According to a new review of research about good moods (心情) and physical activity, people who work out even once a week or for as little as 10 minutes a day tend to be more cheerful than those who never exercise. And any type of exercise may be helpful.
The idea that moving can affect our moods is not new. A number of past studies have noted that physically active people have much lower risks of developing anxiety than people who rarely move. But that research centered on the relationship between exercise and mental problems. Fewer past studies explored links between physical activity and positive emotions, especially in people who already were mentally healthy, and those studies often looked at a single age group or type of exercise.
So for the new review, researchers at the University of Michigan decided to collect and analyze various past studies of working out and happiness. They began by combing research databases for relevant studies. Most of those were observational, meaning that the scientists simply looked at a group of people, asking them how much they worked out and how happy they were. A few of the studies were experiments in which people started exercising and researchers measured their happiness before and after. The number of participants (参与者) in any one study was often small, but together, they represented more than 500,000 people ranging in age from teenagers to the old.
For most of them, the Michigan researchers found, exercise was strongly linked to happiness. Every one of the observational studies showed a beneficial relationship between being physically active and being happy. The type of exercise did not seem to matter. And the amount of exercise needed to influence happiness was slight (微小的). In several studies, people who worked out only once or twice a week said they felt much happier than those who never exercised. In other studies, 10 minutes a day of physical activity was linked with cheerful moods.
