How often do you sit still and do absolutely nothing.The usual answer these days is“never”.or“hardly ever”.As the pace of life continues to increase,we are fast losing the art of relaxation.Once you are in the habit of rushing through life,being on the go from morning till night,it is hard to slow down.But relaxation is essential for a healthy mind and body.

The amount of stress a person can withstand depends very much on the individual.Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities.Others lose heart at the first sight of unusual difficulties.When exposed to stress,in whatever form,we react both chemically and physically.In fact we make a choice between “fight” or “fright” and in more primitive days the choice made the difference between life and death.The crisis we meet today are unlikely to be so extreme,but however little the stress,it involves the same response.All the energy is shifted to cope with the stress.It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.
