Why being glued to your smartphone is bad for you and even worse for your children

Roughly half of all smartphone users dont just like their devices, they cant even imagine life without them.

According to a recent report by Gallup, 46 percent of smartphone users say they cant imagine their lives without a smartphone.

Smartphones emerged as a mass-market product less than a decade ago, Gallups Lydia Saad wrote about the report. Yet already 46 percent of American smartphone users have what might be called smartphone amnesia.

The report also found women are more likely to feel this way than men. The same goes for younger Americans versus old.

As a result, women under 30 are the most likely of all gender/age groups to feel this way, Saad explained.

While the social implications of such a shift have been well-documented, social scientists have become increasingly concerned with one aspect of our lives that smart devices seem to be impeding: parenting.

According to The New York Times Jane E. Brody, cellphones, tablets and laptops dont only act as a distraction for parents, though they do that too, their use also acts as a form of training for their children.

Young children learn by example, often copying the behavior of adults, Brody wrote. I often see youngsters in strollers or on foot with a parent or caretaker who is chatting or texting on a cellphone instead of conversing with the children in their charge.

Such behavior, according to Brody, is a lesson for children in how not to be social.

The negative impact of screen-glued parents goes beyond just having "Angry Birds" obsessed children. As Brody wrote in a previous column, what she calls screen addiction is doing some very serious damage on youth.

Parents, grateful for ways to calm disruptive children and keep them from interrupting their own screen activities, seem to be unaware of the potential harm from so much time spent in the virtual world, Brody wrote. Those harms include poor social interaction skills and even subpar school performance.

When we are with our children, we need to be with our children, pediatrician Jane Scott wrote in The Washington Post last year. Not with them except for the part of us thats reading emails, tweeting and checking Facebook.

It seems that for many parents, imagining a life without a smartphone may be hard, but the consequences of living constantly glued to a screen are even worse.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
