Improve Hypertension with Mindfulness Training
By John M. de Castro, Ph.D.
“Several practices that help calm the mind can also lower blood pressure. All are types of meditation, which use different methods to reach a state sometimes described as “thoughtful awareness” or “restful alertness.” – Harvard Health
High Blood Pressure (Hypertension) is an insidious disease because there are no overt symptoms. The individual feels fine. But it can be deadly as more than 360,000 American deaths, roughly 1,000 deaths each day, had high blood pressure as a primary or contributing cause. In addition, hypertension markedly increases the risk heart attack, stroke, heart failure, and kidney disease. It is also a very common disorder with about 70 million American adults (29%) having high blood pressure and only about half (52%) of people with high blood pressure have their condition under control. Treatment frequently includes antihypertensive drugs. But these medications often have adverse side effects. So, patients feel lousy when taking the drugs, but fine when they’re not. So, compliance is a major issue with many patients not taking the drugs regularly or stopping entirely.
Obviously, there is a need for alternatives to drugs for reducing blood pressure. Mindfulness practices have been shown to aid in controlling hypertension. There has accumulated a body of research on the ability of Mindfulness practices to affect hypertension. So, it makes sense to summarize what has been learned.
In today’s Research News article “Is Mindfulness-Based Stress Reduction Effective for People with Hypertension? A Systematic Review and Meta-Analysis of 30 Years of Evidence.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8000213/ ) Conversano and colleagues review, summarize and perform a meta-analysis of the published research studies of the effectiveness of mindfulness training on hypertension. They identified 6 published studies that employed either Mindfulness-Based Stress Reduction (MBSR) (3 studies), Mindfulness-Based Cognitive Therapy (MBCT) (2 studies), and mindfulness meditation (1 study).
They report that the published research found that mindfulness training improved hypertension with reductions in both systolic and diastolic blood pressure. They further report that mindfulness training worked best when the number of patients taking antihypertensive drugs were low, with the lower the percentage of participants on antihypertensive drugs, the greater the effect size of mindfulness training on hypertension.
These are impressive results that suggest that mindfulness training is a safe and effective treatment for hypertension. The trainings appear to work best in the absence of drugs to control hypertension. It follows that mindfulness training would reduce the physical effects of hypertension and thereby improve the overall health and longevity of the patients.
So, improve hypertension with mindfulness training.
“The hope is that if we can start mindfulness training early in life, we can promote a trajectory of healthy aging across the rest of people’s lives. That will reduce their chances of getting high blood pressure in the first place.” – Eric Loucks

Abstract
Background: Hypertension is among the most important risk factors for cardiovascular diseases, which are considered high mortality risk medical conditions. To date, several studies have reported positive effects of mindfulness-based stress reduction (MBSR) interventions on physical and psychological well-being in other medical conditions, but no meta-analysis on MBSR programs for hypertension has been conducted. Objectives: The objective of this study was to determine the effectiveness of MBSR programs for hypertension. Methods: A systematic review and meta-analysis of randomized controlled trials examining the effects of MBSR on systolic and diastolic blood pressure (BP), anxiety, depression, and perceived stress in people with hypertension or pre-hypertension was conducted. The PubMed/MEDLINE and PsycINFO databases were searched in November 2020 to identify relevant studies. Results: Six studies were included. The comparison of MBSR versus control conditions on diastolic BP was associated with a statistically significant mean effect size favoring MBSR over control conditions (MD = −2.029; 95% confidence interval (CI): −3.676 to −0.383, p = 0.016, k = 6; 22 effect sizes overall), without evidence of heterogeneity (I2 = 0.000%). The comparison of MBSR versus control conditions on systolic BP was associated with a mean effect size which was statistically significant only at a marginal level (MD = −3.894; 95% CI: −7.736–0.053, p = 0.047, k = 6; 22 effect sizes overall), without evidence of high heterogeneity (I2 = 20.772%). The higher the proportion of participants on antihypertensive medications was, the larger the effects of MBSR were on systolic BP (B = −0.750, z = −2.73, p = 0.003). Conclusions: MBSR seems to be a promising intervention, particularly effective on the reduction of diastolic BP. More well-conducted trials are required.
