If you meditate, your body will thank you as much as your mind – starting with your heart.
It covers many of the diverse physical benefits of meditation including on your heart and cardiovascular system; blood pressure; and overall physical health markers.
Physical Benefits of Meditation: Heart, Blood, And Beyond
Transcendental or mantra meditation is more effective than other relaxation techniques (e.g., muscle relaxation) or education on lifestyle modification (e.g., diet and exercise strategies) at reducing blood pressure and likelihood of death from heart disease and all other causes.[[xv], [xvi]
Meditation consistently proves effective at lowering blood pressure, sometimes more so than other non-pharmacological treatments. And devoting just ten minutes twice a day to mindfulness meditation can significantly reduce blood pressure after 12 weeks of practice.[[xvii]]
Meditation improves other cardiovascular and metabolic disease risk factors as well.
Numerous studies have found improvements in blood lipid profiles and blood glucose control, and consequent reduced risks of diabetes and heart disease, with meditation practice of varying lengths and types.[[xviii], [xix]]
So, what’s happening here? Why does meditation have such a strong impact on your physical body?
These changes are largely the body’s way of giving thanks for freedom from stress! Psychological stress increases resting heart rate, elevates blood pressure, and causes widespread inflammation and oxidative damage in cells, artery walls, and body organs. [[xx]]
Stress hormones like epinephrine and cortisol contribute significantly to this damage. Cortisol wreaks general havoc in the body as it readies our organ systems for an attack from the unlikely wolf encountered in the woods—but for many sufferers of chronic disease living in modern society, the hormone never lets up.
Prolonged elevation of cortisol levels is linked to hypertension, hyperglycemia, abdominal obesity, increased appetite and cravings for sugary foods, and a suppressed immune system, among other abnormalities.[[xxi]]
In other words, stress damages the body in dozens of ways, and research frequently points to the stress-reducing effect of mediation as the predominant mechanism for its beneficial impact on physical health.[[xxii]]
Meditation vs. Stress and Inflammation
Inflammation is one of the big problems in your body that the Bulletproof Diet is designed to manage and reduce, and meditation helps with this too.
Stress and inflammation go hand-in-hand in when it comes to doing the body harm. Various forms of meditation, including mindfulness meditation, yoga, tai chi, and qigong, have been shown to reduce levels of inflammatory proteins and signaling factors implicated in chronic disease, notably the markers C-reactive protein, interleukin-6, and tumor necrosis factor-alpha.[[xxiii]]
These pro-inflammatory molecules can significantly weaken the immune system, and meditation counters this effect. Meditation also improves immunologic memory, prompting faster production of antibodies to combat viruses and prevent infection.[[xxiv]]
Meditation and Immune Function
It’s widely acknowledged that the brain and central nervous system play a large role in regulating immune function, especially in response to stress; thus meditation may again impact physical health via changes to stress-reduction pathways in the brain.
Of note: a randomized controlled trial linked changes in brain activation in an area associated with elevated immune activity directly to antibody levels to the influenza virus in a group of mindfulness meditation practitioners.[[xxv]]
Because of these improvements in physical health, meditation is now counted among the effective therapies for a wide range of diseases including cancer, heart disease, diabetes, and autoimmune disorders, for which the “classic treatment” is usually a host of semi-effective pharmaceutical drugs and resignation to an unhappy, sickly future.
A few minutes of meditation a day, or even several times a week, seems an easy investment in comparison.
Consistency Is Key
As the above information hopefully convinced you, at the very least a consistent daily meditation practice can go a long way toward upgrading your performance and managing your stress.
