Facebook lets friends connect. They can give each other updates, share photos and post comments. But that’s not all. Facebook might also stress users out.
In a new study, 88 volunteers how much time they spent on Facebook and the types of Facebook posts and comments that they made. In addition, they answered questions about their feelings and state of mind. They also offered saliva. Researchers tested it for cortisol. This chemical is a stress hormone. Levels of it vary throughout the day.
In this study, people with the most Facebook friends, more than 300, had somewhat higher cortisol levels. Additionally, the more Facebook friends that users had, the more likely they were to feel anxious. On the other hand, youths who gave lots of ''likes'' and supportive comments on Facebook had lower cortisol levels. ''The more social support you give to others, the lower your stress hormone levels will be, '' says Lupien.
''This research decidedly combines the social science approach and the medical science approach on an important question in our social-media age, '' says Wenhong Chen, a sociologist at the University of Texas at Austin. ''It's ready pleasantly new to see Lupien’s team study cortisol levels-along with questionnaire data. ''
One finding from Lupien's work surprised Chen. Teens who felt they got a lot of support from others also had higher cortisol levels. Usually, she says, those feelings should protect people from stress. ''There are many potential dangers of social media use among young people, '' Chen notes. So, she says, enjoy Facebook, but be aware of the risks.
Lupien suggests that teen Facebook users share information with and support their friends on the site. They shouldn’t just stay silent. ''if anyone is more stressed, it's the watchers, not the sharers, '' she says. Also, she recommends that people who use social media heavily should find time to take active walks, to run or to do other activities. Cortisol increases a person's energy. “The best way to reduce stress hormones is to use the energy, '' she says.

They are the sort of friends who are so close that they trust each other with their lives. If one falls, the other is there to catch him.
They are Wellman, whose legs were permanently injured nine years ago in a rock-climbing accident, and Corbett, an experienced rock climber. Together, they climbed up Half Dome, the famous 2, 000-foot rock in the Yosemite National Park, through one of the most difficult routes(路线).
During the climb, Corbett took the lead, hit in the metal spikes(尖状物)that guided the ropes, and climbed up. Then, after Wellman pulled himself up the rope, Corbett went down to remove the spikes and climbed up again. This process was repeated time and again, inch by inch, for 13 days. Wellman’s job was not easy either. He got himself up the rope through upper body strength alone. In all, Wellman figured that he had done 5, 000 pull-ups up the rope on the climb.
However, when the two men first met, they never talked about climbing. “He knew that was how I got injured. ”Wellman said. Until one day Wellman decided that he wanted to climb again and they started training.
Their climb of Half Dome was not all smooth. At one point, pieces of rock gave way, and Corbett dropped down quickly. Wellman locked their rope in place, stopping the fall at 20 feet. His quick action probably saved his friend’s life.
“Your partner can save your life—you can save your partner’s life. ”Wellman said as the pair received congratulations from friends. “There are real close ties. ”

2. Why did the two men never talk about climbing when they first met?
A. Corbett was poorly trained.
B. Wellman had lost interest in climbing.
C. Corbett didn’t want to hurt Wellman.
