Teenage actor Gaten Matarazzo III was born with a rare genetic disorder that affects bone development. And ever since his Netflix series "Stranger Things" became a hit, public interest in the condition has shot up, a new study finds.
The disorder, called cleidocranial dysplasia (CCD), affects only about one in a million people, according to the U.S. National Institutes of Health. Caus...
The more often young teens turn to social media, the more prone they are to eating disorders, new research suggests.
While the study does not prove social media use causes eating disorders, it raises a red flag, said study author Simon Wilksch. He's a senior research fellow in psychology at Flinders University, in South Australia.
Even infants are now watching screens, and as they grow so does the time they spend doing it, two new studies show.
In fact, watching TVs, computers, smartphones, tablets or electronic games occupies about an hour a day of an infant's time and increases to more than 150 minutes by age 3. That's way beyond what's recommended, the researchers said.
Bingeing on social media isn't good for any teen, but new research has pinpointed three ways in which hours spent on Instagram, Twitter, Snapchat and Facebook may harm the mental health of young girls in particular.
"Almost all of the influence of social media on mental health could be explained by the three mechanisms examined -- namely experiencing cyberbullying, sleeping for less t...
You might be more apt to seek out a face-lift, a new nose, hair implants or a boob job if you're a fan of posting selfies on social media, a new study reports.
Adults who regularly use social media are more likely to consider getting plastic surgery to improve their online appearance, particularly if they prefer photo-heavy sites and apps, the researchers found.
Many parents think that watching TV helps their young children fall asleep, but new research finds the opposite is true.
Researchers looked at 470 children aged 3 to 5 in Massachusetts and found that those who watched less than one hour of TV per day got 22 more minutes of sleep at night -- nearly 2.5 more hours per week -- than those who watched more TV on a daily basis.
You've probably seen headlines screaming that a favorite star is packing on the pounds. Tyra Banks, Jessica Simpson, Jennifer Lawrence -- no matter how thin, no celebrity seems immune from "fat-shaming."
Now, research shows the trend could have a ripple effect, making the non-famous feel bad about their bodies, too.
"Fat-shaming is socially acceptable and it's so common we d...
The old saying, "TV rots your brain," could have some validity for folks as they age.
In a new study, middle-aged people who watched television for more than 3.5 hours a day experienced a decline in their ability to remember words and language over the next six years, British researchers found.
What's worse, it appears that the more TV you watch, the more your verbal memory ...
If you're in a frequent tug of war with your kids over turning off their gadgets, it could be the tactic you use when you try to persuade them to disengage.
It turns out that giving 1- to 5-year-olds a time warning that screen viewing is about to end makes the transition away from a tablet, smartphone TV or other device more painful, according to University of Washington researchers.<...
Kids can be as strongly influenced by TV commercials as by the shows themselves, and many studies have found that tempting food ads have a particularly harmful effect, contributing to childhood obesity.
While the government has stepped in with nutrition guidelines for manufacturers, these are largely voluntary and, therefore, not enforceable. So it's up to parents to be vigilant.
When it comes to analyzing the effects of watching reality TV, well, it's complicated. While some see these shows as a brief escape from daily life, they can have negative effects on some viewers, including impressionable teens.
Researchers asked 1,100 girls aged 11 to 17 about their viewing habits. On the one hand, watching reality TV was tied to increased self-esteem and the level o...
Too little sleep. Not enough exercise. Far too much "screen time."
That is the unhealthy lifestyle of nearly all U.S. high school students, new research finds.
The study, of almost 60,000 teenagers nationwide, found that only 5 percent were meeting experts' recommendations on three critical health habits: sleep; exercise; and time spent gazing at digital media and television...
If you're worried that too much "screen time" could be sapping your child's intelligence, new research suggests you might be right.
Kids with the sharpest intellects spent less than two hours a day on their cellphones, tablets and computers, coupled with 9 to 11 hours of sleep and at least an hour of physical activity, the study found.
Photo-editing tools that make people look more perfect online than in real life may be a health threat, medical experts warn.
The tidal wave of altered photos on social media is changing perceptions of beauty. And that can trigger a preoccupation with appearance that leads to risky efforts to hide perceived flaws, researchers suggest. Those efforts include behaviors like skin altering...
News reports on suicides may be quickly followed by a bump in suicide rates -- especially if they contain details that sensationalize the tragedy, a new study finds.
The research adds to evidence of a phenomenon known as "suicide contagion." It happens when vulnerable people identify with a person who died by suicide, and then see that route as a viable solution to their own problems....
Parents who take refuge in their smartphones when their kids throw a tantrum may, in the long run, make matters worse, a new study suggests.
The study, of 183 couples with young children, found that stressed-out parents often turned to their electronic devices when dealing with their kids. And when that was a pattern, their kids' behavior typically worsened over the next several month...
