The American Heart Association says children spend too much time in front of the screen and it urges parents to significantly reduce the amount of time their children spend using their phones, computers, tablets and video games.
Children and adolescents between the ages of 8 and 18 spend an average of more than 7 hours a day watching the screen.
AHA's new warning suggests parents limit their child's screen time to up to two hours per day.
For young children between the ages of 2 and 5, it is recommended to limit one hour per day.
The study linked screen time to increased sedentary behavior in children and adolescents.
While there is no long-term evidence to link screening time to increased risk of health conditions such as cardiovascular disease and high cholesterol, there is growing evidence that this is related to obesity, CBS News medical contributor
Tara narura explained.
Trend news live: Narula told CBS This Morning that the Tony Award 2019 deadly crane collapse trophy hunting documentary "Women's World Cup" "We think children start eating snacks in front of the screen . "
"They didn't notice the clues that might tell them they were full and didn't need to continue eating.
They were sort of eliminated.
"On their devices, children will also be exposed to unhealthy food ads.
In addition, blue light on the screen can hinder their ability to fall asleep, and lack of sleep can lead to a risk of obesity.
Experts acknowledge the challenges posed by limiting screen time, especially given how social media and the Internet are intertwined in daily life.
Of course, not all media and digital technologies are harmful to children.
"Of course, it can introduce them to ideas, information, current events, and even health education that they may not be able to get normally," Narula said . ".
"It can also connect them to people who may have lived very far geographically, such as family and friends, and allow them to participate in school projects and assignments.
"However, parents need to step in and set limits.
"The key is that parents need to be what we call a 'media mental '.
"We really need to be involved in teaching your child the media is beneficial, but that's how you use the media in a healthy way," Narula said . ".
Parents also need to encourage their children to play outside and have face --to-
Face interaction with peers.

Free areas such as no screen time for bedrooms and media
Free time, including no equipment on the table, is also beneficial.
Perhaps, most importantly, Narula urges parents to be fully present when they are with their children.
"When you're with your kids, you really need to put down your phone or tablet and talk to them and get engaged because they know what you're doing," she said.
