Screen time has many affects on people of all ages. Screens can affect you r sleep, vision, and get you addicted. There are so many other affect but on the sticks out in my mind is social skills. According to this article, "

Social skills. Online experiences can build community and foster communication and creativity. But as Screenagers points out, tweens and teens might hide behind the screen to avoid tricky or awkward conversations, like approaching a crush or making new friends. “Rather than challenge themselves to do that in person, they go to the screen for a diversion,” Ruston says. That lack of face-to-face interaction can also feed online bullying.

Child behavioral expert Dr. Jennifer Cross explains why screen time should be limited for kids and why some screens are better than others.

Consider this: Nearly half of all children 8 and under have their own tablet device and spend an average of about 2.25 hours a day on digital screens, according to Common Sense Media.

What is all this screen time doing to kids' brains?

This week, a study published in the Journal of the American Medical Association Pediatrics found that screen time may be associated with delayed development in young children. The findings were based on parent reports of screen time use at 1 year and developmental skills at ages 2 and 4 years from a group of nearly 8,000 young children. According to data, using a validated screening tool, 1-year-olds who were exposed to more than four hours of screen time per day showed delays in communication and problem solving at ages 2 and 4. Also, more screen time for 1-year-olds was associated with developmental delays in fine motor and personal and social skills at age 2.

This research supports several previous studies that have shown a correlation between the amount of screen time among young children and the presence of developmental delays particularly in communication and problem-solving skills. A landmark National Institutes of Health (NIH) study that began in 2018, for example, found that children who spent more than two hours a day on screen-time activities scored lower on language and thinking tests, and some children with more than seven hours a day of screen time experienced thinning of the brain's cortex, the area of the brain related to critical thinking and reasoning.

"There is emerging evidence that there may be some structural brain changes associated with greater exposure to screen time as a young child," says Dr. Jennifer F. Cross, attending pediatrician and a developmental and behavioral pediatrics expert at NewYork-Presbyterian Komansky Children's Hospital. "If young children spend most of their time engaging with an iPad, smartphone, or the television, all of which are highly entertaining, it can be hard to get them engaged in non-electronic activities, such as playing with toys to foster imagination and creativity, exploring outdoors, and playing with other children to develop appropriate social skills."

Health Matters spoke with Dr. Cross, also an assistant professor of clinical pediatrics at Weill Cornell Medicine, about the impact of screen time on kids' developing brains and what parents and caregivers can do.

We know that kids have easy access to screens, now more than ever. But how do screens affect early childhood development?
For young children, especially those under the age of 3, development is happening rapidly. Young children learn by exploring their environment and watching the adults in their lives and then imitating them. Excessive screen time may inhibit a child's ability to observe and experience the typical everyday activities they need to engage with in order to learn about the world, leading to a kind of "tunnel vision," which can be detrimental to overall development.

When I see children walking with a parent or being pushed in a stroller, they are often playing on a smartphone or a tablet and not paying attention to anything else around them. They will not learn about the world around them if all they're doing is looking at a smartphone. This will not just affect their ability to learn new things, but also how they interact with others and how language develops.

How does screen time impact a child's ability to learn?
To a young child everything is new. Children need to explore their environment using all their senses to learn about the world, so it is very important that they can interact with three-dimensional spaces and activities. This provides so much more information than watching a two-dimensional picture on a screen.

Studies have shown that children under 2 learn less from a video than when learning from another person, and it appears that although children will watch the TV screen by 6 months, understanding the content does not generally occur until after age 2. It's not that they won't be captivated by what's on the screen, but they're not learning from it.

A child will not learn to stack blocks by watching it on a screen. They will learn by touching the blocks, feeling the texture and weight of different materials, and using trial and error to get one to balance on another. This is early problem solving. So, in addition to limiting screen time, it is important to encourage a child to get involved in experiential learning through play with toys because that fosters early problem solving and creativity.

Language development expands rapidly between 1½ to 3 years of age, and studies have shown that children learn language best when engaging and interacting with adults who are talking and playing with them. There is also some evidence that children who watch a lot of television during the early elementary school years perform less well on reading tests and may show deficits in attention.

"There is also some evidence that children who watch a lot of television during the early elementary school years perform less well on reading tests and may show deficits in attention."
- Dr. Jennifer Cross

Tell us more about how screen time affects language and communication.
Research shows that talking with children in a reciprocal dialogue is extremely important for language development and social interaction. It's that back-and-forth "conversation," sharing facial expressions and reacting to the other person - in real life, rather than "passive" listening or one-way interaction with a screen - that improves language and communication skills in young children.

What age is appropriate to introduce screens?
The American Academy of Pediatrics (AAP) recommends avoiding screens for children younger than 18 to 24 months, except when video chatting with family. The AAP also recommends limiting screen use for preschool children, ages 2 to 5, to just one hour a day of high-quality programming (think Sesame Street or PBS).

When something needs to get done around the house, it can be helpful to have a young child otherwise engaged and entertained. My advice then to parents is to turn on a short TV show like Sesame Street or Daniel Tiger's Neighborhood - something educational and fun that shows characters interacting and playing cooperatively to model good social skills - rather than giving their child a tablet or a phone. And, if possible, it's best to watch the educational programming with the child so you can actively engage with them about what they're watching and learning.

Suggested Screen Time Use By Age

18 Months and Younger
Avoid use of screen media other than video-chatting.

18 - 24 Months
Parents of children 18 to 24 months of age who want to introduce digital media should choose high-quality programming, and watch it with their children to help them understand what they're seeing.

2 - 5 Years
Limit screen use to 1 hour per day of high-quality programs. Parents should co-view media with children to help them understand what they are seeing and apply it to the world around them.

6 - 12 Years
Place consistent limits on the time spent using media and the types of media, and make sure media does not take the place of adequate sleep, physical activity, and other behaviors essential to health.

12 Years and Older
Designate media-free times together, such as dinner or driving, as well as media-free locations at home, such as bedrooms.

How might screens impact a child's sleep?
As humans, our circadian rhythms and our production of melatonin - the sleep hormone - kicks in when the sun sets. But the blue light from screens inhibits melatonin, which can delay sleep. And watching TV or playing games also keeps our brains and bodies more alert and activated and less ready for sleep. (Tablets and smartphones will suppress the melatonin more than TVs because the screen, and that blue light, is closer to the face.)

According to one study, infants 6 to 12 months old who were exposed to screens in the evening showed significantly shorter nighttime sleep than those who had no evening screen exposure.

For preteens and teenagers, excessive use of screens late at night will affect their sleep, and keeping screens out of the bedroom is advised. Too much time spent on social media as well as lack of sleep can affect behavior and cognitive performance in school and interfere with learning. It has also been shown that excessive screen time and sleep deprivation are linked to obesity, which in turn can affect self-esteem and lead to social isolation and more screen time.

How addictive can digital screens be for young kids?
The problem with mobile devices is that they draw you in, and as we all know it's easy to waste time surfing the internet. They are also so portable and ubiquitous that we cannot manage without them. As adults, we understand some of the drawbacks and make a conscious decision to put the phone down, but for 2- or 3-year-olds, who don't have any understanding of these concerns, if they have been exposed to the phone/tablet since infancy, it becomes their norm and they want to do more of it.

We should also be careful of relying on using screens to distract a child from a problem rather than having them figure it out and learn to resolve it themselves. Using a favorite song to distract a young child who has just fallen and scraped their knee might be OK, but having the parent comfort and cuddle with the child and talk to them is better. Using screen time to distract young children who are having trouble sharing a toy will not help them learn how to share and take turns in the future, although it may be a quick fix in the short term.

Are some screens worse than others?
Television isn't as bad as it was once perceived to be as it can be controlled more easily and stays in one place. Tablets and smartphones are much more accessible because they're portable. You can take them anywhere and use them at any time.

I believe YouTube is generally bad for young children. If left to their own devices, children are often better than their parents at finding their favorite videos that link to other videos and can lead to hours of watching endless clips. The largely unregulated nature of the site allows children to watch almost anything; at best there is little educational value, and at worst it can be violent or inappropriate content. Again, the best course of action is to watch with the child so the parent is engaged in finding content that is appropriate and educational.

What tips do you have for parents to limit screen time for kids?
1. Co-watch whenever possible. If children are going to have screen time, the best thing you can do is to watch the show or game with them to help them understand what they're seeing. Comment on things you notice, ask questions about what is happening, if someone on a show is singing a song, sing along with your child. Engage with them and repeat concepts after the show is over so they're more likely to retain that information.

2. Choose media wisely. Look to organizations like Common Sense Media for reviews about age-appropriate apps, games, and programs to guide you in making the best choices for your children.

3. Keep bedtime, mealtime, and family time screen-free. Don't use screens in the car except for long trips, and consider setting a curfew or an agreed-upon time when your family shuts off all screens. Balancing online and offline time is extremely important.

4. Limit your own phone use. Kids will do what they see their parents doing. At a young age, their parent(s) is the most important person in their life, so they will model whatever behavior they are seeing. If they see that you're behind a screen all day every day, then they'll see that it's acceptable and will want to do the same.

5. Emphasize the big three: sleep, healthy nutrition, and exercise. All three are essential to optimal brain growth and development and health and wellness for children and adults alike. And excessive screen time can impact all three. Children who spend more time in front of screens have been shown to eat more fast food and less fruits and vegetables and get less sleep and exercise. Therefore, it is very important to incorporate healthy lifestyle choices as part of the daily routine, as well as limiting screen time.

What Does Too Much Screen Time Do to Kids' Brains?

# data[].attributes.attachment_link.description
Dr. Jennifer Cross, developmental and behavioral pediatrics expert, explains the harmful effects of too much screen time on early childhood development.

# data[].attributes.body
Studies have shown that the use of social media like Facebook and Instagram can trigger the addiction cycle in people. When people "like" or comment on your posts it releases dopamine, happy chemicals in your brain. So can the chats, tags and other communications. Some people get addicted to talking about themselves.

# data[].attributes.attachment_link.readable_text
The screen shows a montage of common images - a group of friends at a noodle joint, half glued to their mobile phones; girlfriends at a Colorado Rockies baseball game posing for selfies. Cut to a group of middle schoolers sitting on a park lawn. A boy with glasses and wiry sandy hair says screen time "distracts you probably from what's more important and yet you still can't get off of it." A slim, ponytailed girl adds, "It pulls you in." The boy agrees strongly, "It pulls you in."

It's a common observation. When physician and filmmaker Delaney Ruston found out that kids spend an average of 6.5 to 8 hours a day looking at screens, as a doctor she wondered: "What impact does all this screen time have on health?"

Ruston investigates this question in her documentary Screenagers, which explores how young people use digital devices and the possible effects on their brains. She discovers digital media use can produce a drug-like effect, felt at any age but most intensely during the teen years. When parents abruptly take away the device from their child, a meltdown typically ensues. "I think so many parents are feeling out of control," Ruston says.

We spoke to Ruston and other experts about the health effects of screen time from childhood through adulthood.
Adults
A 2014 Nielsen report found that adults log a total of 11 hours of screen time a day. Here are some of the ways this might be affecting our health:

Vision. Staring into a screen for extended periods of time can cause "computer vision syndrome." You're probably familiar with the symptoms: strained, dry eyes, blurred vision, and headaches. Poor posture can also cause neck and shoulder pain.

Sleep. Studies link heavy computer and mobile phone use to more sleep disturbances. University of Gothenburg psychologist Sara Thomée, one study's lead researcher, says the blue light from digital devices suppresses the sleep-promoting hormone melatonin, keeping us from having restful sleep.

Addiction and reward seeking. Dopamine, the "feel-good hormone," is part of the brain's pleasure and reward circuits. Playing video games turns on similar brain regions as those linked to cravings for drugs and gambling, Ditto for social media - every time we see a new post or get a reaction to ours, it's like a hit of brain candy.

Weight. Even two hours of TV a day can increase the risk of weight gain, diabetes, and heart disease in adults. (Computer use doesn't seem to have as strong a link.) There are probably several factors to blame, including less active time, less sleep, and seeing more ads for unhealthy foods.

Overall health. Most of the time we're on our screens, we're sitting down. Sitting for hours at a time boosts the risk of obesity, heart disease, type 2 diabetes, and some types of cancer. One study found that spending more than four hours a day in front of a computer or TV more than doubles your likelihood of dying or being hospitalized for heart disease - and exercise won't reduce the risk. Check out our infographic for more information.
Tweens and Teens
During the preteen and teen years, the brain goes through major transformations. This may be why tweens and teens are especially vulnerable to the impacts of screen time on brain function and emotional well-being.

Learning. One study found that kids and young adults who spend a lot of time on TV and video games were twice as likely to suffer from attention disorders. "Anything that affects attention affects learning," says Victoria Dunckley, an integrative child, adolescent and adult psychiatrist and author of Reset Your Child's Brain.

Self-confidence. More time watching videos or other content on digital devices means less time exploring and creating their own experiences, stories, or art. "I think the key to develop self-competence and self-confidence is creating," qualities important for healthy relationships and overall well-being, Ruston says.

Social skills. Online experiences can build community and foster communication and creativity. But as Screenagers points out, tweens and teens might hide behind the screen to avoid tricky or awkward conversations, like approaching a crush or making new friends. "Rather than challenge themselves to do that in person, they go to the screen for a diversion," Ruston says. That lack of face-to-face interaction can also feed online bullying.

Emotions and personality. In 2010, researchers found that kids who logged more than two hours a day in front of a computer or TV screens had a higher chance of psychological difficulties on a standard questionnaire. Studies in young men show that playing violent video games is linked to more aggression and less sensitivity to others. Also, imaging studies have found that internet addiction and game addiction can shrink the brain regions responsible for planning and executive functions, empathy, compassion, and impulse control.,,, It's unclear how quickly or easily the brain returns to a "normal" state after you stop playing video games, Dunckley says. On the other hand, games that reward cooperation and support can lower stress, boost mood, and promote helping behaviors.

Addiction and reward seeking. A recent survey found that 50 percent of teenagers admitted being addicted to their mobile devices. Ruston learned that the brain's dopamine center is extra sensitive during the teenage years, making the rush of playing video games feel even more intense and addictive.

Sleep. Similar to the findings in adults, screen time can have damaging effects on sleep. A 2015 study of 10,000 16- to 19-year-olds in Norway reported that those who clocked in four or more hours of screen time a day (outside of schoolwork and homework) had about a 50 percent higher likelihood of lying awake for an hour or more before finally falling asleep. And according to a recent study, lack of sleep in teens is linked to more risky behaviours like drinking and driving.

Weight and overall health. Just like in adults, watching two or more hours of TV is linked to weight gain in this age group. Studies have also noted higher cholesterol and blood pressure in kids who watch more TV.
Young children
Our kids are swimming in screens. According to a recent study, 92 percent of babies had used a mobile device before their first birthday. Nearly 35 percent have their own mobile device at age 2 and that number is 75 percent among 4-year-olds. Nearly a quarter of kids ages 2 and under have TVs in their rooms, and at age 4, almost 50 percent do. On the other hand, the American Academy of Pediatrics Studies suggest that screen time may be affecting the normal development of fundamental learning, language, and emotional skills.

Learning. Kids younger than 30 months have a limited ability to learn from video, according to some studies., They learn more from live interaction with people and immediate feedback. The American Academy of Pediatrics discourages media use by children under 2 and says there is no proven educational or developmental benefit at this age. Screen time also takes away from unstructured play time, which is important for learning and problem solving.

Language skills. Research has shown that TV can hamper language development in kids by displacing time spent interacting with caregivers. Digital devices might have a similar effect. "TV reduces speech between parents and their infants and toddlers," says David Hill, chair of the American Academy of Pediatrics Council on Communications and Media Executive Committee. "It's really that casual, everyday speech that helps them develop language skills."

Emotional development. Some experts worry that using digital devices as "shut-up" toys to occupy kids during day-to-day tasks like grocery shopping or eating out might prevent them from learning how to regulate boredom, distress, and other impulses and emotions.

Vision. In recent years, many countries are experiencing epidemic levels of myopia, or short-sightedness, and indoor time may be to blame. In Seoul, South Korea, for example, 96.5 percent of 19-year-old men wear glasses. Researchers think it may be due to lack of exposure to sunlight, which might be important for proper eye development. In a 2013 study, teachers at a Taiwanese school made kids stay outside for their entire 80-minute recess period (instead of letting them stay inside). Only 8 percent were diagnosed with myopia a year later versus 18 percent at a neighboring school.

Sleep. Research has linked screen use among children with shorter, lower-quality sleep. A 2014 review paper of school-aged kids and adolescents correlated screen time with poorer sleep. They saw especially strong links between screen time and delays in bedtime, as well as a shorter period of time spent asleep. A study published a year later found that compared with kids who didn't sleep near a small screen (like a cellphone screen), those who did sleep near a small screen reported about 20 fewer minutes of sleep and were more likely to report insufficient rest or sleep.

Weight. Several studies have found that the more TV children watch, the more like they are to be overweight. Kids with TVs in their bedrooms are more at risk, and childhood TV habits affect the risk of being overweight as adults.

The common theme across age groups: More screen time means less time for activities that are good for your health and well-being. The most important question to ask yourself is, "What is screen time displacing?" Hill says. "Is it displacing sleep, communicating with each other as a family, exploring the world and exercising?"

Kids that have more then 2 hours of screen time could cause them behavior problems

# data[].attributes.attachment_link.readable_text
Increased screen time in children could lead to behavioral issues and attentiveness issues in school, according to a recent study.

Investigators found that 2 hours or more of screen time per day resulted in children being 7 times more likely to meet criteria for attention-deficit/hyperactivity disorder and 5.9 times more likely to report clinically significant inattention problems.

Study included 3455 families recruited from Edmonton, Toronto, Vancouver, and Manitoba from the Canadian Healthy Infant Longitudinal Development (CHILD) study. The primary exposure variable for the study was screen-time, which was assessed at 3 and 5 years. The outcome variable for the study was preschool behavior.

Parents reported their child's total screen-time per day, which included watching TV, using a computer, tablet, mobile phone, or playing video games. Investigators created three categories based upon recommendations from the Canadian 24-hour Movement Guidelines. Group 1 had less than 30 minutes of screen time per day, group 2 had between 30 minutes and 2 hours per day, and group 3 reported 2 or more hours of screen time. Investigators adjusted the upper-threshold for screen time at 3 years old to 1 hour per day, based upon the same movement guidelines.

The Child Behavior Checklist (CBCL) preschool version was completed by parents at 5 years at all CHILD sites. Of the 3455 families enrolled in the CHILD study, 2427 children had CBCL data at 5 years old. Authors noted that parents of children with CBCL data reported less screen-time per day than those without CBCL data.

Investigators found significant externalizing behavior problems in 1.2% (28) of children and 2.5% (61) of children exhibited clinical significant internalizing behavior problems. Data on screen time was available for 96% (2322 of 2427) of participants. At 5 years old, 317 (13.7%) children were exposed to 2 hours of screen-time per day and the remaining 2005 met the recommended guideline of less than 2 hours.

Investigators found that children who watched more than 2 hours of screen time per day had increased externalizing, internalizing, and total behavior problems scores compared to children who watched less than 30 minutes. The mean screen time reported was 1.4 hours per day at five years and 1.5 hours per day at 3 years.

The 13.7% of children who reportedly watched more than 2 hours each day were 5 times more likely to report clinically significant externalizing problems and were 5.9 times more likely to report clinically significant inattention problems. Additionally, children with more than 2 hours of screen time per day were 7 times more likely to meet criteria for attention-deficit/hyperactivity disorder.

&#8232;"The two big takeaways from this study are that children exposed to more screen time, at either age three or five years, showed significantly greater behavioral and attention problems at age five, and that this association was greater than any other risk factor we assessed, including sleep, parenting stress, and socioeconomic factors," said Sukhpreet Tamana, PhD, study author and a postdoctoral fellow in the Department of Pediatrics at the University of Alberta.

Investigators noted several limitations within their study. First, because the screen time information was parent-reported it could not be validated against objective measures. The investigators were unable to determine if the media content, or screen type were important predictors of behavioral morbidity. More than 84% of the sample population met the recommended 10 to 13 hours of sleep guideline, which limited the investigators ability to examine the impact of sleep duration on behavior.

This study, " Screen-time is associated with inattention problems in preschoolers: Results from the CHILD birth cohort study," is published in PLOS ONE.
