How much do we know about meditation?

 

Many studies have been conducted to look at how meditation may be helpful for a variety of conditions, such as high blood pressure, certain psychological disorders, and pain. A number of studies also have helped researchers learn how meditation might work and how it affects the brain.

 

What do we know about the effectiveness of meditation?

 

Some research suggests that practising meditation may reduce blood pressure, symptoms of irritable bowel syndrome, anxiety and depression, and insomnia. Evidence about its effectiveness for pain and as a smoking-cessation treatment is uncertain.

 

What do we know about the safety of meditation?

 

Meditation is generally considered to be safe for healthy people. However, people with physical limitations may not be able to participate in certain meditative practices involving movement.

What Is Meditation?

 

Meditation is a mind and body practice that has a long history of use for increasing calmness and physical relaxation, improving psychological balance, coping with illness, and enhancing overall health and well-being. Mind and body practices focus on the interactions among the brain, mind, body, and behaviour.

There are many types of meditation, but most have four elements in common: a quiet location with as few distractions as possible; a specific, comfortable posture (sitting, lying down, walking, or in other positions); a focus of attention (a specially chosen word or set of words, an object, or the sensations of the breath); and an open attitude (letting distractions come and go naturally without judging them).

What the Science Says About the Effectiveness of Meditation

 

Many studies have investigated meditation for different conditions, and there’s evidence that it may reduce blood pressure as well as symptoms of irritable bowel syndrome and flare-ups in people who have had ulcerative colitis. It may ease symptoms of anxiety and depression and may help people with insomnia.

Meditation and the Brain

 

Some research suggests that meditation may physically change the brain and body and could potentially help to improve many health problems and promote healthy behaviors.

What the Science Says About Safety and Side Effects of Meditation

 

  • Meditation is generally considered to be safe for healthy people.
  • People with physical limitations may not be able to participate in certain meditative practices involving movement. People with physical health conditions should speak with their health care providers before starting a meditative practice, and make their meditation instructor aware of their condition.
  • There have been rare reports that meditation could cause or worsen symptoms in people with certain psychiatric problems like anxiety and depression. People with existing mental health conditions should speak with their health care providers before starting a meditative practice, and make their meditation instructor aware of their condition.

NCCIH-Funded Research

 

NCCIH-supported studies are investigating meditation for:

  • Teens experiencing chronic, widespread pain, such as from fibromyalgia
  • Stress reduction for people with multiple sclerosis
  • Post-traumatic stress disorder, headaches, reducing blood pressure.

More to Consider

 

 

  • Don’t use meditation to replace conventional care or as a reason to postpone seeing a health care provider about a medical problem.
  • Ask about the training and experience of the meditation instructor you are considering.
  • Tell all your health care providers about any complementary or integrative health approaches you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care.
