　　运动有助于减少焦虑情绪

　　The Daily Mail: Regular exercise may help those who see their environments as threatening to feel less anxious.

　　Working out can make people feel more positive about our environment, thus helping¹ us worry less about ambiguous situations.

　　Researchers looking into the correlation² between perception of threat and exercise made the conclusion after conducting a study.

　　They got 66 students to either stand still, walk or jog on a treadmill³, and then watch an animation⁴ of a humanlike stick figure. The figure's orientation⁵ was ambiguous, and could be perceived as walking away or toward the viewer.

　　Overall, the students in the study who walked or jogged were more likely to say the figure was walking away from them - that is, was less threatening - than the students who stood still on the treadmill.

　　The researchers said his findings suggest that exercise could reduce anxiety by fostering the perception of a more positive environment.
