Technology in a child's bedroom is associated with less sleep each night

A child sleeping with technology in his or her bedroom has been shown to be associated with up to one hour less of sleep per night.

Sleep, or lack thereof, and technology often go hand in hand when it comes to school-aged kids. Nearly three out of four children (72%) between the ages of 6 and 17 have at least one electronic device in their bedrooms while sleeping, according to a National Sleep Foundation survey. Children who leave those electronic devices on at night sleep less -- up to one hour less on average per night, according to a poll released by the foundation earlier this year.

Dr. Jill Creighton, Assistant Professor of Pediatrics, Stony Brook Children's Hospital says the key to a successful school year starts with Z's. So parents, how can you power down your kids at night and make bedtime easier? Dr. Creighton shares her tips. "First -- develop a nighttime routine," says Dr. Creighton. Whether it's a bath, reading a book or listening to soothing music, these actives will have a better impact on your child to help them relax before going to sleep.

Second -- Power off! "The hour before bed should be a no-electronics zone," says Dr. Creighton. Studies show that the light from backlit electronics (like tablets, smartphones and video games) can disrupt our ability to fall -- and stay -- asleep. Dr. Creighton says designate a spot in your home for electronics to be plugged in, then have your kids start their bedtime routine by plugging in one hour before lights out. Ban hand-held devices from the bedroom. "The burst of light from a phone (even if it's just to check the time) can break a sleep cycle," says Dr. Creighton. "A regular alarm clock is best."

If your child has a slight addiction to technology and is resistant about turning off their device, try dialing down the screen time. "Reduce screen time by 30 minutes or more each week until you reach your goal," says Dr. Creighton. "A good rule of thumb is try to limit recreational screen time to 60 minutes every day. And for every 30 minutes of screen time, make sure your kids get 30 minutes of physical activity."

Try to replace screen time with an activity. "It's sometimes hard to get kids off the couch and get them moving, especially if they think of physical activity as "exercise'' or "boring," says Dr. Creighton. "Parents, get creative and make moving fun for kids." Some of Dr. Creighton's ideas: a 20-minute family walk, 20 minutes of shooting hoops outside, walking the dog, going bike riding and doing chores (with the promise of an allowance) such as vacuuming, putting away laundry, raking leaves, shoveling snow and helping with the garbage/recycling, which are big favorites in her household.

Lastly, establish good habits. Being distracted by phones, hand-held devices and TV shows during mealtime cannot only lead to overeating, but additional unneeded screen time. And be a good role model. Parents, set a good example when it comes to screen time.

So how much sleep do your children need? General sleep guidelines from the National Heart, Lung and Blood Institute show that sleep time change as we age, but experts say there is no magic number for sleep, with individual needs varying.

• Newborns: 16-18 hours a day.

• Preschool-age children: 11-12 hours a day.

• School-age children: at least 10 hours a day.

• Teens: 9-10 hours a day.

• Adults (including the elderly): 7-8 hours a day.

Not getting enough sleep adds to health problems in teens

A study shows that teenagers increase their risk of developing health issues due to  getting too little sleep (6 hours or less). Electronics in the bedroom are blamed for getting too little sleep.

Many teens from lower- and middle-income homes get too little sleep, potentially adding to the problems of kids already at risk for health issues, new research finds.

The study of 250 high school students found they slept an average of six hours a night, far less than the recommended amount -- about nine hours.

Kids who skimp on sleep are more likely to report feeling hopeless, as well as smoke, drink alcohol and use marijuana, according to background information in the report, published online April 21 in Pediatrics.

"Many teenagers, especially blacks, do not get enough sleep, which may contribute to their risk for poor health," said lead researcher Karen Matthews, a professor of psychiatry at the University of Pittsburgh School of Medicine.

"Inadequate sleep can result in academic underachievement, health-damaging behaviors and negative mood," she said.

Matthews said sleep deprivation isn't confined to the poor. "Many kids who come from upper class families also do not get enough sleep, but our study focused on poorer children because of a lack of data available in those [upper class] students," she said.

The researchers wondered if the challenges of living in disadvantaged circumstances would affect sleep patterns. In their sample, 60 percent of the kids lived in single-family homes. Overall, the kids were heavier than national average, the researchers said.

Matthews isn't sure why these teens aren't sleeping enough. "However, factors that determine bedtime play a key role for sleep duration because of mandatory school start times," she said.

"Bedtimes can be quite late if students are using electronic devices late into the evening, and bright light exposure [from these devices] can keep them up," she said.

Late-night studying was not a factor in this sample, Matthews said.

Dr. Metee Comkornruecha, an adolescent medicine specialist at Miami Children's Hospital, said the study shows "what a lot of us are thinking -- that adolescents aren't getting enough sleep."

Kids are prone to a lot of distractions, he said. "Cell phones are used not only for texting but to look on the Internet and for various types of social media. That frequent stimulation can keep these kids up."

Comkornruecha recommended removing electronic distractions from the bedroom. "Take the phones, computer and TVs away from the bedroom. If they're there, kids are going to use them. But if the bedroom is a safe haven for sleeping, then that's what it is going to be used for," he said.

Among the students whose sleep patterns were monitored, 57 percent were black and 54 percent were girls. All came from low- to middle-class families.

Matthews said besides looking at kids from poorer families, they wanted to look at any differences by race because two studies of middle-aged adults suggested that blacks had worse sleep than whites. "Thus, we conducted our study at an integrated high school that had black and white students of similar economic backgrounds," Matthews added.

The researchers had the students complete questionnaires and keep a diary of the length and quality of their sleep. At night, the teens were hooked up to an electronic device that monitored their sleep.

On school nights, the teens slept about six hours, and on the weekend, about seven hours. Matthews' team found that blacks and males slept less than other kids, and their sleep was more fragmented. Girls reported poorer quality of sleep and said they were often tired during the day.

The researchers previously reported that insufficient sleep is linked to higher blood pressure and insulin resistance, a risk factor for diabetes.

Autistic boys get less sleep with media in bedrooms

A study shows that media screens in the bedroom of autistic boys resulted in them getting significantly less sleep.

For boys with autism, having easy access to media in the bedroom is linked to significantly less sleep, according to researchers from the University of Missouri.

“Previous research has shown that bedroom access to screen-based media is associated with less time spent sleeping in the general population,” said Christopher Engelhardt, Ph.D., a postdoctoral research fellow at the MU Thompson Center for Autism and Developmental Disorders and the MU School of Health Professions.

“We found that this relationship is stronger among boys with autism.

“Our current results were cross-sectional, meaning that we are not able to determine whether pre-bedtime media exposure causes some children with autism to sleep less,” he said.

“However, the relationship between bedroom media access and sleep was particularly large among boys with autism, suggesting that we should continue to carefully research this possibility.”

For the study, researchers looked at the relationship between media use and sleep among boys with autism compared to typically developing boys or boys with attention-deficit/hyperactivity disorder (ADHD).

Parents of the boys in each group were surveyed regarding the child’s hours of media use each day, bedroom access to media and the average hours of sleep they received per night. The findings revealed a link between bedroom access to a television or computer and reduced sleep among boys with autism.

Furthermore, average video-game exposure was connected to less time spent sleeping among the boys with ASD.

“Even though our findings are preliminary, parents should be aware that media use may have an effect on sleep, especially for children with autism,” Engelhardt said. “If children are having sleep problems, parents might consider monitoring and possibly limiting their children’s media use, especially around bedtime.”

Engelhardt says future research should investigate the processes by which bedroom access to media could contribute to sleep disturbances in children with autism spectrum disorder (ASD).

“It is also important to note that some media use may also be beneficial for children with autism,” Engelhardt said. “Future research is also needed to determine how video games and other technologies may be helpful in teaching and reinforcing skills and behaviors.”

It is estimated that about one in 88 children have ASD, which is characterized by social and communication difficulties as well as repetitive behaviors.

Sleep problems are very common in children with autism, and this may be due to a variety of underlying causes. Media use may worsen some of these underlying factors, and it appears to be an area for future research, Engelhardt said.

Too much computer time makes autistic children sleep less

Autistic children are prone to sleep disorders, and excess screen time could add to the likelihood of sleep disorders in these children.

Kids with autism and related disorders are prone to sleep disturbances but a new study finds that screen time, especially in the bedroom, may make their sleep problems worse.

When researchers compared boys with autism spectrum disorders (ASD) to other boys, they found that all the kids with bedroom access to media slept fewer hours, but the relationship was twice as strong for the boys with autism.

"In-room media access was associated with about 1.5 fewer hours of sleep per night in the group with autism," said Christopher R. Engelhardt, who led the study at the University of Missouri-Columbia.

"This association can potentially be problematic, particularly if the reduction in sleep interferes with other daily activities, such as school, homework, interactions with other people, or driving," he told Reuters Health in an email.

Past studies suggest that up to 80% of kids with autism, and related conditions like Asperger's disease, experience sleep troubles, including difficulty falling asleep or staying asleep through the night.

Hormone melatonin

Children with attention deficit hyperactivity disorder (ADHD) also are known to have a high rate of sleep disturbances. With both conditions, it's unclear why sleep is so difficult.

Theories include a disruption in sleep-wake cycles that are regulated by the hormone melatonin, which is often deficient in kids with ASDs, Engelhardt and his colleagues write in Paediatrics.  Because kids with autism spectrum disorders, like those with ADHD, also tend to spend a lot of time watching TV and playing video or computer games, the researchers wondered whether that could be contributing to their sleep problems.

So they recruited the parents of 49 boys with autism spectrum disorders, 38 with ADHD and 41 comparison boys with typical development to fill out questionnaires about their children's bedroom screen access and sleep patterns.

 All the kids were between ages eight and 17. Boys with autism who had TV, computers or video games in their bedrooms got less sleep than all the other boys, including boys with autism who didn't have media in their bedrooms.

Limiting electronics

Without a TV in their room, boys with autism spent an average of about nine hours sleeping, compared to less than eight hours among kids with an ASD and a bedroom TV.

In contrast, bedroom TVs didn't seem to make a difference for boys with ADHD or typical development. Boys with autism with computers in their rooms slept nearly two hours less than boys with autism and no bedroom computer.

A lot of time spent playing video games, regardless of where they were located, was also linked to shorter sleep times among boys with ASDs. Even for typical children, too much time with TV or video games has been linked to attention problems, hyperactivity, arguments and physical fights, Engelhardt said. "We can't say that access to a TV causes less sleep," only that the two are linked for some kids, he said.

Last month, the American Academy of Paediatrics called for limiting screen time for all kids to one or two hours per day. ”This is a good recommendation for all children," Dr Beth Marlow, Burry Chair in Cognitive Childhood Development and director of the Sleep Disorders Division at Vanderbilt University Medical Centre in Nashville, Tennessee.

"Following this recommendation for kids with (autism spectrum) and ADHD is good, although children with (autism spectrum) or ADHD who are still having difficulty with sleep despite limiting electronics really deserve a sleep evaluation by their paediatrician or sleep specialist.

Time distortion

"Sleep troubles can also stem from anxiety, sleep apnoea, pain that the child might not be able to express, gastrointestinal problems or seizures, she said.

For typically developing kids, bedroom TV access doesn't usually seem to cut into sleep. "However, (Engelhardt's) finding for teens with ASD concurs with our clinical impressions – that these teens have difficulty 'switching off'' videogames," Michael Gradisar said.

Gradisar is a clinical psychologist who studies technology use and sleep, especially among teens, at Flinders University in Adelaide, South Australia. "Many teens have a distorted sense of time passing when playing videogames, however, it may be that this time distortion is stronger for teens with ASD," he said.

Parents can have a tough time managing how much their children play games or watch TV, he said. "It may take quite some time to do, but one option is for parents to introduce other hobbies and activities into their teens lives, so that video gaming eventually occupies less time."

Engaging features

"People with autism tend to spend more time with media outlets, researchers think, because the electronic worlds have engaging audio and visual features and their social interactions are easy relative to real life interactions."

This doesn't necessarily mean that parents should take TVs or video games out of their autistic children's rooms, but might consider limiting or monitoring media consumption, he said. "Screen media can certainly be good for kids with autism," he said.

"Scientists have long known that video games are great at teaching and reinforcing certain behaviours, so it's possible that these games can be used to adjust and shape the types of behaviours generally valued by society, such as behaviours intended to help others."

Why technology doesn't belong in a child's bedroom

This article discusses why technology in a child's bedroom is detrimental to their sleep quality.

Technology such as computers and smartphones in children's bedrooms can cause anxiety and sleep loss, scientists at Canada's Dalhousie University report.

Having technology such as televisions, smartphones and game consoles in the bedroom teaches the brain to see the room as an entertainment experience rather than a place for quiet and rest, they said.

Playing violent video games in the bedroom conditions the brain to see it as a place of danger, leading it to stay in a state of alert rather than resting, they added.

"One of the biggest culprits for inadequate and disturbed sleep is technology," Dalhousie researcher Jennifer Vriend, the study's lead author, said.

"Many teenagers sleep with their phones and they are awakened regularly by it ringing or vibrating throughout the night when they get a text, email or Facebook message.

"Having televisions and game consoles in the bedroom is also a problem," she said. "It sets up the brain to see the room as an entertainment zone rather than a quiet, sleepy environment."

Losing just one hour's sleep can reduce a child's performance at school, the study published in the Journal of Pediatric Psychology found.

"Even modest differences in sleep duration, accumulated over a few days, can affect critical cognitive and emotional functions in children," the study authors wrote.
