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. Blocking blue light with glasses and screen abstinence resulted in sleep-onset and wake-up times occurring 20 minutes earlier and a reduction in reported symptoms of sleep loss in participants after a week.

The first thing to understand is that teenagers are still growing and their brains are still developing — so they need more sleep than adults. They also have different sleep-wake rhythms and release melatonin a natural hormone to prepare for sleep later, which means evening sleepiness takes longer to occur and they have a tendency to go to bed later and to sleep later in the morning.
Sleepy Teens – new study says teens are even more sleep-deprived than we thought

After public schools in Seattle reorganized school start times, teens got more sleep on school nights—a median increase of 34 minutes of sleep each night. This boosted the total amount of sleep on school nights from a median of six hours and 50 minutes, under the earlier start time, to seven hours and 24 minutes under the later start time, according to a new paper in Science Advances.
