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 (必要的)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 (有必要的) 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 health.
The amount of stress a person can stand depends very much on the person himself. Some people are not afraid of stress, and such characters are obviously important 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 "flight or fight" and in more early days the choices made the difference between life or death. The crises  (危机) we meet today are unlikely to be so extreme, but how 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 diseases 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.
