Mindfulness Meditation Is Good for Your Health-

Research suggests that mindfulness benefits our bodies, not just our minds.

According to thousands of years of tradition, Buddhists meditate to understand themselves and their connections to all beings. By doing so, they hope to be released from suffering and ultimately gain enlightenment.

 In recent decades, researchers have been gaining insight into the benefits of practicing this ancient tradition. By studying more secular versions of mindfulness meditation, they’ve found that learning to pay attention to our current experiences and accept them without judgment might indeed help us to be happier. Studies to date suggest that mindfulness affects many aspects of our psychological well-being—improving our mood, increasing positive emotions, and decreasing our anxiety, emotional reactivity, and job burnout.

But does mindfulness affect our bodies as well as our minds?

Recently, researchers have been exploring this question—with some surprising results. While much of the early research on mindfulness relied on pilot studies with biased measures or limited groups of participants, more recent studies have been using less-biased physiological markers and randomly controlled experiments to get at the answer. Taken together, the studies suggest that mindfulness may impact our hearts, brains, immune systems, and more.

Though nothing suggests mindfulness is a standalone treatment for disease nor the most important ingredient for a healthy life, here are some of the ways that it appears to benefit us physically.

Mindfulness is good for our hearts

Heart disease is the leading killer in the United States, accounting for about 1 in 4 deaths every year. So, whatever decreases the risks or symptoms of heart disease would significantly impact society’s health. Mindfulness may help with that.

In one study, people with pre-hypertension were randomly assigned to augment their drug treatment with either a course in mindfulness meditation or a program that taught progressive muscle relaxation. Those who learned mindfulness had significantly greater reductions in their systolic and diastolic blood pressure than those who learned progressive muscle relaxation, suggesting that mindfulness could help people at risk for heart disease by bringing blood pressure down.

In another study, people with heart disease were randomly assigned to either an online program to help them practice meditation or to a waitlist for the program while undergoing normal treatment for heart disease. Those who took the mindfulness program showed significant improvements on the six-minute walking test (a measure of cardiovascular capacity) and slower heart rates than those in the waitlist group.

While one review of randomly controlled studies showed that mindfulness may have mixed effects on the physical symptoms of heart disease, a more recent review published by the American Heart Association concluded that, while research remains preliminary, there is enough evidence to suggest mindfulness as an adjunct treatment for coronary disease and its prevention. 

Mindfulness may also be good for hearts that are already relatively healthy. Research suggests that meditating can increase respiratory sinus arrhythmia, the natural variations in heart rate that happen when we breathe that indicate better heart health and an increased chance of surviving a heart attack.

Mindfulness may decrease cognitive decline from aging or Alzheimer’s

People tend to lose some of their cognitive flexibility and short-term memory as they age. But mindfulness may be able to slow cognitive decline, even in people with Alzheimer’s disease.

In a 2016 study, people with Alzheimer’s disease engaged in either mindfulness meditation, cognitive stimulation therapy, relaxation training, or no treatment, and were given cognitive tests over two years. While cognitive stimulation and relaxation training seemed to be somewhat beneficial in comparison to no treatment, the mindfulness training group had much more robust improvements on cognitive scores than any other group.

Why might that be true? A 2017 study looking at brain function in healthy, older adults suggests meditation may increase attention. In this study, people 55 to 75 years old spent eight weeks practicing either focused breathing meditation or a control activity. Then, they were given the Stroop test—a test that measures attention and emotional control—while having their brains monitored by electroencephalography. Those undergoing breath training had significantly better attention on the Stroop test and more activation in an area of the brain associated with attention than those in the active control group.

While this research is preliminary, a systematic review of research to date suggests that mindfulness may mitigate cognitive decline, perhaps due to its effects on memory, attention, processing, and executive functioning.

Mindfulness may improve your immune response

When we encounter viruses and other disease-causing organisms, our bodies send out troops of immune cells that circulate in the blood. These cells, including pro- and anti-inflammatory proteins, neutrophils, T-cells, immunoglobulins, and natural killer cells, help us to fight disease and infection in various ways. Mindfulness, it turns out, may affect these disease-fighting cells.

In several studies, mindfulness meditation appeared to increase levels of T-cells or T-cell activity in patients with HIV or breast cancer. This suggests that mindfulness could play a role in fighting cancer and other diseases that call upon immune cells. Indeed, in people suffering from cancer, mindfulness appears to improve a variety of biomarkers that might indicate progression of the disease. 

In another study, elderly participants were randomly assigned to an eight-week Mindfulness-Based Stress Reduction (MBSR) course or a moderate-intensity exercise program. At the end, participants who’d practiced mindfulness had higher levels of the protein interleukin-8 in their nasal secretions, suggesting improved immune function.

Another study found increases in interleukin-10 in colitis patients who took a mindfulness meditation course compared to a mind-body educational program, especially among patients whose colitis had flared up. Yet another study found that patients who had greater increases in mindfulness after an MBSR course also showed faster wound healing, a process regulated by the immune system.

Studies have found effects on markers of inflammation, too—like C-reactive protein, which in higher levels can harm physical health. Research shows that people with rheumatoid arthritis have reduced C-reactive protein levels after taking an MBSR course versus being on a waitlist for the course. Overall, these findings suggest that mindfulness meditation can have disease-fighting powers through our immune response.

Mindfulness may reduce cell aging

Cell aging occurs naturally as cells repeatedly divide over the lifespan and can also be increased by disease or stress. Proteins called telomeres, which are found at the end of chromosomes and serve to protect them from aging, seem to be impacted by mindfulness meditation.
