift in ambience. The flickering flame casts a soft, warm light that’s both calming and flattering, making any room feel more intimate and inviting. The scent adds another layer—evoking emotions, memories, or simply providing a gentle background aroma that makes a space feel cared for and curated. Whether it’s a woodsy blend, burst of fruit, or a complex and inviting floral, the right fragrance can transform a mundane evening into a soothing ritual. I light candles on a daily basis, and base my candle selection on what kind of mood I am in, as well as what kind of weather we are experiencing. For example, today was a warm, sunny day, so I opted for a refreshing grapefruit candle, and since it was in a smaller vessel, I opted to place it on my candle warmer instead of lighting it. Later tonight, after it gets dark, I will light a candle which fits my mood, settle onto the sofa in the living room, and enjoy the beautiful glow and inviting fragrance of the lit candle.

There’s also a practical bonus: by using candles for light, especially in the evening, you can reduce reliance on harsh electric lighting. This not only contributes to a more relaxing atmosphere but also supports energy conservation. It’s a small but meaningful gesture toward sustainability—proof that luxury and eco-consciousness don’t have to be at odds.

Check out this interesting website I found, which enables you to customize soothing sounds which you can use as a nice background or “white-noise” experience:

https://asoftmurmur.com/

The dashboard for A Soft Murmur, which is available as an app for both iOS and Android, allows you to adjust the volume or omit different nature or soothing sounds: waves, rain, wind, thunder, fire, birds, crickets, singing bowl, white noise, or coffee shop. For example, combining rain and thunder sounds will mimic a thunder storm. If you choose to upgrade to their premium plan, you can then access 13 more sounds, and have access to any new sounds as they are added to the app.

Two Breaths

Regular meditation practice has shaped my life for the past eleven years, and I honor and value all it has bestowed upon me in terms of balance, harmony, calmness and peace. When I began practicing meditation on a consistent basis, I was at a low point in my life as a result of a long-term relationship which had suddenly terminated. As fate would have it, I met a wonderful person who became my meditation teacher, my spiritual guide, and my dear friend. He invited me to become part of a local meditation group which met one to two times per week, and I gladly accepted. Within a couple of months, I began to learn how to sit in silence, let thoughts and feelings go, and focus on being completely in the moment. I quickly realized what a gift it was to fall into awareness during these sessions.

After my meditation teacher passed away in April of 2014, I went through a rough period in which I was so grief-stricken by his death that I was paralyzed, unable to meditate for several months. When I returned to meditation practice, it was alone, without the comfort of a group, but I was able to quickly fall into awareness during my sessions.

At the beginning of this year, I encountered another difficult life challenge, and instead of shying away from my meditation practice, I decided to sit daily. One tool which kept me accountable with daily meditation practice was a phone app called Insight Timer, which I still use. It is no longer a struggle for me to sit daily in meditation, and I have noticed profound changes in my demeanor and my general outlook on life.

In an effort to fortify my spiritual practice, I added kundalini yoga, and have noticed even more profound changes in my energy and my physiology, especially in my breathing. A few days ago, I had noticed that my respiratory rate had become much slower, so I decided to assess it while I practiced relaxation breathing. I was astonished when I discovered that I am now able to slow down my breathing to two respirations per minute. The breaths which I take during meditative and relaxation sessions are very slow, with a pause at the end of both the inhalation and exhalation phases.

Most people are so accustomed to shallow respirations in their daily lives that they assume that 12 to 14 respirations per minute is considered acceptable. As a physician, I regularly encounter a respiratory rate in that range, and am trained to consider that normal. However, in my spiritual practice, I know that in order to take 12 to 14 breaths per minute, the breaths tend to be quite shallow.

Modern society keeps us on the hamster wheel and fosters anxiety, but it is vital to step off the wheel, slow down, and allow the trappings of daily life to fall away so that we can truly let go. If you find yourself constantly wound up, try slowing down your breathing on a consistent basis. It has beneficial effects on your mood and blood pressure, and decreases muscle tension.

Sit Up Straight!

If you have a tendency to slouch in your seat, you need to pay attention! Poor posture has detrimental effects not only on the body, but also on one’s mood and general attitude.

Poor posture causes muscles in our neck and upper back to become overstretched, while causing other neck muscles and muscles in our torso and between our ribs to become cramped and overstimulated. The muscles in our chest become dominant, and pull our shoulders and upper arms inward and forward when we habitually adopt a stooped posture. This position puts a tremendous load on the diaphragm, and respiration suffers as a result. Even digestion becomes sluggish because the body cannot properly oxygenate and blood cannot circulate as well.

Poor posture can negatively impact your emotional state and confidence, not to mention how others perceive you. If you’re slouching right now, think of how you feel emotionally, mentally. Are you down, depressed? Now sit up straight and take a couple of nice, deep breaths. You should notice an immediate shift in attitude and mood.

Proper spinal alignment also has a positive effect on hormone levels. One Harvard study revealed that an erect posture, with shoulders back and spines nice and straight correlated with a 20 percent increase in testosterone levels and a 25 percent decrease in cortisol levels, while subjects who slouched experienced a 10 percent decrease in circulating testosterone levels and a 15 increase in cortisol.

Lastly, the way you carry yourself has immense bearing on how others perceive you. If you meet someone whose shoulders are pulled forward, your impression may be that the person isn’t the most motivated or energetic you’ve met. Yet if that person had a nice upright stance, with shoulders pulled down and back, your impression would probably be very different.

With some conscious effort, you can correct a hunched posture. Try this stretch at least a couple of times each day, and you will slowly begin to notice a correction in your posture. This is great for resetting the brain and creating more awareness of how you carry your body throughout the day.


AGAINST THE WALL

Stand with your back to a wall, feet together with heels touching wall, and arms hanging at your sides. Relax your shoulders, then pull them back so that they make contact with the wall. Stand in this position for 30 to 60 seconds, taking slow, deep breaths.
When you are ready to step away from the wall, keep your shoulders in the same position. Be aware of how you are breathing, and how your back feels when your shoulders are kept back.

Why Zinc Is So Important

Here is an article which I wrote a few years ago and which still applies to general health:

Zinc is a vital mineral which is found in every tissue in the body due to its involvement in cell division. In the world of fitness and bodybuilding, zinc has a number of roles, including maintenance of normal hormonal levels, proper endocrine function, body composition, energy levels, optimal physical performance and protein synthesis. Thus it is crucial to maintain normal levels of zinc in the body when training or prepping for a competition.

Zinc is highly concentrated in meat, dairy and some seafood. This is why vegetarians most commonly suffer from zinc deficiency. So how can you tell if you suffer from a zinc deficiency? Common symptoms include an altered sense of taste which leads to cravings for sweets and salty foods. Other symptoms of zinc deficiency include low energy, infertility, low libido, memory problems, poor immunity and diarrhea.

A relatively easy way to test yourself to see if you are deficient in zinc is to do a taste test. Take 1 to 2 teaspoons of zinc sulfate (you can get this at health food stores) and add to a cup of water. If it tastes just like water, you are very zinc deficient. If you experience a slightly metallic taste, you are moderately zinc deficient. If it is strongly metallic and unpleasant, you most likely have normal zinc levels. Please bear in mind that this test is never as accurate as a blood test, but at least it will give you an idea of what your levels are.

For those of you who want to know the specific health benefits of zinc, here is a list of benefits.

Enhances Strength and Athletic Performance:

Zinc plays a major role in anabolic hormone production which makes it a key player in optimizing athletic performance and strength. When zinc levels in the body are normal, more growth hormone and insulin-like growth factor-1 is released, which result in enhanced muscle growth and performance. Researchers have also noted that zinc enhances the conversion rate of androstenedione to testosterone, which improve strength gains during the recovery phase.

Enhances Reproductive Health and Fertility in Both Men and Women:

The cells of the male prostate require an extremely high concentration of zinc for proper function. To give you an idea of how much zinc is necessary in the prostate, male prostate tissue requires ten times more zinc than other cells in the body for normal function. There is a correlation between low zinc levels in men and increased risk of developing prostate cancer and infertility. There is also evidence to support the link between low zinc levels and low libido. Another implication with low zinc levels is its importance in maintaining optimal testosterone levels. Men with low zinc also tend to have low testosterone, which puts them at greater risk of andropausal symptoms.

In women, proper levels of zinc are essential for egg maturation and ovulation. Zinc also optimizes utilization of estrogen and progesterone and regulates their levels. During pregnancy, zinc plays a vital role in ensuring proper cell division in the growing fetus and helps to prevent premature delivery.

Essential For Taste, Smell and Appetite:

Zinc activates areas in the brain that process information from taste buds in the mouth and olfactory cells in the nasal passages. In addition, levels of zinc in the plasma influence taste preference and appetite. Many programs which treat anorexics use zinc to revive taste and appetite.

Makes Skin, Hair and Nails Healthy:

Zinc accelerates skin cell renewal which is why it is commonly used in diaper rash creams, acne treatments and creams which are used to treat dermatitis. It has strong anti-inflammatory properties and has a soothing effect on rashes, burns and blisters. Some shampoos contain zinc to help prevent dandruff. What you may not know is that zinc is important for healthy hair and that low zinc levels can cause hair loss, dull and thin hair, and loss of pigmentation.

Essential For Vision:

Zinc is found in high concentrations in the retina, but this level declines with advancing age, precipitating age-related macular degeneration which is characterized by a partial or complete loss of vision. Zinc also has a protective effect against the development of cataracts and night blindness.

Supports Cardiovascular Health:

Zinc is vital to normal cardiovascular function. When levels of zinc are low, the endothelial layer in blood vessels becomes inflamed and accumulates cholesterol deposits, both of which increase one’s risk of heart disease. Low levels of zinc can amplify the negative cardiovascular effects of diets which are high in fat and cholesterol, whereas adequate levels of zinc will inhibit the progression of heart disease.

Increases Insulin Sensitivity:

The presence of zinc is essential for normal function of most hormones, including insulin. Zinc binds to insulin and aids in storage in the pancreas as well as release of insulin in the presence of serum glucose. In addition, zinc is found in the enzymes which enable insulin to bind to cells so that glucose can be utilized for fuel, a process better known as insulin sensitivity. Why is this important? If zinc levels are low, enzyme levels drop, insulin sercretion drops and glucose remains in the bloodstream, a process which can lead to diabetes if it is chronic.

Improves Mood:

Dopamine, a chemical in the brain which boosts mood and energy, is partially regulated by zinc, so zinc once again plays an important role in the body. There is also evidence to support the theory that the presence of zinc boosts serotonin levels in the brain.

Supports Immune Function:

Zinc supports T cell function and is thus strongly tied with combating inflammation. T cells are responsible for mounting an immune response to invaders such as bacteria or viruses.

Has Potent Antioxidant Effect:

Zinc can remove toxins from the body and prevent accumulation of harmful compounds in tissues. This mechanism has a protective effect against the development of cancers, especially in the prostate, ovaries, pancreas, breast and colon. In addition, zinc prevents the buildup of heavy metals in the brain such as aluminum, which has been closely linked with Alzheimer’s disease.

If you suspect that you are deficient in zinc, you can supplement daily with 20 to 30 milligrams.
