Peterson followed the health of his students the following year and discovered that the pessimists had twice as many diseases and made twice as many trips to the doctor as the optimists.
Later, Martin Seligman of the University of Pennsylvania and two of his colleagues, using interviews and blood tests, found that optimists have better immune (免疫的) activity than pessimists. Why? One big factor is that "Pessimistic individuals," as Seligman writes, "get depressed more easily and more often."
When a person is depressed, certain brain hormones (荷尔蒙) become reduced, creating a chain of biochemical (生物化学的) events that end up slowing down the activity of the immune system.
Optimists also look at information in more depth to find out what they can do about the risk factors. In a study by Lisa Aspinwall, at the University of Maryland, subjects read health-related information on cancer and other topics. She discovered that optimists spent more time than pessimists reading the severe risk material and they recommend more of it.
"These are people," says Aspinwall, "who aren't sitting around wishing things were different. They believe in a better outcome, and that whatever measures they take will help them to heal." In other words, instead of having their heads in the clouds, optimistic people look and seek. They aren't afraid to look into the situation because they're optimistic. Thus, for yet another reason, optimists are likely to be healthier.
The best news is what research has shown repeatedly: Anyone can become more optimistic with effort. And every effort you make to keep an optimistic attitude will reward you with a stronger immune system. So you'll enjoy better health.
