Teens of this generation are generally getting less sleep than those of previous generations. What could be the reasoning behind this trend?
According to a study performed at Uni Research Health in Norway, the culprit could be the hours a day teens spend using electronic devices. The study was based on data gathered from 10,000 16- to 19-year-old boys and girls, who were asked about their daily quantity of screen time as well as their sleeping habits.
The findings were that those who used an electronic device for over four hours a day had a 49% higher risk of taking longer than an hour to fall asleep. Those who exceeded two hours of screen viewing per day were more likely to toss and turn before falling into a deep sleep. Teens who used multiple devices throughout the day were more likely to get less than five hours of sleep per night.
The reasoning behind this might be linked to the screen light, which may impact sleep hormone production. It could also be related to the social communication aspect, such as anticipating a response from a friend.
An easy way to fix this problem would be to treat electronic devices like any other stimulant (such as caffeine) and limit their use before bedtime and just in general. If the devices are not used while in bed, the body and mind won’t associate the bedroom with wakefulness, and could thus obtain better sleep.
