The study is based on an experience in Seattle, when public schools made radical reforms in primary, middle and high schools. Researchers at the University of Washington examined the sleep of teenagers suffering from chronic sleep deprivation when the study was delayed from 7:50 to 8:45.
Researchers reported that students who participated in the study improved their marks by 4.5% and slightly improved average attendance rates.
The study addressed the health benefits and studies that students can get if the time spent at school is delayed, but they warn that certain factors, such as phones and computers, may hinder advantages.
The researchers found that when teenagers slept longer with an additional 34 minutes, the total number of hours averaged from 6 hours to 50 minutes increased to 7 hours and 24 minutes.
In previous studies, many researchers recommend that teenagers sleep between 8 and 10 hours each night, which is difficult, especially with electronic devices that hinder their sleep.
Scientists compared their sleep patterns in 2016 when the weather was changed at 8:45 and those of 2017 at the end of the school day after their return at 7:50. They also found that the internal clock of teenagers worked better when they were allowed to sleep longer and that I disagreed
"Research has shown up to now that the daily rhythms of teenagers differ considerably from those of adults and children," said lead author Gidon Donster. "All studies on the sleep patterns of adolescents in the United States show that biologically determined, but the time of their awakening is socially determined."
"This has serious health and comfort implications, as the intermittent daily rhythm can negatively affect digestion, heart rate, body temperature, immune system function, attention capacity, and mental health. "
