No doubt, Sleep plays a vital role in good health and well-being throughout your life. Getting good sleep is one of the best things you can do for your health as it is important for learning and memory. Lack of sleep impacts our health and makes our body tired.
A new US research has revealed that teenagers are sleeping fewer hours per night than generations before them. One relevant reason? Teens are trading their sleep for smartphone time. By 2015, 43 percent of teens reported sleeping less than seven hours a night – which means almost half of U.S. teens are significantly sleep-deprived.
What is the reason behind sleep deprivation among teens to such unprecedented levels?
The research comes from Jean M. Twenge, a professor of psychology at San Diego State University, and collaborators from Iowa State University. Twenge and her team looked at the data from two nationally representative surveys done between 2009 and 2015.
One survey asked students in the 8th, 10th and 12th grades how often they got at least 7 hours of sleep, while the other asked 9th-12th-grade students how much sleep they got on an average school night.
After analyzing the data, the researchers found that in 2015, about 40 percent of teens were sleeping less than 7 hours most nights which is 58% more than in 1991 and 17% more than in 2009. According to their findings, those who spent 5 hours online daily were 50 percent more likely to get less sleep compared to those who only spent an hour online each day.
For many people, smartphones, tablets, laptops are an indispensable part of everyday life, Twenge stresses.
Limiting their usage to 2 hours a day should leave enough time for proper sleep, she says. And that’s important advice for young and old alike.
“Given the importance of sleep for health, both teens and adults should consider whether their smartphones use is interfering with their sleep,” she says. “It’s important not to use screen devices right before bed, as they might interfere with falling asleep.”
The findings can be found published online in the journal Sleep Medicine.
Why sleep is important?
Too little sleep can lead to weight gain and lack of sleep is associated with higher incidence of behavioral problems, especially attention deficit and hyperactivity disorder (ADHD).
Without proper sleep you will probably be tired and irritable. You may feel “wired” because the body produces extra Adrenalin, or you may feel slowed down because of fatigue. There are many-many side effects of insufficient sleep.
According to sleep experts adults need 9 hours of sleep each night to be productive and perform their best at school. Less than 7 hours of sleep is insufficient. That is why a good night’s sleep is incredibly important for health.
