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.

Six Chinese survived the tragedy of the Royal Mail Ship Titanic, but disappeared soon after. Now a British documentarian, Arthur Jones, will uncover stories and histories of discrimination.
There were eight Chinese between the ages of 24 and 37 on the Titanic, sharing one 59-pound third-class ticket, but only six survived from its sinking. When they arrived in the United States, they were not helped like the other 705 survivors. Instead they were forced to leave the country within 24 hours because of the Chinese Exclusion Act signed in 1882.
Some westerners questioned the six Chinese survivors as stowaways and claimed that they survived because they secretly climbed on the lifeboat or dressed as women to board lifeboats.
But after visiting foreign documents, museums and cooperating with American and Chinese historians, Jones believes they did not do anything disgraceful in order to survive the disaster. ''This is not only a story about the survivors of Titanic, but also a story of a group of brave Chinese people exploring the outside world at that time, '' he said.
When the ship hit an iceberg, like other third-class passengers the eight Chinese were released from the locked gates at last, but not allowed to board the lifeboat. Luckily, four of them boarded a small broken boat, and one was rescued by another lifeboat. Another one, Fang Lang, floated on a piece of wooden board in the sea. The only returning lifeboat saved him from freezing.
To restore their real stories, Jones and his team found Fang Lang's son in Wisconsin, US. Also, Jones will visit Taishan city in south China's Guangdong province, recorded as the survivors' hometown. The filmmakers also established a website, whoarethesix.com, for more clues.
Ordinarily, people think of Titanic as a story of rich white people, but don't know there were people from all over the world, including Chinese. ''Their stories are never told, '' Jones said.
The documentary The Six is expected to be released in China late this year.
