     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 lift, being on the go from morning till night, it is hard to slow down. But relaxation

is essential for a healthy mind and body.                              

     Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it

is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life.

It is only when the stress gets out of control that it can lead to poor performance and ill healthy.              

     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 signs of unusual difficulties. When exposed to stress, in whatever form, we

react both chemically and physically. In fact we make choice between "fight" or "flight" and in more

primitive days the choice made the difference between life or death. The crises we meet today are

unlikely to be so extreme, but however little the stress is, it involves the same response. 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. Since we

cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find

ways to deal with it.
