A new study has found that social media could be affecting the sleep of young adults.
The study is a project of researchers at the University of Pittsburgh's School of Medicine. They found that young people who often use social media are more likely to suffer from sleep disorders than those who use social media less. The researchers say doctors should ask young adults about their use of social media when treating sleep issues.
"This is one of the first pieces of evidence that social media use really can influence your sleep." said Jessica C Levenson. She was the lead author of a report on the study.
The researchers set out to examine the connection between social media use and sleep among young adults. Levenson noted that these young adults are possibly the first "generation to grow up with social media."
The researchers wanted to find out how often young people used social media sites like Facebook, Twitter, Credit and Tumbler. For the study, they gave questionnaires to nearly 1,800 adults, aged 19 to 32. On average, members of the study group used social media sites one hour a day. They also "visited various social media 30 times per week."
Thirty percent of the study's participants reported having serious problems with sleeping. Those people who used social media a lot were three times more likely to have a sleep disorder. And those who spent the most time on social media were two times as likely to suffer from sleep disturbances.
Levenson said the number of times a person visits social media is a better predictor of sleep problems than overall time spent on social media. If this is true, she adds, then practices that stop such behaviors may be the most effective.
Tiger research: Indonesia While sustainable tourism helps protect many of the Indonesia's wildlife, one of its rarest species, the Sumatran tiger, suffers as the island's cities expand into its forest habitat. Fortunately Biosphere Expeditions have created a trip that not only benefits the seriously endangered animal, but helps protect it too. Based in a remote camp in the heart of the rainforest, volunteers will be needed to tour the landscape, documenting tracks, kills and scats(粪便) to aid important research into the lives of these big cats.

Teaching: Morocco It's the breathtaking beauty that draws tourists to Morocco's High Atlas Mountains, but while the remoteness of the setting may aid its charm it also causes problems. Few inhabitants of the region's rural villages, especially females, continue their education past primary school. Education For All (EFA) is a Moroccan NGO that builds and runs girls' boarding houses near secondary schools in the High Atlas, making further education theoretically possible. Based in the beautiful town of Asni, the programme is looking for female volunteers with teaching experience.
