Meditation is a practice of concentrated focus upon a sound, object, visualization, the breath, movement, or attention itself in order to increase awareness of the present moment, reduce stress, promote relaxation, and enhance personal and spiritual growth.


Meditation techniques have been practiced for millennia. Originally, they were intended to develop spiritual understanding, awareness, and direct experience of ultimate reality. The many different religious traditions in the world have given rise to a rich variety of meditative practices. These include the contemplative practices of Christian religious orders, the Buddhist practice of sitting meditation, and the whirling movements of the Sufi dervishes. Although meditation is an important spiritual practice in many religious and spiritual traditions, it can be practiced by anyone regardless of their religious or cultural background to relieve stress and pain.

As Western medical practitioners begin to understand the mind's role in health and disease, there has been more interest in the use of meditation in medicine. Meditative practices are increasingly offered in medical clinics and hospitals as a tool for improving health and quality of life. Meditation has been used as the primary therapy for treating certain diseases, as an additional therapy in a comprehensive treatment plan, and as a means of improving the quality of life of people with debilitating, chronic, or terminal illnesses.


Meditation benefits people with or without acute medical illness or stress. People who meditate regularly have been shown to feel less anxiety and depression. They also report that they experience more enjoyment and appreciation of life and that their relationships with others are improved. Meditation produces a state of deep relaxation and a sense of balance or equanimity, creating a greater sense of calmness, empathy, and acceptance of self and others.

Meditation can be used with other forms of medical treatment and is an important complementary therapy for both the treatment and prevention of many stress-related conditions. Regular meditation can reduce the number of symptoms experienced by patients with a wide range of illnesses and disorders. Based upon clinical evidence as well as theoretical understanding, meditation is considered to be one of the better therapies for panic disorder, generalized anxiety disorder, substance dependence and abuse, ulcers, colitis, chronic pain, psoriasis, and dysthymic disorder. It is considered to be a valuable adjunctive therapy for moderate hypertension (high blood pressure), prevention of cardiac arrest (heart attack), prevention of atherosclerosis (hardening of arteries), arthritis (including fibromyalgia), cancer, insomnia, migraine, and prevention of stroke. Meditation may also be a valuable complementary therapy for allergies and asthma because of the role stress plays in these conditions. Meditative practices have been reported to improve function or reduce symptoms in patients with some neurological disorders as well. These include people with Parkinson's disease, people who experience fatigue with multiple sclerosis, and people with epilepsy who are resistant to standard treatment.

A 1995 report to the National Institutes of Health on alternative medicine concluded that, “More than 30 years of research, as well as the experience of a large and growing number of individuals and healthcare providers, suggests that meditation and similar forms of relaxation can lead to better health, higher quality of life, and lowered healthcare costs …” In the years since then, groups such as the National Center for Complementary and Integrative Health (NCCIH), part of the National Institutes of Health (NIH), have done research on meditation applied to a number of specific conditions, such as fibromyalgia, multiple sclerosis, and post traumatic stress disorder. In the 2010s, studies found that meditation improved pain, anxiety and depression, high blood pressure, and irritable bowel syndrome. Meditation appeared to be a promising aid to people attempting to quit smoking. Even in cases where the treatment benefits of meditation are not clear, the practice is generally considered safe for healthy people.


Sitting meditation is generally done in an upright seated position, either in a chair or cross-legged on a cushion on the floor. The spine is straight yet relaxed. Sometimes the eyes are closed. Other times the eyes are open and gazing softly into the distance or at an object. Depending on the type of meditation, the meditator may be concentrating on the sensation of the movement of the breath, counting the breath, silently repeating a sound, chanting, visualizing an image, focusing awareness on the center of the body, opening to all sensory experiences including thoughts, or performing stylized ritual movements with the hands.

Movement meditation can be spontaneous and freeform or involve highly structured, choreographed, repetitive patterns. Movement meditation is particularly helpful for those people who find it difficult to remain still.

Generally speaking, there are two main types of meditation: concentration meditation and mindfulness meditation. Many meditation practices are a blend of these two forms.

Concentration meditation practices involve focusing attention on a single object. Objects of meditation can include the breath, an inner or external image, a movement Page 2258  |  Top of Articlepattern (as in tai chi or yoga), or a sound, word, or phrase that is repeated silently (mantra). The purpose of concentrative practices is to learn to focus one's attention or develop concentration. When thoughts or emotions arise, the meditator gently directs the mind back to the original object of concentration.

Mindfulness meditation practices involve becoming aware of the entire field of attention. The meditator is instructed to be aware of all thoughts, feelings, perceptions, or sensations as they arise in each moment. Mindfulness meditation practices are enhanced by the meditator's ability to focus and quiet the mind.

The study and application of meditation to healthcare has focused on three specific approaches: transcendental meditation (TM); the “relaxation response,” a general approach to meditation developed by Dr. Herbert Benson; and mindfulness meditation, specifically the program of mindfulness-based stress reduction (MBSR) developed by Jon Kabat-Zinn.

Transcendental meditation (TM)

TM has its origins in the Vedic tradition of India and was introduced to the West by Maharishi Mahesh Yogi. TM has been taught to somewhere between two and four million people. It is one of the most widely practiced forms of meditation in the West. TM has been studied many times; these studies have produced much of the information about the physiology of meditation. In TM, the meditator sits with closed eyes and concentrates on a single syllable or word (mantra) for 20 minutes at a time, twice a day. When thoughts or feelings arise, the attention is brought back to the mantra. According to TM researcher Charles Alexander, “During TM, ordinary waking mental activity is said to settle down, until even the subtlest thought is transcended and a completely unified wholeness of awareness… is experienced. In this silent, selfreferential state of pure wakefulness, consciousness is fully awake to itself alone …” TM supporters believe that TM practices are more beneficial than other meditation practices.

The relaxation response

The relaxation response involves a similar form of mental focusing. Dr. Herbert Benson, one of the first Western doctors to conduct research on the effects of meditation, developed this approach after observing the profound health benefits of a state of bodily calm he calls “the relaxation response.” In order to elicit this response in the body, patients are taught to focus upon the repetition of a word, sound, prayer, phrase, or movement activity (including swimming, jogging, yoga, and even knitting) for 10–20 minutes at a time, twice a day. Patients are also taught not to pay attention to distracting thoughts and to return their focus to the original repetition. The choice of the focused repetition is up to the individual. Instead of Sanskrit terms, the meditator can choose what is personally meaningful, such as a phrase from a Christian or Jewish prayer.

Mindfulness meditation

Mindfulness meditation comes out of traditional Buddhist meditation practices. Psychologist Jon Kabat-Zinn has been instrumental in bringing this form of meditation into medical settings. In formal mindfulness practice, the meditator sits with eyes closed, focusing the attention on the sensations and movement of the breath for approximately 45–60 minutes at a time, at least once a day. Informal mindfulness practice involves bringing awareness to every activity in daily life. Wandering thoughts or distracting feelings are simply noticed without resisting or reacting to them. The essence of mindfulness meditation is not what one focuses on but rather the quality of awareness the meditator brings to each moment. According to Kabat-Zinn, “It is this investigative, discerning observation of whatever comes up in the present moment that is the hallmark of mindfulness and differentiates it most from other forms of meditation. The goal of mindfulness is for you to be more aware, more in touch with life and whatever is happening in your own body and mind at the time it is happening—that is, the present moment.” The MBSR program consists of a series of classes involving meditation, movement, and group process. There are MBSR programs offered in healthcare settings around the world.

Meditation is not considered a medical procedure or intervention by most insurers. Many patients pay for meditation training themselves. Frequently, religious groups or meditation centers offer meditation instruction free of charge or for a nominal donation. Hospitals may offer MBSR classes at a reduced rate for their patients and a slightly higher rate for the general public.


Meditation appears to be safe for most people. There are, however, case reports and studies noting some adverse effects. Thirty-three to 50% of the people participating in long, silent meditation retreats (two weeks to three months) reported increased tension, anxiety, confusion, and depression. On the other hand, most of these same people also reported very positive effects from their meditation practice. Kabat-Zinn notes that these studies fail to differentiate between serious psychiatric disturbances and normal emotional mood swings. These studies do suggest, however, that meditation may not be recommended for people with psychotic Page 2259  |  Top of Articledisorders, severe depression, and other severe personality disorders unless they are also receiving psychological or medical treatment.

Side effects

There are no reported side effects from meditation except for positive benefits.

Research and general acceptance

The scientific study of the physiological effects of meditation began in the early 1960s. These studies prove that meditation affects metabolism, the endocrine system, the central nervous system, and the autonomic nervous system. In one study, three advanced practitioners of Tibetan Buddhist meditation practices demonstrated the ability to increase “inner heat” as much as 61%. During a different meditative practice they were able to dramatically slow down the rate at which their bodies consumed oxygen. Preliminary research shows that mindfulness meditation is associated with increased levels of melatonin. These findings suggest a potential role for meditation in the treatment and prevention of breast and prostrate cancer.

Despite the inherent difficulties in designing research studies, there is a large amount of evidence of the medical benefits of meditation. Meditation is particularly effective as a treatment for chronic pain. Studies have shown meditation reduces symptoms of pain and pain-related drug use. In a four-year follow-up study, the majority of patients in a MBSR program reported “moderate to great improvement” in pain as a result of participation in the program.

Meditation has long been recommended as a treatment for high blood pressure; however, there is a debate over the amount of benefit that meditation offers. Although most studies show a reduction in blood pressure with meditation, medication is still more effective at lowering high blood pressure.

Meditation may be an effective treatment for coronary artery disease. A study of 21 patients practicing TM for eight months showed increases in their amount of exercise tolerance, amount of workload, and a delay in the onset of ST-segment depression.

Research also suggests that meditation is effective in the treatment of chemical dependency. Gelderloos and others reviewed 24 studies and reported that all of them showed that TM is helpful in programs to stop smoking and also in programs for drug and alcohol abuse.

In 2015, the Benson-Henry Institute for Mind Body Medicine at Massachusetts General Hospital published research finding that mindfulness programs reduced doctors visits by 43%.

Studies suggest that meditation is helpful in reducing symptoms of anxiety and in treating anxiety-related disorders. A study in 1998 of 37 psoriasis patients showed that those practicing mindfulness meditation had more rapid clearing of their skin condition, with standard UV light treatment, than the control subjects. Another study found that meditation decreased the symptoms of fibromyalgia; over half of the patients reported significant improvement. Meditation was one of several stress management techniques used in a small study of HIVpositive men. The study showed improvements in the Tcell counts of the men, as well as in several psychological measures of well-being. A 2014 study found that meditation helped reduce stress in patients being treated for breast cancer, and a 2013 study found that meditation was more effective than music therapy, education about diet, and physical activity at reducing stress-induced inflammation.

Training and certification

There is no program of certification or licensure for instructors who wish to teach meditation as a medical therapy. Meditation teachers within a particular religious tradition usually have extensive experience and expertise with faith questions and religious practices but may not have been trained to work with medical patients. Different programs have varied requirements for someone to teach meditation. In order to be recognized as an instructor of TM, one must receive extensive training. The Center for Mindfulness in Medicine, Health Care and Society at the University of Massachusetts Medical Center offers training and workshops for health professionals and others interested in teaching mindfulness-based stress reduction. The Center does not, however, certify that someone is qualified to teach meditation. The University of Pennsylvania program for Stress Management suggests that a person have at least ten years of personal experience with the practice of mindfulness meditation before receiving additional instruction to teach meditation. Teachers are also expected to spend at least two weeks each year in intensive meditation retreats.
