Optimism (乐观) doesn't mean paying no attention to things that cause stress. But when bad things happen, optimistic people are less likely to be unhappy about themselves and more likely to see the bad things as something that lasts a short time.
A new research has found a direct connection between optimism and healthier diet and exercise behaviors, as well as better heart health, a stronger immune system (免疫系统), better lung function, and lower death risk. "Optimistic people, regardless of sex, often have goals and the confidence to reach them," Lee said. "Those goals could include healthy habits that contribute to a longer life."
Studies find only about 25% of our optimism is controlled by our genes (基因), and the rest is up to us. It turns out we can actually train our brain to be more positive. Researchers studied the brains of monks (僧侣) and found surprising results: Tens of thousands of hours of meditation(冥思) had changed the function (机能) of their brains, which support positive qualities. And that may be key in producing the effect on the body.
There are simple mental exercises to develop an optimistic attitude. One of the most effective ways to increase optimism is called the "Best Possible Self" method. That is to imagine ourselves in a future in which we have achieved all our life goals. And keeping a diary in which we list the positive experiences we had can also help shape our attitude. Taking a few minutes each day to write down what makes us thankful can improve our view on life, too.
