Does Meditation Work?

We've been told that meditation is good for us, but it's hard to pin down exactly why. Mediation causes shifts in the body, specifically its "fight or flight" response, which we use to protect ourselves. If the "fight or flight" response is occurring at inappropriate times, it may cause much distress, such as panic disorder and general anxiety...

The autonomic nervous system (sometimes called the involuntary nervous system) controls our fight or flight response. It regulates many organs and muscles, including functions such as the heartbeat, sweating, breathing, and digestion, and does so involuntarily.

The autonomic nervous system is divided into two parts:

* The sympathetic nervous system helps mobilize the body for action. When a person is under stress, it produces the fight-or-flight response: the heart rate and breathing rate go up, for example, the blood vessels narrow (restricting the flow of blood), and muscles tighten.

* The parasympathetic nervous system creates what some call the "rest and digest" response. This system's responses oppose those of the sympathetic nervous system. For example, it causes the heart rate and breathing rate to slow down, the blood vessels to dilate (improving blood flow), and activity to increase in many parts of the digestive tract.

Scientists are studying whether meditation has health benefits, they are also looking at how it may do so. One way some types of meditation might work is by reducing activity in the sympathetic nervous system and increasing activity in the parasympathetic nervous system.

Scientific research is using sophisticated tools to learn more about what goes on in the brain and the rest of the body during meditation, and diseases or conditions for which meditation might be useful. There is still much to learn in these areas. One avenue of research is looking at whether meditation is associated with significant changes in brain function. A number of researchers believe that these changes account for many of meditation's effects.
