How Exercise Helps Keep Your Brain Healthy

Regular exercise has a multitude of benefits—improved heart and lung capabilities, increased stamina, weight control, muscle toning, lower blood pressure—but one of the biggest benefits of physical activity is a major boost in brain function and memory retention. 

Several studies have shown exercise is just as good for your mind as it is for your body. Take a look at the specific biological benefits of a quick jog, bike ride or lap around the pool:

Increased Cognitive Function and Memory Retention

When you exercise, your heart rate increases, which increases blood flow to the brain. This brings more oxygen and nutrients to the brain, increasing the release of beneficial proteins that help keep your brain healthy, while also promoting the growth of new brain cells, or neurons. Neurons serve as the building blocks of the brain, and studies show their overall health helps contribute to increased focus, improved memory and decreased brain fog.

Reduced Stress and Anxiety

Moderate aerobic physical activity, like a brisk walk, jog, aerobics class or spin class, stimulates the brain’s release of endorphins, a “feel good” chemical that counteracts the body’s stress hormones and works as a natural mood booster and helps keep anxiety at bay. Consistent exercise encourages your brain to regularly release endorphins, which can contribute to long-term stress and anxiety reduction.

Improved Mood

Studies show that exercise releases additional mood-boosting chemicals, such as dopamine and serotonin. While these chemicals provide an immediate positive effect, they’re also contributing to a longer-term boost for your brain. Exercise helps create new neurons in the hippocampus region of the brain— the area associated with emotions, learning and memory— and can lead to more consistent emotional regulation and stability. Physical activity also contributes to better sleep, which in turn leads to a more positive and focused mental state.

How Much Exercise is Enough?

How much exercise is enough to experience the positive effects of brain function? Any amount of exercise is better than none, but experts say 150 minutes of moderate-impact aerobic exercise each week— whether that’s broken down into smaller 20 minute sessions a day, or hour-long sessions a few times a week, will yield brain-boosting results in both the short and long term.

Easy forms of exercise to incorporate into your daily life to boost brain health:

  • A brisk 15-30 minute walk
  • 15 minutes of low to moderate impact weight lifting (2-5 pound hand weights)
  • A 15-20 minute yoga or stretching session
  • Clean your home, play with a pet, wash your car or tend to a garden for 30 minutes or more

        “Punch-drunk syndrome” and the history of contact sports and brain damage

        Chronic traumatic encephalopathy, or CTE, was previously known as dementia pugilistica or “punch-drunk syndrome” for its association with former boxers demonstrating declining ability, memory loss, and lack of coordination. The hallmark risk factor that separates the syndrome from other tauopathies and dementias is repeated trauma to the head, otherwise known as traumatic brain injuries, or TBIs. It’s this repeated trauma where things become an issue for contact sports.

        The History of EEGs

        The field of electroencephalography began with the discovery of recordable electrical potentials from animals in the late 19th century, and in the 1920s, a neuropsychiatrist from Germany, Dr. Hans Berger, recorded the first potentials from human patients and created the procedure we know as the EEG.

        The Vagus Nerve: An explainer of the tenth cranial nerve and its clinical implications

        Vagus nerve stimulation is a treatment that has been occasionally used to treat epilepsy, treatment-resistant depression, and even Alzheimer’s dementia. Are you familiar with this unusual treatment? Are you familiar with the vagus nerve? Though it’s not commonly known, it’s a critical part of your nervous system and has many potential clinical implications. Let’s chat about the vagus nerve and vagus nerve stimulation, but first, some background and context.
