FRIDAY, Oct. 20, 2017 (HealthDay News) — Teens sleep less than they used to, sacrificing shuteye to spend more time on their phones in addition to tablets.
Experts say teens need at least nine hours of sleep a night to be engaged in addition to productive during the day. Anything less can cause daytime sleepiness in addition to interfere with school or daily activities.
Faced with an array of tempting distractions, how much sleep are today’s teens actually getting? To find out, researchers analyzed a pair of long-term, national surveys of more than 360,000 eighth- through 12th-graders.
One survey asked eighth-, 10th- in addition to 12th-graders how often they got at least seven hours of shuteye. The different asked high school students how long they slept on a typical school night.
In 2015, 4 out of 10 teens slept less than seven hours a night. which’s up 58 percent since 1991 in addition to 17 percent more than in 2009 when smartphone use became more mainstream, the researchers said.
“Teens’ sleep began to shorten just as the majority began using smartphones. This particular’s a very suspicious pattern,” said study leader Jean Twenge, a psychology professor at San Diego State University.
The more time students reported spending online, the less sleep they got, according to the study published Oct. 19 from the journal Sleep Medicine.
Those who were online a few hours a day were 50 percent more likely to be sleep-deprived than classmates who limited their daily time online to an hour.
Studies have shown which light by smartphones in addition to tablets can disrupt the body’s natural sleep-wake cycle.
“Our body is actually going to try to meet its sleep needs, which means sleep is actually going to interfere or shove its nose in different spheres of our lives,” said study co-author Zlatan Krizan, an associate professor of psychology at Iowa State University. “Teens may catch up with naps on the weekend or they may start falling asleep at school.”
Though smartphones, tablets in addition to different electronic devices are often an essential part of life, the researchers said moderation is actually key. Everyone — young in addition to old alike — should limit use to two hours each day, they advised in a San Diego State University news Discharge.
“Given the importance of sleep for both physical in addition to mental health, both teens in addition to adults should consider whether their smartphone use is actually interfering with their sleep,” Twenge said. “This particular’s particularly important not to use screen devices right before bed, as they might interfere with falling asleep.”
