Wrisks of electronic screens on children sleep

He said researchers Danes in review methodology for studies precedent, 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 nearly 370,000. A German-based psychologist says the review’s findings underscore 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 vital to 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 youth, external factors may cause a lack of sleep, or an increase in its intensity, according to the researchers. Previous studies have shown that the use of mobile phones, tablet computers, and other devices with screens is among 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, compared to children aged 5 and younger. As for preschool children, watching TV and using tablet computers was associated with difficulty falling asleep and sleeping less.

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 was 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 was associated with sleep problems, and the use of social media was associated with poor sleep.
The researchers also found that television and mobile phone use at bedtime was associated with disrupted sleep-wake periods during the night.

Other ways in which electronic media use may interfere with the sleep response and may cause sleep problems include “psychological stimulation from media content,” the researchers wrote. For children aged 13 to 15, they say their review supports evidence that interactive images of 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 that the Danish review collects findings on the topic of children’s use of electronic media and how they sleep. And it confirms the existence of a link between the electronic devices in their bedrooms, and their abnormal sleep, stressing the role of mobile phones, in particular.

She explains: “Some of the studies that were used also show an explicit association between nighttime use of mobile phones and poor sleep, which reaffirms (previous findings) that these devices in particular, which can be placed anywhere and are not turned off during the night It could spoil sleep.”

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

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

      To create your own children’s playgrounds

      The idea: “to build children’s playgrounds yourself” that flourished in the 1960s led to the emergence of a new form of educational activities. Based on this idea, parents worked to form a team tasked with creating special playgrounds for their children in urban areas. They owned many ruins, and used Raw materials are available to create places for their children to play.

      The first children’s playground was built in New York City in 1890, and the playground was very simple and was surrounded by a large fence. The attached photo is of a section of Central Park, taken in 1972. Over the decades, playground designs have become more complex, and bridges have incorporated concrete columns into the process of creating children’s playgrounds.

      Danish architect Carl Theodor Sorensen had many theories regarding best practices for children’s playground design. Sorensen was the first to adopt in 1931 the concept of stadiums designed to integrate urban sites with natural spaces. Sorensen gave the children building materials and equipment and left them alone to build the playground the way they liked. Architect Sorensen led a campaign to encourage the creation of green spaces in order to stimulate creativity in children.

      Figures for children’s play

      In the past, various available building materials were used in the construction of children’s playgrounds: steel, ropes, wood, and reinforced concrete were used. In the sixties of the last century, new building materials entered, which led to the emergence of new and innovative design ideas and methods in the process of creating children’s playgrounds, such as this model participating in the exhibition.

      With the increasing popularity of children’s playgrounds, the playgrounds became large and in line with the impact of life as well. Figurines were not only distinguished by their shapes, but also became popular with children. Recently, there has been a growing concern among parents about safety measures in children’s playgrounds, and this has led to tightening restrictions on the degree of safety and the suitability of these playgrounds for children’s play.

      In the early 1930s, designers of children’s playgrounds attempted to integrate natural elements with children’s play spaces in their urban environments in order to provide the advantages enjoyed by their peers in rural areas. In order to achieve this goal, beach sand was brought into urban playgrounds and grassy areas were transformed into thick forests.

      The Dutch architect Aldo van Eyck is one of the most famous architects who adopted the idea: “We cannot separate our children from play,” and that children’s play should occupy an important part of city life and should not be separated from it. Van Eyck worked for the city of Amsterdam’s urban planning department. Van Eyck’s designs are characterized as working to close relationships between people.

    “We want to make the museum and the galleries more lively,” said Gabriela Burkhalter, curator of the Children’s Playground Project in Bonn. The project began with extensive research in 2006 and worked on a review of the construction and development stages of stadiums in the last century.
