Meditation Research Studies
Physical and health benefits of meditation
Thanks to the many researchers for their contributions on the physical and health benefits of meditation. For many, meditation has proved to provide significant improvement in their health and well-being.
- In a study of health insurance statistics, meditators had 87% fewer hospitalizations for heart disease, 55% fewer for benign and malignant tumors, and 30% fewer for infectious diseases. The meditators had more than 50% fewer doctor visits than did non-meditators. (1)
- Meditation lowers blood pressure to levels comparable to prescription drugs for those who are normal to moderately hypertensive. (2)
- Meditation increases circulation in beginning meditators by 30%, and in experienced meditators by as much as 65%. (3)
- Meditation has endorsed by the NIH as effective for the relief of chronic pain. Chronic pain sufferers experience a reduction in symptoms of 50% or more. (4)
- 75% of long-term insomniacs who have been trained in relaxation, meditation, and simple lifestyle changes can fall asleep within 20 minutes of going to bed. (5)
- Meditation reduces blood sugar levels in diabetics. (6)
- A group of inner-city residents suffering from chronic pain, anxiety, depression, diabetes and hypertension were trained in meditation. They experienced a 50% reduction in overall psychiatric symptoms, a 70% decrease in anxiety, and a 44% reduction in medical symptoms. (7)
Mental and productivity benefits of meditation
Research on meditation has shown significant improvements in mental health, memory, concentration, and productivity.
- Brain scans show that meditation shifts activity in the prefrontal cortex (behind the forehead) from the right hemisphere to the left. People who have a negative disposition tend to be right-prefrontal oriented; left-prefrontals have more enthusiasms, more interests, relax more, and tend to be happier. (8)
- Researchers tested novice meditators on a button-pressing task requiring speed and concentration. Performance was greater at 40 minutes of meditation than after a 40-minute nap. (9)
- Meditation helps chronically depressed patients, reducing their relapse rate by half. (10)
- Meditators notice more, but react more calmly than non-meditators to emotionally arousing stimuli. (11)
- Those with smoking, alcohol, and eating addictions who have been trained in meditation break their addictions with significantly lower relapse rates than those receiving standard therapies. (12)
- Middle school children who practice meditation show improved work habits, attendance, and GPA. (13)
- Brain scans of meditators show increased thickness in regions of the cortex associated with higher functions like memory and decision making. (14)
- Meditation appears to slow aging. Those meditating five years or more were 12 years younger than their chronological age. (15)
