What are the risks of electronic screens on the sleep of children and adolescents? | health | Essential information for better health | DW

He saidresearchersDene in reviewmethodologyfor studiesprecedent,The use of electronic devices by children and adolescents with screens, generally leads to a lack of sleep, and in many cases leads to a lack of sleep.

The four researchers from the Danish National Institute of Public Health at the University of Southern Denmark in Copenhagen used 49 studies conducted between 2009 and 2019 in their review, which was published in the journal BMC Public Health.

The number of children and adolescents in the studies, up to 15 years old, ranged from 55 to almost 370 000. A German-based psychologist says the review’s findings highlight the importance of keeping electronic media devices out of children’s bedrooms.

The researchers wrote in the review that sleep has a significant impact on the health and safety of children and adolescents. They note that it is essential for their development and ability to learn, and that prolonged insufficient sleep can have long-term health effects.

In addition to physical and psychological changes during childhood and adolescence, external factors can cause a lack of sleep, or an increase in its intensity, according to the researchers. Previous studies have shown that the use of cell phones, tablets and other devices with screens is one of those factors.

The researchers say the evidence for a link between electronic media use and shorter sleep is stronger among children aged 6 to 15 years, compared to children aged 5 years and younger. As for preschoolers, watching TV and tablets has been associated with difficulty falling asleep and getting less sleep.

Older children used a wider range of electronic devices, including video game consoles, cell phones, and computers. As for children between the ages of 6 and 12 years, electronic media use has been associated with delayed sleep times and sleep without depth.

For children between the ages of 13 and 15, their use of electronic devices with screens has been associated with sleep problems, and the use of social media has been associated with poor sleep.
The researchers also found that television and cell phone use at bedtime is associated with disrupted sleep-wake periods during the night.

Other ways in which electronic media use can interfere with the sleep response and cause sleep problems include “psychological stimulation of media content,” the researchers wrote. For children aged 13 to 15, they say their review supports evidence that interactive images from electronic media devices – as opposed to a television set – increase “physiological arousal” that can affect sleep.

Tanya Bolin, a psychiatrist at the Leipzig Research Center in Germany, says the Danish review collects findings on the topic of children’s use of electronic media and how they sleep. And this confirms the existence of a link between the electronic devices in their bedrooms and their abnormal sleep, which particularly emphasizes the role of cell phones.

She explains: “Some of the studies used also show an explicit link between night use of cell phones and poor sleep, which reaffirms (previous findings) that especially these devices, which can be placed anywhere and are not turned off during the night. sleep deprivation. “

Pauline says it is important for parents to be aware of the risks of electronic media devices. “They should establish clear rules from the beginning about when such media can be used,” she advises, adding that cellphones, tablets or other electronic devices should in no case be left in a children’s bedroom at night.

It also recommends that children do not use devices, including video game consoles and computers, just before bedtime, but preferably in the afternoon.
