Past studies have shown that people who are married or in a long-term relationship tend to be healthier than those who are single and new research suggests that they are also better at dealing with stress. Researchers from Chicago University studied 500 students, about half of whome were married or in a long-term relationship. The students were asked to play an economic computer game which they thought could affect their course marks and chances of getting a good work placement later. After the tests the researchers measured the levels of the stress hormone cortisol in the participants' saliva and found that the students who were married or had a partner produced much less of it.
