Sleep problems suffered by teenagers can be improved after just one week by limiting evening exposure to light-emitting screens on mobile phones, tablets and computers, a study suggests. The research indicates that by reducing their exposure to blue light-emitting devices in the evening, adolescents can improve their sleep quality and reduce symptoms of fatigue, lack of concentration and mood swings after seven days. The new research from the Netherlands found that teenagers who had more than four hours per day of screen time had sleep-onset and wake-up times on average 30 minutes later than those who recorded less than one hour per day of screen time, as well as more symptoms of sleep loss. The team conducted a trial to assess the effects of blocking blue light with glasses and no screen time during the evening on the sleep pattern of 25 frequent users.

Teenagers in Britain may be putting their health and education at risk by spending too much time on social media at bedtime, according to a major study into adolescent sleep habits. More than a third of teenagers spent at least three hours a day on social media, with a fifth devoting at least five hours to the activity, researchers found. Those who were on social media for three hours or more daily were most likely to get to sleep late. Insufficient sleep in adolescence has been linked to a range of mental health problems, obesity and poor performance at school. Scientists at the University of Glasgow released the findings in a preliminary report that has yet to be peer reviewed and published in a journal.

Emily Vaughn. Today's teens have a lot on their plate. They strive for perfect grades, college-essay worthy volunteer gigs, trophies in multiple sports — and many of them still find hours a day to spend on social media. And it may be they're trying to make for up it online.
Teenagers using social media for more than three hours a day are more likely to go to bed after and wake during the night, UK research suggests. This affects one in three teens - with one in five spending five hours or more on apps like Instagram, WhatsApp and Facebook every day, the study said. The University of Glasgow researchers said 13 to 15 year-olds may be delaying bedtime by being on their phones.
