During a state of deep relaxation, several physiological changes take place in the body: the body’s oxygen consumption is reduced; the heart beat decreases; muscle tension and sweating ease, and there is decreased sympathetic （交感的） nervous system activity．This restful state not only allows the body to repair and restore itself, but it has a calming effect on the consciousness．

How to achieve this state of relaxation, however, is a matter of opinion, and in some medical circles, a matter of controversy．A recent report by Dr．David Holmes of the University of Kansas in the journal “American psychologist” said that simply sitting in an armchair has just as many beneficial characteristics for the body as meditation （冥想） does．Researchers of other relaxation techniques disagree．These experts believe that more structured techniques, such as meditation, lead to a condition of deep relaxation．

The debate goes on, but one thing appears to be clear: the relaxation response can be reached by a number of methods, and the methods themselves are not as important as getting there．One day, one method may work best; on another day, an alternative method may be more appropriate．Once you are aware of all the methods, you can find the one that works best on you．

Some of the relaxation techniques are meditation, auto analysis and progressive muscle relaxation response．More than just sitting quietly in a chair, they have the added benefit of structure and discipline, and for these reasons appear to be more effective for most individuals．
