钱挣得越多,压力就越小吗?

They say money can't make you happy, but scientists find that it can make your life a lot less stressful. A study of almost 200 adults making various amounts of money finds that the less money you make, the more stress your body feels. People at the lower end of the socioeconomic spectrum¹ had stress hormone² levels in their bodies that were 3 times higher than those who were better-off. The salary to stress link they found was independent of race, ages, sex or even weight. So money alone may have more impact than previously³ thought. The scientists say that being poor is often associated with less healthy lifestyles. The poor tend to smoke more and skip breakfast, two factors which have major stress effects on the body. Lower Economic classes also tend to have less education and resources for dealing⁴ with crises when they arise, which can put undue⁵ strain on the system. As for happiness, well, previous studies have shown that it's not how much money you have but how you think about it.
