Bedroom devices are associated with children losing sleep time and quality, new research says

Even kids and teens who don’t stay up late online are losing sleep


Nowadays, teachers often face classrooms full of yawning students.

New studies show that for children and teens, using mobile phones, tablets, and computers at night reduces sleep time and quality. Even children who don’t use cell phones or other technologies cluttering their bedrooms at night are more likely to close their eyes and fall into daytime sleepiness. Analysis published today at JAMA Pediatrics find.

As a result of the analysis, “a consistent pattern of effects in various countries and environments” was found. Ben Carter, Lead Author and Senior Lecturer of Biostatistics at King’s College London.

Carter and his colleagues examined the medical literature to identify hundreds of relevant studies conducted between January 1, 2011 and June 15, 2015. 14 and a half years. After extracting the relevant data, Carter and his co-authors performed their own meta-analysis.

Few parents are surprised by this result. The team found a “strong and consistent link” between bedtime media device use and inadequate sleep volume, poor sleep quality, and excessive daytime sleepiness.

But to my surprise, Carter and his team discovered that children who didn’t use the device in the bedroom were still interrupting their sleep and could suffer from the same problem. The light and sound emitted by technology, and the content itself, can be too exciting.

Carter admits that the weakness of the analysis was “how the data were collected in the primary study: self-reporting by parents and children”, but many of us probably reflected in our statistics. You will recognize family habits.

Large-scale poll conducted in the United States National Sleep Foundation (PDF) reported in 2013 that 72% of all children and 89% of teens have at least one device in their sleeping environment. Most of this technology was used before bedtime and the same report was found.

According to Carter and his co-authors, this ubiquitous technology negatively impacts children’s sleep by delaying their sleep when they watch movies or play another game. ..

Researchers explain that the light emitted by these devices can also affect the biological processes of internal clock timing such as circadian rhythms, body temperature and hormone release. One particular hormone, melatonin, induces fatigue and contributes to the timing of the sleep and wake cycle. Electronic lights delay the release of melatonin, disrupting this cycle and making it harder to fall asleep.

Carter and his co-authors also find that online content is psychologically stimulating and can keep awake far beyond the time children and teens try to turn off their devices and sleep. It suggests that.

“Sleep is essential for children,” he said. Sujay Kansagra, director of the Child Neurology and Sleep Medicine Program at Duke University Medical Center, was not involved in the new analysis. “We know that sleep plays an important role in brain development, memory, self-regulation, attention, immune function, cardiovascular health, and more.”

Kansagra, “My child never sleepsNote that the period of maximum brain development is the first three years of our lives, which corresponds to when we need and get the most sleep. “It’s hard to believe this is a coincidence.”

Kansagra said parents may have underreported children using the device at night, but technology is probably simply a hindrance to sleep hygiene. “For example, a child who is allowed to keep the device in the room is more likely to avoid good sleep routines that have been found to help sleep,” he said.

“We don’t know all of the science behind it, but we agree that sleep plays an essential role in the healthy development of children,” said Neil Klein, president of the American Society of Sleep Research. There are even some studies demonstrating the association between ADHD and some sleep disorders. ”

In many respects, the results of the new research are not surprising. “Sleep hygiene has been heavily influenced by technology, especially for a decade,” he said, based not only on research, but also on his own “personal experience and anecdotes of many other sleep professionals.” Klein said.

    Another important tip National Sleep FoundationWe recommend a “gadget-free transition time” of at least 30 minutes before bedtime. Turn off the power for a better sleep.

    Other recommendations for good sleep hygiene include not exercising (physically or mentally) too close to bedtime. Establish a regular sleep schedule. Limit exposure to light before sleep. Avoid stimulants such as alcohol, caffeine, and nicotine for a few hours before bedtime. Create a dark, comfortable and peaceful sleeping environment.
