We all know that exercise has a profound impact on the body, but what about the brain?

John F. Kennedy said, “Physical fitness is not only one of the most important keys to a healthy body, it is the basis of dynamic and creative intellectual activity.”

So, how does exercise impact our intellectual abilities?

You might be surprised to learn that there is a vital connection between physical activity and cognitive health. Exercise provides significant benefits for brain function including increased blood flow to the brain. This aids in additional oxygen and essential nutrients reaching the brain, which are both “important keys” for a strong intellectual activity. By incorporating regular exercise into our daily lives, the brain-derived neurotropic factor (BDNF) is released.

A protein, BDNF plays a big role in the survival, growth, and maintenance of nerve cells in both the brain and the spinal cord as well as affecting memory, processing speed, and the ability to learn. BDNF is another steppingstone along the path toward optimal cognitive health and function. Research shows that those who participate in consistent physical activity reap the rewards of protection against stroke and lowered risk of diseases such as Alzheimer’s, Parkinson’s, multiple sclerosis, and Huntington’s.

You may have noticed how your mood improves after engaging in physical activity. This is because exercise stimulates endorphins, the hormones responsible for reducing stress and boosting mood. Endorphins can also reduce symptoms of depression and anxiety, strengthen the immune system, and reduce inflammation. Activities including cycling, yoga, strength training, or a brisk walk can each provide a multitude of physical benefits as well as enhancing brain health and function. Exercise doesn’t have to be intense to be beneficial. Find ways to move your body that you enjoy and look forward to rather than activities that are strenuous or overwhelming, and you’ll set yourself up for success! Consider inviting a friend to go on regular walks or take a fitness class together. Having someone to encourage and hold you accountable when it comes to exercise can make all the difference. In addition, when you work out with someone, not only are you engaging in physical activity, but the social connection provides cognitive perks as well!

Of course, exercise requires fuel and energy, so you’ll want to ensure that you’re making nutritional choices that will benefit your efforts to engage in physical activity. Opting for protein and carbohydrates before exercising can provide a quick boost in energy and help with endurance. These carbs should be complex and come from whole grains like brown rice or quinoa, so be sure to avoid refined and processed foods when making your selections.

Another important aspect to consider when participating in physical activity is hydration. One of our favorite tips at AMFAS is to add a few pinches of Himalayan pink salt to our water and shake it up, replacing essential electrolytes and boosting hydration efforts.

Staying physically active might not be the first thing that comes to mind when considering ways to improve brain health, but it matters! With such a wide range of benefits, physical activity is one of the best things we can do for ourselves to improve our overall well-being.
