For many years doctors have warned us about the dangers of stress (压力) and have given us advice about how to cut down our stress levels. Everyone agrees that long-term stress, for example having to look after someone who has a chronic (慢性的) illness, or stressful situations where there is nothing we can do, for example being stuck in a traffic jam, should be avoided whenever possible. However, some medical experts now believe that certain kinds of stress may actually be good for us.
Dr Marios Kyriazis, an anti-ageing expert, points out that what he calls "good stress” is beneficial to our health and may, in fact, help us stay young and attractive and even live longer. Dr Kyriazis says that “good stress” can strengthen our natural defences which protect us from illnesses common among older people, such as Alzheimer's and heart problems.
According to Dr Kyriazis, running for a bus or having to work to meet a deadline are examples of “good stress”, that is situations with short-term or low stress. The stress usually makes us react quickly, and gives us a sense of achievement — we did it! However, in both situations, the stress damages the cells(细胞) in our body or brain and they start to break down. But then the cells own repair mechanism “switches on”and it produces proteins which repair the damaged cells and remove harmful chemicals that can gradually cause disease. In fact, the body's response is greater than is needed to repair the damage, so it actually makes the cells stronger than they were before.
“As the body gets older, this self-repair mechanism of the cells starts to slow down,” says Dr Kyriazis.“The best way to keep the process working efficiently is to ‘exercise’ it, in the same way you would exercise your muscles to keep them strong. This means having a certain amount of stress in our lives.”Other stressful activities that Kyriazis suggests as being good stress include redecorating a room in your house over the weekend, packing your suitcase in a hurry to reach the airport on time, or shopping for a dinner party during your lunch break.
So next time your boss tells you that she wants to see the report finished and on her desk in 45 minutes, don't worry; just think of it as “good stress” which will  benefit your long-term health!
